Oily gel compositions: Asahi Kasei Chemicals Corp. has introduced oily gel compositions.¹⁷ The described inventions contain a high amount of an oily component, a multichain polyhydrophilic compound having two or more long-chain hydrophobic groups and hydrophilic groups, a polyhydroxyl compound having two or more OH groups, a surfactant, water (aqua) and another oily component. A method to produce the oily gel composition and a method for mixing a water-containing composition to form an emulsion also are disclosed. For example, L-lysine hydrochloride was reacted with N-lauroyl-L-glutamic anhydride and neutralized with sodium hydroxide to obtain a multichain polyhydrophilic compound. A formulation containing this material is shown in Formula 3.

Transparent cosmetics: Noevir Co., Ltd. has disclosed transparent aqueous cosmetics containing oil-soluble components.18 This invention also relates to a method for manufacturing storage-stable transparent cosmetics that contain oil soluble components. The oil soluble components, such as perfumes and essential oils, are dissolved in phenoxyethanol and surfactants and water are added to obtain a stable solution. An example is shown in Formula 4.
