Problems solved by technology

[0006] Aiming at the series of defects in the laundry detergent prepared by the prior art, the present invention aims to use the branched fatty alcohol silicon-containing polyurethane sulfonic acid surfactant prepared by polyurethane synthesis technology, and adopt a more optimized formula and process to prepare special-effect laundry detergent. The multiple lipophilic end groups of branched fatty alcohols, the low surface tension of silicone and the good hydrophilicity of sulfonic acid surfactants solve the problem of strong irritation and easy pollution when using traditional detergents, and the existing laundry detergent The liquid has defects such as poor washing ability and limited effect of caring for clothes

Abstract

The invention provides a special-effect laundry detergent based on a branched fatty alcohol containing silicon polyurethane sulfonic acid type surface active agent and a preparation method thereof. The special-effect laundry detergent comprises the following components: the branched fatty alcohol containing silicon polyurethane sulfonic acid type surface active agent, a non-ionic surface active agent, a plant extracting liquor, an enzymic preparation, a brightener, a defoamer and a mould-proof sterilizing agent. The branched fatty alcohol containing silicon polyurethane sulfonic acid type surface active agent is mixed and stirred with the non-ionic surface active agent, and then the plant extracting liquor, the enzymic preparation, the brightener, the defoamer and the mould-proof sterilizing agent are added in turn, and the mixture is stirred, so that the special-effect laundry detergent is acquired. The technique and the formula according to the invention meet the modern environment-friendly requirement. The special-effect laundry detergent has ultrahigh washing ability and excellent maintaining effect, can be widely used for washing and maintaining the textile, such as, clothing, curtains, bedding articles, and the like, and has ultrahigh environmental protection benefit, social benefit and economic benefit.

Description

technical field [0001] The invention relates to a special-effect laundry liquid, and mainly relates to a special-effect laundry liquid with super-strong cleaning and caring effects based on a branched fatty alcohol silicon-containing polyurethane sulfonic acid surfactant and a preparation method thereof. Background technique [0002] Detergent is a daily-use chemical used to clean objects. my country is the most populous country in the world. The amount of detergent has increased from 6.92 million tons in 2009 to 10.3 million tons in 2014, and the market consumption has exceeded 300 billion yuan. Traditional detergents (such as washing powder, soap) use anionic surfactants, mainly sodium stearate, etc., which are highly alkaline (pH>12) and usually contain phosphorus. When used, they are harmful to the skin. Stimulation and damage are greater, and its washing wastewater is likely to cause pollution such as "eutrophication". The new type of laundry detergent mostly uses n...
