Plant-based isostearic acid and derivatives are a class of branched-chain C18 fatty acids and their functionalized products prepared from renewable vegetable oils using green chemical processes. Its core molecule, isostearic acid (CAS: 30399-84-9), is a methyl branched fatty acid obtained through the catalytic hydrogenation-skeletal isomerization reaction of natural unsaturated fatty acids (such as oleic acid and ricinoleic acid). Unlike petrochemical-based synthetic fatty acids, it has 100% bio-based carbon content (tested according to ASTM D6866 standard). These derivatives include free isostearic acid, isostearates (such as isostearyl isostearate and polyglycerol isostearate), isostearates, and isostearamides, which are widely used in cosmetics, personal care, lubricants, plasticizers, and textile auxiliaries, aligning with the global trends of "carbon neutrality" and "green chemistry."

The raw material system for plant-based isostearic acid and its derivatives relies entirely on renewable vegetable oil resources. Core raw materials include castor oil (India accounts for over 90% of global production and is rich in ricinoleic acid), high-oleic sunflower oil (Europe), palm oil (Southeast Asia), rapeseed oil (Canada and Europe), and soybean oil (Americas). The production process employs green catalytic technology: first, the vegetable oil is selectively hydrogenated using a nickel-based or precious metal catalyst; then, skeletal isomerization is performed on a solid acid catalyst (such as a molecular sieve) to convert straight-chain unsaturated fatty acids into methyl-branched isostearic acid; finally, it is purified to the desired specifications through molecular distillation. Advanced processes have achieved a bio-based carbon content >95% (ASTM D6866 testing) and passed ISO 16128 Natural Source Index certification.

Regarding cost structure, raw material costs account for 60-75% of total costs and are subject to multiple factors: castor oil prices are unstable due to fluctuations in Indian export policies and monsoon climates; palm oil prices are affected by RSPO sustainability certification and Southeast Asian production fluctuations; to obtain high bio-based content certification, companies need to establish a traceable sustainable supply chain, increasing procurement costs by 15-25%.
