Description

Plant composition, plant sunscreen lotion and preparation method thereof

Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to a plant composition, a plant sunscreen lotion and a preparation method thereof.

Background

Sunscreen has been a topic of concern in the cosmetic field, and the stability, safety and effectiveness of sunscreen agents are issues that must be addressed. The sunscreen cosmetics on the market at present mainly adopt a mode of combining physical protection, chemical protection or physical and chemical protection. Physical sunscreens achieve sunscreen by shielding ultraviolet light through reflection, but generally are thick and heavy, tend to whiten after being applied, and have relatively weak protective ability. Chemical sunscreen agents achieve the sunscreen effect by absorbing ultraviolet light and converting the ultraviolet light into heat which is released, and are lighter and thinner than physical protection, but the sunscreen agents have a small molecular weight, can permeate into the skin, are potentially dangerous to the skin, and may cause many skin problems such as free radicals, photoallergy, contact dermatitis, and the like.

CN111743822A discloses a sunscreen composition consisting of litsea cubeba oil and resveratrol, and the sunscreen effect has good ultraviolet absorption effect on UVB wavelength. The litsea cubeba oil and resveratrol are compounded to show a sunscreen effect, but the composition has poor effects of inhibiting the generation of melanin, replenishing water and moisturizing.

CN106852840A discloses a method for preparing an anti-allergic sunscreen cream, which is prepared by mixing paeonol, hyaluronic acid, arbutin, glabridin, astaxanthin, snail protein powder, apple extract, pine bark extract, aloe extract, melatonin, yeast extract, arnica extract, diferuleic acid, liquorice extract, seaweed extract, salvia miltiorrhiza extract, grape seed extract, towel gourd extract, clove extract, vitamin C, hyaluronic acid, mulberry bark extract, wild chrysanthemum extract, fishy extract, butterfly extract, glycine, emulsifying wax, perfume and ionized water Sunscreen and antiinflammatory effects.

CN109662928A discloses a skin care composition with sun-screening and repairing effects, and an application and a preparation method thereof. The composition comprises 0.1 to 3 weight parts of plant soothing agent; 0.01-1.0 part by weight of a tocontamine; 0.1-1.0 weight part of hydrolyzed yeast protein; 0.01-0.5 weight parts of green alga extract; 0.01-0.1 part by weight of witch hazel extract; 0.01-0.1 weight part of tremella polysaccharide; 0.1-1.0 part by weight of oat glucan; 0.1-1.0 part by weight of allantoin; 0.01-1.0 weight part of composite ceramide; 0.01-1.0 part by weight of sunflower unsaponifiable matter; 1.0 to 10.0 parts of glycerol, 1.0 to 10.0 parts of methyl propylene glycol, 0.01 to 1.0 part of sodium hyaluronate, 0.1 to 10.0 parts of betaine and 0.1 to 1.0 part of panthenol.

Therefore, the skin care product with the functions of efficiently absorbing UVB ultraviolet rays and removing free radicals has wide market prospect.
