Raw Materials
Active matter: 14.6% ± 0.6%. AvO: 1.84% ± 0.15%. TAED:percarbonate = 1:3 (optimum 1:2 to 1:4).No zeolite — soda ash + MGDA avoids percarbonate-zeolite decomposition.Addition Order: Spray-dry base (LAS, AE-9EO, soda ash, sulfate, CMC, silicate); cool to < 30 °C. Post-add percarbonate + TAED (pre-blended), MGDA, brightener + perfume.
Safety Notes: Percarbonate-organic mixtures can exotherm — DSC screening before scale-up.Expected Problems & Solutions: Bleach odor: use marine/floral fragrances; avoid citrus.
QC Tests: AvO (1.70–1.98%); percarbonate stability (≥ 80% at 8 weeks/32 °C, 80% RH); TAED (HPLC, 4.5–5.5%).
Cost Notes: ~USD 1.15–1.40/kg.
