Abstract

The invention relates to a washing agent and a preparation method thereof. The washing agent is prepared from the following components in parts by weight: 10-12 parts of lauramidopropylamine oxide, 5-8 parts of cocamidopropyl betaine, 5-8 parts of fatty alcohol polyoxyethylene ether sodium sulfosuccinate, 0.1-3 parts of methyl hydroxypropyl cellulose, 1-3 parts of oxalic acid, 3-6 parts of polyethylene glycol, 0.5-2 parts of Kathon, 0.5-1 part of propyl p-hydroxybenzoate, 0.1-0.5 part of essence and 35-58 parts of deionized water, and also is prepared from 1-3 parts of mint extract, 3-5 partsof mugwort extract and 3-5 parts of pomegranate bark extract. The washing agent prepared by adopting a matching ratio has the advantages of mildness, strong dirt-removing capability, long bacteriostatic time and inhibition for redeposition of dirt particles onto fabrics.

Description

technical field [0001] The invention relates to the field of fabric washing, more specifically, it relates to a detergent and a preparation method thereof. Background technique [0002] Large hotels or guesthouses need to receive a large number of floating people, and need to change and wash a large number of common bed sheets, quilt covers or table cloths every day. Since these items are public goods, in order to avoid residual bacteria or viruses, hotels or guesthouses usually use a large amount of alkaline substances such as bleach or carbonate to make bed sheets, quilt covers or tablecloths look clean and tidy. However, due to the reaction of carbonate and hard water, it is easy to produce water-insoluble calcium carbonate crystals, and after a long time of use, it is easy to make the clothes hard. [0003] The Chinese patent whose application publication number is CN103215142A discloses a kind of washing and softening two-in-one laundry liquid, which improves the flexi...
