Addition Order & Process
Manufacturing procedure: Disperse esterquat into agitated water (ambient, 30 minutes) . Add calcium chloride to reduce viscosity to 500–700 cP. Add aminosilicone microemulsion (prediluted 1:1 with water at 40 °C) slowly with moderate shear. Add cationic thickener (predispersed in 45 °C water) and color-protection polymer at 35 °C . Add laureth-7, mix 15 minutes. Incorporate perfume capsules at low shear (150 rpm). Add free fragrance, colorant, and preservative. Adjust pH to 2.8–3.2 .
Expected Parameters
Key parameters: Active matter 15.3% ± 0.5%; total fragrance 1.31%; viscosity 500–700 cP (Brookfield LVT, 25 °C); pH 2.8–3.2 . Aminosilicone at 2.0% reduces wrinkle formation by 25–30% versus esterquat-only (AATCC Test Method 128-2017, cotton twill, n=5) .
Formulation Notes
The premium formulation maximizes softening intensity, adds silicone for enhanced hand-feel and wrinkle reduction, incorporates color-protection polymers, and deploys a dual-fragrance system (free oil plus encapsulated) for complex, layered scent profiles.
