Sorbitan Sesquioleate. May Contain Iron Oxides/Ci 77492 ●
TL;DR. It is a low-HLB nonionic emulsifier, co-emulsifier, and pigment-wetting dispersant, especially useful in water-in-oil, oil-rich, and anhydrous color formulas. It helps oils, waxes, powders, and the optional yellow mineral pigment stay evenly distributed.
What does Sorbitan Sesquioleate. May Contain Iron Oxides/Ci 77492 do in a cosmetic formula?
It is a low-HLB nonionic emulsifier, co-emulsifier, and pigment-wetting dispersant, especially useful in water-in-oil, oil-rich, and anhydrous color formulas. It helps oils, waxes, powders, and the optional yellow mineral pigment stay evenly distributed.
Is Sorbitan Sesquioleate. May Contain Iron Oxides/Ci 77492 clean?
Clean frameworks generally treat it as acceptable because it is non-ethoxylated and typically used at low levels, though it has an uncommon contact-allergy profile in leave-on products. The optional mineral colorant is generally accepted when purity limits for heavy metals are met.
Is Sorbitan Sesquioleate. May Contain Iron Oxides/Ci 77492 sustainable?
This material is commonly made from plant-derived sugar alcohols and fatty acids, with sourcing dependent on crops such as palm, rapeseed, sunflower, or olive. It is biodegradable, while the optional mineral pigment is inert and non-biodegradable but not considered environmentally persistent in the same way as synthetic polymers.
Is Sorbitan Sesquioleate. May Contain Iron Oxides/Ci 77492 COSMOS-approved?
It is generally permitted under COSMOS-natural and can be used in COSMOS-organic formulas when feedstocks and processing meet the standard. It fits Green Chemistry principles best when made from renewable feedstocks through simple esterification, with good biodegradability and low formulation burden.
How does Sorbitan Sesquioleate. May Contain Iron Oxides/Ci 77492 work chemically?
The molecule is a mixture of mono- and di-esters formed from a cyclic sugar-alcohol derivative and unsaturated C18 fatty acids, giving an oil-soluble, nonionic surfactant with an HLB around 3 to 4. Typical use is about 0.5 to 5% as a co-emulsifier or dispersant, with broad pH tolerance because it is nonionic, while the unsaturated chains can slowly oxidize unless the formula includes antioxidant support.
