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 Formulation Workflow
1
Application & Soil Assessment
Define the cleaning task, surfaces, soils, and water hardness, plus the safety and regulatory profile for the use environment.
2
Surfactant & Builder Selection
Match surfactants, builders, solvents, chelants, acids or alkalis, and preservatives to the soil, surface compatibility, and label claims.
3
Formulation & Use-Dilution Trial
Optimize the actives ratio and use dilution, checking foam, clarity, stability, and performance at the in-use concentration.
4
Performance & Stability Validation
Confirm cleaning efficacy, storage and freeze-thaw stability, and packaging compatibility before scale-up.
