• Personal care: emollient, spreading agent and carrier fluid in skin creams, color cosmetics and hair conditioners
• Metalworking and industrial lubrication: base fluid or additive in cutting oils and release agents that reduces friction and wear
• Plastics processing: external lubricant and plasticizer for PVC and other polymers, improving flow during extrusion
• It also serves as a solvent and carrier for pigment dispersions and active ingredients in cosmetic and industrial coatings.
