Sodium Thioglycolate, with the CAS number 367 - 51 - 1, is a high - quality chemical product available at the best price. It is a white to off - white powder or crystalline solid. The chemical formula of Sodium Thioglycolate is C₂H₃NaO₂S. It has a molecular weight of approximately 114.1 g/mol.
Solubility is an important parameter. It is highly soluble in water, which makes it easy to formulate in aqueous solutions. The product typically has a purity of over 98%, ensuring high - quality performance in various applications. It should be stored in a cool, dry place away from direct sunlight and sources of heat to maintain its stability.
2.1 Cosmetics Industry
Sodium Thioglycolate is widely used in the cosmetics industry, especially in hair removal products. It works by breaking down the disulfide bonds in keratin, the protein that makes up hair. This weakens the hair structure, allowing it to be easily removed from the skin surface. It is also used in permanent waving solutions to reshape hair.
2.2 Leather Industry
In the leather industry, it is used for depilation. It helps in removing hair from animal hides during the leather - making process. This chemical provides an efficient and cost - effective way to achieve smooth leather surfaces.
2.3 Analytical Chemistry
It is used as a complexing agent in analytical chemistry. It can form stable complexes with various metal ions, which is useful in determining the concentration of metals in solutions through titration and other analytical methods.
3.1 In Hair Removal Products
When formulating hair removal creams, Sodium Thioglycolate should be dissolved in water or other suitable solvents. The concentration usually ranges from 4% - 8%. After dissolving, other ingredients such as emulsifiers, fragrances, and moisturizers can be added. The mixture should be stirred well to ensure uniform distribution. Apply the product to the skin where hair is to be removed and leave it for the recommended time (usually 5 - 10 minutes) before wiping it off.
3.2 In Leather Depilation
For leather depilation, a solution of Sodium Thioglycolate is prepared with a concentration of around 1% - 2%. The animal hides are soaked in this solution for a period of time, typically 12 - 24 hours, depending on the thickness of the hide. The solution should be agitated occasionally to ensure thorough contact with the hair on the hide.
3.3 In Analytical Chemistry
When using it as a complexing agent, a known amount of Sodium Thioglycolate is added to the sample solution containing the metal ions to be analyzed. The solution is then titrated with a suitable titrant until the end - point is reached, which can be detected using appropriate indicators.
4.1 Cosmetics Case
A well - known cosmetic company introduced a new hair removal cream using Sodium Thioglycolate. They conducted market research before the launch, finding that consumers were looking for a more effective and gentle hair removal product. After formulating the cream with the appropriate concentration of Sodium Thioglycolate, they tested it on a group of volunteers. The results showed that 90% of the volunteers reported that the hair was easily removed, and there was less skin irritation compared to other products on the market. The product was then launched successfully and gained a large market share.
4.2 Leather Industry Case
A leather factory was facing challenges in achieving a smooth and hair - free leather surface using traditional depilation methods. They decided to switch to Sodium Thioglycolate. After implementing it, they noticed a significant improvement in the quality of the leather. The hair was removed more completely, and the leather had a softer texture. The production efficiency also increased as the depilation process took less time compared to the previous method.
4.3 Analytical Chemistry Case
A research laboratory needed to determine the concentration of copper ions in a sample of industrial wastewater. They used Sodium Thioglycolate as a complexing agent in
