preparation example Construction

[0039] The preferred preparation condition is that after umbilical laver seaweed is ground for 30 minutes, take an appropriate amount of treated seaweed and put it into a 100 liter soaking tank and add propylene glycol aqueous solution, wherein the material-liquid ratio of seaweed and propylene glycol aqueous solution is 1:20, and the water in the propylene glycol aqueous solution and Propylene glycol mass ratio is 1:2, slow stirring and soaking for 24 hours, extraction time is 10min, extraction temperature is 100°C, and microwave power is 300W. The Umbilical Porphyra extract prepared under this optimal condition has the best sunscreen effect, and the PA value of the test formula increases from 5.6 to 10.5 after adding 10% Umbilical Porphyra extract.

[0040] As one of the natural sunscreen algae components, Dunaliella salina is a kind of halophilic green microalgae. The phytoene and phytoene contained in its extract have unique characteristics of absorbing ultraviolet rays, an...

Abstract

The invention discloses a sunscreen cosmetic composition and a method for preparing seaweed sunscreen components of the composition. The sunscreen cosmetic composition comprises the following components in percentage by weight based on the total weight of the composition: 0.01-10 percent of a porphyra umbilicalis extract, preferably 5 percent, 0.01-10 percent of a dunaliella salina extract, preferably 5 percent, 0.0001-1 percent of a haematococcus pluvialis extract, preferably 0.001 percent, 0.01-10 percent of seawater pearl powder, preferably 1 percent, and 0.01-10 percent of codium tomentosum extract, preferably 10 percent. According to the composition disclosed by the invention, the irritation and allergic reactions of organic sun-screening agents brought to the human body can be effectively reduced, the injured skin can be repaired during sun protection, and water is replenished to the skin. According to the preparation method disclosed by the invention, a wetting agent propylene glycol for cosmetics serves as an extraction solvent, the porphyra umbilicalis extract, dunaliella salina extract and haematococcus pluvialis extract are obtained under specific preparation conditions, and hazards of organic solvents for conventional extraction are avoided.

Description

technical field [0001] The invention relates to a sunscreen cosmetic composition and a preparation method of seaweed sunscreen components thereof. The invention belongs to the field of personal care, in particular to a preparation method of a seaweed component with a significant sunscreen effect and the application of the combination in sunscreen cosmetics. Background technique [0002] Ultraviolet rays are the main research focus of photoaging at this stage. Ultraviolet rays are divided into three bands UVA, UVB, and UVC. Among them, UVC is almost completely absorbed by the ozone layer and cannot reach the surface of the earth. UVB is ultraviolet rays with a wavelength of 280-320nm. Most of UVB is absorbed by the epidermis of the skin and will not cause changes in the DNA of keratinocytes. However, because of its high energy, it will cause strong photodamage to the skin and even cause skin cancer. The SPF (Sun Protection Factor) value is usually used to evaluate the UVB ...
