TMPTO, PEG-400 dioleat, etoksillangan kastor moyi (ECO), sulfatlangan kastor moyi (SCO) va natriy poliakrilatdan iborat APEO-free tekstil bo‘yash moyining 20 ta cheklangan D-optimal formulasi eksperimental tekshirildi. Birlamchi javoblar sifatida 40 °C dagi kinematik qovushqoqlik (ν40), sirt tarangligi (γ), 7 kunlik emulsiya barqarorligi (ES), tola-tola (μff) va tola-metall (μfm) ishqalanish koeffitsientlari olindi. 20 tajribaga moslashtirilgan to‘liq ikkinchi tartibli Scheffé modellari barcha javoblar uchun statistik ahamiyatli bo‘ldi (R²=0.9863–0.9986; p≤0.00104). B-20 (38.2/28.1/17.1/10.5/6.1 mass.%) uchun ν40=21.5 mm²/s, γ=33.2 mN/m, ES=93.5%, μff=0.21 va μfm=0.17, umumiy desirability D=0.854 bo‘ldi. Kolloid validatsiyada D50=185 nm, PDI=0.24 va ζ=-32.0 mV qayd etilib, 500 mg/L CaCO3 qattiqligidagi suvda to‘liq barqarorlik kuzatildi. Oqartirilgan va merserizatsiyalangan 100% paxta matosini (145 g/m²) Reactive Blue 19 bilan n=3 bo‘yashda B-20 K/S=15.65±0.15, bo‘yoq yutilishi=93.50±0.26% va CV(K/S)=0.88±0.06% natijalarni berdi; blankda mos ravishda 11.25±0.18, 68.30±0.56% va 3.10±0.11%, tijorat analogida 14.82±0.13, 88.17±0.40% va 1.45±0.07% olindi. Bir omilli ANOVA va Tukey HSD asosiy koloristik ko‘rsatkichlar bo‘yicha guruhlar orasida statistik ahamiyatli farqlarni ko‘rsatdi (p<0.01). Natijalar B-20 ni kolloid barqarorlik, boshqariladigan ishqalanish va bo‘yash sifati bo‘yicha muvozanatlangan formula sifatida asoslaydi.
