Problems solved by technology

[0005] In order to overcome the problem that the viscosity of the detergent fluctuates too much with the change of temperature, which affects the consumer experience (specifically, when the temperature is relatively high, the viscosity of the detergent is too low to stick to the hands; when the temperature is relatively low, the washing The viscosity of the agent is too high to cause nozzle clogging), the object of the present invention is to provide a method of giving detergent composition a small range of viscosity changes in a wide temperature range and related compositions

Abstract

The invention discloses a method for enabling detergent composition to have small-range viscosity change in a wide temperature range and the related detergent composition. 2%-20% of a special amphoteric surfactant is used in the method. The amphoteric surfactant meets conditions as follows: 1), the amphoteric surfactant is selected from a mixture of two or three of an amino acid type amphoteric surfactant, a betaine type amphoteric surfactant and an imidazoline type surfactant; 2), the amphoteric surfactant at least contains one amino acid type amphoteric surfactant. The wide temperature range is 0-40 DEG C, and the small-range viscosity change means that the viscosity ranges from 500 mPa*s to 5,500 mPa*s. The detergent composition prepared with the method is conveniently extruded out by a conventional press type pump head, and the pump head can be effectively prevented from being blocked due to temperature decrease in winter.

Description

technical field [0001] The invention belongs to the technical field of daily chemical products, in particular to a detergent composition whose viscosity changes in a small range within a wide temperature range. Background technique [0002] The research on the application of amino acid surfactants began in the 1970s. They are mainly used in the antisepsis of medicines and cosmetics, and have good antiviral properties. In recent years, amino acid surfactants have attracted more and more attention from scientific research teams because of their excellent performance, and their application fields have been further expanded. Amino acid surfactants can be simply divided into two categories according to their structure: 1) they are composed of fatty α-amino acids connected to each other through amide bonds; 2) they are composed of natural α-amino acids and long fatty chains through α-amino, α-Carboxyl group or branched chain group connected together. At present, the latter is th...
