Abstract

PURPOSE:To obtain a detergent composition which is improved in foaming power and detergency and less irritative to skin by adding a specific amount of alkylpolyglyceryl ether as a co-surfactant to alkyl glycoside. CONSTITUTION:A detergent composition is obtained by mixing alkyl glycoside (preferably one represented by formula I, wherein R1 is 8-18C alkyl, alkenyl or alkylphenyl; R2 is 2-4C alkylene; x is 0 to 5; G is a residue derived from a 5-6C reducing sugar; and y is 1.0 to 3.0), and alkyl polyglyceryl ether (preferably one represented by formula II, wherein R3 is 8-18C alkyl, alkenyl or alkylphenyl; GL is a residue derived from glycerine; and z is 2 to 4) in a weight ratio of 100 to 1-50. By the addition of the as a co-surfactant to the alkyl glycoside, it is possible to obtain a detergent composition which hardly makes hands chapped during or after a wash. Detergency (in particular, the effect of preventing oil from causing redeposition) can be improved by adding an ethylene oxide addition-type nonionic surfactant in such an amount as will make the weight ratio of alkyl glycoside, alkyl polyglycery ether and the nonionic surfactant 100:1-50:1-50.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a detergent composition that has excellent foaming power and detergency, and further has low l1iIJ harshness on skin.

l.

[Problem to be solved by the prior art and the invention 3 Hard surface cleaning agents for tableware and the like usually have the main purpose of removing oil and fat stains. When attempting to remove oil and fat stains using such a cleaning agent, the user generally lathers the cleaning agent with his or her hands or a sponge. The function of the foam at this time is to reduce the force required to scrape off the dirt, and in many cases, the foaming power of the cleaning agent is a measure of its ability to clean grease stains. is an important factor for such cleaning agents. Therefore, detergents with excellent ability to remove oil and fat stains and foaming power have been widely used in the past. An example of this is an alkylbenzene sulfonate as the main surfactant;
α-olefin sulfonate, alkyl sulfate,
Examples include those using anionic surfactants such as paraffin sulfonate and ethoxylated alkyl ether sulfate 1, among which sodium alkylbenzene sulfonate is widely used as a base with excellent cleaning performance. Ta. However, products using these anionic surfactants have a strong degreasing power from the skin and have the disadvantage of easily causing rough hands.Therefore, recently, polyoxyethylene alkyl ether sulfate, which is less irritating to the skin, has been developed. By using ester salt as the main cleaning base and using tertiary amine oxide, higher fatty acid jetanolamide, etc. as auxiliary surfactants, various properties are further improved and the effect on the skin is made milder. Cleaning agents are used.

However, although the effects of various detergents on the skin have become milder than in the past, they still have not yet reached a fully satisfactory level.

On the other hand, alkyl glycosides, which are sugar derivative surfactants, are mild surfactants and even though they are nonionic surfactants, they not only generate stable foam by themselves, but also have other negative effects. It is known that it acts as a foam stabilizer for ionic surfactants, and has been attracting attention in recent years. For example, JP-A-58-104625 discloses a foaming surfactant composition containing an alkyl glycoside and an anionic surfactant, and JP-A-62-74999 discloses a foaming surfactant composition containing an alkyl glycoside and an anionic surfactant. Hypoallergenic foaming power containing agent and fatty acid alkanolamide,
Liquid detergent composition for hand-washing dishes with excellent detergency, JP-A-1988-1
No. 8-132094 describes a laundry detergent composition containing an alkyl glycoside, an alkyl glyceryl ether, and a nonionic surfactant and having good detergency. As described above, detergents containing alkyl glycosides as a main ingredient are less irritating to the skin than conventional detergents, and have superior performance such as foaming power, and are therefore viewed as promising.

The first object of the present invention is to provide a detergent composition that provides a better feel to hands during and after washing without impairing these properties of alkyl glycosides. The purpose of this invention is to provide a detergent composition that also has enhanced detergency against oil (oil re-deposition prevention effect).

[Means to solve the problem]

Under these circumstances, the present inventors conducted extensive research to maximize the properties of alkyl glycosides, and found that if alkyl polyglyceryl ether is used as a co-surfactant in a specific ratio, the We have found that a detergent that feels good on the hands can be obtained, and that if an ethylene oxide-added nonionic surfactant is added to this detergent, the detergency (oil re-deposition prevention effect) can be improved.
