Description

  The present invention relates to a hair cleansing agent having excellent usability.

  Hair is exposed not only to friction during shampooing but also to many other causes of damage such as daily brushing, ultraviolet rays and the heat of dryers. Hair damage caused by these causes a feeling of dryness, reduces the gloss of the hair, causes split ends and broken hair, and has developed into a cosmetic problem. Damaged hair has increased surface friction, making it easier for the hairs to be entangled during shampooing and rinsing, leading to further damage and causing a vicious circle.

  In hair cleaners such as shampoos, coexistence of cleanability and conditioning properties is a major issue. In particular, it is an important factor that hairs do not get entangled during shampooing. Suppressing tangling has the effect of facilitating shampooing and preventing hair friction, thereby reducing hair damage. For this reason, in many shampoos, in consideration of damage care, contrivances have been made to enhance conditioning effects such as tangling at the time of shampooing and rinsing, and a smooth feel after drying.

  As conditioning agents, cationic polymers, various oils, silicone compounds, etc. are widely known. However, when these components are added in a large amount, the detergency decreases, and the amount of foam increases, and the hair tangling increases. As a result, the feeling of cleanliness is reduced. Especially for people with little hair or thin hair, the remaining conditioning agent feels sticky and the hairstyle after drying is crushed by the weight of the agent, leading to cosmetic problems. For example, there has been proposed a hair cleanser that uses a sulfate surfactant, an amphoteric surfactant, and a specific branched fatty acid in combination with a distribution of the number of moles of ethylene oxide added within a certain range (Patent Document 1). However, this hair cleanser is excellent in foaming and feel after washing and after drying, but it has not been sufficient in suppressing hair entanglement and non-stickiness.

  On the other hand, if the surfactant, which is a cleaning component, is made to have a high detergency or an increase in its blending amount in order to improve the clean feeling, it causes squeezing during rinsing and damages the hair. In addition, after drying, the hair becomes dry and a smooth feel cannot be obtained. It is common to use hair rinses and hair treatments after shampooing to reduce tangling during hair washing and dryness, but these agents have many oily ingredients and are useful for people with little hair or fine hair. May cause stickiness and cosmetic problems as described above.

  For this reason, there has been a demand for a hair cleaning agent that sufficiently satisfies the suppression of tangling of the hair during shampooing and the smooth finish without stickiness.
