Hydroxyapatite

Hydroxyapatite (HAP), also known as hydroxyapatite and basic calcium phosphate, is a natural mineralization of calcium phosphate (Ca5(PO4)3(OH)). However, it is often written in the form of (Ca10(PO4)6(OH)2) to emphasize that it is composed of two parts.

product details

Hydroxyapatite can be used on cosmetic ,food,tooth paste ,mouthwash,oral care etc.

Silicones&silicone emulsions

Silicone oil is a kind of polysiloxane formed by alternating arrangement of silicon and oxygen. It has a silicon oxygen bond (Si-O) chain structure and usually exists in the form of liquid or gel. It has excellent chemical stability and high temperature resistance. Silicone oil has good film-forming properties, hydrophobicity, breathability, and physiological inertness. It can form a soft and breathable protective film on the surface of the skin, keeping the skin hydrated and smooth. Silicone oil is widely used in cosmetics, providing excellent protection and improvement functions.

Emollients
Emollients

Emollients are cosmetic components that help maintain the softness, flexibility, and smooth appearance of the skin. The function of Emollients is to remain on the surface of the skin and provide lubrication within the stratum corneum. Usually filling the space on the surface of the skin, replacing the lost lipids in the stratum corneum, reducing scaly skin, and improving skin appearance.

Vegetable oils

Vegetable oil is a compound formed by the reaction of higher fatty acids and glycerol, widely distributed in nature. It is an oil obtained from the fruits, seeds, and germ of plants, such as peanut oil, soybean oil, flaxseed oil, castor oil, rapeseed oil, etc. The fatty acids in vegetable oils can moisturize and brighten the skin, and are widely used in cosmetics.

Plant extracts
Plant extracts

Using plant roots, stems, leaves, flowers, fruits, seeds, and mushroom fruit bodies as raw materials, the concentrated product is obtained through water/ethanol extraction, filtration, concentration, and drying (spray drying/freeze drying), with targeted enrichment of active ingredients such as flavonoids, polysaccharides, triterpenoids, polyphenols, saponins, and volatile oils, without damaging the structure of the effective substances. Powder extract (mainstream): spray-dried powder, water-soluble, used for solid beverages, tablet pressing, and meal replacement.
