TEGO® Care 165 (Glyceryl Stearate (and) PEG-100 Stearate) from Evonik is a non-ionic emulsifier suitable for the
formulation of O/W creams and lotions. It has excellent compatibility with
active ingredients, can tolerate significant amounts of electrolytes and is
applicable in a wide pH range and in emulsions with high heat and freeze
stability. TEGO® Care 165 is suitable for the formulation of O/W creams and
lotions in products for facial care and hand and body care.
Benefits at a glance
▪Emulsifier for O/W creams and lotions with pleasant
▪Excellent compatibility with active ingredients.
▪Tolerate significant amounts of electrolytes.
▪Applicable in a wide pH range.
▪Emulsion with high heat and freeze stability
▪TEGO® Care 165 is a non-ionic emulsifier suitable
for the formulation of O/W creams and lotions.
▪It is based on vegetable raw materials.
▪A typical usage concentration of 2 – 10% TEGO® Care 165 is recommended. In general,no co-emulsifiers are needed to obtain stable emulsions.
▪Emulsions based on TEGO® Care 165 show good
application and stability properties, if they contain 15 – 30% of oil phase
▪TEGO® Care 165 should be used in combination with
consistency-providing substances for the formation of viscosity-enhancing
liquid crystalline structures in the
external water phase. TEGO® Alkanol 16 (Cetyl Alcohol), Stearyl
Alcohol or TEGO® Alkanol 1618 (Cetearyl Alcohol) have proved to be the most effective
stabilizing agents. These consistency enhancers form together with the
emulsifier lamellar networks in the water phase. The viscosity of the external
phase is increased and the emulsion stability is improved.
▪Depending on the formulation 0.1 - 0.3% Carbomer
are necessary to improve the freeze stability of the emulsions.
▪TEGO® Care 165 forms stable emulsions with all
common oils and fats used for cosmetic skin care products, including polar
▪Formulations based on TEGO® Care 165 tolerate the
addition of significant amounts of electrolytes.
▪Emulsions can be pH adjusted to between 4.5 and
We recommend melting TEGO® Care 165 together with
the oil phase. Mixing temperature of oil and water phase is between
70 and 75 °C. The oil phase is added to the water phase with stirring. The coarsely dispersed pre-emulsion
is then homogenized. (The homogenizer must be placed in the water phase.)
If necessary because of production considerations the
water phase can be added to the oil phase without stirring (to avoid the
building of the water-in-oil form) and then homogenized. (The homogenizer must be placed in the water phase.) After homogenization the Carbomer dispersion in oil
at 20% in mineral oil or TEGOSOFT® OS (Ethylhexyl Stearate) is added and the emulsion is homogenized again
for a short time. Avoid the use of triglyceride based
esters for dispersion of the Carbomer.
During cooling, a constant horizontal and vertical movement
of the emulsion has to be ensured. The viscosity of the liquid emulsion
increases consistency, as the hydrated consistency promoters solidify. Perfume,
temperature-sensitive substances or electrolyte containing ingredients should
be added at 35 - 45 °C. Neutralization of the emulsion is completed at approx.
