Composition for alpha-sulfo fatty acid alkyl ester salt-containing detergent, and application thereof

Abstract

The invention discloses a composition for alpha-sulfo fatty acid alkyl ester salt-containing detergent, and the composition is prepared from the following raw materials by weight percent: 1.0-6.0% of non-ionic surface active agent, 65.0-94.0% of powdered alpha-sulfo fatty acid alkyl ester salt and 5.0-34.0% of zeolite. The invention also discloses an application of the composition. The composition has good fluidity, can be used for remarkably improving the stability of products in the storage process when being applied to the detergent powder formulation, and effectively inhibiting the generation of unpleasant smell.

Description

technical field

[0001] The invention relates to a detergent composition, in particular to a detergent composition containing α-sulfo fatty acid alkyl ester salt (MES), and also relates to the application of the detergent composition. Background technique

[0002] α-Sulfo fatty acid alkyl ester salt (MES) is a product obtained by sulfonating and neutralizing natural raw materials such as coconut oil and palm oil. It is a surfactant with good performance. Excellent calcium soap dispersibility, low irritation and good biodegradability, compared with the currently used surfactants, it has considerable advantages in cost performance, and has environmental protection significance. It is used to replace petroleum by-product alkylbenzene sulfonic acid The development and application of salt in detergents and personal care products is of great significance to solve the common problem of the industry's long-term dependence on petroleum, and has broad prospects for application in the w...

Embodiment Construction

[0025] The present invention is described below in conjunction with embodiment and test example.

[0026] As the embodiment nonionic surfactant of the present invention adopts ethoxylated alcohol nonionic surfactant, comprises the ethoxylated C of the average ethoxylation degree of 3~10 10~16 Alcohols, such as: AEO7, AEO9, XL-80, SA-9, FMEE, TO-10, etc. Further, the present invention preferably has an ethoxylated C with an average degree of ethoxylation of 7-9. 10~16 Straight chain alcohol or branched chain alcohol, such as: AEO7, AEO9, XL-80, etc. The zeolite adopts the 4A zeolite raw material used in washing industry.

[0027] The general formula of α-sulfo fatty acid alkyl ester salt is:

[0028] ,

[0029] Among them, R 1 is an alkyl group with an average carbon number of 8 to 20, R 2 It is an alkyl group with an average carbon number of 1 to 4, n=1 or 2, and M is selected from Na + 、K + , Li + , NH 4 + , Ca 2+ , Mg 2+ or their mixtures. Preferred R 1 is a...
