Abstract
An emulsified composition for hair, which contains a nonionic surfactant that is a solid at normal temperature and has a Krafft point of at least 40° C., an oil component, and water, and which has an average emulsified particle size of 0.5 μm or less, provides long-lasting luster. Further, an emulsified composition for hair, which is an water-in-oil emulsified composition and which contains the following two types of oil phase as the oil phase, improves the feel of hair immediately after use: 1) an oil phase with an average particle size of 0.5 μm or less, formed with a nonionic surfactant that is a solid at normal temperature and has a Krafft point of at least 40° C., and 2) an oil phase with an average particle size of 0.5 to 100 μm, formed with a surfactant and/or an alkyl-modified carboxyvinyl polymer.
