Application of Tris |CAS:77-86-1|in the field of cosmetics

Tris is widely used in the preparation of buffers in biochemistry and molecular biology experiments. In addition, Tris can also be used in the field of cosmetics. CN 111297735A discloses a cosmetic composition containing natural wax. The cosmetic ingredients include ethylene glycol, propylene glycol, glycerin, carbomer, caprylic/capric triglyceride, stearate, octyldodecanol, Sorbitan, glycerides, palmitic acid, Tris and 1,2-hexanediol. The specific preparation steps are as follows:

1. Heat a mixture composed of 20% by weight of natural wax composition, 45.1% by weight of purified water, 5% by weight of ethylene glycol, 5% by weight of propylene glycol, and 5% by weight of glycerin to 75℃ and use a homogenizer stir at 2500rpm for 5 minutes;

2.Combine 7% by weight of caprylic/capric triglyceride, 5% by weight of octyldodecanol, 2% by weight of stearate, 2% by weight of sorbitan, and 0.5% by weight of glyceride , 0.5% by weight of the palmitic acid mixture was heated to 80℃ and dissolved; the resulting mixture was added to the product of the first step, and a homogenizer was used to stir for 5 minutes at 3000 rpm;

3. Add 0.45% by weight of carbomer to the result of step 2, and use a homogenizer to stir at 4000rpm for 5 minutes to maintain the temperature;

4. After cooling the product of step 3 to 45-50℃, add 0.45% by weight of Tris and 2% by weight of 1,2-hexanediol to it, and use a homogenizer to stir at 2500rpm for 3 minutes, The mixture was then cooled to below 30℃。

This technology can easily use a large amount of wax at a low melting point, can also overcome the shortcomings of easy melting at high temperatures, and is easy to use even in water systems. This technology not only improves the method of producing natural vegetable waxes, but also maintains stability. The water-in-oil cosmetic composition that can best display the properties of natural vegetable waxes can improve moisturizing power and skin texture.
