AI Technical Summary

Problems solved by technology

Oil-in-water cosmetics are more prone to loss of UV protection agents due to poor water resistance, thereby reducing the UV protection function of sunscreen products
In the research and development of oil-in-water emulsified cosmetics, most of them focus on improving water resistance, and there are few studies on improving water resistance and SPF at the same time

Abstract

The invention belongs to the field of cosmetics, and particularly relates to an oil-in-water sunscreen lotion and a preparation method thereof. The oil-in-water sunscreen lotion is prepared from the following components in parts by weight: 45-60 parts of a group A water phase component, 35-45 parts of a group B oil phase component, 0.5-0.8 part of a group C component, 0.5-1.5 parts of a group D component and 15-20 parts of a group E component; the group B oil phase component is selected from one or more of an organic sunscreen agent, grease, a skin feeling regulator, an emulsifier and an antioxidant; and the emulsifier comprises an O/W type emulsifier with the pH value of 5.5-7.5 and an O/W non-ionic emulsifier with the HLB value of 10-13, and the aqueous solution of the O/W type emulsifier is 5wt%. The oil-in-water sunscreen lotion has the advantages of strong sunscreen capability, no irritation to human bodies, excellent compatibility with silicone oil substances, difficulty in crystallization and precipitation, easiness in film formation, safety in use, good touch and refreshing skin feeling.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to an oil-in-water sunscreen and a preparation method thereof. Background technique [0002] Sunlight is a recognized cause of photodamage, photoaging, and skin cancer. Sunlight consists of ultraviolet (UV) (290-400nm), visible light (400-700nm) and infrared light (>700nm), of which 5% reach the Earth's surface For ultraviolet radiation, a smaller proportion penetrates the atmosphere and reaches the human skin. The effects of UV rays on the skin include erythema, sunburn, drug-induced phototoxicity, photoaging, and non-melanoma skin cancer, among others. In recent years, air pollution, especially the thinning of the ozone layer and the hole in the atmosphere will cause more damage to the skin caused by ultraviolet rays. Therefore, we need to use sunscreen products to protect our skin. [0003] For emulsified sunscreen products, it can be roughly divided into two types of e...
