COSMOGEL® 942V
COSMOGEL™ 942V is a cross-linked polymer of polyacrylic acid, used widely in personal care for its safety and versatility. COSMOGEL 942V is pH-sensitive, upon dissolution and neutralization it makes sparkling clear gels.

Applications
COSMOGEL 942V solution is characterized by high viscosity and clarity. It is very suitable for the preparation of sparkling clear gels as well as for stabilizing emulsions. It is also used to thicken some surfactant systems, and is excellent for suspending heavy particles. COSMOGEL™ 942V must be thoroughly mixed and hydrated. Increasing the pH to over 6.0, gives a gel structure. Neutralization can be carried out with inorganic bases such as NaOH, KOH or triethanolamine (TEA). Normal percentage of use is between 0.1 - 1.5% depending on type of formulation and final desired viscosity. USE COSMOGEL™ 942V is dispersed into water and neutralized with an appropriate base, a clear gel is formed. Dispersion should be made by slow addition of the polymer in order to avoid the formation of lumps and stirring until all particles are completely hydrated. Turbulent agitation should be avoided to prevent trapping of air which would be difficult to remove from the finished product. COSMOGEL 942V can be dispersed also in the oil phase obtaining free flowing dispersions with concentration over 30%. COSMOGEL 942V neutralization can be carried out with inorganic bases (such as NaOH, KOH, NH4OH) or with organic amines such as (TEA, AMP, AMPD). It is advisable to add strong bases previously diluted into water at a concentration not higher than 10%. inorganic bivalent bases must be avoided because a ionic cross-link can occur causing precipitation of the polymer.
Packaging
COSMOGEL™ 942V is packed in boxes of 20 kg on shrink wrapped pallets of 400 kg net.
