Sorbitan Sesquioleate is a nonionic surfactant derived from sorbitol and oleic acid, with a 1.5:1 fatty acid-to-sorbitan ratio ("sesqui-"). It has a low HLB (~3.7), making it oil-soluble and ideal for stabilizing water-in-oil (W/O) emulsions. Widely used in cosmetics (creams, sunscreens), food (as emulsifier E495), and pharmaceuticals (ointments), it enhances texture, reduces greasiness, and improves spreadability. Approved by the FDA and EU for regulated applications, it is biodegradable and low-irritation but requires controlled use in sensitive formulations.
Sorbitan Sesquioleate is a nonionic surfactant and emulsifier derived from sorbitol (a sugar alcohol) and oleic acid (a monounsaturated fatty acid). Here’s a structured overview:
Structure: Composed of sorbitol (dehydrated to sorbitan) esterified with approximately 1.5 oleic acid molecules per sorbitan unit ("sesqui-" denotes a 1.5:1 ratio).
HLB Value: ~3.7, classifying it as a lipophilic (oil-soluble) emulsifier, ideal for water-in-oil (W/O) emulsions.
Appearance: Yellow to amber viscous liquid.
Solubility: Insoluble in water; soluble in oils and organic solvents.
Cosmetics & Personal Care:
Emulsifier: Stabilizes W/O formulations in creams, lotions, and sunscreens.
Texture Modifier: Enhances thickness and reduces greasiness in skincare products.
Emollient: Improves skin softness and spreadability.
Food Industry (regulated use):
Acts as an emulsifier (e.g., E495) in baked goods, chocolates, and processed foods.
Pharmaceuticals & Industrial:
Used in ointments to disperse active ingredients.
Functions as a lubricant or additive in coatings and agrochemicals.
Safety Profile:
Low irritation potential, widely used in cosmetics (avoid high concentrations on sensitive skin).
Approved by FDA (21 CFR 172.842) and EU (EC No 1333/2008) for limited food applications.
Environmental Impact: Biodegradable but requires controlled disposal.
vs. Sorbitan Monooleate (Span 80):
Span 80 has a higher HLB (~4.3) and lower oleic acid content, making it less lipophilic.
Sorbitan Sesquioleate’s higher oleic acid ratio improves stability in oil-rich formulations.
Skincare: Moisturizers, makeup removers.
Food: Chocolate coatings, margarine.
This versatile emulsifier balances cost-effectiveness and functionality in oil-dominant systems while meeting regulatory standards.
