Co-emulsifying stabilizing system

INCI name

Polyglyceryl-4 Oleyl Ether, Oleyl Phosphate


STABILGREEN® K is a new 100% natural (vegetable and mineral) “hydrophilic lipid” capable of stabilizing even the most difficult emulsions, making them particularly fresh and light and giving them a pleasant “velvety” effect.
STABILGREEN® K is an effective co-emulsifying system that boosts the stability of OW emulsions and helps to reduce the amount of the primary emulsifier. It is also a valuable trouble-shooter, it helps formulators to recoup OW emulsions that are not perfectly stable after emulsification as it can be added “on the fly” at the cold process. Formulators can prepare a wide range of products with oil concentrations as low as 2% and as high as approximately 50% without any unpleasant oily feel. COSMOS approved.
  • It is both an emulsifying agent and a co-emulsifying system.
  • Oily liquid ready to use without being dissolved and heated, excellent stability at high and low temperatures and pH, good water resistance thanks to the formation of a superficial hydrophobic film.
  • Excellent sensorial characteristics: long-lasting emollient/moisturizing effect. It leaves no oily feel or greasy appearance.
  • Soluble in vegetable oils, fatty alcohols, fatty acids and their esters, dispersible in warm water and miscible in mineral oils.
  • It helps in reducing the amount of the primary emulsifier stabilizing emulsions with different viscosities and limiting the thixotropic effect.
  • Does not modify the HLB of the emulsifier and has no destabilizing effects on liquid crystal structures.

STABILGREEN K® is similar to the natural phospholipids found in the skin, so it is immediately available when the cream is applied to the epidermis.
The development of natural analogues also improved the emulsification power and the resistance to oxidation and enzymatic degradation.

Stabilizer ideal for OW emulsions containing high amounts of zinc oxide and titanium dioxide (sun care and anti-redness emulsions )

% OF USE: 0.5 – 1.0% as co-emulsifier or “trouble shooter”

% OF USE: 2.0 – 3.0% as sole emulsifier
