Why It Matters
Liquid-cleaner and detergent formulators search for hydrotropes to solubilize surfactants and keep concentrates clear and stable. Hydrotropes such as SXS, naphthalene sulfonate, SCS and toluene sulfonate keep concentrates clear and stable.
Solution Approach
Liquid-cleaner and detergent formulators search for hydrotropes to solubilize surfactants and keep concentrates clear and stable. Hydrotropes such as SXS, naphthalene sulfonate, SCS and toluene sulfonate keep concentrates clear and stable. 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.
