Problems solved by technology

The release of this heat increases the temperature of the coating, which can bring two results. One is that the human skin feels uncomfortable and has a hot feeling; moreover, the accumulation of heat may lead to thermal decomposition of organic UV absorbers, especially It is an organic compound with a conjugated structure that will thermally decompose under the action of heat

Abstract

The present invention discloses a cooling sun block and a moisturizer and a preparation method thereof. A heat storage compound component is added into the traditional sun block or moisturizer to effectively slow down the heating rate of the sun block or moisturizer coating. The heat storage compound is composed of a phase change material with a linear structure and with a melting point of 20-38 DEG C and cyclodextrin. The phase change material and the cyclodextrin are automatically assembled to form a combined amphiphilic structure; and the phase change material is wrapped in the combined amphiphilic structure to form a stable water dispersion and heat storage compound. The heat storage compound component is added into the traditional sun block or moisturizer, and when the temperature is increased to more than or equal to the melting point, the phase change material in the heat storage compound is melted and absorbs heat, which causes the coating temperature to rise slowly, so that the skin feels comfortable.

Description

technical field [0001] The invention belongs to the field of daily-use chemicals, relates to a skin care product, in particular to a formula and a preparation method of a refreshing sunscreen or moisturizer. Background technique [0002] With the development of the economy and the improvement of people's living standards, leisure, tourism and vacation have become new ways of life and consumption. While enjoying beach, sunshine, outdoor hiking and other activities, people pay more and more attention to the protection of their bodies. The harm of ultraviolet rays to the human body is well known. In order to prevent the harm of ultraviolet rays, the use of sunscreen is becoming more and more extensive. The mechanism of sunscreen is to absorb or block ultraviolet rays through organic or inorganic sunscreens to prevent ultraviolet rays from reaching the skin and causing damage. Commonly used organic sunscreens such as sylates, cinnamates, anthranilates, etc., these substances h...
