Acrypol range is a synthetic high molecular weight cross linked water soluble polymer of acrylic acid, which is known as "Carbomer". It is widely used in cosmetic, pharmaceutical and household industries.
It is available in powder and liquid form, which is soluble in water, alcohols and glycols. Before neutralization, pH of Acrypol grade solution lies between 2.5 and 3.0.
General Application
Thickening - To produce wide range of viscosities and flow properties
Suspending - Insoluble ingredients
Stabilizing - Emulsion

*Viscosity of neutralized solutions is to be measured at 25°C and 20 rpm.
- Thickening efficiency High viscosity at low concentration
- Uniform performance Carbomer gives uniform viscosity performance, while natural gums vary in their performance
- Temperature Stability There is no significant effect of temperature on polymer
- Unaffected by aging Excellent shelf life
- Microbial Resistance Resists bacterial attack and does not support mould growth
- Versatility Although primarily used in aqueous systems with neutralization, it can also be used in solvent systems, with or without neutralization
- Elegance Smooth and luxurious feeling
Toxicity
Acrypol range is a high molecular weight polymer. It cannot be absorbed by body, thus it is totally safe for human consumption. Test for toxicological tolerance shows that it does not have any pronounced, physiological action and is non-toxic.
Dermal irritation (in vitro test) - non irritant
Eye irritation (in vitro test) - non irritant
Skin sensitization (max. test) - non sensitizing
Storage & Handling
Acrypol range is highly hygroscopic in supplied form, it contains maximum of 2.0% moisture. When exposed to open air at room temperature and 50% relative humidity, its equilibrium moisture uptake is 8.0%. All moisture uptake does not affect its efficiency but polymer with high level of moisture is more difficult to disperse and weigh accurately. So, Acrypol polymers must be stored in a tightly closed container and away from direct contact with water and excessive humid conditions.
Acrypol polymer's efficiency will not get affected up to two hours at temperatures below 104°C. When it is exposed to excessive temperatures, it can be plasticized and lose its characteristics.
Shelf life
Powder form - Five years from date of manufacturing in intact condition
Liquid form - One year from date of manufacturing in intact condition
Note: Based on our testing, dry Acrypol polymers should last for years if stored properly and protected from moisture and extreme temperature
Packing
Powder form - 20 kg net in corrugated box with polyethylene liner
Liquid form - 50 kg plastic carboys and 200 kg plastic drum
