TEGO® Care PSC 3 MB – A natural, cost-efficient O/W emulsifier with excellent performance – COSMOS APPROVED

TEGO® Care PSC 3 is a natural, non-ionic, PEG-free and cost efficient O/W emulsifier suitable for all types of cosmetic O/W creams and lotions. Good compatibility with active ingredients and electrolytes. Designed for stable emulsions from pH 3.5 – 8.5. Intended use :O/W emulsifier INCI (PCPC name) : Polyglyceryl-3 Dicitrate/Stearate Recommended usage concentration of TEGO® Care PSC 3 MB is approx. 3.0% in creams and 1.5 – 3.0% in lotions. TEGO® Care PSC 3 MB is a non-ionic, PEG-free emulsifier that is completely based on renewable raw materials. TEGO® Care PSC 3 MB is based on glycerol, stearic acid and citric acid. In a first step, a polycondensation reaction of glycerol to polyglycerol-3 is carried out. Polyglycerol-3 is subsequently esterified with stearic acid and a substoichiometric amount of citric acid. TEGO® Care PSC 3 MB provides excellent stabilization for all types of classical O/W creams and lotions. TEGO® Care PSC 3 MB is suitable for the formulation of O/W creams and lotions with all types of cosmetic oils at a pH of 3.5 to 8.5. Typical oil phase contents of emulsions based on TEGO® Care PSC 3 MB are 20 – 35% for creams and 10 – 25% for lotions. Typical combinations for O/W creams are 3.0% TEGO® Care PSC 3 MB with 2.5 – 4.0% consistency enhancers. Suitable combinations include TEGIN® M Pellets MB (Glyceryl Stearate) and Stearyl Alcohol in a ratio of 70:30 or 50:50. In most O/W lotions, 2 – 3% of TEGO® Care PSC 3 MB is already sufficient to obtain the desired viscosity and stability profile, without additional consistency enhancers. It is recommended to combine TEGO® Care PSC 3 MB with Xanthan Gum (0.2% for creams and 0.3 to 0.5% for lotions) in order to optimize the texture and stability of the emulsions. In order to avoid a negative impact on the lamellar structures formed by the emulsifier and consistency enhancers, it is recommended to add Xanthan Gum below 40 °C to the emulsions. TEGO® Care PSC 3 MB is particularly recommended for the formulation of face and body care products. As it is a natural based emulsifier, it also represents an interesting option for baby care products.
