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 its application, belonging to the field of cosmetics. The sunscreen composition of the present invention comprises diisopropyl adipate, ethylhexyl methoxycinnamate and ethylhexyl salicylate, wherein diisopropyl adipate, ethylhexyl methoxycinnamate The weight ratio to ethylhexyl salicylate is diisopropyl adipate: ethylhexyl methoxycinnamate: ethylhexyl salicylate=15‑25:5‑10:2‑5, Not only can the product obtain a relatively high SPF value under the condition that the addition amount of ethylhexyl methoxycinnamate and ethylhexyl salicylate is relatively low, which avoids their harm to the human body, but also makes the methoxy Ethylhexyl cinnamate and ethylhexyl salicylate can be completely dissolved in diisopropyl adipate, avoiding the instability of the product due to the crystallization of sunscreen; use it together with refreshing oil emollient, A refreshing, stable primer with good sun protection effect and easy industrial production 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...
