CS230133B1 - Liquid work detergent for wool and delicate laundry - Google Patents

Abstract

The invention relates to liquid detergents for wool and delicate laundry. In recent years, the development of detergents has focused on liquid mixtures of surfactants and auxiliary substances. These liquid forms of detergents have a number of advantages over powder detergents, for example, rapid solubility, simple dosing, are well suited for local removal of dirt (stains) and their quality is not affected by air humidity, which entails lower storage requirements for finished products, easy preparation and saving of thermal energy required for powdering. The main component of liquid detergents for wool and delicate laundry is usually sodium alkylbenzenesulfonate and alkyl sulfate, and they also contain aliphatic or aromatic ethylene oxide adducts, fatty acid amides, ethanol, propylene glycol, toluene-xylene or cumyl sulfonate, pyrophosphate, metasilicate, water, sequestering agent, perfume, and possibly optical brighteners. The disadvantages of the said liquid detergents lie in the poor maintenance of the permanent fluidity of the liquid formulations caused by the addition of electrolytes, in particular phosphates, as auxiliary substances.

Description

The invention relates to liquid laundry detergents for wool and delicate laundry. The development of laundry detergents in recent years has focused on liquid mixtures of surfactants and excipients. These liquid detergent forms have a number of advantages over powder formulations, such as rapid solubility, simple dosing, well suited for local removal of stains, and its quality is not affected by air humidity, resulting in lower storage requirements for finished products, easy preparation and savings the thermal energy required for dusting.

The main constituents of liquid laundry detergents for wool and delicate fabrics are usually sodium alkylphenensulfonate and alkyl sulfate, further containing aliphatic or aromatic ethylene oxide adducts, fatty acid amides, ethanol, propylene glycol, toluene-xylene or cumyl sulfonate, pyrophosphate, metasilicate, water , a sequestering agent, a perfume, optionally an optical brightener.

The disadvantages of said liquid detergent compositions are the poor sustainability of the continuous flowability of liquid formulations caused by the addition of electrolytes, especially phosphates, as excipients.
