We have developed Bis-beheyl/isostearyl/phytosteryl dimer dilinoleyl dimer dilinoleate (oligomer ester) as a novel plant-derived lanolin or adsorption refined lanolin substitute with very pale color (GH = 1), low odor, and excellent stability. It is an oligomer ester type phytosterol ester in a paste form synthesized only from plant-derived materials. This oligomer ester has excellent lanolin-like properties such as high water holding capability (200%), excellent moisturizing effect in human use tests excellent gloss in makeup products (superior to lanolin and adsorption refined lanolin) coming from its high refractive index (approx. 1.475 at 60 degrees C), high pigment dispersing ability, excellent foam-stabilizing ability and moisturizing effect in cleansing products and shampoos, emulsion stabilizing effect, skin affinity, e.t.c. And this oligomer ester is much more stable against oxidation than lanolin and adsorption refined lanolin in CDM test. So this oligomer ester is useful for make-up products, cleansing products, skincare products, and haircare products.
