Oleochemicals & Surfactants: Soft Soap Base

Primary precursor for Sodium Oleate and Potassium Oleate. These "soft soaps" are highly soluble in water and provide excellent detergency without the harshness of saturated fats. Used to produce Sorbitan Oleates (Spans) and Polysorbate 80, the industry standards for stabilizing oil-in-water emulsions

Metallurgy & Mining: Flotation & Lubrication

In the mining industry, Used collector for froth flotation facilitates the separation of minerals like haematite and fluorite. In metalworking, serves as a high-lubricity additive for cutting oils and drawing compounds, reducing friction and heat during high-speed machining

Pharmaceuticals: Penetration Enhancement

Utilised as a penetration enhancer in topical and transdermal drug delivery. Its "kinked" molecular structure temporarily disrupts the skin's lipid barrier, allowing (APIs) to move more freely through the stratum corneum into the bloodstream

Storage Stability

Sensitive to air and light. Oxidation (rancidity) can occur due to the double bond, leading to a darker color and sharp odor

Storage Section

Store in a cool, dry place (below 25°C). For bulk storage, Stainless Steel (316L) or lined tanks are required. Maintain a Nitrogen Blanket to prevent oxidation.

Shipping

Non-hazardous for transport. Available in 190kg steel/plastic drums, 950kg IBC totes, or ISO Tanks for large-volume global distribution.
