Why It Matters
Design uses phosphoric/citric acids and chelants to dissolve calcium carbonate, iron and mineral deposits from hard surfaces
Solution Approach
Design uses phosphoric/citric acids and chelants to dissolve calcium carbonate, iron and mineral deposits from hard surfaces 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.
