RADIACID 0908

CAS: 30399-84-9
IUPAC Name: 16-methylheptadecanoic acid

Chemical Name: Isostearic acids
Molecular Formula: C18H36O2

Radiacid fatty acids are emollients, bodying agents, stabilizers and binders.
Their main application however is the production of soaps: luxury soaps, shaving sticks and emulsifying soaps.

Radiacid 0908 is derived from 100% vegetable origin.
Due to their branched structure the isostearic acid has a characteristic emollient feel: a non-greasy after feel, a highly substantive lipid film, soft skin feel and leave a glossy appearance to the skin.

Isostearic acid is derived from natural oils and differentiated from many other branched fatty acids by its methyl-branching.
These kind of methyl-branched fatty acids and alcohols are often found in nature as protection for aquatic birds whom use these ‘waxes’ to keep the feathers in optimal condition and be protected against climatic conditions.
The branched isostearic esters are known as liquid lipids and are widely used in cosmetic and personal wash applications where they provide good spreading, non-tacky and pleasant skin feel.
An important advantage of using the isostearic acid and derivatives over the corresponding oleic acid and derivatives is the low iodine value, due to the absence of the unsaturation.
This guarantees oxidative stability and thus the usage in eg perfume and preservative free systems without concern for rancidity.

16-methylheptadecanoic acid is a methyl-branched fatty acid that is heptadecanoic acid (margaric acid) substituted by a methyl group at position 16.
16-methylheptadecanoic acid is a branched-chain saturated fatty acid, a long-chain fatty acid and a methyl-branched fatty acid.
16-methylheptadecanoic acid derives from a heptadecanoic acid.

Radiacid 0908 serves as a smooth, dry feeling emollient able to assist the skin in replenishing its natural moisture.
Also, Isostearic Acid when neutralized serves as an extremely effective and stable co-emulsifier used in the preparation of oil in water, low viscosity emulsion systems.
When incorporated in a formulation in place of stearic acid, it reduces the fatty feel to a non-fatty feel.
Isostearic Acids applications include skin creams, lotions, moisturizing creams, color cosmetics, sunscreen preparations, and shower gel formulations.

Isostearic acid is a fatty acid molecule with an 18-carbon atom chain backbone.
Isostearic acid is an isomer of stearic acid, meaning that they both have a chemical formula of C18H36O2, but differ in the arrangement of their atoms.
While stearic acid has a linear carbon chain with 18 carbon atoms, isosteric acid as a carbon chain with 17 atoms and a single carbon branch at the 16th carbon atom.
Isostearic acids chemical structure can be represented as (CH3)2CH(CH2)14CO2H.
Isostearic acid is found naturally in meat products and vegetable oils.

Isostearic acid has a wide range of industrial uses.
Isostearic acid is mainly used as an additive in adhesives or lubricants for both paints and personal care products.
