RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Processing Workflow
1
Substrate & Process Assessment
Identify the fiber and process stage (pretreatment, dyeing, finishing) and the performance, hand, and compliance targets.
2
Auxiliary Selection
Match surfactants, wetting and dispersing agents, softeners, fixatives, or pH and sequestering agents to the substrate and bath chemistry.
3
Lab Dip & Dosing
Confirm dose and sequence on a lab dip or pad trial, checking levelness, fastness, hand, and bath stability.
4
Production Validation
Verify reproducibility, fastness, and effluent compliance at scale, and set the recipe and packaging for production.

2-Hydroxyphosphonocarboxylic Acid (HPAA)
CAS 23783-26-8
Phosphorsäureester & Derivate
Chelatisierung / Sequestrierung
Oxidant-stable phosphonocarboxylate chelant purpose-built for this exact problem: it sequesters the catalytic Fe/Mn/Cu that drive uncontrolled H2O2 decomposition, and its resistance to oxidation lets it survive in the peroxide bath itself. Functions as a genuine peroxide bleach stabilizer at the alkaline pH (~10.5-11) of textile bleaching, delivering even whiteness while preventing radical-driven
Physical Description: Brown liquid. Slight acrid odor
