Problems solved by technology

[0003] The sunscreen agents added in sunscreen cosmetics can be roughly divided into two categories: one is inorganic sunscreen agents such as nano-titanium dioxide and zinc oxide, which have the ability to scatter and absorb ultraviolet rays, but it is difficult to achieve high sunscreen effect and good use when used alone Effect
The other type is organic sunscreens, such as esters of p-aminobenzoic acid and its derivatives, cinnamate, salicylate, benzophenone and its derivatives, etc. These sunscreens are often transparent Light substances can absorb ultraviolet rays, but most of them have side effects such as skin allergies and affecting skin metabolism

Abstract

The invention provides an inorganic sunproof nano emulsion containing Abelmoschus manihot L. medic and its preparing process, wherein the emulsion is a oil-in-water type emulsion system prepared from extract of Abelmoschus manihot L. medic, refined konjaku flour, nano titanium oxide, nano zinc oxide and related adjuvant.

Description

technical field [0001] The invention relates to cosmetics, in particular to a sunscreen lotion containing hollyhock and a preparation method thereof. Background technique [0002] Ultraviolet rays in sunlight can be divided according to their wavelengths: long-wave ultraviolet rays with a wavelength of 320-400nm, called A-type ultraviolet rays (UVA); medium-wave ultraviolet rays with a wavelength of 290-320nm, called B-type ultraviolet rays (UVB) and Short-wave ultraviolet rays with a wavelength of 200-290nm are called type C ultraviolet rays (UVC). Because the wavelength of ultraviolet rays is very short and the energy is quite high, its destructive power is very large. If it is exposed to the body for a long time, it will damage human skin, cause inflammation or sunburn, and even cause skin cancer. UVB is the main cause of skin inflammation and sunburn. Research results in recent years have proved that long-wave UVA, which has been ignored by people for a long time, has ...
