Emulsifiers for Skin Care Applications

Vegetable based Emulsifiers
• TEGINACID ® C (Ceteareth-25)
• TEGINACID ® H (Glyceryl Stearate, Ceteth-20)
• TEGO ® Care 165 (Glyceryl Stearate (and) PEG-100 Stearate)
One outstanding property of the TEGINACID ® products is their stability in acid or weakly alkaline formulations (pH values
between 4.0 and 8.5). While TEGINACID ® C is mainly suitable for the formulation of cosmetic and pharmaceutical creams, the
main applications of TEGINACID ® H are O/W lotions.
TEGO ® Care 165 is especially of interest for the processing of low cost mass market O/W emulsions. Creams and lotions containing
TEGO ® Care 165 show improved compatibility with higher concentrations of electrolytes.
Cationic Emulsifiers
• VARISOFT ® TA 100 (Distearyldimonium Chloride)
• VARISOFT ® PATC (Palmitamidopropyltrimonium Chloride)
• TEGO ® Care CE 40 (Cetearyl alcohol (and) Palmitamidopropyltrimoniumchloride)
Creams and lotions formulated with the cationic vegetable based emulsifiers of the VARISOFT ® family provide a specific non-oily
skin feel which might be favorable in formulations with higher lipid loadings. The specific properties of these formulations are due
to the cationic character of the emulsifier molecule. Because of this cationic character, stabilisation of the formulations with Carbomer
thickeners is not favourable. However, these emulsifiers are well compatible with all type of classical consistency enhancers.
Fields of Application
Body and Facial Care
Emulsifiers for Facial Care applications should ideally be natural and mild products that provide some additional benefits to facial
skin. These aspects are met when using the emulsifier TEGO ® Care 450. In a publication of Henkel “On the Choice of O/W
Emulsifiers for Use in Skin Care Products for Sensitive Skin” TEGO ® Care 450 was in-vivo tested as a very mild emulsifier.
Moisturizing properties as measured by corneometer have also been determined [1]. TEGO ® Care 450 can be seen as an excellent
emulsifier for Facial Care applications. Furthermore TEGO ® Care CG 90 and TEGO ® Care PS are also good emulsifiers with
moisturizing properties for Facial Care lotions and creams.
Consumers expect Hand Care products to be easily spread, quickly absorbed and to possess a lasting caring effect. In addition, a
hand cream should be difficult to wash off, i.e. it should not re-emulsify immediate on contact with water.
