JP4423237B2 - Thickener for cleaning agent - Google Patents

Description

  The present invention is one or more selected from the group consisting of (A) α-monoalkyl polyglyceryl ether, (B) α-monoalkenyl polyglyceryl ether and (C) α-monohydroxyalkyl polyglyceryl ether having a specific structure. The present invention relates to a thickener for a cleaning agent characterized by containing an alkyl polyglyceryl ether, and a high-viscosity liquid cleaning agent containing the same.

  In order to improve the practical handling of the cleaning composition, or to stably disperse the pearl agent, abrasive and water-insoluble substances, the composition is variously increased for the purpose of increasing the viscosity of the composition. Contains a sticky agent.

  The main conventional thickening techniques are the method aiming at micelle aggregation of a detergent composition such as an inorganic salt such as sodium chloride, the method of blending a polymeric thickener, and the electrical interaction between the surfactant molecules. Examples include a method using an action. Fatty acid alkanolamides are the most commonly used thickeners. Fatty acid alkanolamides are surfactants that have a very good thickening effect and foam-stabilizing effect, especially when combined with anionic surfactants, but N-nitrosodiethanolamine contained in them has been released by the US Food and Drug Administration. Since it has been pointed out that it is cancerous and there are concerns about safety issues, the development of a thickener to replace fatty acid alkanolamides has been desired.

  Therefore, some thickeners that can be substituted for aliphatic alkanolamides have been disclosed in the past, and propylene glycol monofatty acid esters having 8 to 14 carbon atoms (see, for example, Patent Document 1), alkyl glyceryl ethers having 12 to 20 carbon atoms. (For example, refer patent document 2), C8-12 polyglycerol mono fatty acid ester (for example refer patent document 3), etc. are disclosed. However, these thickeners do not satisfy all of the thickening effect, the foaming stability effect, and the low temperature stability.
