Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an aerosol shampoo composition, and more specifically,
The present invention relates to an aerosol shampoo composition which has low irritation, is easy to use, has good foam retention and foam slip, and has excellent rinsability.

[Conventional technology and its problems]

A shampoo, especially a baby shampoo, is required to have low irritation to the skin and eyes and be easy to handle.

Currently, most of baby shampoos on the market are liquids and are filled in bottles such as plastics. For this reason, it is necessary to open and close the lid with both hands when using, or The disadvantage is that a container with a special lid that can be operated with one hand must be used.

On the other hand, since the undiluted solution is directly applied to the scalp with low hair density, skin irritation is a problem. As a solution to this problem, so-called imidazoline-based amphoteric surfactants, ethylene oxide-added sulfosuccinate-based surfactants, etc. are used in infant shampoos. However, although these surfactants are less irritating than the alkyl sulfates, alkyl ether sulfates, etc., which are frequently used for adults, they are inferior in foaming and cleaning performance, and as a stock solution. It cannot be said that there is no concern about irritation when used, and further improvement has been desired.

Absent. Further, even if the amount of the surface-active component is less than that, the foaming performance immediately after injection is improved, but the foam persistence (foam retention) is not good.

However, since the aerosol shampoo composition of the present invention contains a relatively low concentration of a specific surfactant and a relatively large amount of a specific water-soluble polymer, the durability of foam when used as an aerosol is improved. Not only is it improved,
Good foam slip and excellent rinsability. Further, since the concentration of the surfactant in the undiluted solution is low, there is little concern about skin irritation, and since it can be easily operated with one hand during use, it is particularly preferable for infants.
