Description

Sunscreen composition with gel network structure and preparation method thereof

Technical Field

The invention relates to the technical field of cosmetics, in particular to a sunscreen composition with a gel network structure and a preparation method thereof.

Background

Ultraviolet rays not only cause sunburn, but also cause damage to the skin such as cell damage, DNA damage, photoaging, and in the most severe cases, skin cancer. Therefore, protecting the skin from ultraviolet rays and caring the skin after sunburn is a great challenge for daily cosmetics.

The solar ray contains ultraviolet rays in three regions of A-wave ultraviolet ray (UVA, 320-400 nm), B-wave ultraviolet ray (UVB, 280-320 mm), and C-wave ultraviolet ray (UVC, 100-280 nm). Wherein UVC is scattered and absorbed when passing through the ozone layer and cannot reach the ground; most of the UVB is absorbed through the ozone layer, the rest reaches the ground, and the UVA reaches the ground surface less well absorbed by the ozone layer. So that UVA and UVB have an effect on humans. Among them, UVA is a main cause of photoaging, and has the following characteristics: 1) 97% of the ultraviolet light reaching the ground is UVA, although UVA is lower in energy than UVB; 2) Influences can be generated in irrelevant regions, seasons and time of day; 3) The permeability to the skin is strong, and the skin can reach the dermis and deeper; 4) After long-term exposure, skin aging phenomena such as spots, wrinkles, sagging and the like are generated. UVB is the leading cause of sunburn and tanning and has the following characteristics: 1) Shorter wavelength, higher energy, leading to immediate sunburn; 2) Causing the epidermis to be thickened and fallen, and direct DNA damage; 3) The main cause of tanning; the purpose of sunscreen is to protect the skin from the harmful effects of ultraviolet light. The deciding factors influencing the purchase of the sunscreen product by the consumer are as follows: 1) strong protection ability, 2) convenience of use, 3) well-known and trusted brands, 4) natural and organic ingredients, 5) price, 6) skin feel and taste, so a sunscreen product which can meet the requirements of high protection, convenience of use (including smearing and removing), high cost performance and comfortable skin feel of consumers is still urgently to be developed.

The prior sunscreen product, for example, patent CN106176302A discloses a phase inversion sunscreen composition and a preparation method thereof, comprising the following components: 50-70% of water, 3-15% of polyhydric alcohol, 0.03-2% of humectant, 0.1-1% of thickener, 15-35% of organic sunscreen agent, 1-15% of inorganic sunscreen agent, 5-18% of dispersant, 1-6% of film forming agent, 1-6% of skin feel regulator, 0.1-3% of preservative and 1.0-6% of emulsifier. The composition contains ethylhexyl methoxycinnamate, octocrylene, ethylhexyl salicylate, homosalate and combinations thereof, more preferably contains one or more of benzophenone-3, benzophenone-4 and avobenzone, and the composition prepared by the invention through a phase inversion technology and a sticky and oily feeling reducing technology has high sun protection value and high waterproof and sweat resistance effects. Patent CN114404330A discloses a sunscreen composition and a preparation method thereof, comprising an inorganic sunscreen agent, an ultraviolet absorbent, a blue light absorbent, a red light absorbent and an active repairing component; the product has good sun-screening performance, can cover full spectrum, and can comprehensively protect ultraviolet rays, red light and blue light; has good skin-adhering property, fluidity and refreshing degree, does not generate whitening phenomenon, and has waterproof and sweat-proof performance.

In addition, the structure of the existing sunscreen product is mainly water-in-oil type, and the defects of heavy skin feel, high cost and the like exist. In view of such problems, researchers have also developed various sunscreen products with gel network structures, but most products are prone to have problems of roughness caused by uneven dispersion of a physical sunscreen agent, oil production caused by the fact that the gel network structure cannot wrap dispersed oil droplets, greasy skin feel caused by excessive addition of water-soluble polymers with gel network structures, and the like due to reasons of inappropriate selection of water-soluble polymers capable of forming the gel network structures, inappropriate collocation of components, inappropriate surface treatment of the physical sunscreen agent or inappropriate selection of particle size ranges. Therefore, it is necessary to find a composition which can meet the requirements of consumers and overcome the common problems of non-water resistance, uneven dispersion of sunscreen agents, difficult smearing, sticky skin feel and the like of the sunscreen products with gel network structures.
