Chemistry Low foam surfactant

2 of 3 products in this range

Alkali stable surfactant

Alkali-stable surfactants maintain performance in high-pH systems (typically pH 10–14)—essential for heavy-duty liquid detergents, caustic cleaners, institutional degreasers, and textile scouring under alkaline conditions.

Anionic alkali-stable grades

T-Mulz 66H is the potassium salt of a blended anionic phosphate ester with good solubility in high-alkaline liquids. It hydrotropes nonionic surfactants into alkaline detergents while contributing detergency and wetting. See anionic surfactants and phosphate esters guide.

Nonionic caustic-stable grades

T-DET® CSLF-17 is a nonionic, low-foaming fatty alcohol EO/PO glycol end-capped as monobenzyl ether (CAS 9003-11-6). It is caustic stable, readily biodegradable, and used in food and dairy cleaners, machine dishwash, metal cleaners, pulp and paper, and rinse-aid formulations.

Applications

Alkali-stable surfactants serve HI&I cleaning, metal cleaning, textile processing, and agrochemical formulations. Contact Venus for alkali stability data and samples.

Surfactants (surface-active agents) reduce surface tension between liquids or a liquid and a solid. They have hydrophilic and hydrophobic parts and act as emulsifiers, detergents, wetting agents, and dispersants.

Venus Ethoxyethers Pvt. Ltd. manufactures surfactants in India: non-ionic, anionic, cationic, and amphoteric. We supply ethoxylates, sulfates, sulfosuccinates, and specialty surfactants from our Goa facility.

Non-ionic surfactants have no charge and are compatible with all types. Anionic have a negative charge and are excellent for cleaning. Cationic have a positive charge for conditioning and antimicrobial use. Amphoteric can have both charges depending on pH.

The best surfactant depends on application, pH, compatibility, and desired properties. Our technical team can recommend the right surfactant for your formulation. Contact us for samples and support.
