The main components and the effects of the invention are as follows:

1. cyperus oil: the essential oil extracted from the cyperus esculentus roots is rich in vitamin E and linoleic acid, can prevent skin damage, can be added into skin care products and cosmetics as a skin conditioner, can enhance the barrier function of skin, has the effects of moisturizing, improving the glossiness of the skin and tendering the skin, and keeps the skin in a healthy state.

2. Titanium dioxide: the whitening powder has higher whiteness, belongs to inert mineral substances, has no activity, thus having good safety and no anaphylactic reaction, and is commonly added into foundation make-up and sun screen to be used as white powder for color matching, thereby having the effect of whitening skin color. In addition, titanium dioxide has the efficacy of a sunscreen.

3. Polydimethylsiloxane: the lubricant has good lubricating property, can form a layer of uniform protective film with water resistance after being coated on skin, does not have any sticky or greasy feeling, and has good glossiness. The performance of resisting ultraviolet radiation is good: it is not oxidized and deteriorated under ultraviolet rays to cause skin irritation. The antistatic performance is good: tests show that the skin static electricity after being wiped by the skin care cream containing polysiloxane is completely eliminated, and the skin care cream has obvious dustproof effect. The air permeability is good: even the formation of a silicone film on the skin does not affect sweat discharge. It has the functions of slowly releasing and fixing fragrance, so that it has long fragrance-retaining period, high stability, chemical inertia and good compatibility with other components of cosmetics, especially active component. Has no toxicity, odor or taste, no irritation or allergy to skin, and high safety.

4. Mineral oil: the oil extracted from petroleum is colorless, odorless and low in sensitivity. Has antistatic effect, and can be used as solvent and emollient in cosmetics. The mineral oil is divided into cosmetic grade and medicinal grade, and the cosmetic grade mineral oil has high safety and small irritation, and can also achieve the effect of resisting oxidation.

11. Isododecane: it is commonly used as an emulsifier and solvent in skin care and cosmetic products, and is a hydrocarbon, which acts as a solvent to provide a product with a fresh texture, which is easy to apply, and which reduces or avoids loss of skin moisture.

12. Isobutyl methacrylate/bis-hydroxypropyl dimethicone acrylate copolymer: has excellent film forming, dispersing, adsorbing and lubricating abilities, is used as a film forming agent, a conditioner and the like, and is applied to the field of personal care products.

13. Polyglyceryl-3 diisostearate: can be used as emulsifier in cosmetic.

14. Glyceryl polyether-26: is glycerin adduct of 26 mol of epoxy ethylene, and is used as a humectant and a lubricant. Are stable over a wide range of pH values for cosmetic and cleaning products, have good compatibility with cationic, nonionic and anionic surfactants, and are very effective moisturizers in creams and lotions. The glyceryl polyether-26 greatly improves the sticky and skin-friendly feeling of the product in a semi-dry state, and is particularly suitable for products containing macromolecular polymers such as essence, gel and the like.

15. Magnesium sulfate: the external preparation can improve rough skin, and can be used as filler and viscosity control agent in cosmetic, fill depression and pores, and smooth skin.

16. Silica: is commonly used in foundation and makeup base, has slight coverage, and can increase skin smoothness. And silica is highly safe in cosmetics and non-irritating to the skin.

17. Alumina: the product can be used as adsorbent and thickener in cosmetic, has high safety on skin, and can make mica surface show soft pearl luster.

18. Tocopherol acetate: the vitamin E derivative belongs to vitamin E derivatives, is commonly used as an antioxidant in cosmetics, has good antioxidant effect, is an oil-soluble natural substance, is a good nutritional moistening agent for skin, can avoid rancidity oxidation of oil and stabilize the oil when being added into skin care products and cosmetics. The composition has good effects in moisturizing and maintaining connective tissues, and protecting skin from ultraviolet rays, and can soften skin touch and retain skin moisture, promote wound healing, prevent inflammation, prevent skin from rough and chapped, improve black spots, and has a low safety risk index, thus being widely used.

19. Mica: belongs to natural mineral substances, has luster, and can be made into matt shape. The cosmetic is mainly used as a coloring agent, and the brightness of the cosmetic is increased, so that the skin texture and the touch feeling are increased after the cosmetic is used. The mica can not be absorbed by skin, and can not cause any damage to skin due to mineral substances, and is mainly used for enhancing the shiny visual effect of cosmetics.

20. Triethoxyoctylsilane: is a silicone resin, and is mainly used as a binder and an emulsifier. The product is used as surface treating agent for inorganic filler or pigment such as titanium dioxide, and has improved affinity and wettability with paint, adhesive, sealant, etc.

21. Magnesium stearate: can be used as self-emulsifying matrix of water-in-oil type cosmetic emulsion, can be used as colorant in various cosmetics and other daily chemical products, can effectively inhibit degradation of DHA in the product, and has good antiaging and moisturizing effects.

22. Phenoxyethanol: it is a low-grade skin sensitive preservative, and the most widely used preservative in cosmetics. Has slight aromatic smell, has certain emulsification effect and has great influence on the viscosity of the product.

23. Ethyl hexyl glycerin: has the functions of moisturizing, antibacterial property and strong stability, is often used as a solvent or an additive, can improve the moisturizing effect of the product, and has the effect of smoothing skin. The component can also enhance the antiseptic effect of phenoxyethanol, reduce the dosage of antiseptic components in the product, and increase the safety of the product.
