Introduction

Thioglycolic Acid is an organic compound that contains a thiol group (-SH) and carboxylic acid. It is a colourless liquid. Ammonium Thioglycolate and Thioglycolic Acid are used as hair dyes and colors. Ammonium thioglycollate is a key ingredient in many hair care products, such as hair relaxers, perms, and straightening creams. It is a reducing agent that helps to break down the hair's disulfide bonds, making it easier to achieve desired hair texture, whether straight or curly.

Application

Ammonium thioglycolate is used in Straighteners.

Function: Hair waving/straightening agent; reducing agent.

In salts of Thioglycolic Acid, a dose of ~20 mg/cm2 in emulsion is applied to scalp after applying a 10-fold skin/hair partition factor. Concentration corresponds to a max. of 11% Thioglycolic Acid, pH =9.5. Duration of application is 45 min, frequency is every 8 weeks.

Ammonium thioglycolate is used in Permanent waves

Function: Hair waving/straightening agent; reducing agent

In salts of Thioglycolic Acid, a dose of *20mg/cm2 in a watery solution is applied to the scalp after applying a 10-fold skin/hair partition factor. Concentration corresponds to a max. of 11% Thioglycolic Acid, pH =9.5. Duration of application is 30 min, frequency is every 8 weeks

Advantage

One of the main benefits of using ammonium thioglycollate is that it is less harsh on hair than other chemical treatments, reducing the risk of damage and breakage. It is also known for its ability to create long-lasting and beautiful curls or straight hair.

Note

When using ammonium thioglycollate, following the instructions provided carefully is important to avoid over-processing the hair, which can lead to damage and breakage. The percentage of ammonium thioglycollate needed will vary depending on the desired results and the product used.
