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:

Chemical Properties

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.

Primary Applications

1. 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.

2. Food Industry (regulated use):

   Acts as an emulsifier (e.g., E495) in baked goods, chocolates, and processed foods.

3. Pharmaceuticals & Industrial:

   Used in ointments to disperse active ingredients.                                                                                                                                  Functions as a lubricant or additive in coatings and agrochemicals.

Safety & Regulation

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.

Key Differences from Similar Surfactants

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.

Example Products

Skincare: Moisturizers, makeup removers.

Food: Chocolate coatings, margarine.

This versatile emulsifier balances cost-effectiveness and functionality in oil-dominant systems while meeting regulatory standards.
