Thickeners are an important part of cosmetic formulas. They can not only change the product The viscosity can also modify the stability, feel and flow properties of the product. There are several options for organic thickeners to adjust the viscosity of oils or solvents.
One type is long-chain alcohol, usually cetyl alcohol and stearyl alcohol or a mixture of the two, which are also used in sticks, creams and lotions. The addition of long-chain alcohols to the mesophase of oil-in-water emulsions helps stabilize the emulsion by providing a vehicle effect. It provides system viscosity without bringing about the viscosity that may be caused by adding wax components. The long chain base can provide excellent compatibility in non-polar oils.
Today, the supplier of cetyl alcohol and stearyl alcohol will give you a brief introduction to the cetyl alcohol, stearyl alcohol and A mixture of the two, cetearyl alcohol:
Cetyl alcohol:
A white crystal with a rose aroma. The melting point is 49.6℃, the boiling point is 344℃, 190℃ (2.0kPa), the relative density is 0.8176 (20/4℃), and the refractive index is 1.4392 (20℃). Soluble in ethanol, ether, benzene, chloroform, acetone, insoluble in water.
Suitable for use in various cosmetics as a matrix, especially suitable for creams and lotions; in medicine, it can be directly used in W/O emulsifier creams Body, ointment base, etc. The raw materials of Pingpingjia can also be used as defoaming agents, soil and water moisturizers, gas chromatography fixatives (color-forming agents); they can also be used as raw materials for the production of alcohols, amides and sulfonated products for detergents; and as heat preservation agents for rice fields.
Stearyl alcohol:
White flakes or particles. Melting point 59.4-59.8℃ (freezing point 57.95℃), boiling point 210℃ (2kPa) 170-171℃ (0.266kPa), relative density 0.8124 (59/4℃), refractive index 1.4346 (45℃). Soluble in alcohol, benzene and chloroform, insoluble in water.
It is widely used in daily chemicals, textiles, printing and dyeing and other industries. It is a raw material for manufacturing surfactants, emulsifiers and various additives. Used as a base (emulsifier) for creams and lotions in cosmetics. Stearyl alcohol has stronger emulsion thickening properties than cetyl alcohol.
Cetearyl alcohol:
Alias Cetearyl alcohol is a mixture of solid fatty alcohols containing stearyl alcohol and cetyl alcohol, in the form of white solid, flakes or granules. Among them, stearyl alcohol and cetyl alcohol account for more than 90% of this mixture, and there are also small amounts of other alcohols. The specific proportion is about 50%-70% stearyl alcohol and 20%-35% cetyl alcohol.
For use in cosmetics, plastics, leather, textiles, synthetic detergents and other industries. It can be used as a lubricant; emulsifier; tackifier; as a base in cosmetics, especially suitable for creams and lotions; in medicine, it can be directly used in W/O emulsifier pastes, ointment bases, etc. It stabilizes emulsions and has a co-emulsifying effect, thereby reducing the amount of surfactant required to form a stable emulsion.
