Formulation Notes
The premium tier maximizes cleaning performance, fabric care, and sensorial attributes. FC-6.1-P incorporates AOS for hard-water tolerance, APG for mildness and sustainable positioning, GLDA for chelation, a four-enzyme blend for comprehensive stain coverage, optical brightener at full dosage, and perfume microcapsules for extended fragrance delivery. Active matter at 20–25% positions this formulation in the super-concentrated segment.
Formulation Card FC-6.1-P: Premium Liquid Laundry Detergent
AOS at 10% (3.8% active) provides superior lime soap dispersion power (LSDP 9.5 g/g vs. 4.5 g/g for LAS) and extends hard-water tolerance to >500 mg/L CaCO₃.APG at 6% (3% active) contributes mildness for sensitive-skin positioning and ISO 16128 natural origin index compliance.The four-enzyme system (protease + amylase + lipase + cellulase) covers protein, starch, triglyceride, and cellulose microfibril soils respectively — the most comprehensive enzyme package presented in this chapter. Perfume microcapsules at 2% (0.6% active fragrance oil) deliver friction-triggered release for up to 12 weeks on stored fabric, complementing the 0.5% neat fragrance that provides immediate in-wash and in-bottle freshness.Table 6.1 — Standard Liquid Laundry Detergent Tier Comparison (FC-6.1-E / M / P)
The data in Table 6.1 illustrate three distinct performance-cost trade-offs. At the economical tier, the cost per kilogram is minimized but the dosage per wash is maximized (75–100 g), resulting in only marginal savings per wash cycle versus the medium tier. The medium tier at 165% of the economical cost delivers a 50% reduction in dosage (50–75 g) and a meaningful cleaning improvement through enzyme inclusion and CAPB viscosity synergy, making it the dominant market position. The premium tier at 280% of the economical cost achieves the lowest dosage (35–50 g) and the broadest performance envelope: hard-water tolerance via AOS, mildness via APG, comprehensive enzymatic stain removal, and extended fragrance via microencapsulation. For formulators, the decision between tiers should be driven by target market water hardness, consumer price sensitivity, and retail positioning rather than by raw material cost alone.
