Q1: What type of thickening mechanism does NJCARE 305 employ?
A: NJCARE 305 is a non-ionic polymeric thickener that functions primarily through chain entanglement and hydration in aqueous systems, delivering stable viscosity enhancement without significant sensitivity to pH or electrolytes.
Q2: Is NJCARE 305 compatible with common preservatives and surfactants used in personal care formulations?
A: Yes, NJCARE 305 demonstrates broad compatibility with anionic, non-ionic, and amphoteric surfactants, as well as widely used cosmetic preservatives—including parabens, phenoxyethanol, and isothiazolinones—under typical formulation conditions.
Q3: How should NJCARE 305 be incorporated into a formulation to ensure optimal dispersion and performance?
A: For best results, pre-disperse NJCARE 305 in water or glycerin under moderate shear before adding to the main batch; avoid direct addition to highly ionic or low-pH phases without prior hydration. Gentle heating (up to 40–50 °C) may accelerate dissolution but is not required.
Q4: Does NJCARE 305 offer any rheological benefits beyond viscosity increase?
A: Yes—it imparts mild pseudoplastic (shear-thinning) behavior, supporting improved application feel and suspension stability while maintaining good flow at rest, making it suitable for gels, lotions, and cleansing bases.
Q5: Can NJCARE 305 be used in rinse-off versus leave-on products?
A: NJCARE 305 is formulated for versatility across both rinse-off (e.g., shampoos, body washes) and leave-on applications (e.g., moisturizing gels, serums), with performance tailored by dosage and formulation matrix.
