Sunscreen spray and preparation method thereof

Abstract

The invention discloses sunscreen spray and a preparation method thereof. The spray is prepared from, by weight, 4-8 parts of haematococcus pluvialis extract, 3-6 parts of glycyrrhiza glabra extract,3-5 parts of centella asiatica extract, 1-3 parts of wall breaking selenium-enriched yeast, 2-6 parts of zinc oxide, 1-2 parts of titanium dioxide, 0.2-3 parts of fullerenes, 2-4 parts of squalene, 6-10 parts of avocado oil, 0.3-0.7 part of dragosantol, 0.1-0.5 part of lycopene, 2-3 parts of tranexamic acid, 6-8 parts of sheep placenta polypeptide, 5-10 parts of butanediol, 0.1-1 part of hyaluronic acid, 0.6-1 part of ceramide, 0.4-0.6 part of nicotinamide, 0.03-0.6 part of allantoin, 0.2-1 part of rose pure dew, 2-4 parts of UVA absorbent, 0.1-1 part of UVB absorbent, 2-3 parts of O / W type emulsifier and 150 parts of water. The method packs and embeds surfaces of three nanoparticles through the emulsification of oil and composite nano-suspension, enhances the skin-fitting property of thesunscreen spray, prolongs the contact time of spray particles with skin epidermis, improves the sun protection factor and the whitening effect, and utilizes multi-component synergy to repair sunburnedskin.

Description

technical field [0001] The invention belongs to the technical field of cosmetic production, and in particular relates to a sunscreen spray and a preparation method thereof. Background technique [0002] UVA, the wavelength is between 320-400nm, also known as long-wave dark spot effect ultraviolet rays. 98% of UVA in sunlight can penetrate the ozone layer and clouds to reach the surface of the earth, can penetrate deep into the dermis of the skin, destroy elastic fibers and collagen fibers, and at the same time activate tyrosinase to form melanin, making the skin tanned, sunburned, and overwhelmed. premature aging. UVB, with a wavelength between 290-320nm, also known as medium-wave erythema effect ultraviolet rays, can destroy the lipid layer of the epidermis, denature nucleic acids and proteins in epidermal cells, and cause skin redness, swelling and peeling. Long-term exposure can cause changes in melanocytes , forming sun spots that are difficult to remove. [0003] In ...

AI Technical Summary

Problems solved by technology

Existing sunscreen products mainly block ultraviolet rays through physical shading, chemical absorption, or a combination of the two. They do not start with the biosynthesis pathway of melanin, inhibit tyrosinase activity, and block the transmission of melanin. In addition, no matter which sunscreen skin care product is used No product can achieve 100% UVA and UVB isolation effect. After summer exposure, the skin must be repaired and nourished in time

Compared with sunscreen and sunscreen lotion, sunscreen spray has a lighter texture, no sticky feeling, and is more refreshing and comfortable, but the sunscreen layer formed on the epidermis is thinner, and the sunscreen performance is greatly reduced
