About Polysorbate 40

The Polysorbates (comprising 20, 40, 60, and 80) are a series of non-ionic surfactants and emulsifiers derived from ethoxylated sorbitan esterified with fatty acids. Within the Food & Nutrition, Pharmaceutical, and BPC hierarchies, peg- the industry standard for stabilising O/W emulsions. While they share a common poly...

Appearance

Flakes

Industrial Coatings & Inks

Wetting agent and dispersant for pigments in water-borne paints. It helps the paint spread evenly on surfaces and prevents pigment clumping (flocculation)

Agrochemicals (Adjuvant Systems)

Concentrated herbicide and pesticide formulations to improve the "spreading" of the chemical on waxy leaf surfaces, ensuring better absorption of the active ingredient

Specialized Topicals

Pharmaceutical creams where a specific "mid-range" HLB is needed to balance oil-heavy medicated ointments with water-washable bases.

Stability

Stable under normal conditions. May undergo autoxidation if exposed to light or air for extended periods, leading to peroxide formation.

Storage Section

Store in a cool, dry place (15°C to 25°C). Keep containers tightly closed. Use amber glass or opaque HDPE to protect from light.

Shipping

Non-hazardous for transport. Available in 200kg drums, and 1000kg IBCs.
