Matrix raw material is a kind of main raw material of skin care products. They are the basic substances that make up all kinds of skin care products such as creams, creams, serums, etc., and determine the texture, stability and sensory experience of the product. Although they are not as flashy as the active ingredients, they are the cornerstone of the efficacy of the product.
Fat: A fatty acid glyceride composed of fatty acids and glycerol, usually extracted automatically from plants. They provide lubrication, soften the skin, help lock in moisture and prevent dryness. Vegetable oils can be divided into drying oil, semi-drying oil and non-drying oil. The oils used in skin care products are mostly semi-drying oil and non-drying oil. Common oils in skin care formulas include olive oil, coconut oil, castor oil, cottonseed oil, sweet almond oil, peanut oil, corn oil, rice bran oil, tea seed oil, sea buckthorn oil, avocado oil and so on.
Animal fats usually contain some highly unsaturated fatty acids, compared with vegetable fats, their color, odor and so on are poor, but also there are easy to be oxidized problems. Animal fats often used in skin care products are mink oil, egg butter, lanolin, lecithin and so on.
Waxes: Waxes are esters composed of high-carbon fatty acids and high-carbon fatty alcohols. This ester plays a role in skin care products to improve stability, adjust viscosity, reduce greasy feeling, form a protective layer to reduce water loss and so on.
Plant wax generally includes carnauba wax, candelilla wax, Jojoba wax, wood wax and so on. Animal wax is beeswax, also called beeswax.
Hydrocarbons: hydrocarbons are collectively referred to as hydrocarbons, which are compounds composed of carbon atoms and hydrogen atoms, mainly including alkane cycloalkanes, olefins, alkynes, and aromatic hydrocarbons. Hydrocarbons are insoluble in water. The boiling point of hydrocarbons is high, mostly above 300℃. According to the structure of hydrocarbons, they can be divided into three categories: aliphatic hydrocarbons, alicyclic hydrocarbons and aromatic hydrocarbons. In skin care products, it is mainly used to prevent the evaporation of water on the skin surface and improve its moisturizing effect. Hydrocarbons commonly used in skin care products include liquid paraffin, solid paraffin, lignite wax, ground wax Vaseline and so on.
Synthetic raw materials: synthetic raw materials refers to a variety of oils, waxes and other raw materials through the processing of modified oil and wax, its composition and raw materials are similar to oil, while maintaining the advantages of oil, in the purity, physical properties, chemical stability, microbial stability and skin irritation and skin absorption and other aspects of better performance, so it is a common raw materials for skin care products. Commonly used synthetic oil raw materials are squalane, silicone oil, polysiloxane, fatty acid, fatty alcohol, fatty acid ester and so on.
Powder raw materials are mainly used in powdered cosmetics, such as talcum powder, fragrance powder, powder, lipstick, blush and eyeshadow. Silty ingredients play a variety of roles in cosmetics, including providing cover, increasing smoothness, promoting adhesion, oil absorption, sun protection, and improving product ductility. Silty raw materials are usually divided into the following categories:
Inorganic powder: such as talc powder, kaolin, bentonite, calcium carbonate, titanium dioxide, titanium dioxide, diatomite, etc., mainly used to provide product smoothness and ductility, so that the skin feels more delicate.
Organic powder: zinc stearate, magnesium stearate, polyethylene powder, microcrystalline cellulose, polystyrene powder.
Gum raw materials are water-soluble polymer compounds. Most of these substances can expand into colloids in water, so that the solid powder can be bonded and formed, and can also be used as an emulsifier to stabilize the emulsion or suspension, in addition, there are films, thickening gels and other effects. The colloidal raw materials used in cosmetics are mainly divided into natural and synthetic and semi-synthetic three categories.
Natural water-soluble polymer compounds: usually derived from plants or animals, such as starch, plant gums (such as gum Arabic), animal gelatin, etc. The quality of these natural sources of colloidal raw materials can be unstable due to changes in climate and geography, and there is a risk of contamination by bacteria or mold.
Synthetic water-soluble polymer compounds: polyvinyl alcohol, polyethylene pyrrolidone, polyacrylic acid, etc., stable properties, low irritation to the skin, low price, so instead of natural water-soluble polymer compounds become the main source of colloidal raw materials. It is often used as a adhesive, thickener, film forming agent and emulsifying stabilizer in cosmetics.
Semi-synthetic water-soluble polymer compounds: the most common are methyl cellulose, ethyl cellulose, carboxymethyl cellulose sodium hydroxyethyl cellulose and guar gum and its derivatives.
