Powder Detergent – Whitening Performance Benchmark

This research benchmarks whitening performance of a powder detergent formula on cotton and blended fabrics. Primary objective is high stain removal with minimal fiber harshness.

Method: Standardized stained swatches (tea/coffee) were washed at 50°C with fixed water hardness. Whitening was evaluated using before/after visual comparison and standardized scoring.

Conclusion: Excellent whitening and good rinse behavior. Consider minor fragrance adjustment for premium feel.
