Chemical Properties    sorbitan stearate has a bland odor and taste. It is a mixture of partial stearic and palmitic acid esters of sorbitol and its mono- and dianhydrides. For additional details of description, refer to Burdock (1997).
Uses sorbitan stearate is an emulsifier for water-in-oil creams and lotions, and a solubilizer of essential oils in water. It results from the reaction of stearic acid with sorbitol and is, therefore, synthetically produced from naturally derived materials.
Uses sorbitan stearate (Span 60) is a lipophilic emulsifier that is a sorbitan fatty acid ester, being a sorbitol-derived analog of glycerol monostearate. It is a nonionic, oil-dispersible surface-active agent. It is used as a gloss enhancer in chocolate coatings; as a dispersant aid in coffee whiteners; to increase volume in cakes and icings; and often in combination with polysorbates. Typical usage level ranges from 0.30 to 0.70%.
Uses Glycomul(R) L is a sorbitan ester used for emulsification.
Uses Glycomul(R) S KFG is used as emulsifier for baked goods, icings & filings and whipped toppings. It is also used as a rehydration aid (production of active dry yeast) and as synthetic flavoring substances and adjuvants. Product Data Sheet
Uses Lonzest(R) SMS is used as a pigment dispersion additive for PP color concentrates and as an antistatic agent for PVC.
Preparation    Prepared by reacting edible commercial stearic acid (usually containing associated fatty acids, chiefly palmitic) with sorbitol.
Safety Profile    Very mildly toxic by ingestion. Experimental reproductive effects. A skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes.

GENERAL DESCRIPTION & APPLICATIONS
Nonionic surfactants are surface active agents which do not dissociate into ions in aqueous solutions, unlike anionic surfactants which have a negative charge and cationic surfactants which have a positive charge in aqueous solution. Nonionic surfactants are more widely used as detergents than ionic surfactants because anionic surfactants are insoluble in many hard water and cationic surfactants are considered to be poor cleaners. In addition to detergency, nonionic surfactants show excellent solvency, low foam properties and chemical stability. It is thought that nonionic surfactants are mild on the skin even at high loadings and long-term exposure. The hydrophilic group of nonionic surfactants is a polymerized alkene oxide (water soluble polyether with 10 to 100 units length typically). They are prepared by polymerization of ethylene oxide, propylene oxide, and butylene oxide in the same molecule. Depending on the ratio and order of oxide addition, together with the number of carbon atoms which vary the chemical and physical properties, nonionic surfactant is used as a wetting agent, a detergent, or an emulsifier. Nonionic surfactants include alcohol ethoxylates, alkylphenol ethoxylates, phenol ethoxylates, amide ethoxylates, glyceride ethoxylates (soya bean oil and caster oil ethoxylates), fatty acid ethoxylates, and fatty amine ethoxylates. Another commercially significant nonionic surfactants are the alkyl glycosides in which the hydrophilic groups are sugars (polysaccharides).
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.
HLB numbers describe following characterestics:
<10 : Lipid soluble (or water-insoluble)
>10 : Water Soluble
4-8 : Antifoaming

GENERAL DESCRIPTION OF FATTY ACID
Fatty Acids are aliphatic carboxylic acid with varying length hydrocarbon chains at one end of the chain joined to terminal carboxyl (-COOH) group at the other end. The general formula is CnH2n+1COOH or R-(CH2)n-COOH. Fatty acids are predominantly unbranched and those with even numbers of carbon atoms between 12 and 22 carbons long react with glycerol to form lipids (fat-soluble components of living cells) in plants, animals, and microorganisms. Fatty acids all have common names respectively lilk lauric (C12), MyrIstic (C14), palmitic (C16), stearic (C18), oleic (C18, unsaturated), and linoleic (C18, polyunsaturated) acids. The saturated fatty acids have no double bonds, while oleic acid is an unsaturated fatty acid has one double bond (also described as olefinic) and polyunsaturated fatty acids like linolenic acid contain two or more double bonds. Lauric acid (also called Dodecanoic acid) is the main acid in coconut oil (45 - 50 percent) and palm kernel oil (45 - 55 percent). Nutmeg butter is rich in myristic acid (also called Tetradecanoic acid ) which constitutes 60-75 percent of the fatty-acid content. Palmitic acid(also called Hexadecylic acid ) constitutes between 20 and 30 percent of most animal fats and is also an important constituent of most vegetable fats (35 - 45 percent of palm oil). Stearic acid ( also called Octadecanoic Acid)  is nature's most common long-chain fatty acids, derived from animal and vegetable fats. It is widely used as a lubricant and as an additive in industrial preparations. It is used in the manufacture of metallic stearates, pharmaceuticals, soaps, cosmetics, and food packaging. It is also used as a softener, accelerator activator and dispersing agent in rubbers. Oleic acid (also called octadecenoic acid) is the most abundant of the unsaturated fatty acids in nature.

Therapeutic Uses    sorbitan stearate The formulation and characterization of a novel anhydrous organogel formulated as a potential delivery vehicle from a solution of 2 nonionic surfactants, sorbitan stearate (Span 60) and polysorbate 20 (polyoxyethylene sorbitan monolaurate; Tween 20), in hexadecane at 60DGC, which cools to a white, semi-solid, thermoreversible gel at room temperature, are described. The addition of an aqueous phase (water or niosome suspensions) up to 17% v/v to the oil phase at 60DGC produced water-in-oil and vesicle-in-water-in-oil systems, respectively. The release rate of hydrophilic solute from these gels was found to be lowest when a disperse system of spherical water droplets in the continuous oil phase was formed at high temperatures, compared to the faster release from the gel where the fibril structures acted as nearly continuous aqueous channels running through the organic medium, providing a means of traversing the oil phase.

Evidence for Carcinogenicity  Sorbitan stearate
Not classifiable as a human carcinogen. /Stearates; does not include stearates of toxic metals/
Sorbitan stearate increased gastric motility in two individuals given high single oral doses. Some indication of weak skin sensitization potential has been observed in man.
In rabbits, sorbitan stearate was irritant when applied repeatedly to the skin. It was of low acute oral toxicity to rats and repeated oral administration affected the kidney, liver and blood of rats and mice, and induced gastrointestinal disturbances in dogs and hamsters. Reproduction and foetal development were apparently unaffected in rats treated orally although offspring survival was reduced at doses which were probably maternally toxic. There was no evidence of carcinogenic potential in rats and mice given sorbitan stearate orally. No genotoxic potential was seen in mammalian cells treated in culture or in bacterial tests (including an Ames assay).
What Is It Sorbitan Stearate ?
Sorbitan Stearate, Sorbitan Laurate, Sorbitan Sesquioleate, Sorbitan Oleate, Sorbitan Tristearate, Sorbitan Palmitate and Sorbitan Trioleate are white to tan-colored solids. In cosmetics and personal care products, Sorbitan Esters are used in a variety of products including skin care products, skin cleansing products, moisturizers, eye makeup and other makeup.
Why is Sorbitan Stearate used in cosmetics and personal care products?
Sorbitan Stearate, Sorbitan Laurate, Sorbitan Sesquioleate, Sorbitan Oleate, Sorbitan Tristearate, Sorbitan Palmitate and Sorbitan Trioleate function as surfactant - emulsifying agents.
A popular, vegetable-derived oil-loving emulsifier that helps water to mix with oil. In itself, sorbitan stearate is suitable for water-in-oil emulsions (where water droplets are dispersed in oil), but sorbitan stearate is more often used as a co-emulsifier next to other, water-loving emulsifiers. 
Chemically speaking, sorbitan stearate comes from the attachment of sorbitan (a dehydrated sorbitol (sugar) molecule) with the fatty acid Stearic Acid, that creates a partly water (the sorbitan part) and partly oil soluble (stearic part) molecule. 
sorbitan stearate is functions of fragrance ingredient, surfactant - emulsifying agent, and emulsifying. Sorbitan stearate is a surfactant composed of sweetener sorbitol and stearic acid, a naturally occurring fatty acid.

Sorbitan stearate has a bland odor and taste. It is a mixture of partial stearic and palmitic acid esters of sorbitol and its mono- and dianhydrides. For additional details of description, refer to Burdock (1997). sorbitan stearate is an emulsifier for water-in-oil creams and lotions, and a solubilizer of essential oils in water. It results from the reaction of stearic acid with sorbitol and is, therefore, synthetically produced from naturally derived materials. Sorbitan stearate (Span 60) is a lipophilic emulsifier that is a sorbitan fatty acid ester, being a sorbitol-derived analog of glycerol monostearate. It is a nonionic, oil-dispersible surface-active agent. It is used as a gloss enhancer in chocolate coatings; as a dispersant aid in coffee whiteners; to increase volume in cakes and icings; and often in combination with polysorbates. Typical usage level ranges from 0.30 to 0.70%.
