Synthetic oil and stable raw materials in cosmetics refer to oils and waxes, which are processed and synthesized from various oils and fats. These synthetic oils and fats are similar in composition to natural oils and oils, retaining the advantages of natural oils, but with significant improvements in purity, physical shape, chemical stability, microbial stability, skin irritation, and skin absorption. It is superior to natural oils and is therefore widely used in various cosmetics. Commonly used synthetic oils and fats are squalane, lanolin derivatives, polysiloxanes, fatty acids, fatty alcohols, fatty acid esters, and the like.
Squalane is produced by hydrogenation of squalene in deep-sea shark liver oil. It is a colorless, transparent, odorless, odorless, non-toxic oily liquid. The main components are myristic acid, soybean meal, squalene, and shark — Alkane, etc. Squalane has good permeability, lubricity, and safety and is often used in high-grade cosmetics such as creams, lotions, lotions, lipsticks, hair conditioners, and eyeliners.
The lanolin derivative is a series of derivatives of lanolin. Including wool alcohol, lanolin acid, pure wool wax, acetic acid wool wax, acetylated wool alcohol, polyoxyethylene hydrogenated lanolin, and so on. Wool is light yellow to light brown waxy solid, slightly odorous, insoluble in water, better than lanolin, widely used in various cosmetics, such as baby products, dry skin, and skincare products, creams, lotions, etc. Linolenic acid has an excellent moisturizing effect on the skin and is commonly used in shaving creams. Pure wool wax has excellent stability, easy to absorb, and good emollient. Therefore, it is mainly used for emulsifying products such as creams and ointments. Acetylated wool wax is mild, safe, and reliable. It is often used in lotions, creams and sunscreen cosmetics. It is mixed with mineral oil and used in baby oil, bath, lipstick, hair oil, and hair gel. Polyoxyethylene hydrogenated lanolin is a milky white, slightly odorous, waxy solid obtained by the addition reaction of hydrogenated lanolin with ethylene oxide. High stability, excellent water absorption, suitable for perm, hydrogen peroxide paste, etc. It is also used in lipsticks, conditioners, and various creams and emulsion products.
Polysiloxanes are also known as silicone oils or silicones. It and its derivatives are high-quality raw material for cosmetics. It has physiological inertness, and excellent chemical stability is odorless, non-toxic, non-irritating to the skin, and has unique skincare functions. It has lubricating property, anti-ultraviolet radiation effect, good gas permeability, the slow-release effect on flavor and fragrance, proper antistatic and distinct dustproof function, high stability. It does not affect matching with other ingredients. Commonly used are polydimethylsiloxane, polymethyl phenyl siloxane, cyclic polysiloxane, and the like. Because of its excellent softness, polydimethylsiloxane often replaces traditional oily raw materials such as paraffin and vaseline in cosmetics to make cosmetics, such as creams, lotions, lipsticks, eyeshadows, mascaras, shampoos, etc. Polymethylphenylsiloxane is a colorless or light yellow transparent liquid. It has excellent skin permeability, and good skin feels after use. It can increase the softness of the skin, deepen the color of the hair, and maintain natural luster. It is commonly used in high-grade skincare products. And beauty cosmetics. The cyclic polysiloxane has low viscosity and good volatility and is mainly used in cosmetics, such as creams, lotions, bath oils, shampoos, colognes, stick cosmetics, and sweat products.
There are various fatty acids as raw materials for cosmetics, such as lauric acid, myristic acid, palmitic acid, stearic acid, isostearic acid, fats, and the like. A fatty acid is a raw material for cosmetics, mainly combined with potassium hydroxide or triethanolamine to form soap as an emulsifier. Lauric acid, also known as dodecanoic acid, is a white crystalline waxy solid. In cosmetics, lauric acid, sodium hydroxide, and zinc hydroxide are generally made into sodium laurate, zinc laurate, and soap is formed as a cosmetic. Emulsifier and dispersant, it has excellent foaming and stable foam. It is mainly used in shampoo, facial cleanser, and shaving cream. Myristic acid and lauric acid are used in the same range. They are mostly used in the raw materials of facial soaps and shaving creams, such as magnesium myristate, sodium myristate, and potassium myristate. Palmitic acid is a natural material for creams, lotions, surfactants, and fats and oils. Stearic acid and fat are raw materials for creams, hair creams, lotions and lipsticks, and surfactants.
As a raw material of fats and oils, fatty alcohols are mainly C12-C18 high-grade fatty alcohols, such as lauryl alcohol, whale alcohol, stearyl alcohol, etc. as humectants; propylene glycol, glycerol, sorbitol, etc. can be used as a viscosity agent, a reducing agent, a qualifier Solvents and perfumes are used in cosmetics. Lauryl alcohol is rarely used directly in cosmetics and is often used as a surfactant. W-propanol is widely used as an essential oil and stable raw material for creams and lotions. Stearyl alcohol is the primary raw material for preparing creams and lotions and is used in the production of lipstick products in combination with cetyl alcohol.
Fatty acid esters are mostly formed by the esterification of higher fatty acids with low molecular weight monohydric alcohols. Its characteristics are miscible with oil, low viscosity, good elasticity, good permeability to the skin, and widely used in cosmetics. Butyl stearate is the raw material for nail polish and lipstick; isopropyl myristate and isopropyl palmitate can be used in hair care, skincare, and cosmetics; isooctyl stearate is used primarily in cream products.
