GLs Lightening Process--Update

cant you just picture her in a white lab coat with rubber gloves and some goggles doing the evil laugh? jk SAS. we love you gurl. keep up the good work

Thank's SAS. I would have been surprised if you had not tryed this after all the research you did I can't wait to here your results. You go Sas, ya little mad scientis

okay, so Leia did an excellent job of translating everything.  a few things I think I can add to the discussion if we are considering trying this.

1) wrt long periods of time with peroxide.  yes you will want to change it out because the peroxide degrades.  But you need to be careful how you dispose of the the peroxide solution because peroxides degrade to ethers when exposed to oxygen and ethers explode.  Hydrogen peroxide is the safest one.  heavily diluting with water mitigates the problem.  But using care is advised.

2) Formaldehyde is nasty carcingenic stuff.  I'm not afraid of chemicals as a general rule but please use care (ventilation gloves etc).

3) I think all of the acids listed would be available in powedered forma dnt hen you could mix with water for what you needed.  this has many advantages.  You don't have to store acids in your house just their salts.  shipping water is heavy/expensive and that's what most of it would be.  shipping acids is expensive, because of the risks, but shipping their salts is much less risky and therefore much less expensive.

4) I have this contraption that I actually bought commercially for my lab.  Oddly enough it also uses Iron Sulfate.  more importantly it uses basically a fish tank heater and fish tank bubbler to keep the temp even and the agitation going.    You could easily mod a standard fish tank bubbler to meet your needs.  buy a bunch of cheap teflon (cause the acids won't degrade it) tubing.  hook it into the fish tank bubbler.  poke lots of tiny holes along the length of the tubing.  arrange the tubing on the bottom of your experimental chemistry vessel.  voila steady mild agitation.  I doubt fish tank heaters need explanation but I'm sure one can be aquired cheaply and easily for the necessary temp range.

okay I'm going to review this againa nd see what I forgot.

Someone should ask Mochachip for help. I think she works in a chemistry lab.

Too bad for our purposes this stuff needs to be agitated for days. If it was just for an hour like with the cashmere shomeone could set a crockpot on my washing machine

Can we make this a a sticky?  Like permanantly stuck to the top of the forum?

This was another Italian cashmere lab that responded to my letter on the human hair depigmentation.
They also want to conduct the tests for me and them of course work with me and we know what that means...... $$$$
Our first guy is the only one who has given us something to work with.


We know you are trying to develop a process to de-pigment human hair and we really think we can help you. Our Group has been working on cashmere's teatments for 20 years and we have now a special know-how about them.
We have Overmeyer equipments and we are sure we can succeed in developing a special treatmen for human hair.
At the moment our treatment NA.DE. (NATURAL DEPIGMENTATION) is very requested and it is the most gently lightening process available today.

Please, send us samples and we will be happy to make some trials fo you.

We remain at your complete disposal for further information. Please do not hesitate to contact us.


I wanted to wait for all the companies to respond first before trying all these chemicals.

SRR~where are you? you were going to conducting a test with oxyclean and 10 vol HP. That's been 19 days...........did you have any luck coming up with anything? I haven't seen you on the board again to ask.

yeah, they only use 1-8% max on their testing, and that is over a short period. Soaking for 15-20 days would be using the lowest amount of Hydrogen Peroxide possible. I will have to dilute it big time.

STS~sorry girl, didn't realize you converted the temp already!!
I have to go get a crock pot!!
Or does anyone have one that they can pop some water in, set on low heat and tell me what the temperature is? That would be great!!

No,,.... HCHO 40percent.... that's really high.. That's super high percentage of hydrogen peroxide. Remember, cashmere is actually quite durable, that's why you can make such fine sweaters from it. That paper looks to me like you can soak the hair in 40percent peroxide for 10 or 15 days at room temp. or just above (heat helps) and strip the hair. Think of when you were a kid and spent the day in the pool .... all summer long. Give it a try. Christina

85 degrees C girl!!

I will buy a crock pot this week!!

I believe 85 degrees C, warm and room temps.

Crock pot.....could work. I will have to get one. I don't know what the temps would be on low/med/high. Well there's only one way to find out!!

Heat lamp....can you use a heat lamp for long periods of time?
Aquarium........interesting

STS~I think we will wait for all the companies to respond and then decide the chemicals for use. Thanks girl.....thats a great plus!!
