ROKAfenol N40/70 is a non-ionic surfactant belonging to the group of ethoxylated nonylphenols. INCI Name: Nonoxynol-40. It is a liquid with a colour of up to 100 HU. The content of the active substance in the commercial product is about 70%. The product has good water solubility. It has a cloud point within the temperature range of 73-79°C in a solution of NaCl 100 g/L and solidifies at a temperature of about 0°C.
ROKAfenol N40/70 is a component of washing and cleaning agents and laundry detergents. It acts as an emulsifier and dispersant, thus improving detergency properties. ROKAfenol N40/70 can be mixed with other non-ionic auxiliaries and with anionic and cationic agents. Moreover, it is characterized by good resistance to oxidizing and reducing factors, as well as stability in acids and alkalis.
ROKAfenol N40/70 is suitable as a non-ionic emulsifier in the emulsion polymerization process. The highest effectiveness of the agent is achieved in combination with a suitable anionic surfactant (e.g. ROSULfan L, ABSNa, SULFOROKAnol L225/1), which provides control over the reaction parameters. High degree of ethoxylation, and thus high hydrophilicity, ensures excellent stability of polymer dispersion in the environment of electrolytes (including hard water) and organic solvents. ROKAfenol N40/70 is compatible with a wide range of polymers and can be used in the production of acrylic, styrene-acrylic, homo- and copolymers of vinyl acetate dispersions. Typical application of the product is 0.5-3% by total dispersion weight.
ROKAfenol N40 / 70 is also used as an emulsifier for the production of bituminous masses and for the emulsification of asphalts. It is also an emulsifying additive in the production of polyester resins.
