| description | The present invention relates to a cosmetic in which the ultraviolet protection effects are increased by heat, and a method for manufacture thereof. The manufacturing method of the present invention includes(1) a step of preparing a sample composition containing (A) an ultraviolet protectant and (B) one or more humectants that have an IOB of 5.0 or lower and that are selected from among alkylene oxide derivatives and polyhydric alcohols; and(2) a step of selecting a sample composition in which ultraviolet protection effects are increased after heat treatment in comparison to before heat treatment, in accordance with an evaluation method including the following steps (i) to (iv):(i) a step of forming a coating film of the sample composition on a substrate,(ii) a step of heat-treating the coating film of the sample composition,(iii) a step of measuring ultraviolet protection effects of the coating film of the sample composition that has not been heat-treated and of the coating film of the sample composition that has been heat-treated, and(iv) a step of comparing the measured ultraviolet protection effects. |
