ELFACOS® ST 37 emulsion stabilizers is a polyalkylene glycol supplied in a liquid form which has excellent stabilizing effects on emulsions. Due to its high capacity to absorb water and oil, a relatively low percentage is needed in personal care formulations. The stabilizing effect is not attributed to an increase of viscosity. Contrary, it reduces the viscosity of formulations to an extent that opens the possibility of manufacturing low viscosity, stable W/O emulsions. Non-ionic copolymer, ELFACOS® ST 37 emulsion stabilizers is hydrolytically stable and effective over wide pH ranges. It’s also tolerant to high concentrations of electrolyte.

ELFACOS®ST 37乳液稳定剂是以液体形式供应的聚亚烷基二醇，对乳液具有优异的稳定效果。由于其高吸收水和油的能力，在个人护理配方中需要相对较低的百分比。稳定效果不归因于粘度的增加。相反，它将配方的粘度降低到可以制造低粘度，稳定的W / O乳液的程度。非离子型共聚物，ELFACOS®ST 37乳液稳定剂在广泛的pH范围内具有水解稳定性和有效性。它也容许高浓度的电解质。
