Abstract

The invention discloses a galangal and tsaoko amomum fruit sunscreen emulsion. The sunscreen emulsion is prepared from the following raw materials in percentage by weight: 6%-8% of liquid oil, 3%-4% of solid oil, 2%-3.5% of a fat-soluble and/or water-soluble natural emulsifier, 3%-4% of a humectant, 2%-3% of a fat-soluble and/or water-soluble additive, 0.05%-0.12% of a chelating agent, 1%-2% of anatural antioxidant, 0.6%-1.2% of a fat-soluble and/or water-soluble natural preservative, 2%-5% of galangal essential oil and 1%-3% of tsaoko amomum fruit essential oil, and the balance being deionized water. According to the invention, galangal essential oil and tsaoko amomum fruit essential oil, which are extracted from natural medicinal fragrant plants and have sun-screening components are applied to the sun-screening emulsion, so that the green, natural and non-irritant sun-screening emulsion with the effects of whitening, moistening, sun-screening, repairing, diminishing inflammation, resisting bacteria, resisting oxidation and the like is prepared.

Description

technical field [0001] The invention relates to the technical field of cosmetics, and more specifically relates to a galanga galanga sunscreen emulsion and a preparation method thereof. Background technique [0002] Ultraviolet rays (UVC segment) with a wavelength of 200-280nm in sunlight can only penetrate the stratum corneum of the skin, and will not cause harm to human skin. The human body can be sterilized and sterilized, and vitamin D can be produced in the skin, which is beneficial to health. Ultraviolet rays with a wavelength of 290-320nm (UVB segment, also known as the red segment) can transmit to the epidermis of the skin and can make the skin red. This is the main band for people to prevent sunburn; ultraviolet rays with a wavelength of 320-400nm ( The UVA section, also known as the tanning section), can reach the dermis and make the skin tanned. In short, the harmful ultraviolet rays in the sun can make the dermis gradually harden, dry the skin, lose its elastici...
