Phenacetin can be used in hair dyeing products as stabilizer

We all know that phenacetin is an antipyretic and analgesic drug, but do you know? Phenacetin can also be used in hair dyeing products as Phenacetin stabilizer, such as hair gel, hair wax and colorants.

First of all, we need to understand the principle of hair dyeing with hair dye. Simply speaking, hair dye is to open the hair scale of your hair through chemical dye (the hair scale is the outer structure to protect the hair pigment) and carry out chemical reaction between hair dye and the interior of hair to exchange color, so as to achieve the effect of hair dyeing.

There is an oxidant in hair dye: hydrogen peroxide water. Its concentration is 6%, which can make the oxidized dye oxidize and polymerize to produce color. At the same time, it can also decompose the melanin in hair and play the role of decolorization.

So what is the role of phenacetin hair dye?

It can be used as a stabilizer of hydrogen peroxide to prolong the shelf life of hair gel, hair wax and hair dye.

Hair dye products are special cosmetics, and special cosmetics adopt the administrative license registration system. The package label of cosmetics for special purposes must be marked with the Health approval number of cosmetics for special purposes, such as “g20196666”. Phenacetin has not been listed in the list of prohibited components and restricted components in the technical specification for safety of cosmetics.
