Problems solved by technology

Such substances that protect the skin from sunburn by providing a solid physical barrier to reflect and refract ultraviolet rays are collectively referred to as physical sunscreens. Commonly used physical sunscreens include titanium dioxide and zinc oxide sunscreens. Physical sunscreens are irritating and easy to clog Pores and other issues
Organic synthetic substances that absorb ultraviolet energy to a higher energy level and then release excess energy in the form of heat or visible light to play a sunscreen effect are collectively referred to as chemical sunscreens. Chemical sunscreens have poor photostability and are easy to oxidize. Deterioration and cause skin allergies and other problems

Abstract

The invention belongs to the field of skin-care products and particularly relates to a moisture-preservation sunscreen skin whitening composition as well as a preparation method and application thereof. The moisture-preservation sunscreen skin whitening composition is prepared through the following raw material ingredients in parts by weight: 20-40 parts of licorice root, 10-20 parts of peach blossom, 15-30 parts of oriental lizardtail, 16-25 parts of tree peony bark, 6-15 parts of hyacinth bletilla and 8-20 parts of nostoc commune. The preparation method comprises the following steps: extracting effective constituents of licorice root, peach blossom, oriental lizardtail and tree peony bark by virtue of a superfine grinding technology in combination with ultrasonic-assisted extraction; performing low-temperature degreasing on the hyacinth bletilla and nostoc commune, and performing microwave-assisted extraction of polyose; and finally, re-extracting all residues by use of CO2 supercutical fluid, so as to ensure that the effective ingredients of licorice root, peach blossom, oriental lizardtail, tree peony bark, hyacinth bletilla and nostoc commune can be maximally utilized. The moisture-preservation sunscreen skin whitening composition provided by the invention has excellent efficacies of resisting sunlight, whitening skin, preserving moisture, removing speckles, resisting oxidation, and inhibiting bacteria, and is safe and free from stimulation.

Description

technical field [0001] The invention belongs to the field of skin care products, and in particular relates to a moisturizing sunscreen and whitening composition as well as a preparation method and application thereof. Background technique [0002] In recent years, a large amount of fluoride gas represented by Freon has been emitted, and the atmospheric ozone layer has been irreversibly damaged, thereby weakening the ozone layer's ability to filter and block ultraviolet rays. Scientific studies have shown that the destruction of the ozone layer is one of the main reasons for the rising incidence of human skin cancer. Because ultraviolet radiation will change the structure and function of cell components, when the cells are saturated with ultraviolet radiation, the cells will lose the ability to communicate with other cells and undergo apoptosis. Therefore, protecting the skin against ultraviolet radiation is an effective measure to prevent skin cancer. The ultraviolet radia...
