Technical Field
[0001] The invention belongs to the technical field of cosmetics, and particularly relates to a collagen cosmetic with a moisturizing effect and a preparation method thereof. Background Art
[0002] There are many cosmetics containing collagen ingredients on the market, such as creams, essences and sprays. Collagen is a biological polymer substance and the most abundant protein in the human body, accounting for about 25%-33% of the total protein in the human body. It weaves into an elastic fiber network in the skin, providing elasticity and firmness to the skin, and plays the role of a deep reservoir, providing moisture to the epidermis, with a super moisturizing effect.
[0003] For example, the patent application number is 202310891483.8, which discloses a collagen peptide cosmetic and its preparation method. The collagen peptide cosmetic includes the following components by weight: 3-5 parts of collagen peptide, 5-10 parts of modified chitosan, 8-15 parts of moisturizer, 6-8 parts of emulsifier, 0.1-0.2 parts of preservative, 3-5 parts of thickener, 3-4 parts of pH regulator, and 50 parts of water. The modified chitosan is chitosan modified with kojic acid, and collagen peptides are introduced by grafting copolymerization. The invention proposes kojic acid-modified chitosan, grafting chlorokojic acid ester on the primary hydroxyl group at the C-6 position and the secondary hydroxyl group at the C-3 position of the chitosan molecular chain, and then grafting collagen peptides on the C-2 amino group of the kojic acid-modified chitosan molecular chain, and then introducing collagen peptides and chlorokojic acid esters with moisturizing and whitening effects into the formula, and finally achieving the technical effect of improving the moisturizing and whitening of cosmetics.
[0004] However, since the above-mentioned cosmetics contain modified chitosan, and this modified chitosan is chitosan modified by kojic acid, although it is safe to control the amount of kojic acid added in cosmetics to be less than 2%, excessive addition may cause skin allergies and dermatitis, and is not suitable for use by people with sensitive skin, which limits the scope of use of the cosmetics. Therefore, we need to propose a collagen cosmetic with a moisturizing effect and a preparation method thereof to solve the above-mentioned problems, so that it can have a moisturizing and whitening effect while also being suitable for use by people with sensitive skin, thereby increasing the scope of use of the cosmetics.
