Description: SPECIFICATION DETERGENT COMPOSITIONS Technical Field This invention relates to a detergent composi¬ tion, which exhibits a high detergency, good foaming properties, and low irritating properties. This inven¬ tion particularly relates to a detergent composition, which can be stably formulated with a cationic condi¬ tioning agent, and which has markedly high rinsing effects and high conditioning effects when it is used for washing hair. Background Art Most conventional detergents, particularly hair detergents, contain anionic surface active agents as predominant components since such detergents exhibit a high detergency and good foaming properties. However, the anionic surface active agents has high irritating properties. Therefore, when the anionic surface active agents are formulated in hair detergents, the anionic surface active agents are often used in combination with low-irritating surface active agents. There has been a demand for a hair detergent having lower irri¬ tating properties. Also, recently, various attempts have been made in order to obtain a detergent, which also has conditioning effects. As the substances having the conditioning effects, many cationic substances have heretofore been known. However, in cases where a cationic substance is formulated with a detergent, which contains an anionic surface active agent as the predominant component, a complex of the cationic sub¬ stance and the anionic surface active agent is formed undesirably. Therefore, it is difficult to formulate the cationic substance with the detergent, which con¬ tains an anionic surface active agent as a predominant component, and the problems occur in that, for example, sufficient conditioning effects cannot be obtained. Therefore, attempts have heretofore been made in order to obtain a detergent containing, as the predominant component, a nonionic surface active agent, which has lower irritating properties than an anionic surface active agent and can be easily formulated with a cationic conditioning agent. For example, as a detergent containing an alkyl saccharide as a nonionic surface active agent, a low-irritating detergent compo¬ sition, which contains an alkyl saccharide-based non¬ ionic surface active agent and a cationic polymer, has been proposed in, for example, Japanese Patent Publica¬ tion 6-23085. Also, a detergent composition, which contains alkyl saccharide type nonionic surface active agent, a sucrose fatty acid ester, and an anionic surface active agent, or an amphoteric surface active agent, has been proposed in, for example, Japanese Patent Publication 6-23086. However, the alkyl saccharide type nonionic surface active agent is comparatively expensive. Therefore, attempts have also been made in order to formulate a polyoxyethylene alkyl ether type nonionic surface active agent, which is comparatively cheap, with a detergent. However, in general, the polyox¬ yethylene alkyl ether type nonionic surface active agent has poor foaming properties and has been rarely used for hair detergents. Only a shampoo composition, which contains an amide-amine type amphoteric surface active agent or an alkylolamide type nonionic surface active agent as the predominant component and contains a polyoxyethylene type surface active agent as an auxiliary component, has been proposed in, for example, Japanese Patent Application 55-25436. Disclosure of the Invention It is therefore an object of the present inven¬ tion to provide a detergent composition, which exhibits a high detergency, good foaming properties, and low irritating properties, and which can be stably formu¬ lated with a cationic conditioning agent. In view of the above circumstances, the inven¬ tors eagerly carried out research and found that a detergent composition, which exhibits a high detergen¬ cy, good foaming properties, and low irritating proper¬ ties, can be obtained by employing a specific polyox¬ yethylene alkyl ether type nonionic surface active agent, a betaine type surface active agent, and a specific nonionic surface active agent in combination with one another in a specific ratio.

Fair: From 70% to less than 80% of the panel members evaluated the detergency as good. Poor: Less than 70% of the panel members evalu¬ ated the detergency as good. Foaming properties: Into a cylinder was introduced 800 ml of aqueous solution of the shampoo diluted in twenty times amount of water (solution temperature 20 * C) , followed by rotation of a stirring blade equipped within the aqueous solution for 5 minutes. Thereaft¬ er, the aqueous solution was allowed to stand for 30 seconds, and the degree of foaming was evaluated ac¬ cording to the following scale. The rotation rate of the stirring blade was 1,000 rpm, and the rotation was reversed every five seconds. Excellent: Markedly abundant foaming was observed. Good: Abundant foaming was observed. Fair: Foaming was observed, but insufficient. Poor: Almost no foaming was observed. Skin irritation: A conduct of immersing the hands in each shampoo liquid for five minutes and thereafter drying the hands was repeated 10 times by 20 special¬ ized panel members. The degree of irritation to the skin was evaluated according to the following scale. Excellent: 90% or more of the panel members felt that skin irritation was low. Good: From 80% to less than 90% of the panel members felt that skin irritation was low. Fair: From 70% to less than 80% of the panel member felt that the skin irritation was low.

Excellent: Very soft and flexible Good: Soft Fair: Slightly insufficient to softness Poor: Stiffy Stability of detergent: After preparation of the shampoo, the shampoo was shaken violently, followed by allowing to stand at 20 * C for one week, and then the state of the liquid was observed with naked eyes and evaluated according to the scale. Good: Uniformly liquefied. Fair: Almost uniformly liquefied with a little precipitates observed. Poor: A large quantities precipitates were observed.
