Description

Multifunctional color sun screen and its preparation method

Technical Field

The invention relates to the technical field of daily cosmetics, in particular to a multifunctional colored sun cream which integrates coloring and sun screening and has the effects of whitening, resisting bacteria, diminishing inflammation, resisting oxidation and resisting ultraviolet and a preparation method thereof.

Background

The sun screen is one of important skin care products for daily skin protection, and mainly plays a role in preventing sunlight and relieving irritation of adverse factors to the skin. Sunscreens commonly used in sun-screen creams fall into two categories, organic sunscreens and physical sunscreens. The organic sunscreen agent absorbs ultraviolet rays and then releases the ultraviolet rays in a lower energy form, so that direct damage of the ultraviolet rays is avoided, and the organic sunscreen agent is usually some aromatic compounds which are harmful to human bodies after long-term use; the physical sun-screening agent mainly comprises inorganic powder titanium dioxide and zinc oxide, mainly blocks ultraviolet rays by refraction, is harmless to human bodies, but has the problems of dry skin, oil production, pore blockage, difficult absorption, poor air permeability and the like easily caused by long-term use due to high surface energy and poor compatibility with the skin.

The color sun screen cream not only can isolate and prevent sunlight, but also has the effects of concealing and adjusting skin color, and is similar to foundation. Therefore, in recent years, the beauty lovers have attracted much attention, and the colors of the sun screen can be roughly classified into six categories, namely near-skin color, purple color, white color, blue color and golden color, and the effects of skin color modification by different colors are different. The common colorant in the color sun screen cream is an inorganic pigment, has the advantages of sun resistance, heat resistance, good solvent resistance and strong covering power, but has low tinting strength, poor color vividness, large toxicity of partial metal salt or oxide and poor compatibility with skin, and has the problems of safety, skin dryness, pore blockage, oil production and the like after long-term use.

Therefore, the development and research of a safe and healthy color multifunctional sun screen capable of fundamentally improving skin problems are urgently needed.
