IMWITOR® 900 K by IOI Oleo is a non-ionic co-emulsifier for O/W emulsions. It is an ester of natural stearic and palmitic acid esterified with glycerol. It is 100% natural, vegan and compatible with skin. It does not contain additives, residues of antioxidants, stabilizers, solvents or unsaturated components. Because of surface-active properties, it functions as solubilizing and binding agent, dispersing adjuvants, softeners and consistency regulators. It is applicable for hot/cold and hot/hot processes. IMWITOR® 900 K finds application in formulating lotions, creams, powders, skin cleansing products, makeup bases and foundations, mascara, eye shadow, eyeliner, hair conditioners and sun care products. It is ECOCERT and COSMOS approved. It has a shelf life of 24 months.

IMWITOR® 988 is a partial ester of caprylic acid and glycerol. Fatty acids and glycerol are derived from vegetable sources.

​WITEPSOL® products of series W are hard fats with hydroxyl values of 20–50. They consist of a mixture of triglycerides (65–80%), diglycerides (10–35%), and monoglycerides (1–5%). As a result of their composition, these WITEPSOL® grades have a larger gap between melting and solidification points, they are less sensitive to shock cooling (more elastic), solidify more slowly, and can be readily processed both with automatic machines and with small-scale equipment. The partial glyceride content also slows down the sedimentation of solids and promotes the absorption of less readily absorbable active compounds.

WITEPSOL® W35 has a melting point 33.5–35.5°C and a hydroxyl value of 40–50 mg KOH/g
