Problems solved by technology

At present, sunscreen products on the market are mainly divided into W / O and O / W in terms of dosage forms. W / O is easier to achieve a high index and is waterproof and sweatproof, but most of the water-in-oil systems have greasy, oily skin and poor air permeability.
O / W is relatively refreshing and moisturizing, but oil-in-water products usually have poor water resistance and insufficient water and sweat resistance. If the water resistance is improved by increasing the amount of film-forming agent, the sticky skin feeling brought by the film-forming agent will be reduced. Great loss of freshness
Most of the current sunscreen products contain emulsifiers and film formers, emulsifiers bring potential irritation, and film formers cause sticky feeling

Abstract

The invention discloses a sunproof cosmetic and a preparation method therefor. The sunproof cosmetic comprises the following ingredients in percentage by weight: 5%-10% of humectant, 0.2%-1.5% of thickener, 2%-4% of aqueous sun screener, 17.6%-23% of oily sun screener, 1.8%-5.7% of grease, 1%-2% of preservative, 0.5%-5% of skin conditioner, 2%-4% of pH regulator and the balance of water. Accordingto the sunproof cosmetic and the preparation method therefor, through optimizing a formula of the sunproof cosmetic and the preparation method for the sunproof cosmetic, the prepared sunproof cosmetic is free of a film former, is fresh, cool and not sticky and greasy and has both good water resistance and a high sunproof index; due to no emulsifier, irritation to skin caused by emulsifiers is avoided, and the product safety is greatly improved; and the appearance is novel, transparent gel contains spherical oil droplet capsules which are instantly melted in case of being smeared on the skin and are rapidly spread, and thus, the user experience is good.
