Solution Approach
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
Concept & Claim Definition
Define the product type, sensory and claim targets, and the regulatory and label framework (INCI, regional cosmetic regulations, certifications).
2
Ingredient Selection
Match emollients, emulsifiers, surfactants, actives, preservatives, or rheology modifiers to the formula, skin-feel, and compatibility window.
3
Bench Formulation
Build and stabilize the emulsion or system at the bench, checking pH, viscosity, preservative efficacy, and aesthetics.
4
Stability & Compliance Validation
Run stability and compatibility testing, confirm preservative efficacy, and finalize the INCI, CoA, and documentation.
Recommended Chemistries (6)
