Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a detergent composition, more specifically, a detergent composition containing an anionic or amphoteric surfactant and a branched quaternary ammonium salt, which improves suppleness, smoothness, and dryness of hair after washing. A shampoo that has an extremely excellent conditioning effect that makes it easy to manage the hair, suppresses stickiness, and is easy to comb and run with your fingers. The present invention relates to a detergent composition suitable for a liquid detergent that has a good texture after washing. [Prior art] A detergent containing a cationic polymer such as cationic cellulose or a cationic activator for the purpose of imparting a conditioning effect to washed hair or improving the texture of clothes after washing. Many compositions are currently commercially available. These detergents are generally excellent in making hair and clothes softer after washing. [Problems to be Solved by the Invention] However, since these detergents are used in combination with cationic polymers and cationic activators, they have the drawbacks of reduced cleaning performance and insufficient texture on clothes and hair after drying. had. That is,
In laundry detergents, the soil cleaning power is reduced due to the influence of cationic activators, and when used in combination without impairing the detergency, the softness and texture of the finished clothes may not be sufficient. In addition, in shampoo, the process of drying the hair causes stickiness,
The conditioning effect was insufficient, such as difficulty in combing the hair, and as the hair dried, the complex of the surfactant and cationic polymer solidified, causing fried hair and stiffness. Furthermore, when the amount of cationic polymer added is increased to compensate for these drawbacks, there is a problem in that the stickiness increases and the texture of the hair is impaired. For this reason, there has been a desire for a detergent with a high conditioning effect that imparts suppleness and softness to clothes and hair after washing and drying, and provides an excellent finished texture. [Means for Solving the Problems] In order to solve the above-mentioned drawbacks, the present inventors conducted extensive research and found that a detergent composition containing a branched quaternary ammonium salt in an anionic or amphoteric surfactant has been developed. , the texture of clothes after washing is good, and in shampooing, there is no stickiness during the drying process or stiffness of the hair after drying, which are the disadvantages of shampoo compositions containing cationic polymers, leaving the hair supple and smooth.
