Chemical Properties
Pale yellow or slightly brownish-yellow paste, which becomes a viscous, oily, brownish-yellow liquid at about 25 °C.

Uses
sorbitan sesquioleate is a surfactant used as an emulsifying agent.

Uses
Sorbitan sesquioleate is used as an emulsifier in cosmetic and pharmaceutical ointments and creams.

Sorbitan sesquioleate is useful as a stabilizing agent in polymerization process to produce spherical acrylamide beads.[2] It has been used in many topical agents. SSO have recently been implicated in allergic dermatitis.

A mainly oil loving molecule that helps water and oil to mix nicely, aka emulsifier. In itself, it can create water-in-oil emulsions (when water droplets are dispersed in oil), but it is used mostly next to water-loving emulsifiers to create nice and smooth oil-in-water creams. It can also function as a wetting and dispersing agent helping insoluble particles such as color pigments or inorganic sunscreens (zinc/titanium dioxide) to disperse nice and even in liquids.

Chemically speaking, this molecule is "halfway" between Sorbitan Oleate and Sorbitan Trioleate, meaning that it is also an attachment of sorbitan (a dehydrated sorbitol (sugar) molecule) with the unsaturated fatty acid Oleic Acid, but in a ratio of 2:3 hence the "Sesqui" part in the molecule's name.

Uses
This medication is used as a moisturizer to treat or prevent dry, rough, scaly, itchy skin and minor skin irritations (e.g., diaper rash, skin burns from radiation therapy). Emollients are substances that soften and moisturize the skin and decrease itching and flaking. Some products (e.g., zinc oxide, white petrolatum) are used mostly to protect the skin against irritation (e.g., from wetness).Dry skin is caused by a loss of water in the upper layer of the skin. Emollients/moisturizers work by forming an oily layer on the top of the skin that traps water in the skin. Petrolatum, lanolin, mineral oil and dimethicone are common emollients. Humectants, including glycerin, lecithin, and propylene glycol, draw water into the outer layer of skin. Many products also have ingredients that soften the horny substance (keratin) that holds the top layer of skin cells together (including urea, alpha hydroxy acids such as lactic/citric/glycolic acid, and allantoin). This helps the dead skin cells fall off, helps the skin keep in more water, and leaves the skin feeling smoother and softer.

Sorbitol-based emulsifiers such as sorbitan sesquioleate (SSO) are commonly used in topical corticosteroids, topical antibiotics, topical antifungals, moisturizing creams and lotions, and topical retinoids.

Sorbitan sesquioleate is an essential ingredient in many lotions and other skin-care products. It acts as a humectant to bind moisture, thicken the product, and stabilize the mixture of water and oils. This stabilization effect is why Sorbitan sesquioleate is known as an emulsifier — it allows two liquids, which normally would not blend, to form a stable mix called an emulsion. Many everyday products use this to keep a cream base from breaking apart during long-term storage in vials, jars, and bottles. Separation may still occur, however, when products are subjected to extreme hot or cold temperatures.

The source of Sorbitan sesquioleate is berries and other vegetable matter. The compound is derived as a natural alcohol, combining a sugar alcohol called sorbitol with fatty acids from vegetables. Sorbitol can be found in natural sources such as corn, plums, and many other common foods. When the sorbitol and fatty acids react, they create a new compound that retains the humectifying properties of sorbitol, and makes the alcohol an effective skin moisturizer and softener. This is why it is often used in anti-aging formulas, rash treatment creams, and dry skin treatments. The moisturizing properties are also useful in sunscreen lotions and creams.

The compound is also used in some cosmetics. Sorbitan sesquioleate can act as a binding agent for cream-based cosmetics, such as cream eyeshadow or liquid foundation. It can also act as a moisturizing agent to reduce the dehydrating effects caused by repeated use of some cosmetics, and to reduce skin flaking caused by wearing makeup over long periods of time. Lotion-based medical treatments and salves, such as athlete's foot medications, may also include some form of sorbitol-based emulsifier.

Sorbitan sesquioleate has a low risk of allergic reaction and is generally considered a gentle substance, safe for topical use. Some users have reported skin reactions, including irritation, redness, and hives. These reactions are usually mild, rare, and treatable by conventional methods. Many baby products use the compound, and little to no adverse effect has been reported on infant skin.

The Environment Canada Domestic Substance List has raised concerns about Sorbitan sesquioleate as a possible environmental toxin. Many cosmetic products identify the compound as an environmentally-safe plant emulsifier, however. Other, non-naturally derived stearates may pose issues with water pollution or environmental toxicity — such as glycol stearate, which combines natural stearate alcohols with toxic ethylene glycol to produce sheened, pearl-like textures in products like shampoos.

Features and benefits:
Liquid and easy to handle
Good environmental & health profile
Highly efficient emulsification
Allows high loading of pigments/fillers
Low foaming; absence of surface defects

Sorbitan sesquioleate is an sorbitan ester chosen for its suitability as a guar slurry aid. Sorbitan sesquioleate allows for quick hydration of guar slurries and increases stability. It is FDA approved for use in indirect food contact applications and is highly effective in a wide range of formulations. Sorbitan sesquioleate is also used as an emulsifier, creating stable water/oil emulsions. Croda’s Span range of emulsifiers can be produced from a variety of feedstocks to diverse specifications and requirements, including peroxide free or reduction/oxidation friendly emulsifiers.

Sorbitol is a white, sweetish, hygroscopic, crystalline sugar alcohol of six-carbon. It is found naturally in various berries and fruits. Or it is prepared synthetically by high-pressure catalytic hydrogenation of glucose sugar derived from cornstarch. It melts at 93 to 98 C depending on the form. It is used as a a sweetening agent, food additive, toothpaste, tobacco, toiletries and in cosmetics. It is used for vitamin-C fermentation. It is used as a excipient and intravenous osmotic diuretic in pharmaceutical fields. It is also used in the manufacture of polyethers for polyurethanes and surfactants. The term sorbitan describes the anhydride form of sorbitol, whose fatty acids are lipophilic whereas sorbitol body is hydrophilic. This bifunctionality in one molecule provides the basic properties useful in cleaners, detergents, polymer additives, and textile industry as emulsifiers, wetting agents, and viscosity modifiers. Sorbitan esters are rather lipophilic (or hydrophobic) surfactants exhibiting low HLB (Hydrophilic-Lipophilic Balance) values; having an affinity for, tending to combine with, or capable of dissolving in lipids (or water-insoluble). While, the ethoxylated sorbitan esters are hydrophilics exhibiting high HLB values; having an affinity for water; readily absorbing or dissolving in water. The type of fatty acid and the mole number of ethylene oxide provides diverse HLB values for proper applications.

Sorbitan Sesquioleate is w/o emulsifier, particularly recommended for unsaturated lipid components such as oleyl alcohol or vegetable oils. Dispersing agent for insoluble liquids in other lipophilic liquids. Used as wetting agent and dispersant for pigments in color cosmetics and zinc oxide/titanium dioxide in sun care products.

Sorbitan sesquioleate (SSO) has been added to fragrance mix I (FM I) as an emulsifier since the 1990s. Being a contact allergen itself, SSO has the potential to cause false-positive reactions to FM I. Recent results obtained with selected FM I-positive patients have shown that 5% have concomitant positive reactions to SSO.
