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 with 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 acyclic silicones and volatile hydrocarbons 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 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 manufacturers and consumers to feel uneasy about the quality of the product, and therefore, it is desirable to propose a technology for suppressing the development or development of turbidity.

[0006] In view of the above circumstances, an object of the present invention is to provide a non-aqueous composition that is excellent in inhibiting the occurrence or progression of cloudiness, and a hair treatment method using the composition. [Means for solving the problem]

[0007] As a result of intensive research, the present inventors have discovered that turbidity in non-aqueous compositions containing volatile acyclic silicones and / or volatile hydrocarbons occurs or progresses when vegetable oils are also blended in. The present inventors have then discovered that blending a silicone surfactant together with vegetable oils can inhibit the occurrence or progression of turbidity caused by vegetable oils, leading to the completion of the present invention.
