Low-foam easy-to-rinse laundry detergent containing enzyme preparation and preparation method thereof

Abstract

The invention belongs to the technical field of washing products, and particularly relates to a low-foam easy-to-rinse laundry detergent containing an enzyme preparation and a preparation method thereof. The low-foam easy-to-rinse laundry detergent comprises the following components in parts by mass: 8 to 23 percent of LAS, 5 to 12 percent of methyl cocoate ethoxylate, 0.1 to 2 percent of saturated fatty acid, 0.5 to 1.5 percent of an enzyme preparation, 1 to 5 percent of an enzyme preparation stabilizer, 0.1 to 2 percent of a thickener, 0.1 to 2 percent of potassium hydroxide, 0.1 to 0.3 percent of a preservative, 0.1 to 1 percent of a chelating agent, 0.1 to 0.3 percent of a pH regulator and 60 to 75 percent of deionized water. The low-foam performance is achieved by adding the saturatedfatty acid, meanwhile, the methyl cocoate ethoxylate and the saturated fatty acid salt are compounded, the bleaching ability of the laundry detergent is remarkably improved, and the prepared laundrydetergent is high in detergency, has good detergency for various stains and has a certain stain re-precipitation resisting effect.

Description

technical field [0001] The invention belongs to the technical field of washing products. More specifically, it relates to a low-foaming and easy-rinsing laundry detergent containing an enzyme preparation. Background technique [0002] Low-foaming and easy-rinse is a new trend in the development of laundry detergent products. This new trend is conducive to saving energy consumption and carbon emissions, while consumers themselves also save costs. [0003] At present, in order to achieve low-foaming and easy-rinsing effects, low-foaming surfactants, saturated fatty acid salts or defoamers are mainly used in laundry detergent formulas to achieve defoaming and suppress foam generation. For example, Chinese patent CN106398903B discloses an easy-rinsing Hand-washing laundry detergent, which achieves the purpose of defoaming and improving easy-rinsing performance by adding potassium laurate and potassium oleate; as in Chinese patent CN103013723B, silicone is used as a defoaming ag...

Problems solved by technology

Although silicone can defoam quickly, it cannot improve the bleachability of laundry detergent, and laundry detergent with silicone defoamer is prone to delamination at high temperatures.

[0004] In the above three approaches, saturated fatty acid salts can form water-insoluble calcium soaps and magnesium soaps with calcium ions and magnesium ions in hard water, causing the foam to burst and simultaneously improve its ease of rinsing to a certain extent. Generally, the defoaming effect is achieved by adding fatty acids and alkaline agents to the laundry detergent formula to form fatty acid salts, but the ideal easy-rinsing and defoaming effects need to be satisfied when the amount is greater than 3%, and the content is higher than 3% % Fatty acid salts are prone to fat salt precipitation at low temperature

Therefore, if fatty acid salts are used to realize the easy-rinsing function of laundry detergent, the problem of poor low-temperature stability of saturated fatty acid salts must be solved.
