Isostearic Acid is a branched-chain saturated fatty acid widely used as a functional ingredient in cosmetic and personal-care formulations. Unlike straight-chain Stearic Acid, Isostearic Acid has a branched molecular structure, which gives it different physical and formulation characteristics.
Isostearic Acid is valued in cosmetic formulations for its emollient, skin-conditioning, dispersing, pigment-wetting and texture-modifying properties. Its liquid nature at room temperature makes it particularly useful in formulations where a liquid fatty-acid component is preferred over higher-melting straight-chain fatty acids.
It is commonly used in creams, lotions, color cosmetics, makeup products, sunscreens, facial oils, lip products and other anhydrous or emulsion-based personal-care formulations.
Because Isostearic Acid is generally produced as a mixture of branched-chain C18 fatty acids rather than a single pure molecular isomer, its exact composition and specification can vary according to manufacturing process and grade.
Isostearic Acid is a collective term generally used for branched-chain C18 saturated fatty acids, commonly derived through processes such as the isomerization of oleic acid.
Unlike Stearic Acid, which has a straight C18 chain, Isostearic Acid has branching in its hydrocarbon chain. This branching contributes to its lower melting behavior and improved fluidity.
Key characteristics include:
Isostearic Acid is a versatile cosmetic fatty-acid ingredient that can contribute to both formulation performance and sensory characteristics.
Potential functions include:
Potential applications include:
Isostearic Acid can provide an emollient and conditioning component in suitable skincare formulations.
Potential applications include:
Its branched structure can provide a different sensory and spreading profile compared with straight-chain saturated fatty acids.
Isostearic Acid is particularly useful in selected color-cosmetic formulations because it can assist with pigment wetting and dispersion.
Potential applications include:
It can help formulate oil-phase systems where good pigment incorporation and suitable texture are required.
Isostearic Acid can be incorporated into selected sunscreen and sun-care formulations as an emollient and oil-phase ingredient.
Potential functions include:
Compatibility with UV filters and the complete formulation should be evaluated during product development.
Important formulation considerations include:
Because commercial Isostearic Acid can represent a mixture of branched-chain fatty acids, the fatty-acid profile and grade-specific specification are important when selecting material for a particular formulation.
