Abstract
Abstract A hair rinse composition having improved rinsing performance and a process specified to prepare the same. The composition according to the invention comprises (A) 0.05 to 0.5 wt % of cationic surface active agent, and (B) a higher alcohol or a glycerine mono fatty acid ester having a melting point not lower than 45 DEG C. The ingredient (B) should be contained in an amount of 3 to 15 times by weight to ingredient (A). The composition is prepared by diluting a highly concentrated emulsified product containing 0.4 to 34 wt % of ingredient (A) and (B) in total with 1 to 20 times by weight to the emulsified product of water.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
119 words
A hair rinse composition which comprises (A) 0.05 to 0.5 wt % of a cationic surface active agent, and (B) a second component selected from the group consisting of a higher alcohol, a glycerine mono fatty acid ester having a melting point not lower than 45° C. and mixtures thereof, said second component being present in said hair rinse in an amount of 3 to 15 times by weight to ingredient (A), and wherein said composition is produced by first forming a highly concentrated emulsified product comprising 0.4 to 34 wt % of ingredients (A) and (B), and thereafter diluting said concentrated product with water in the amount of 1 to 20 times by weight of said concentrated product.
Claim 2
Dependent Claim
119 words
A hair rinse composition which comprises (A) 0.05 to 0.5 wt % of a cationic surface active agent, and (B) a second component selected from the group consisting of a higher alcohol, a glycerine mono fatty acid ester having a melting point not lower than 45° C. and mixtures thereof, said second component being present in said hair rinse in an amount of 3 to 15 times by weight to ingredient (A), and wherein said composition is produced by first forming a highly concentrated emulsified product comprising 0.4 to 34 wt % of ingredients (A) and (B), and thereafter diluting said concentrated product with water in the amount of 1 to 20 times by weight of said concentrated product.
