Embodiment 1

[0019] A neutral low-foaming laundry detergent containing natural oil, its components and parts by mass are:

[0020]

[0021] Among them, tallow and sheep oil are imported from New Zealand, sodium chloride is a thickener, disodium edetate is a chelating agent, and 2-methylisothiazol-3(2H)-one (MIT) is a preservative agent.

[0022] The preparation method of the neutral low-foaming laundry detergent containing natural oil of embodiment 1 is as follows:

[0023] 1. Add 74 parts of measured deionized water in turn, heat up to 50°C-60°C, add tallow and suet and caustic soda while stirring, then add 8 parts of fatty alcohol polyoxyethylene ether sodium sulfate (AES), 3 parts of coconut Oleic acid diethanolamide, 2 parts of fatty alcohol polyoxyethylene (7) ether, 3 parts of fatty alcohol polyoxyethylene (9) ether, stirred to dissolve.

[0024] 2. Cool down to below 30°C, add 1 part of alkylbenzenesulfonic acid, 3 parts of PA 25CL polyacrylic acid sodium salt, 0.1 part of diso...

Embodiment 2

[0027] According to the same preparation method as in Example 1, the neutral low-foaming laundry detergent containing natural oil with the following main active components and mass parts is prepared:

[0028]

[0029] Wherein, tallow and sheep oil are selected from New Zealand imported tallow and sheep oil, sodium chloride is a thickening agent, sodium citrate obtained by neutralizing citric acid is a chelating agent, and 2-methylisothiazol-3 (2H)-ketone ( MIT) as a preservative.

[0030] It is found through application experiments that examples one and two can effectively reduce suds in the washing process, because soap and Ca in hard water 2+ , Mg 2+ Generate water-insoluble calcium soap and magnesium soap, thereby breaking the foam and having the effect of defoaming. According to GB / T 7462-1994 "Determination of the Foaming Power of Surfactants, Improved Ross-Miles Method" to measure the foam volume, compared with the same formula laundry detergent without adding natur...

Abstract

The invention relates to a neutral low-foam liquid laundry detergent containing natural grease. The natural low-foam liquid laundry detergent comprises the following main active components, by mass, 10-25 parts of a surfactant, 1-9 parts of natural grease, 0.3-3 parts of an alkali, 1-5 parts of a neutralizing acid, 0.1-1 part of a chelating agent, 1-5 parts of an anti-redeposition agent and 0.5-5 parts of a thickening agent. The neutral low-foam liquid laundry detergent containing natural grease has the characteristics of foam breaking and inhibiting effects, cloth protection, neutrality, no irradiation, and easy rinsing.

Description

technical field [0001] The invention relates to a detergent, in particular to a neutral low-foaming laundry detergent containing natural oil. Background technique [0002] With the rapid development of laundry detergent, the market has gradually matured, and the functionality of laundry detergent has become stronger and stronger. At present, there are two types of laundry detergent containing defoamers, one is polyether defoamer, and the other is polyether modified silicone defoamer. Poor foam suppression ability. The latter has good defoaming effect, but poor stability. [0003] As society and consumers have higher and higher functional requirements for laundry detergent, it is very desirable to have a laundry detergent that has good water solubility and low irritation properties, and at the same time can achieve low foam, easy rinsing, and biodegradability. Good performance and good stability. This puts higher demands on our products. Thus, developing a kind of neutra...
