Abstract

The invention belongs to the technical field of daily-use chemistry, and particularly relates to a super-concentrated liquid detergent and a preparation method thereof. The super-concentrated liquid detergent is prepared from fatty alcohol ether sodium sulfate, fatty alcohol-polyoxyethylene ether, C21 dibasic acid potassium, propylene glycol, trisodium citrate, essence, pigment, a viscosity modifier and water. The preparation method comprises the following steps: adding the raw materials in proportion at different temperatures, fully stirring, adjusting the pH value and viscosity of the samplein the stirring process, standing for defoaming, sampling to test the pH value, viscosity, smell and appearance, and transferring to a sample bottle after the sample is qualified. The anionic surfactant C21 dibasic acid potassium is added into the super-concentrated liquid detergent disclosed by the invention; the high-concentration super-concentrated liquid detergent overcomes the defect that the existing high-concentration super-concentrated liquid detergent with high active matter content is poor in flowability, and the prepared detergent is mild, non-irritant, good in biodegradability, excellent in decontamination performance, safe, non-toxic, rich in raw material source, low in cost, simple in preparation process and free of environmental pollution.

Description

technical field [0001] The invention belongs to the field of daily chemical technology, and in particular relates to a super-concentrated liquid detergent and a preparation method thereof. Background technique [0002] With the advent of the global low-carbon, green and environmental protection era, domestic detergent products and markets are gradually catching up with international standards. Concentration is an important trend in today's detergent research and market development. New concentrated fabric detergents, concentrated fabric softeners, and concentrated household cleaners have appeared in people's daily life one after another, and are accepted by consumers for their excellent performance. Compared with the high market share in developed countries, domestic liquid detergents are obviously less, and concentrated liquid detergent products are still in their infancy, and the existing high-concentration super-concentrated liquid detergents with large active substance c...
