With the development of society and the improvement of consumption levels, people's demand for detergents is also increasing. In addition to requiring good detergency, it also requires other functions, such as long-lasting fragrance, suppleness, gentleness, no hand injury, easy rinsing, color protection and sterilization. In order to meet the needs of consumers, the laundry liquid product market has also introduced products containing these effects.
Laundry liquid formula technology introduction
As a detergent, laundry detergent should be considered for decontamination performance. Detergency performance includes a detergency and secondary detergency. A decontamination force refers to the whiteness, bleaching property of the fabric after washing, and the decontamination performance of the detergent on dirt and fat; the secondary detergency refers to the brightness retention of the fabric after the second washing, that is, the formula must have The ability to prevent dirt deposits and modify the color of the fabric surface. If the detergent has poor secondary detergency, the fabric will be hardened and rough due to dirt, which will reduce the service life of the fabric, and the surface of the fabric will become dull due to the ash.
Detergency is generally improved by three ways to improve detergency, including anionic surfactant / nonionic surfactant compounding, enzymes in the formulation and the addition of builders to improve detergency.
The decontaminating effect is mainly surfactant, which is compounded with anionic surfactant/nonionic surfactant to improve the stability of the formulation at low temperature and improve the detergency. For example, fatty acid soap, AOS, LAS, AES and AEO are compounded. AES and LAS have good ability to remove particulate dirt and dust and dirt, and AES has good resistance to hard water, which can compensate for the hard water resistance of LAS. AEO The degreasing performance is better.
