Problems solved by technology

At present, both organic and inorganic sunscreens are used in general sunscreens, but sunscreen products with high SPF values ​​are prone to thick, sticky, airtight skin, and fast failure. For outdoor sports in the sun, it is often difficult to directly resist High-intensity direct sunlight, and it needs to be replenished every 2 hours on average, which not only easily leads to poor breathing of the skin, blockage of oil outlet, but also easily causes redness, swelling, allergies, dryness and lack of water, and greatly damages the skin

Abstract

The invention provides a natural plant-based cool sunscreen composition and a preparation method thereof. The sunscreen composition is composed of a plant extract matrix and effective sunscreen components, wherein the mass ratio of the effective sunscreen components to the plant extract matrix is 1: 20-25; the plant extract matrix comprises an aloe-phellodendron extract, a hollow carrier, seaweedgel and refined water; the effective sunscreen components comprise nano-zinc oxide, nano-titanium dioxide and nano-boron nitride. The inorganic sunscreen components are uniformly dispersed and loadedon the hollow carrier by reasonably optimizing matching of the raw material, and meanwhile, the outer layer is coated with the breathable maintenance layer, so that the sunscreen composition is cool,refreshing, moist, quick in heat conduction and heat dissipation, beneficial to improvement of skin permeability absorbability and quick moisturizing, and good in comprehensive ultraviolet shielding performance, and can achieve efficient protection.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a natural plant-based cool sunscreen composition and a preparation method thereof. Background technique [0002] With the development of society, consumers' skin care concepts have changed, and they pay more and more attention to sun protection. No matter indoor work or outdoor play, they will apply sunscreen or sunscreen after applying basic care "water and milk". Claimed day cream. [0003] The appearance of sunscreen is white lotion or cream. The mechanism of sunscreen is to absorb or block ultraviolet rays through organic or inorganic sunscreens to prevent ultraviolet rays from reaching the skin and causing damage. Commonly used organic sunscreens such as sylates, cinnamates, anthranilates, etc., these substances have a strong ultraviolet absorption function. Inorganic sunscreens are mainly titanium dioxide and zinc oxide. These two inorganic substances exist in the coati...
