Pre-cleaning agent

Abstract

The invention discloses a pre-cleaning agent, which consists of the following ingredients in percentage by mass: 30 to 40 percent of methyl soyate, 10 to 15 percent of alcohol ethoxylate (AEO)-9, 3 to 5 percent of ethanol, 3 to 5 percent of propanediol butyl ether, 2 to 4 percent of sodium citrate and the balance naphtha. The pre-cleaning agent is used for carrying out local pre-cleaning on heavy-dirt parts before the integral washing of clothes. The pre-cleaning agent is mainly used for shirt collars and sleeves and can also be used for parts with difficult-to-wash stain such as fabric oil stain, protein, fruit stain, mildew spots, color spots and the like. The stain is dissolved, emulsified and decomposed in advance so that the corresponding stain can be preferably removed during the washing.

Description

Technical field

[0001] The invention relates to a detergent, in particular to a pre-spotting agent. Background technique

[0002] The pre-stain remover is used in the pretreatment of fabric washing to remove local stains through solubilization, emulsification, dissolution or biodegradation.

[0003] Currently, there is no effective pre-spotting agent. Summary of the invention

[0004] The technical problem to be solved by the present invention provides a pre-spotting agent.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A pre-spotting agent consisting of the following components in mass percentage:

[0007] Soybean oil methyl ester 30~40%,

[0008] AEO-9 10~15%,

[0009] Ethanol 3~5%,

[0010] Propylene glycol n-butyl ether 3~5%,

[0011] Sodium citrate 2~4%,

[0012] The balance is naphtha.

[0013] The above components are stirred and mixed uniformly at about 50° C. to obtain the pre-spotting agent of the present invention. [0...
