Dispersantes homopolímeros acrílicos y copolímeros acrílico-maleicos para detergentes

Acrylic Dispersing Agents

Sodium tripolyphosphate is the most widely used dispersing agent during the 20th century. It is very effective, and has been one of the main adjuvants in the manufacture of detergents. In addition to being a dispersing agent, it is a water hardness sequestrant, an emulsifier and a stabiliser. However, the massive use of phosphates has…

Tensioactivos de baja espuma para detergentes

Low-foaming surfactants

Surfactants Surfactants are organic molecules that modify the surface forces, i.e., the attraction between molecules of a liquid on its surface. They are used in detergents as they help to dissolve or emulsify water-insoluble substances. Surfactants have emulsifying, wetting, detergent and foaming properties. The classification of surfactants is based on the charge they possess when…

Antimicrobial N2000: the MIT-free preservative for effective fabric softeners at low concentration and wide pH range

The detergency industry is moving quickly to find substitutes for MIT (Methylisothiazolinone) as preservatives, forced by a change in legislation that will take effect next May. One of these substitutes is the Antimicrobial N2000: a 35% solution of dodecylguanidine hydrochloride (DGH) in propylene glycol/dipropylene glycol used to control algae, bacteria and fungi. DGH is a…

Novethix™ HC-220 non-ionic thickeners

In detergents, thickeners are used to facilitate the dosing of the products or to achieve superior adhesion to the surfaces, and thus increase the contact time of the preparations on the surfaces. Many thickeners of an anionic nature are highly performant as modifiers of viscosity, flow type or suspension capacity, but are incompatible with cationic…

sorbatos como conservantes para detergentes

Maintenance of detergents with sorbates

Many preservatives commonly used in detergency are being discontinued due to regulatory changes. This, together with the tendency to formulate with substances that respect health and the environment, generates the need to find new alternatives to conserve detergents. Sorbates: non-sensitizing preservatives existing in nature Sorbates are molecules found in some natural products, such as mountain…
