Description

[Technical Field]

[0001] The present invention relates to a non-aqueous composition suitable for use as a cosmetic, such as for hair applications, and a hair treatment method using the composition. [Background technology]

[0002] Treatment using a non-aqueous composition suitable as a leave-in treatment can impart a different feel to hair than aqueous treatments. Volatile cyclic silicones such as decamethylcyclopentasiloxane are known as commonly used ingredients in non-aqueous compositions, but due to the increasing global demand for cosmetics, there are concerns about their supply. Under these circumstances, there is a need to reduce the amount of volatile cyclic silicones used.

[0003] Volatile hydrocarbons and volatile acyclic silicones are considered to be candidates for alternative ingredients to volatile cyclic silicones. As an example of a non-aqueous composition containing these candidate alternative ingredients, Patent Document 1 discloses an oily hair cosmetic composition containing a volatile hydrocarbon oil, a vegetable oil, and dimethiconol with a viscosity of 10,000 mPa·s or more and 5,000,000 mPa·s or less at 25°C (see claim 1 of Patent Document 1).

[0005] However, when a non-aqueous composition is exposed to light, the composition may develop or develop turbidity. The development or development of turbidity during product manufacturing or on the market may cause quality concerns among manufacturers and consumers, and therefore, it is desirable to propose a technology to suppress the development or development of turbidity.
