Q1: What is the primary function of Emulan TO4070 in cosmetic and personal care formulations?
A: Emulan TO4070 is a non-ionic O/W emulsifier designed to stabilize oil-in-water emulsions, particularly in low- to medium-oil-content systems such as light lotions, gels, and aqueous serums. It supports elegant skin feel, rapid absorption, and good compatibility with common actives and preservatives.
Q2: Is Emulan TO4070 suitable for use in rinse-off versus leave-on products?
A: Yes — Emulan TO4070 performs well in both rinse-off applications (e.g., cleansing milks or micellar waters) and leave-on products (e.g., moisturizing lotions), thanks to its mildness profile and ability to deliver stable, low-viscosity emulsions that rinse cleanly or absorb readily without residue.
Q3: How should Emulan TO4070 be incorporated into a formulation?
A: It is typically added to the aqueous phase at ambient to warm temperatures (up to ~45 °C) and homogenized with the oil phase under moderate shear. Pre-dilution in water or glycerin may aid dispersion. Processing temperature and shear intensity should be optimized based on the full formulation matrix.
Q4: Does Emulan TO4070 require co-emulsifiers or stabilizers in most systems?
A: In many standard emulsions, Emulan TO4070 can function effectively as a primary emulsifier without co-emulsifiers. However, for enhanced stability in challenging systems — such as those with high electrolyte content, volatile silicones, or polar oils — pairing with a secondary stabilizer (e.g., fatty alcohol or polymer) may be beneficial.
Q5: What are the key handling and storage recommendations for Emulan TO4070?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, protected from freezing and direct sunlight. Avoid prolonged exposure to elevated temperatures (>40 °C) prior to use. Ensure good hygiene during handling to prevent microbial contamination, especially in diluted form.
