AI Technical Summary

Benefits of technology

The composition provides long-lasting moisture, smoothness, and ease of combing, prevents unfavorable touch and stickiness, and maintains these properties through repeated washing and drying, while also improving foaming and washing efficiency.

Problems solved by technology

However, the effects of imparting to hair such properties as luster, smooth touch, and protection against damage obtained with the use of the aforementioned composition do not last long and are lost (or diminished) after brushing or drying.
Furthermore, the aforementioned composition cannot impart to hair a sufficient moist feeling and thick-film touch (here and hereinafter, the feeling that the hair coat is thick and moist).
The moist feeling is lost also when the hair treated with the aforementioned compositions is in a dry or wet state.
However, the aforementioned composition is unable to impart to hair a sufficient feel of smoothness.
Moreover, the positive effects imparted to hair by the composition also cannot last long and are lost (or diminished) after the hair is brushed or dried.
Furthermore, as the aforementioned composition could not form a sufficiently thick coating film on the surface of the hair, it could not provide the thick-film touch.
When hair treated with the aforementioned composition becomes dry, it produces the feel of unfavorable touch and tackiness.
However, the last-mentioned composition produces an unfavorable feeling to the touch when hair is in a wet state and cannot produce good feeling in hair washing.
Furthermore, since this composition cannot form a sufficiently thick coating layer on the surface of hair, it also cannot impart to hair a thick-film touch.

Abstract

(1) The invention provides a composition for hair that imparts to the hair such properties as moist feeling, the feel of smoothness, thick-film touch, and ease of combing. These properties are long lasting and do not disappear after repeated brushing.Furthermore, neither in a moist state during washing, nor in a dry state, the hair produces the feel of unpleasant touch. The hair treated with the composition of the invention does to become sticky after drying. (2) The shampoo compositions of the invention demonstrate superb foamability and washability. The feel of smoothness and ease of combing are not lost even after the repeated hair wash.The composition of the invention comprises a specific block copolymer of polyorganosiloxane and polyoxyalkylene used in the amount of 0.01 to 10 mass %.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a divisional of U.S. Ser.
