Glyoxylic acid 50% for semi-permanent method for straightening curly, frizzy or wavy hair

Currently, there are three methods used for straightening curly, frizzy or wavy hair.

a. Using a simple treatment with electric plates consisting of two hot plates (at a temperature higher than 100°C). The hair is placed between the two plates and compressed to achieve the desired style.

b. Chemical treatment combined with low-temperature mechanical processing: A chemical substance is applied to the hair, which causes a change in the hair when treated at a temperature below 100°C.

c. Chemical treatment combined with high-temperature mechanical processing: A chemical substance is applied to the hair and treated at a temperature higher than 100°C. Due to the combination of heat and the chemical substance applied to the hair, this technique can cause more significant changes in the hair than those achieved by other techniques.

A semi-permanent method for straightening human hair, comprising the following steps:

a) Applying glyoxylic acid solution onto the hair;

b) Allowing the solution to remain in contact with the hair for 30-120 minutes;

c) Drying the hair with a hair dryer;

d) Using aflat iron set at a temperature of approximately 200+/-30°C to straighten the hair.

If the hair was previously curly or frizzy, Glyoxylic acid can alter the hair’s texture to obtain a straight shape and maintain it for at least six hair washes. The semi-permanent change in the hair’s texture can persist under typical usage conditions and repeated hair washing.

Used in hair straightening formulations, Glyoxylic acid 50% smooth wavy and tight curly hair. When applied with flat iron, it softens natural curls. It provides shiny silk appearance and improve hair maneageability.

  Production method of Glycolic acid 99% Glycolic acid  is an important organic synthesis intermediate and chemical product. As a new type of fine chemical intermediate, it has many uses, as follows: It can be used as a tanning assistant, water disinfectant, milk shed disinfectant, boiler scale remover. Glycolic acid  can be used as a cleaning agent. A mixed acid composed of 2%  glycolic acid  and 1% formic acid is an efficient and low-cost detergent suitable for cleaning air conditioners. It can produce fiber dyeing agents, detergents, welding agent ingredients, varnish ingredients, copper etchants, adhesives, petroleum demulsifiers, metal integrators. Sodium and potassium salts of  glycolic acid  are used as additives in electroplating solutions. Other uses include electrolytic grinding, metal pickling and leather dyeing. It can also be used as a chemical analysis reagent for organic synthesis and as a daily chemical additive instead of fruit acid. 1.  Glycolic acid solution HOCH2CN+
