Problems solved by technology

[0004] At present, most of the high-multiplier sunscreens on the market are water-in-oil systems or cream systems. Most of the water-in-oil systems feel greasy, oily, and poor in air permeability, while cream systems are relatively sticky and poor in waterproof and sweat resistance.

Abstract

The invention discloses multidirectional protective sun-block water emulsion. The multidirectional protective sun-block water emulsion is prepared from a component A, a component B, a component C anda component D. A preparation method comprises the steps that (1) the component A is put into an oil-phase pot, stirred and heated to 80-85 DEG C, and after complete dissolving, a homogenous body is formed homogenously; (2) the component B is put into a water-phase pot, stirred and heated to 80-85 DEG C, and a jelly-like network suspending substrate is formed homogenously; (3) materials in the oil-phase pot are sucked into the water-phase pot, the temperature is kept at 80-85 DEG C, homogenizing is conducted for 1-3 min, and after heat preservation is conducted for 10 min, stirring and coolingare conducted; (4) when the temperature is decreased to 60 DEG C, the component C is added; (5) when the temperature is decreased to 45 DEG C, the component D is added; and (6) when the temperature isdecreased to 40 DEG C or below, detection and discharging are conducted. The sun-block water emulsion is light in texture, moisturized, easy to absorb, high in high sun-block index, waterproof and resistant to sweat and friction, the damage of ultraviolet rays to skin can be effectively blocked, skin inflammation caused by sunburn is relieved, the moisture degree of the skin can be further maintained, the damaged skin is repaired, and the protective ability of the skin is comprehensively improved.

Description

technical field [0001] The invention relates to a multi-dimensional protective sunscreen water curd and a preparation method thereof, belonging to the technical field of cosmetics. Background technique [0002] The skin is the first line of defense for human health, and it is also the first embodiment of a beautiful appearance. Having a healthy, fair and elastic skin is the goal that everyone pursues. When the skin is exposed to excessive ultraviolet rays, it will damage the epidermal cells; activate tyrosinase, accelerate pigment synthesis, destroy the skin's moisturizing function, make the skin dry, damage the elastic fibers in the dermis, and cause fine lines. Under strong exposure, it can also cause skin inflammation, burns and other damage. When there are abnormalities, it will become pigmented skin cancer, etc. Therefore, sun protection is not only to prevent darkening, but also to delay aging, pigmentation, and resist DNA damage and cuticle damage caused by ultravio...
