Definitions
- the present invention relates to cosmetics comprising polyglyceryl caprylate.
- Surfactants are generally known to form aggregates called micelles, with hydrophilic groups facing outward and hydrophobic groups facing inward, when they reach a certain concentration or higher in an aqueous solution, dissolving transparently and stably. It is The concentration at which micelles are formed varies depending on the properties of the surfactant and solvent, but in general, the lower the concentration, the more difficult it is to form micelles. On the other hand, if the concentration of the surfactant is high, it may cause stickiness during use, impairing the feeling of use. Therefore, for example, Patent Document 1 proposes a cleansing agent containing a polyglycerol fatty acid ester to suppress stickiness.
- Nonionic surfactants present in an aqueous solution become less soluble when the temperature rises, forming micelles and becoming unable to dissolve transparently, making it difficult to maintain the transparency of the liquid. Become.
