Used primarily as a plasticizer and intermediate in the synthesis of specialty esters for lubricants and cosmetics. Its branched-chain structure provides excellent low-temperature performance and oxidative stability in synthetic lubricants. Commonly found in skin care formulations due to its emollient properties, it helps improve texture and spreadability while reducing greasiness. Also serves as a solvent or carrier for fragrances and active ingredients in personal care products. Its hydrophobic nature enhances water resistance in cosmetic applications such as sunscreens and makeup.
