Alcohol-based suntan oil and preparation method thereof

Abstract

The invention discloses an alcohol-based suntan oil and a preparation method thereof. According to percentage by weight, the alcohol-based suntan oil is prepared from 1.0 to 30.0 percent of sunscreen, 1.0 to 10.0 percent of water-repellent agent, 10.0 to 50.0 percent of grease, 1.0 to 20.0 percent of polyol and 10.0 to 87.0 percent of ethanol, wherein the sum of the percentages by weight of all the components of the alcohol-based suntan oil is 100 percent. The invention adopts the ethanol as a carrier for the suntan oil, the preparation process for the sunscreen product is simplified, and by regulating the proportion between the alcohol phase and the oil phase, the prepared non-emulsified suntan oil not only has a high sun protection factor and long-wave ultraviolet protection factor, but also has good waterproofness and excellent sensory experience.

Description

technical field [0001] The invention belongs to the field of cosmetics and relates to an alcohol-based sunscreen oil and a preparation method thereof. Background technique [0002] Ultraviolet rays in sunlight are electromagnetic waves with a wavelength shorter than visible light. The ultraviolet rays absorbed by the skin can cause damage to DNA, resulting in wrinkles, sunburn, cataracts, skin cancer, and even visual damage and immune system damage. According to the different effects of ultraviolet rays on organisms, ultraviolet rays are divided into different bands in medical treatment: the wavelength 320-400nm is the UVA band. The ultraviolet rays in this band have strong penetrating power and can directly reach the dermis of the skin, destroying elastic fibers and Collagen fibers can tan the skin and cause wrinkles; the wavelength 280-320nm is the UVB band, and the ultraviolet rays in this band have erythema effects on the human body. Long-term or excessive exposure will...
