BACKGROUND OF THE INVENTION
The present invention relates to a cleaning composition, and more particularly to a cleaning composition suitable for a food tableware cleaning agent, a body cleaning agent, and an oral cleaning agent.
[0002]
[Prior art]
Use tableware, cooking utensils, baby bottles, food dishwashing detergents to clean foods and vegetables, etc., detergent compositions used in contact with human skin, such as hair shampoos, body shampoos, facial cleansers, etc. Rinsing is sufficient, but if the cleaning agent is incomplete or well rinsed, it may enter the human body if the cleaning agent remains on the skin, tableware, etc. Remains. For this reason, it is desirable that the safety of the cleaning agent used is high, and there is a demand for a cleaning agent composed of food additives.
[0003]
As such a detergent, JP-A-60-120800 describes a detergent composition in which polyglycerin monolaurate and sucrose laurate are used in combination (weight ratio 4: 1 to 2: 3). . This composition is excellent in foaming power, but sufficient storage stability is not obtained.
The JP-A-07-109484 and JP 07-188696, but detergent composition in combination with polyglycerin C ₈ -C ₁₀ fatty acid ester with sucrose C ₁₀ -C ₁₄ fatty acid monoesters have been described, Foaming power and foam persistence are not sufficient.
Further, JP-A-49-41404, JP-A-51-55306 and JP-A-09-3488 describe cleaning compositions containing sucrose fatty acid ester as a cleaning agent active ingredient. A sucrose fatty acid ester alone system as an active ingredient is excellent in foaming power and storage stability, but has a drawback of poor foam persistence.
Furthermore, Japanese Patent Laid-Open No. 9-176689 discloses a disinfecting detergent composition containing decaglycerin C ₈ fatty acid (caprylic acid) ester and sucrose C ₁₂ fatty acid (lauric acid) ester in a weight ratio of 0.67-4. However, sufficient storage stability is not obtained.
[0004]
[Problems to be solved by the invention]
An object of this invention is to provide the cleaning composition which is excellent in storage stability, foaming power, and foam persistence, and is safe for a human body.
[0005]
[Means for Solving the Problems]
The present inventors have found that the above object can be achieved by blending a specific polyglycerin fatty acid ester and a sucrose fatty acid ester in a specific ratio.

No. 4,515,775), (5) addition polymerization reaction between glycidol and the corresponding fatty acid ( For example, it is compoundable by Unexamined-Japanese-Patent No. 51-65707. Of these, those synthesized by the reactions (1) and (5) are preferred, and those synthesized by the reaction (5) are more preferred.
[0008]
The polyglycerol fatty acid ester is usually a mixture of fatty acid esters of polyglycerol having different degrees of polymerization. The average degree of polymerization of polyglycerin is determined by end group analysis. In this end group analysis method, the polymerization degree (n) and molecular weight (MW) of polyglycerin are determined from the relationship between the measured value of hydroxylation (OHV) and the theoretical value by the following formula [[polyglycerin ester, 34 (October 3, 1994, published by Sakamoto Pharmaceutical Co., Ltd.)].
MW = 74n + 18
OHV = 56110 (n + 2) / MW
[0009]
