Abstract

The purpose of the present invention is to provide an oil-in-water emulsion composition thickened with a hydrophobically modified polyether urethane, the composition having improved high-temperature stability and giving a pudding-like unique feeling. The invention provides an elastic jelly-like composition characterized in that a hydrophobically modified polyether urethane has been incorporated into an oil-in-water emulsion including oil droplets with an average particle diameter of 150 nm or smaller. The elastic jelly-like composition is transparent or translucent, gives a pudding-like elastic feeling, has excellent viscosity stability at high temperatures, and is suitable for use as a cosmetic-preparation base. The hydrophobically modified polyether urethane is especially preferably a PEG-240 / decyltetradeceth-20 / HDI copolymer.

Description

technical field [0001] The present invention relates to cosmetics with unique tactile sensations. More specifically, it relates to a gel-like oil-in-water emulsified cosmetic having unique elasticity of soft elasticity and excellent high-temperature stability. Background technique [0002] Hydrophobically modified polyether polyurethane (Hydrophobically modified Ethoxylated URethane Copolymer: HEUR) is also blended in cosmetic compositions and the like as a water-soluble thickener excellent in viscosity stability and usability (see, for example, Patent Document 1). Compositions thickened with hydrophobically modified polyether polyurethane give a unique soft and elastic feel, making them attractive as cosmetic bases for applying to the skin, etc. [0003] However, although this composition has the characteristic that the viscosity does not easily change due to changes in the salt concentration mixed together or the pH of the composition, there is a problem that the viscosit...
