Abstract

The invention discloses a liquid detergent. The liquid detergent comprises the following components in percentage by weight: 10-20 percent of fatty alcohol-polyoxyethylene ether, 5-8 percent of fatty alcohol polyoxyethylene lauryl ether sulfate sodium, 1-6 percent of alpha-olefin sulfonate, 1-5 percent of sec-alkyl sodium sulfate, 5-10 percent of coconut oil fatty acid diethanolamine, 0.5-1 percent of protease, 1-5 percent of an enzyme stabilizer, 0.1-1 percent of a builder, 0.05-0.5 percent of a fluorescent brightening agent, 0.05-0.5 percent of essence, and the balance of deionized water. The liquid detergent has a good stain removal effect, can effectively remove various intractable dirts on the surface of fabric, meanwhile can prevent secondary sedimentation of the dirt, has a better capacity of modifying the color on the surface of the fabric, and can ensure that the fabric is bright in color as a new one after washing.

Description

A kind of washing liquid

Technical field

The invention belongs to daily-use chemical industry washing composition technical field, relate generally to a kind of washing liquid.

Background technology

Washing liquid is a kind of convenient to use, well behaved daily cleaning articles for use, has adapted to high-level efficiency, the life of allegro modern house, becomes the new highlight on washing market.Washing liquid is compared with traditional washing powder, there is unique superiority, do not need prior dissolving, can mix rapidly with water, there will not be dust and caking phenomenon, decontamination is even, can also wash by low-temperature cold water, do not hinder hand, do not damage clothing, because chemical substance in washing liquid is less, pollution on the environment is also relatively little.In use, washing liquid solvability is better, and the effect of a rinsing of washing liquid is equivalent to the effect of 3 rinsings of standard washing powder, therefore more energy-conserving and environment-protective.

Human body is daily to be touched as contained a large amount of protein in gravy, egg, blood, milk, sweat, green grass, makeup, human secretion and scurf, these protein attachment form dirt to fabric, and big area is expanded on fiber, dry, of long duration can become poorly water-soluble, the extremely difficult colloid degeneration protein of washing off, in addition these protein(aceous)soils can also be bonded together other dusts, particulate species dirt, promote the microbial reproduction such as bacterium, mould, produce new dirt, fabric generation variable color is hardened, and fibre property worsens.These special spots, general washing composition is difficult to remove clean, therefore needs to develop a kind of novel washing liquid and removes these stains.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of washing liquid that adds enzyme, in washing composition, add enzyme special organic dirt can be resolved into small molecules thing, increased the water-soluble of dirt, thereby more easily washing is disposed, reached effect clean, decontamination.

The technical scheme that the present invention will provide is a kind of washing liquid, and it comprises that the component of following weight per-cent forms:

Fatty alcohol-polyoxyethylene ether 10～20%, polyoxyethylenated alcohol sodium sulfate 5～8%, α-sodium olefin sulfonate 1～6%, Teepol 1～5%, coco-nut oil fatty acid diethanolamine 5～10%, proteinase-10 .5～1%, enzyme stabilizers 1～5%, washing assistant 0.1～1%, white dyes 0.05～0.5%, essence 0.05～0.5%, surplus are deionized water.

Preferably, above-mentioned proteolytic enzyme is Sumizyme MP.

Preferably, above-mentioned enzyme stabilizers is sodium formiate, acetic acid, oxalic acid or propylene glycol.

Preferably, above-mentioned washing assistant is the composite mixture of Trisodium Citrate and trolamine, and regulating the pH scope of washing liquid by washing assistant is 8～9.Trisodium Citrate has sequestering action, and the calcium ions and magnesium ions in water is combined, and generates soluble complexes, has both saved tensio-active agent, avoids again on fabric, leaving dirt throw out simultaneously, makes washing clothes keep being in bright colors.And thanomin can reduce the water hardness, eliminate the impact of calcium ions and magnesium ions on cleaning function, alkali source is provided, dirt is had to suspended dispersed effect, there is collaborative soil removability with tensio-active agent.

Preferably, above-mentioned white dyes is distyryl biphenyl fluorescent bleaches.

Preferably, this washing liquid also comprises 0.05～0.2% sanitas.

Compared with prior art, the present invention, take nonionic surface active agent as main, is aided with anion surfactant, and these compositions and proteolytic enzyme have good consistency and compatibleness, are easy to biological degradation, strong detergency.In this product, add after proteolytic enzyme, clean effect significantly strengthens, and can effectively remove the intractable dirts such as milk, egg, dish juice, and adding of enzyme stabilizers makes to have good shelf-life and package stability after this product.This product of life-time service, can make washing clothes bright in colour as new.
