A kind of liquid detergent composition and the method for adjusting its rheological property

Abstract

The invention discloses a liquid detergent composition and a method for adjusting its rheological properties. The liquid detergent composition contains a rheology modifier (CnHmCOO-)xMx+ and a block copolymer of polyethylene glycol and polyethylene glycol terephthalate; wherein (CnHmCOO-)xMx+ meets the following conditions a1) simultaneously, a2), a3), a4): a1) 20≥n≥1; a2) 41≥m≥1; a3) M is a metal ion or a positively charged group; a4) 3≥x≥1; the poly The molecular structural formula of the block copolymer of ethylene glycol and polyethylene glycol terephthalate is: the weight average molecular weight is 500-10000, wherein, preferably: 1400-5100. The composition of the invention has good rheological properties at various temperatures such as high temperature, normal temperature and low temperature.

Description

technical field [0001] The invention relates to a detergent composition, which belongs to the technical field of daily chemical cleaning products, in particular to a liquid detergent composition with better rheological properties and a method for adjusting the rheological properties. Background technique [0002] The rheological properties of liquid detergents are a very important factor affecting consumer experience and product quality. In order to make consumers easy to use and meet the appearance requirements of the product, liquid detergent products need to have certain rheological properties. Based on the existing liquid detergent formula design, the viscosity of many liquid detergents will increase sharply under low temperature conditions, and become particularly viscous and difficult to pour, which brings inconvenience to consumers; while under high temperature conditions, the viscosity It will decrease rapidly and become very thin, which also gives consumers a very ...

Problems solved by technology

Chinese patent CN103242974A discloses a fruit and vegetable tableware detergent with good rheology, and a viscosity regulator is added to the detergent: one or both of PPG-20 methyl glucose ether, PPG-10 methyl glucose ether, glycerin, and propylene glycol. More than one, used to reduce the influence of temperature on the viscosity of liquid detergents, but this solution can only solve the problem of high viscosity of liquid detergents at low temperatures, and does not involve the technical solution to solve the problem of too thin viscosity of liquid detergents at high temperatures

[0004] Although the above-mentioned patents provide an adjustment scheme for solving the rheological properties of liquid detergents at room temperature or low temperature, the adjustment schemes for simultaneously solving the rheological properties of liquid detergents at various temperatures such as high temperature, normal temperature, and low temperature are not involved.
