Thioglycolic Acid for Discoloration Treatment

12

I found some more information, this time from a .gov site, and also for the sodium salt. I don’t see how the properties would be significantly different for the calcium salt.

Please, please, carefully consider this information in situations where you decide to mess with mercaptoacetic acid or it’s salts:

THIOGLYCOLIC ACID

Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. (ERG, 2008)

Reactivity Profile
THIOGLYCOLIC ACID is readily oxidized by air (NTP, 1992). Reacts readily with other oxidizing agents as well in reactions that may generate toxic gases. Incompatible with diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials may generate heat and toxic and flammable gases. May react with acids to liberate hydrogen sulfide. Neutralizes bases in exothermic reactions. Reacts with cyanides, sulfites, nitrites, thiosulfates to generate flammable and toxic gases and heat. Reacts with carbonates and bicarbonates.

First Aid
SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.

And now about the sodium salt:

THIOGLYCOLIC ACID, SODIUM SALT

Health Hazard
SYMPTOMS: Symptoms of exposure to this compound may include dermatitis, erythema, edema, subcutaneous hemorrhages and caustic poisoning.

ACUTE/CHRONIC HAZARDS: This compound is a local irritant and may be absorbed through the skin. When heated to decomposition it emits toxic fumes. (NTP, 1992)

First Aid
SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.

INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.

Hey again everyone!

Much the same as it had on 8/20. I have not applied the MSP since that post; a mixture of time constraints and illness. Had the diagnosis not so closely sounded of hypochondriacism and histrionics, I’d have sworn I came down with the H1N1 flu! As sometimes the closer one comes to their goals the less driven they are to attain them (‘which proves I’m not a complete nut job,’ as memento once said), the significant improvement in coloration attained early in my trials was enough to pacify any sense of urgency. While I’m still very interested to test other OTC TGA-containing products and, even moreso, locate a highly concentrated TGA solution with as few secondary ingredients as possible, I’ve been giving serious thought to EDTA. The product comprised of pure calcium disodium EDTA I mentioned in my previous post is heading my way via FedEx. I plan to create a 50/50 solution of water and EDTA and submerge my penis for 20 minutes (arbitrary); I’ll write with greater detail once the product arrives!

I’m probably inappropriately applying the term relative to it’s definition in chemistry jargon. :) My father is a wildly accomplished chemical engineer, and by virtue of proximity I’ve picked up a bit of the lingo. Sadly, I don’t understand most of it (haha!). The issue may be moot, though, if this company’s product gives any indication of the typically prepared TGA solution: http://www.sigmaaldrich.com/catalog…=0&QS=ON&F=SPEC

Their solution mixes TGA with water; ethyl alcohol a no-no, then?

"The use of formulations containing chelating agents, such as EDTA or desferroxamine (already proposed by some authors, see Meyers in 1966 and Goldman in 1992) give variable, uncertain results, likely due to their difficult diffusion through cutis, since topical way is the most preferred”

The first page of the referenced 1966 Meyers paper: http://ang.sagepub.com/cgi/pdf_extract/17/1/66

As is indicated in the opening paragraph, the aim of Meyers’ therapy is application of a topical chelator for the purpose of removing hemosiderin (right up our alley!). The following sentences are from the fourth paragraph: “Disodium ethylene-diamide tetraacetate, also designated as disodium ethylene diamide tetraacetic acid, endrate, or EDTA, is a safe chelating agent. It was applied topically in the treatment of dermatitis appearing in nickle [sic] and cobalt miners by Rostenberg and Perkins in 1951. Grant used it as a collyrium to dissolve calcified corneal opacities.” “In 1954, Kurtin and Orentreich used EDTA in the chelation deactivation of nickel ion in allergic ezcematous dermatitis.” Although the author does not specify exactly how effective the treatments were, one could infer from the phrasing that each application was successful since they were plainly introduced to support the author’s hypothesis. I have not researched how nickel and cobalt-caused dermal pigmentation differ in either their physical manifestations or treatment mechanisms compared to iron-caused dermal pigmentation. Intuition suggests dermal embedding of the offending elements is, physically speaking, either equal to or more deeply placed than iron. The rationale: Hemosiderin deposition occurs in the papillary dermis, the highest layer of the dermis directly below the dermal/epidermal junction. Insofar as nickel and cobalt deposit themselves in the dermis, the highest possible placement is, obviously, the papillary dermis. Whether or not they may be deposited even lower, reaching into the reticular dermis or, even lower, the subcutis (if physiologically possible), is inconsequential; so long as the placement is dermal, nickel and cobalt rest either alongside hemosiderin or below it.

OK, OK, I’ve made the point; so what? Well, so long as EDTA effectively chelates cobalt and nickel when applied topically, if the solution (most likely water-based*) is reaching low enough in the dermis to chelate the ions, and EDTA’s chelating ability of an iron complex like hemosiderin is roughly equal to that of nickel and cobalt, EDTA could prove a viable—and far simpler—means of ousting discoloration! I’ll return to this subject shortly.

At least not in “[s]olutions having concentrations comprised in the 0.5-15% w/w range”, as it is claimed in the patent.

Depilatory products typically contain between 3-5% TGA. (Source: Input the following into Google search, barring quotation marks: “Depilatory creams showed an average content between 3 and 5%”. The first result displays the same sentence within it’s hyperlink summary, part of a science journal.) Judging by it’s strength relative to many other depilatory solutions and cremes I’ve tried throughout the years, I’d wager the MSP I use (recounted in detail in post #13) falls nearer to 5% than 3%. Perhaps the secondary ingredients are effective as buffering agents, going beyond their duty as post-depilation skin conditioners to lessen TGA-skin contact and keep the disulfide-busting action from dipping into the hair follicle (80% chance). Or, more simply, perhaps TGA in concentrations of 3-5% simply isn’t terribly sensitizing (95% chance). Yeah, I know: Most likely, both commingle to some effect. I imagine upwards of 15% TGA could get wild, and by 20% you may as well just go the route of TCA and reap the benefits of resurfacing along with discoloration elimination. Nevertheless, TGA in the quantity present in the platinum-canned MSP product is easily tolerated. While all due precautions should be taken before slathering MSP on your stuff in toto, I’m confident you’ve nothing to fear.

What would be the chemistry of the ligand exchange (thermodynamically and kinetically)?

I assume that understanding the specifics of the chemical reaction would go some way in determining the efficacy of TGA’s hemosiderin chelation. While no chemical process can possibly transpire unperturbed in textbook, regimented causation within such a complex environment as the human body, knowing the possibility exists is still a must.

Unfortunately, I have no idea what you just said, hahaha! Experience and supposition has led me to believe there’s quite definitely something to TGA’s depigmenting activity; if we can nail down TGA’s exact relationship to hemosiderin, definitively assess it’s epithelial permeability and determine the ideal concentration suited to our purpose, we’ve done it!

Of course, it could just as well be EDTA, too. Nothing personal, TGA!

Speaking of which—hey EDTA: I really want to find a champion in you! I left the topic earlier after mentioning EDTA’s (inferenced) effectiveness for nickel and cobalt chelation bodes well for our aspiration. Hopefully EDTA’s iron-chelating activity is equal in strength to the aforementioned two; since hemosiderin finds it’s home at the highest altitude of the dermis, if we can assume EDTA can reach the dermis well enough to effectively rid of pigmentation caused by nickel and cobalt-induced dermatitis, all that remains is confirming EDTA’s iron-complexing profile. *Sigh* I know I’m taking for granted that EDTA’s effectiveness was evidenced in something as abstract as the style of an author’s syntax, but my conviction in my logic endures! The 1966 Meyers paper is available for complete review for a $32.00 fee; a bit steep, in my opinion. To be honest, it makes no difference to me anyhow. At this point, I’m so encouraged by the extent of my research that I would take part in the EDTA experimentation if even the next page of the .pdf read: “EDTA is useless when applied topically for the treatment of hemosiderin-induced varicose staining. Give it up, Bill.”

Oh yes: You referenced the patent’s downplaying of EDTA’s effectiveness. “Difficult diffusion through the cutis,” they say. Interestingly, in the very same article (the often referenced 1966 Meyers paper) EDTA was successful in treating dermis-oriented conditions. In addition, the phrasing of “.give variable, uncertain results.” contains not only two nebulous adjectives, but implies by the one, “variable,” that there were positive results to accompany the negative. Inasmuch as EDTA is gentle and unlikely to cause harm by topical application, could a fitting strategy be to immerse your penis in a high-concentration EDTA/water solution as often and for as long as possible? If one wishes to maximize results and hasten resolution by experiencing as many effective episodes of topical chelation as possible, such would make sense.

I don’t enjoy relying on faith when the possibility of assuredness is always lingering around the corner. Faith implies an aspect of hope, which is expectedness without an idea of causation. Assuredness is expectedness with a firm idea of causation; while you can be assured and still end up being wrong, your former conception of the truth (before amending) held true to valid modes of logic. On the other hand, faith implicitly relies on an ideated result without a causal mode of logic. As much as I’d love for Godzilla to be real, the mode by which he could exist is not an explanation I can provide logically. Thus, it’s just a hope, and a fantastical one at that.

I hope TGA turns out to be discoloration’s swan song. I really hope EDTA proves the super-simple alternative to a depilatory system. I know natural penis enlargement—some jelqs, a few manual Ulis, and a bit of downward and upward manual stretching—gives me a larger penis. :)

Thanks for the responses—talk to you all later!

OK :) Just to make things clear then, the formulation should’ve been “ethanol based” (preferred) or “ethyl alcohol based”. Just saying “ethyl based” implies that the solvent can be any organic compound containing the ethyl group (e.g. Ethyl nitrate, ethyl bromide etc.)

Still, I am very concerned about the potential health risks of thioglycolic acid.

To mods: please, please post at the beginning of the thread the following warning regarding this compound:

THIOGLYCOLIC ACID

Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. (ERG, 2008)”

Please, do it, there is the risk of some fellow forumers having serious negative side effects from this product. We really do not want this to happen.

Bill,
If you are so brave to try this compound on yourself - this is something that is truly to be appreciated. But we should not be responsible for potential causing of adverse health effects to other people!

I’ve been using Veet hair removal cream for a few years. Http://www.veet.com/
Veet is a potassium thioglycolate product and is applied to millions of legs everyday with apparently little impact on their owners’ health. My skin hasn’t melted off yet anyway.
I presume that the % concentration contained in depilatory creams is sufficiently low to avoid the “severe injury/death” stuff.

.. Do you guys remember the golden age of smoking advertising? You do, right?
“The Marlboro Man”.. I’m sure you remember it.. Fuck it, I still smoke Marlboros!
But decades after the launching of the (legitimate) campaign.. Guess what.. Three people involved in that campaign died of lung cancer.
It took DECADES from the start of the campaign until it became obvious that the product that was advertised was a class I carcinogen.

Beware!

Millions of people got cancer! Millions of legs may get adverse health effects! As they say in the UK Garage kind of music: “things are never quite the way they seem”:

Veet proves that there’s no immediate, or at least immediately manifest, damage to be seen in applying this stuff to your skin. Is it a potential health hazard? We know that sunlight is a huge health hazard. I wouldn’t treat this case differently to someone who, for example, recommended sunlight in order to cure discoloration. Risk management is a matter of personal preferences.

BTW Bill seems to have seems to be switching over to a different chelating method? Changing methods like this half way through surely invalidates his whole experiment ?

Hey. I haven’t much time to type, but I would like to quickly clarify where I am in this process. I haven’t applied MSP since, if recollection serves me, 8/14—18 days ago. Since then I’ve continued my PE regimen without alteration: 150 jelqs interspersed with a 30-second manual Uli every 50 strokes in the A.M., 300 jelqs interspersed with a 30-second manual Uli every 50 strokes in the P.M. I also do ten 30-second manual stretches in the P.M., sporadically incorporating an indeterminate amount of 30-second stretches into my A.M. Routine when whim finds me. Kegels performed frequently at random intervals. Discoloration still unchanged since regular MSP application ceased, halting at a subjectively appraised 60% reduction in discoloration severity as compared to pre-application state. Continued PE in the absence of MSP application has not prompted discoloration to return to it’s pre-application state; working theory is that soft tissues are now conditioned to the workload, drastically reducing (if not eliminating completely) any minor petechiae or more substantial purpura. While PE-induced growth has slowed, perhaps indicating fibrous tissue strengthening to accompany that seen in the soft tissues, PE gains since this active session began (roughly 9 months ago) are holding fast at ~1.5” length and ~.5” girth gained. Given my penis has surpassed my length goal (8”) by .5” and is nearing my girth goal (6”), PE ambition has greatly dwindled.

What has not dwindled, appropriately, is my desire to rid of the last of this discoloration! Of course, since my moderate success with TGA even that flame has dimmed. What needs to be made clear, though, is that as it stands from my own subjective appraisal, TGA is effective and, in formulations similar to that of my chosen product, safe to use as a gradual reducer of dermal hemosiderin deposition. Careful as I was with my monitoring of progress and elimination (to the great extent possible) of variables contributing to either the hindrance or prominence of discoloration removal, I am 95% certain my discoloration lessened to the degree observed on account of TGA.

Now, I may decide (when interested) to next begin testing a topically-applied high concentration EDTA solution solubilized with water. Whether or not it proves effective does not in any way bear any relevance to TGA’s track record, save for some unforeseen long-lasting chemical mechanism by which TGA interferes with EDTA’s action. :) In any event, I will keep you guys posted every step of the way of each action taken in the interests of ridding of this dastardly discoloration.

I’ll try and post at greater lengths when able. TTYL!

Bill

Any updates to this? Anyone else use it with success? Thanks.

I had a noticeable dark spot that was bothering me on the underside of my shaft. I put a few coats of wart remover on it and it faded nicely.

Although it did hurt and it did leave some tight, smooth, shiny skin behind that I eventually was able to exfoliate. It’s back to normal now though.

Yeah, thanks. I have used wart remover in the past but I don’t like it because on one application a scab broke off when healing and now I have a permanent ugly scar on my cock.

Oh wow that sucks. How long did you leave the remover on there for? I did it for a minute or so and it burnt to much so I took it off. It left a smooth patch on my skin but like I said I just exfoliated it off.

I’m going to get some of this Gold Magic Shaving Powder and try it.

I really really wish this thread hadn’t died. I am utterly convinced that my bad discoloration is hemosiderin located in the dermis. Since it is located in the dermis, salycylic acid has never and will never get to it. So I feel I have no option left but to do a TCA peel. That will suck because, aside from the basic obvious reasons why putting powerful acid on your genitals sucks, it will result in making it impossible for me to do any PE for a long time.

If only the TGA, or perhaps even more promisingly, the EDTA had proven to work. That would be amazing. But I feel like when these threads die it means the ideas they had proved to not work out.

Is that how any of the rest of you see this? Did anyone give EDTA a try?
