The present application provides a liposome having a double-layer membrane structure and use thereof. The liposome comprises a double-layer lipid membrane formed from (a) a phospholipid, (b) dipotassium glycyrrhizinate or a cationic surfactant, and (c) a polyoxyethylene sterol ether having a hydrophobic end embedded in the double-layer lipid membrane. The liposome of the present application has excellent stability and can be stably present in a formulation form. Furthermore, a liposome having a double-layer lipid membrane structure with excellent stability can be obtained without using a polyol.

The present patent application discloses a recombinant human collagen type I and its use. The amino acid sequence of the recombinant human collagen type I is shown in SEQ ID No: 2. The recombinant human collagen type I has good cell proliferation activity, cell migration activity, cell adhesion activity (all better than full-length recombinant human collagen type I or commercially available human collagen), and is easy to produce. The recombinant human collagen type I is expected to have the effects of whitening, moisturizing, soothing and repairing, and can be applied in the fields of cosmetics, external use drugs, skin care products, health care products, tissue engineering materials, medical devices and the like.

The application relates to the technical field of supramolecular, in particular to a supramolecular salicylic acid and a preparation method and application thereof, the preparation method comprises the following steps: mixing salicylic acid, a ligand and an auxiliary agent, stirring and ultrasonicating to obtain the supramolecular salicylic acid; the ligand comprises L-lysine or arginine; and the molar ratio of the salicylic acid to the ligand is 1:1. The supramolecular salicylic acid prepared by mixing the salicylic acid and the ligand in a certain proportion and dissolving them in the auxiliary agent improves the solubility, stability and permeability of the salicylic acid. The supramolecular salicylic acid prepared by the application has good solubility and stability, strong permeability, small skin irritation, a simple and environment-friendly preparation method and is suitable for large-scale production.

The application discloses a skin-nourishing powder cream composition and a preparation method thereof, and the skin-nourishing powder cream composition is a water-in-oil emulsion system, and contains, in parts by weight, 22.5-62.5 parts of an oil phase component, 4-14 parts of a powder component, 15-50 parts of an aqueous phase component and 0.1-2 parts of a skin conditioner; and the application uses high-content natural plant oils such as jojoba seed oil and olive fruit oil and high-quality emollient esters such as caprylic acid / capric acid triglyceride as core oil phases, thereby replacing a large amount of mineral oil or volatile silicone oil used in traditional powder creams. The plant oils are rich in unsaturated fatty acids and antioxidant components, and can provide long-lasting moisturizing, repair the sebum membrane and relieve dryness for the skin.

This invention provides an oil-controlling composition, its preparation method, and its application. The composition comprises extracts from *Eryngium sibiricum*, sunflower seed, *Edelweiss*, and *Saussurea involucrata*. Cosmetic products containing this composition exhibit excellent oil-controlling, moisturizing, and soothing / repairing effects.
