Abstract

The invention discloses a preparation method for compound plant whitening sunscreen cream. The method is characterized in that compound essential oil taking propolis, licoflavone, sophora flower essential oil and turmeric essential oil as main ingredients is used as a main ultraviolet ray absorbing raw material. The method comprises the following steps: adding the following components by weight percent in turn: 0.1%-0.2% of Carbomer and 25%-30% of deionized water; adding 38%-45% of compound essential oil, 6%-10% of bee wax, 2%-6% of silk fibroin, 2%-4% of glycerol and 15%-20% of an EM-90 emulgator after dissolving, wherein the sum of the weight percent is 100%; uniformly stirring and mixing; adding triethanolamine for regulating pH to about 7.0; quickly stirring and integrally mixing at 65+ / -3 DEG C; heating to 78+ / -2 DEG C, keeping the constant temperature for 4 hours, cooling to room temperature and placing for one week, thereby acquiring the compound plant whitening sunscreen cream. The sunscreen cream can emit natural fragrance, has the anti-bacteria, skin-moisturizing, whitening and sunscreen effects, has no side effect to human body and is convenient in use; the duration is from 10 hours to 12 hours; the average sunscreen effect is 90% or above.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a preparation method of a compound plant whitening sunscreen, which has good sunscreening, whitening and moisturizing effects on the skin. Background technique [0002] Ultraviolet wavelengths are divided into three sections: UVA, UVB, and UVC. Among them, UVB is the mid-band ultraviolet region with a wavelength range of 280-320nm. It has the strongest effect on the skin and can enter the dermis. burns). UVA is a long-wave ultraviolet region with a wavelength range of 320-400nm, which can pass through the dermis. The effect is slow, long-lasting, and cumulative. Over time, it will cause skin aging and increase the damage of UVB to the skin. UVC is a short-wave ultraviolet region with a wavelength range of 200-280nm, which becomes a sterilizing region. Its penetration ability is weak, and its transmission ability can only reach the stratum corneum of the skin, and will not caus...
