Description

Method for imparting gel properties to detergent composition and high water content gel type detergent combination

technical field

The invention belongs to the technical field of daily chemical products, and in particular relates to a high-water-content detergent composition having both gel properties and fast-dissolving properties.

Background technique

The research on the application of amino acid surfactants began in the 1970s. They are mainly used in the antisepsis of medicines and cosmetics, and have good antiviral properties. In recent years, amino acid surfactants have attracted more and more attention from scientific research teams because of their excellent performance, and their application fields have been further expanded. Amino acid surfactants can be simply divided into two categories according to their structure: 1) they are composed of fatty α-amino acids connected to each other through amide bonds; 2) they are composed of natural α-amino acids and long fatty chains through α-amino, α-Carboxyl group or branched chain group connected together. At present, the latter is the main research and application at home and abroad. Among them, N-acyl, O-acyl, N-alkylamino compounds and their esters are widely used in the daily chemical industry because of their low toxicity and high biodegradability. Pay attention to.

In the daily chemical industry, detergents for different purposes usually have different viscosity requirements. Generally speaking, the viscosity of household detergents such as detergent, laundry detergent, shower gel, etc. will be between 200mPa·s and 10000mPa·s. On the one hand, the viscosity meets the needs of actual use, such as being easy to apply and wipe, and on the other hand, it also meets the emotional needs of consumers. The gel-state detergent can meet other functional needs, such as not easy to spill due to collision during carrying, and easy to make unit-dose detergent packaging.

At present, major manufacturers mainly form gels by adding various polymer thickeners, such as polyethylene glycol and polysaccharides. Although polymer can solve the problem of gelling, it will add other defects to the product, such as gelatinous appearance at low temperature; discoloration at high temperature; foaming properties of surfactants are suppressed; skin feel is affected by polymers during cleaning, It is sticky, dirty, and has a strong residue; the high price of polymers occupies the cost space of the formula; the formed gel has poor water solubility. Throughout the public literature at home and abroad, there is no detergent composition with gel properties, shear thinning properties and fast dissolution properties.

The loss modulus G, also known as the viscous modulus, refers to the amount of energy lost due to viscous deformation (irreversible) when the material is deformed, reflecting the viscosity of the material . When the storage modulus G' is much greater than the loss modulus G", the material mainly undergoes elastic deformation, so the material exhibits the characteristics of an elastomer. When the loss modulus G" is much greater than the storage modulus G', the material mainly undergoes viscous deformation , so the material exhibits the characteristics of a viscous body. The gel characteristic of the present invention means that the G' value of the gel system of the present invention is greater than G", showing the characteristics of an elastomer, specifically manifested in that the viscosity of the detergent composition of the present invention is above 130,000 mPa·s and when the composition is loaded The composition does not flow within 5 minutes when the container is inverted.

Usually, when the liquid detergent is subjected to the rheometer oscillation frequency sweep test, the loss modulus G" is always greater than the storage modulus G' in the test area, and the G" curve and the G' curve have no intersection point, and only show the characteristics of a viscous body .

The inventors found that based on the combination of zwitterionic surfactants, the detergent composition formed a worm-like micelle structure and obtained special fluid properties. When using a rheometer to perform an oscillation frequency sweep test (25°C), G "The curve intersects the G' curve, the loss modulus G" in the low frequency region is higher than the storage modulus G', and the storage modulus G' in the high frequency region is higher than the loss modulus G", that is, it is described under different strain rates Detergent compositions can exhibit viscous and elastomeric characteristics, respectively.
