Applications
1. Yeast Protectant For Instant Dry Yeast: It is used as a protectant in instant dry yeast production, where it helps preserve cell viability through the drying step, and it also serves as an antifoam during yeast rehydration in industrial fermentation.
2. Lipophilic W/O Emulsifier With HLB 8.6: At an HLB near 8.6 it forms water in oil emulsions on its own and is commonly paired with its ethoxylated counterpart polysorbate 20 to build oil in water systems at a tuned blend HLB.
3. Food Additive Emulsifier E493: Authorised in the EU as sorbitan monolaurate under E493 and grouped with the sorbitan esters E491 to E495, it balances fat and water phases and controls dispersion in food and feed formulations.
4. Emulsifier And Stabiliser For Cosmetics: In creams and lotions it emulsifies and stabilises essential oils in water.
5. Industrial Wetting, Emulsifying And Defoaming: In textile, agrochemical, coating, lubricant and oilfield formulations it acts as a nonionic wetting agent and emulsifier, and it can be used as a defoaming agent where foam control is required.
