Q1: What is the primary function of Lutensit AN50 in formulations?
A: Lutensit AN50 is an amphoteric surfactant designed to provide mild cleansing, foam stabilization, and viscosity enhancement—particularly in aqueous personal care systems such as shampoos, body washes, and facial cleansers.
Q2: Is Lutensit AN50 compatible with anionic and cationic ingredients?
A: Yes, due to its amphoteric nature, Lutensit AN50 exhibits broad compatibility across ionic classes—including anionics (e.g., SLS, SLES), nonionics, and select cationics—making it suitable for complex, multi-surfactant systems without significant precipitation or instability.
Q3: How does pH affect the performance and stability of Lutensit AN50?
A: Lutensit AN50 performs optimally in mildly acidic to neutral pH ranges (approximately pH 4.5–7.0), where its zwitterionic character supports effective surface activity and solubility. Performance may diminish under strongly alkaline conditions due to charge imbalance.
Q4: Can Lutensit AN50 be used in rinse-off versus leave-on applications?
A: It is primarily formulated for rinse-off products such as shampoos and body washes, where its mildness, foaming synergy, and biodegradability align with regulatory and consumer expectations. While not prohibited in leave-on systems, formulation compatibility and sensory performance should be verified case by case.
Q5: What are typical dosage recommendations for Lutensit AN50 in surfactant blends?
A: Dosage depends on formulation requirements, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—to optimize foam quality, mildness, and viscosity without compromising clarity or stability.
