AI Technical Summary
Technical Problem
Existing solid cosmetics are difficult to solidify while the moisturizer is dissolved, and they cannot dissolve and solidify oils with occlusive effects, making it difficult to achieve both moisturizing and occlusive effects.
Method used
A homogeneous mixture of oil-based and water-based liquid media is used, and water-based and oil-based curing agents are used to gel or cure it, ensuring that the ratio of oil-based to water-based liquid media is between 0.1 and 0.9, and an appropriate amount of oil-absorbing powder is added.
Benefits of technology
It achieves uniform compatibility between the oil and water phases, maintains the sealing effect of the humectant during the curing process, and provides diverse physical properties.

Abstract
The present invention provides a composition which is solidified by using a curing agent dissolved in the one-phase liquid composition after the oil phase having a sealing effect is made compatible with a humectant with a desired moisturizing effect. A solid composition, characterized in that it comprises: an oily liquid medium that separates when mixed with water at a 1:1 ratio; an aqueous liquid medium, said aqueous liquid medium being an organic liquid medium other than water, which forms a homogeneous phase when mixed with water at a 1:1 ratio and also forms a homogeneous phase when mixed with said oily liquid medium; an aqueous curing agent soluble in said aqueous liquid medium and gelling and / or curing said aqueous liquid medium, and / or an oily curing agent soluble in said oily liquid medium and gelling and / or curing said oily liquid medium, said oily liquid medium and aqueous liquid medium being gelled and / or cured by the aqueous curing agent and / or oily curing agent, wherein the total amount of said aqueous liquid medium, oily liquid medium, aqueous curing agent and oily curing agent is more than 90% by mass of the composition excluding powder.
