Low foaming surfactants > for chemical-technical applications

BTC´s low foaming surfactants are derived from natural and synthetic alcohols. Their use in chemical-technical formulations is versatile. Besides others they are applied in the pulp & paper industry, in metal treatment applications and in the textile industry for pre-treatment purposes.



Properties of our low foaming surfactants for chemical-technical applications

BTC’s Plurafac® grades are fatty alcohol alkoxylates. They are petrochemical sourced and are low foaming nonionic surfactants. They consist of alkoxylated, predominantly unbranched fatty alcohols, and they contain higher alkene oxides alongside ethylene oxide. The fatty alcohol chains of some Plurafac® types terminate in an alkyl group. Their most important properties are wetting, low-foaming or even defoaming.


Dehypon® grades are fatty alcohol alkoxylates. The Dehypon® grades are oleochemical sourced. They are alkoxylated special grades which provide  very low foaming properties. The physical form vary from liquid to solid, even granules are available. Dehypon® grades are versatile useable and provide properties such as wetting, soil removal, low foaming and emulsification.


Low foaming surfactants are nonionic surfactants which are modified either by degree of alkoxylation or modified alkyl chain. The modification reduces the foam capacity. All low foaming surfactants are liquid, either 100% active or in a water diluted solution. The solubility of the low foaming surfactants increases in line with their cloud point. Products with a cloud point below room temperature can be made to form clear solutions by adding solubilizers such as alcohols or glycols.

Chemical-technical applications of our low foaming surfactants

Plurafac® and Dehypon® low foaming surfactants are used in versatile chemical-technical applications to ensure a smooth process flow. Application fields are besides others in the paper & pulp industry or in the metal treatment industry, especially in metalworking fluids. Also in the wood based fibre production, in textile pre-treatment and in coatings formulations BTC’s low foaming surfactants are used.
