Description

[Technical field]

[0001] The present invention relates to an oil-gelling agent and a cosmetic preparation containing the oil-gelling agent. [Background technology]

[0002] Oil gelling agents capable of gelling hydrophobic oils and silicone oils are widely used as materials for cosmetics and the like due to their ability to solidify oils. Well-known examples of such gelling agents include hydrocarbon polymers such as polyethylene wax, long-chain fatty acids, and long-chain alcohols. In addition, as an oil gelling agent with a distinctive structure that is often used in cosmetics, a sugar skeleton-based agent in which some of the hydroxyl groups have been acylated is known (Patent Document 1).

[0003] Many of these oil gelling agents use hydrophobic interactions and hydrogen bonds (or dipole-dipole interactions) to form a gel. Therefore, gelling agents with strong hydrophobic interactions may have difficulty gelling hydrophobic oils, and conversely, gelling agents with strong hydrogen bonding properties may have difficulty gelling oils with hydrogen bonding properties. In light of this, there is a demand for gelling agents that can gel a variety of oils.

[0004] A gelling agent based on an acrylic polymer is known that allows adjustment of hydrophobicity and hydrogen bonding property by adjusting the ratio of constituent monomers (Patent Document 2). However, there is room for improvement in terms of the diversity of oils that can be gelled. [Prior art documents] [Patent documents]

[0011] [(a) Amphiphilic (meth)acrylic monomer] The (a) amphiphilic (meth)acrylic monomer is a (meth)acrylic monomer represented by the following general formula (1), and may be used alone or in combination of two or more kinds. [ka] (In the formula, R 1 is a hydrogen atom or a methyl group, R 2 is a linear or branched alkyl group having 1 to 21 carbon atoms.

[0016] [(b) Hydrophilic (meth)acrylic monomer] The (b) hydrophilic (meth)acrylic monomer is a hydrophilic (meth)acrylic monomer represented by the following general formula (2). [ka] (In the formula, R 1 is a hydrogen atom or a methyl group, R 3 is a linear or branched alkylene group having 2 to 10 carbon atoms.

[0019] [(c) Silicone macromer] The copolymer of the present invention can have a monomer made of a silicone macromer as a constituent unit. By grafting a silicone chain, the compatibility with silicone oil is improved, and the gelation of the silicone oil becomes more possible.
