Description

Carbopol 940 is a high molecular weight, cross-linked polyacrylic acid polymer that appears as a white, fluffy powder and is widely used for its thickening, suspending, and stabilizing properties. It is soluble in water and forms clear, high-viscosity gels upon neutralization within a pH range of 5 to 8. The polymer is highly efficient even at low concentrations and is compatible with a broad range of ingredients, making it ideal for use in cosmetics and pharmaceutical formulations such as gels, creams, and lotions.

Carbopol 940 Basic Attributes

Molecular Weight：

72.063

Exact Mass：

72.021

EC Number：

618-347-7

Characteristics

PSA：

37.3

XLogP3：

0.36 (estimated)

Appearance：

Acrylic acid is a colorless liquid with a distinctive acrid odor. Flash point 130°F. Boiling point 286°F. Freezing point 53°F. Corrosive to metals and tissue. Prolonged exposure to fire or heat can cause polymerization. If polymerization takes place in a closed container, violent rupture may occur. The inhibitor (usually hydroquinone) greatly reduces the tendency to polymerize.

1.05

Melting Point：

55°F

Boiling Point：

286°F

Flash Point：

121°F

Water Solubility：

Miscible

Storage Conditions：

Excessive dust generation should be minimized to avoid the risk of explosion (lowest explosion concentration is 130 g/cu m).

Vapor Pressure：

Vapour pressure, Pa at 20°C: 413

Vapor Density：

Relative vapour density (air = 1): 2.5

Flammability characteristics：

Class II Combustible Liquid: Fl.P. at or above 100°F and below 140°F.

Explosive limit：

vol% in air: 3.99.8

Odor：

Acrid odor and fumes

PH：

pH = 3 (approximately)

Storage features：

Fireproof. Separated from strong oxidants, strong bases, strong acids and food and feedstuffs. Keep in the dark. Store only if stabilized. Store in an area without drain or sewer access. Storage conditions may vary according to the type of inhibitor used. Refer to the manufacturer's instructions for proper storage conditions. See Notes.

Stability/Shelf Life：

Carbomers are discolored by resorcinol and are incompatible with phenol, cationic polymers, strong acids, and high levels of electrolytes. Certain antimicrobial adjuvants should also be avoided or used at low levels. Trace levels of iron and other transition metals can catalytically degrade carbomer dispersions. Certain amino-functional actives form complexes with carbomer Carbomers also form pH-dependent complexes with certain polymeric excipients.
