Abstract

The invention discloses sunscreen cream prepared from rabbit fur protein as a main raw material. The sunscreen cream comprises, by mass, 78.5 parts of distilled water, 1.8 parts of triethanolamine, 0.2 parts of methyl paraben, 7 parts of a rabbit fur protein, 12 parts of monoglycerin stearate, 0.4 parts of dodecanol and 0.1 parts of propylparaben. The invention also discloses a preparation methodof the sunscreen cream. The preparation method comprises heating to melt two oily materials of dodecanol and monoglycerin stearate and rabbit fur protein powder in a water bath at 70 DEG C in a beaker, carrying out thermal insulation, adding an alkaline material triethanolamine into a beaker, dissolving the alkaline material triethanolamine through distilled water, carrying out heating, keeping the temperature of 70 DEG C, carrying out stirring, slowly adding the triethanolamine solution into the blended raw materials along with stirring until complete neutralization and emulsification, stopping stirring after the thick paste-like cream is obtained, carrying out cooling to 45 DEG C and carrying out uniform stirring to obtain a finished product.

Description

technical field [0001] The invention belongs to the technical field of daily chemicals, and in particular relates to the preparation of a sunscreen with rabbit hair protein as the main raw material. Background technique [0002] Due to the accelerated industrialization process, global carbon dioxide emissions have increased sharply, the ozone layer in the atmosphere has become thinner day by day, and the destruction of the ozone layer has reduced the barrier effect on solar radiation, causing actinic skin diseases to increase. Long-term scientific research has proved that ultraviolet rays can change the structure or function of individual cell components, and the radiation of a large amount of ultraviolet rays to cells can cause the cells to lose their ability to communicate with surrounding cells or to die together. Ultraviolet light can be divided into three parts according to the wavelength: UVA area: 320-400nm; UVB area: 280-320nm; UVC area: 200-280nm. Studies have show...
