A non-linear surfactant, and particularly a non-linear surfactant comprising bi-functionalized molecules or particles having both hydrophobic and hydrophilic groups. The non-linear surfactant includes a nanoparticle template of a rigid molecular structure, wherein the nanoparticle comprises a molecule or a particle that is bi-functionalized with both hydrophilic and hydrophobic groups to obtain an amphiphilic nanoparticle. The template nanoparticle can be used as a surfactant, wetting agent, emulsifier, detergent or other surface active agents or for the preparation of nanoemulsions or dispersions. The non-linear surfactant can provide smaller particle sizes for emulsion suspensions and foams.

The invention provides a method of inhibiting lipase activity in a detergent composition, said method involving incorporation of from 0.25 to 40 wt. % of a saponin into said lipase containing composition, wherein said detergent composition preferably is a home care detergent composition, more preferably a laundry detergent composition; and to the use of saponin to inhibit lipase activity in a detergent composition, preferably a laundry detergent composition, wherein the saponin is present in the detergent formulation at a level of from 0.25 to 40 wt. %, wherein said detergent composition preferably is a home care detergent composition, more preferably a laundry detergent composition.

A process for extracting biosurfactants from the solid content in corn steep liquor, using a buffered aqueous solution having a pH of 6-8 and a biosurfactant extract obtained using the process of the invention, and the uses in cosmetics, food, pharmaceutical, agrochemical and environmental industries. The obtained biosurfactant has the form of a white powder with foaming capacity and is able to reduce water surface tension by at least 16-20 units.

The proposed cluster of inventions relates to chemical industry, in particular to compositions of and additives in detergents designed for household, professional or personal use, to be used at home or industrially. The essence of this cluster of inventions lays in the use of polysaccharide microgels as an additive or the base in detergents, in particular as an antiresorption agent, thickener, or an agent for reducing surface tension at the interphase boundary, including also composition of detergents with polysaccharide microgels. The technological result of the application of these inventions is reduction of the quantity of surfactants in the detergent, while its detergency is no affected, which raises their ecological value and safety for the final users.
