Let you learn about it together Four common raw materials for emulsified cosmetics:
1. Grease and wax:
Stearic acid and glyceryl monostearate:
Stearic acid, also known as stearic acid, is a white flake, bead or block solid at room temperature. It plays an emulsifying role in skin care products such as ice cream and cold cream, turning it into a stable and white paste.
Glyceryl monostearate (monoglyceride for short) is an auxiliary emulsifier and also has an emollient effect.
2. Palmitic acid, myristic acid and its isopropyl ester:
Palmitic acid is also known as It is hexadecanoic acid. Color solid, insoluble in water, slightly soluble in petroleum ether, soluble in ethanol. Raw materials for the production of candles, soaps, greases, softeners and synthetic detergents, and raw materials for fabric softeners
Myristic acid is also called myristic acid. Used as raw materials for soaps, soaps, detergents, cosmetic surfactants and chemical fiber oils; manufacturing emulsifiers, waterproofing agents, curing agents, polyvinyl chloride heat stabilizers and plasticizers, etc.
Meat Isopropyl myristate (IPM) and isopropyl palmitate (IPP) are synthetic light and flowing oily substances with better skin permeability than other moisturizers.
3. Cetyl alcohol and stearyl alcohol:
White solid, soluble in ethanol and ether, Insoluble in water. It can be used as an auxiliary emulsifier, also has emollient and thickening effects, and can form an adsorption film. Promote skin hydration, give the skin a soft and smooth feeling, and prevent the cream from becoming thinner and thicker during long-term storage and storage.
4. Mineral oil and petroleum jelly
Non-polar, high-carbon hydrocarbons with boiling points above 300 degrees Celsius, with straight-chain saturated hydrocarbons as the main components, are resistant to oxygen and heat. It has high stability and is not prone to corruption and rancidity. Vaseline can be used as a raw material for making medical ointments and skin protection ointments; as an ingredient in cosmetic creams, balsams, cosmetic oils, etc.; in the textile industry, it can be used to make emulsions, etc.
