Description

Composition, application and cosmetic capable of improving skin self-care force Technical Field The invention relates to the field of cosmetics, in particular to a composition capable of improving skin self-care, application and cosmetics. Background The skin is the largest organ of the human body and has mainly four barrier functions, namely microbial, chemical, physical and immune barriers. The interconnections between them constitute a complete barrier system and a powerful defense system. However, infants and children are not yet developed completely, and the skin is structurally and functionally different from that of adults, and is thin in stratum corneum, rich in capillary network, less in sebum secretion, loose in intercellular lipid and weak in resistance. If the nursing is improper, symptoms such as dryness, itching, redness and the like are easy to appear, and severe symptoms such as dermatitis, eczema and the like can be caused. The peony seed oil is vegetable oil extracted from peony seeds, and the unsaturated fatty acid content is up to 92%. Contains abundant linoleic acid and linolenic acid, which are the main components of cell membrane and intercellular lipid for constructing skin barrier, and participate in the formation of horny barrier, and can reduce inflammation and improve allergy. The seaweed oligosaccharide substance is gradually applied to the development of cosmetics due to the nature, nutrition, no toxicity and no irritation, and has the effects of moisturizing skin, removing free radicals, resisting ultraviolet radiation and the like. The seaweed oligosaccharide molecular structure has a large number of polar groups such as hydroxyl groups or carboxyl groups, can form hydrogen bonds with water molecules, can be crosslinked into a network structure, and shows good water absorption. Meanwhile, the trehalose has good film forming performance, a layer of uniform film can be formed on the surface of the skin, the evaporation of moisture on the surface of the skin is reduced, the moisture is dispersed from basal tissues to the stratum corneum, the stratum corneum is induced to be further hydrated, and the moisture of the skin is preserved, so that the skin moisturizing effect is achieved. In the prior art, the following documents are available for the application of a combination of vegetable oils and oligosaccharides in skin care: Publication number CN117243840A, the subject is a fullerene repair moisturizing cream, and the patent application of the preparation method and the application discloses that the cream contains trehalose, brown alginate oligosaccharides, maltotetraose, white pond flower seed oil, jojoba oil and the like; Publication number CN117959235A, the subject is a composition for regulating skin microecological balance and its application, the said humectant is selected from any one or combination of at least two of polyalcohol, hyaluronic acid, sodium hyaluronate, trehalose, ceramide, betaine, seaweed extract, hydroxypropyl cyclodextrin, the said emollient is selected from any one or combination of at least two of white pool flower seed oil, sunflower seed oil, mango seed ester, grape seed oil, sweet almond oil, butter tree fruit oil, jojoba seed oil, avocado oil, squalane, caprylic/capric triglyceride, polydimethylsiloxane, isononyl isononanoate, cetyl ethyl hexanoate or hydrogenated polyisobutene; The combination of the seaweed oligosaccharide substance and the functional vegetable fat can improve the self-care ability of the skin, but the improvement ability of the seaweed oligosaccharide substance and the functional vegetable fat cannot reach the expectations of the project. Based on this, the present disclosure is proposed. Disclosure of Invention The invention aims at providing a composition for improving skin self-care, which adopts lactoferrin modified by phosphate groups to improve the repair effect of seaweed oligosaccharides and functional vegetable oil and fat on skin, the composition of the invention not only can relieve the dry skin function, but also can improve the physical barrier and immune barrier functions of the skin and the self-protection capability of the skin. It is a further object of the present invention to provide the use of the composition. To achieve the above object, the present invention provides a composition for improving skin self-care, comprising the following components: 6-8wt% of a phospho-group modified lactoferrin solution; 1.2-1.5wt% of algae oligosaccharides; 1-2wt% of vegetable oil with skin barrier repair function; Emulsifying agent and water in balance; the concentration of the phosphate group modified lactoferrin in the phosphate group modified lactoferrin solution is 1.2-2wt%.
