Emulsifiers for Skin Care Applications

Emulsifiers for W/O Emulsions
Despite the fact that oil-in-water emulsions still dominate the cosmetic market, water-in-oil emulsions are favored when a greater
emolliency is desired in Night Creams, Nappy/Diaper Rash emulsions or All Weather Creams.

Organosilicone emulsifiers
• ABIL ® EM 90 (Cetyl PEG/PPG-10/1 Dimethicone)
• ABIL ® WE 09 (Polyglyceryl-4 Isostearate, Cetyl PEG/PPG-10/1 Dimethicone, Hexyl Laurate)
• ABIL ® EM 97 (Bis-PEG/PPG-14/14 Dimethicone, Cyclopentasiloxane)
The excellent stabilizing potential of the polymeric and polyfunctional organosilicone emulsifiers combined with their specific
application properties (excellent spreading and film forming, skin feel) gives them an essential role in many cosmetic formulations.
ABIL ® EM 90 and ABIL ® WE 09 are suitable for the preparation of Multiple Emulsions of the water-in-oil-in-water (W/O/W) type
or the oil-in-water-in-oil (O/W/O) type. One of the most interesting possibilities of these triple emulsions is the gradual release of
water-soluble or oil-soluble active ingredients from the internal phase.
Vegetable based, PEG-free emulsifiers
• ISOLAN ® PDI (Diisostearoyl Polyglyceryl-3 Dimer Dilinoleate)
• ISOLAN ® GI 34 (Polyglyceryl-4 Isostearate)
• ISOLAN ® GPS (Polyglyceryl-4 Diisostearate/Polyhydroxystearate/Sebacate)
The importance of natural, PEG-free raw materials for skin care cosmetics has strongly increased. Poly gly cerol esters and glucose
esters of natural fatty acids are the emulsifiers of choice for W/O emulsions when good application properties linked with high
temperature stability and flexibility of phase-volume ratio is afforded. ISOLAN ® GI 34 is especially suitable for W/O creams. The
well-known emulsifier ISOLAN ® PDI is used in a wide range of applications such as creams and lotions in Skin Care. ISOLAN ® GPS
is especially designed for the formulation of low viscous W/O lotions with very low oil phase content (down to 18 – 20%).
