Whitening sunscreen cream containing marine oligosaccharides

Abstract

The invention relates to the field of daily cosmetics, in particular to whitening sunscreen cream containing marine oligosaccharides. The whitening sunscreen cream comprises raw materials in weight proportion as follows: 1%-2% of an emulsifier, 20%-40% of pure water, 5%-20% of alginate oligosaccharides, 10%-20% of olive oil, 5%-10% of glycerin, 10%-20% of butylene glycol, 5%-20% of chitosan oligosaccharides, 1%-10% of chitosan, 10%-20% of collagen, 5%-10% of vitamins and 0.5%-1% of an antibacterial agent. According to the whitening sunscreen cream, hydroxyl groups, amino groups and other polar groups in all molecules of the chitosan oligosaccharides and the chitosan can form hydrogen bonds with water molecules, and the hydrogen bonds are combined with a large amount of water; further, sugar chains of the chitosan oligosaccharides and the chitosan can be interwoven mutually to form a net, and a higher water retention function is realized; finally, by means of the antibacterial and antioxidation functions of the chitosan oligosaccharides and the ultraviolet ray absorption function of the alginate oligosaccharides, the sunscreen and skin repair functions can be realized effectively.

Description

【Technical field】 [0001] The invention relates to the field of daily cosmetics, in particular to a whitening sunscreen containing marine oligosaccharides. 【Background technique】 [0002] The skin is the primary protective barrier of the human body, which can protect the human body from external stimuli. In the hot summer, when the exposed part of the skin is exposed to excessive sunlight, the acute phototoxic reaction of the skin on the exposed part will cause erythema, edema and peeling, which will not only cause unbearable pain, but also cause skin epidermal keratinocyte necrosis , and the release of mediators causes dermal blood vessels to dilate, causing tissue edema, and then melanocytes accelerate the synthesis of melanin under the strong sunlight, thereby darkening the tanned skin. To protect the skin from sunburn. People often use cosmetics for moisturizing and sun protection, and also use cosmetics to whiten the skin for beauty. Most of the existing sunscreen and...
