Problems solved by technology

[0003] In order to achieve the ideal sunscreen effect, more sunscreen agents are often added to sunscreen products, but excessive use of sunscreen agents results in lower product safety and greater harm to the skin
Most of the existing sunscreen products have the problems of poor compatibility and easy precipitation of sunscreen agents, resulting in poor stability and prone to sweating on the surface. The existence of this problem limits the amount of sunscreen agents added, resulting in the failure of sunscreen products. Sunscreen effect is not ideal

Abstract

The invention provides a sunscreen composition and application thereof, and belongs to the field of cosmetics. The sunscreen composition is prepared from diisopropyl adipate, ethylhexyl methoxycinnamate and ethylhexyl salicylate, wherein the weight ratio of diisopropyl adipate to ethylhexyl methoxycinnamate to ethylhexyl salicylate is (15-25):(5-10):(2-5), not only can the product obtain a high SPF value on the condition that the additive amount of ethylhexyl methoxycinnamate and ethylhexyl salicylate is low, and damage of ethylhexyl methoxycinnamate and ethylhexyl salicylate to the human bodyis avoided, but also ethylhexyl methoxycinnamate and ethylhexyl salicylate can be completely dissolved into diisopropyl adipate, and the phenomenon that due to the fact that crystals of a sun-screening agent are dissolved out, the product is unstable is avoided; the product is matched with a refreshing grease emollient for use, and a primer potion which is refreshing, stable, good in sunscreen effect and easy to industrially produce can be obtained.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a sunscreen composition and its application. Background technique [0002] Excessive exposure to ultraviolet rays will damage the skin's epidermal cells, accelerate the synthesis of pigments, destroy the skin's moisturizing function, make the skin dry, and damage the elastic fibers in the dermis, causing fine lines on the skin, and even cause skin inflammation, Burns, causes skin cancer. Now people often apply sunscreen products to prevent the damage of ultraviolet rays to the skin. [0003] In order to achieve the ideal sunscreen effect, more sunscreen agents are often added to sunscreen products, but excessive use of sunscreen agents results in lower product safety and greater harm to the skin. Most of the existing sunscreen products have the problems of poor compatibility and easy precipitation of sunscreen agents, resulting in poor stability and prone to sweat...
