JPH10182366A - Shampoo composition for hair - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a shampoo composition for hair with low viscosity, excellent in foaming and detergent properties and further excellent in fragrance by including a prescribed weight ratio of an anionic surfactant and a nonionic surfactant. SOLUTION: This composition includes (A) >=30wt.% anionic surfactant, (B) >=0.5wt.% nonionic surfactant and (C) water as active ingredients. The weight ratio of components B/A is 0.01-0.6, and that of components C/B is 1.5-100. An excellent fragrance is obtained by including 0.01-80wt.% flavor compound having aldehyde group in spite of a concentrated surfactant system. The composition has a low viscosity of 100-3000cp at 30 deg.C while keeping the high foaming and detergent properties without formulating a viscosity-lowering agent such as polyethylene glycol which spoils the foaming properties, in spite of having high concentration of the surfactants.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cleansing composition, and more particularly to a hair cleansing composition containing a surfactant at a high concentration without impairing foaming or detergency and requiring a small amount of use.
Further, the present invention relates to a hair cleansing composition which is excellent in fragrance.

[0002]

2. Description of the Related Art Generally, surfactants used in hair cleansing agents such as shampoos are required to have high foaming properties and high detergency. Conventionally, an anionic surfactant excellent in foaming property and detergency, such as an alkyl sulfate ester salt and a polyoxyethylene alkyl ether sulfate salt, has been blended into a hair cleaning agent.

[0003] In recent years, however, as the awareness of hair damage has increased and a large amount of polymers, silicones, and the like having a conditioning effect have been incorporated into hair cleansing agents, their foaming properties and detergency have been reduced. I have.
Therefore, attempts have been made to increase the compounding concentration of the anionic surfactants having excellent foaming properties and detergency. However, these anionic surfactants have a remarkable increase in viscosity as the concentration increases, and their use as detergents has increased. Will be impaired.
For this reason, conventionally, it was dealt with by adding a thickener such as polyethylene glycol, but in this method, as the concentration of the surfactant is increased, more thinner is required, so that foaming is impaired, The effect obtained by using the concentrated solution was not sufficiently obtained.

[0004] In addition, when the concentration of the surfactant is increased, there is a problem that the fragrance of the fragrance component blended at the same time is suppressed, and it is difficult to obtain a sufficient fragrance.

[0005]

Accordingly, the present invention provides a low-viscosity, high-foaming and detergency compounded with a high-concentration surfactant, and an excellent fragrance with a fragrance component. It is an object to provide the resulting hair cleansing composition.

[0006]

Under these circumstances, the present inventors have made intensive studies and as a result, it has been found that the combination of an anionic surfactant and a nonionic surfactant in a constant weight ratio causes a remarkable thickening. Without increasing the concentration of the surfactant, low viscosity, excellent foaming properties and detergency, and the use of a concentrated hair cleansing composition which requires only half the amount of the conventional one. When a fragrance component is blended, it has been found that a concentrated detergent composition for hair with excellent aroma that is not present in conventional concentrated detergents can be obtained,
The present invention has been completed.

That is, the present invention provides the following components (A), (B) and
(C) (A) 30% by weight or more of anionic surfactant (B) 0.5% by weight or more of nonionic surfactant (C) Water is added to (B) / (A) = 0.01-0.6, (C) / (B) = 1.5 to 100 by weight.
