Embodiment example 1

[0028] Preparation method of sunscreen N1:

[0029] (1) Accurately weigh 100 g of crabapple seed oil, 30 g of Pseudomonas alopecia seed oil, 30 g of maritime pine bark extract, 10 g of snow lotus flower extract and 10 g of Centella asiatica extract, and put them in 250 mL stainless steel Mix well in the container, heat to 65°C, stir with an IKA stirrer at 300 rpm until the solid components are completely dissolved to obtain a light brown transparent liquid, and cool to room temperature to obtain a specific plant composition. Accurately weigh 50 g of the specific plant composition and 50 g of butylmethoxydibenzoylmethane to compound and mix in a 250 mL stainless steel container, heat to 80°C, stir evenly with an IKA stirrer at 300 rpm until the solid components are completely dissolved, and obtain Clear and transparent yellow liquid, cooled to room temperature for later use;

Abstract

The invention relates to a sunscreen composition comprising 1-5% of butyl methoxydibenzoylmethane by mass fraction. The sunscreen composition is characterized by further comprising a plant composition, wherein the mass ratio of the plant composition to the butyl methoxydibenzoylmethane is 1:1, and the plant composition is prepared from plum-leaf crab seed oil, pongamia glabra seed oil, coast pine bark extract, snow lotus herb extract and asiatic pennywort herb by a mass ratio of (6-10):3:3:1:1. The sunscreen composition has the advantages that the light stability of butyl methoxydibenzoylmethane can be improved, the sun protection factor PA value of the product is improved, the sun protection capability of the product is improved, and the shelf life of the product is prolonged.

Description

technical field [0001] The invention relates to the technical field of sunscreen cosmetics, in particular to a sunscreen composition, more precisely a composition capable of improving the performance of sunscreens containing butylmethoxydibenzoylmethane. Background technique [0002] The ultraviolet rays that can penetrate the atmosphere in sunlight and reach the skin usually refer to UVA and UVB. Among them, ultraviolet UVA has a wavelength of 320-400 nm and has strong penetrating power. It can reach the dermis of the skin, destroy collagen and elastin, and cause wrinkles. The main culprit of human photoaging and skin cancer. [0003] Butylmethoxydibenzoylmethane, whose INCI name is BUTYL METHOXYDIBENZOYLMETHANE, is currently known as the sunscreen with the strongest UVA band sunscreen ability. But butyl methoxy dibenzoyl methane itself is not high in photostability, and the molecule is prone to configuration transformation and decomposition. Sunscreen cosmetics with butyl...
