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)
Propylene Glycol, USP/FCC Food Grade
CAS 57-55-6
Glycols & Polyols
Humectant, solvent, and preservative booster
Polar co-solvent that dissolves water-marginal actives and depresses water activity, aiding delivery and formula robustness
Melting Point: -60 °C Boiling Point: 188 °C at 760 mmHg Density: 1.04 at 20 °C

Polysorbate 80 (Tween 80), FCC Food Grade
CAS 9005-65-6
Surfactants
Nonionic emulsifier for oils and lipophilic actives
Nonionic surfactant that micellizes oil-soluble actives (e.g., tocopherol, fragrance) into clear aqueous systems

D-a Tocopheryl Acetate
CAS 58-95-7
Specialty Additives
Antioxidant vitamin E derivative
The acetate ester caps the phenolic OH, so it is not antioxidant-active in the pack until cleaved by skin esterases; it is a hydrolytically stable vitamin-E carrier — the real in-formula antioxidant/chelant load here is carried by BHT and Disodium EDTA
Melting Point: 28 °C Boiling Point: 184 °C at 0.01 mmHg Density: 0.9507 at 26 °C

BHT (Butylated Hydroxytoluene), Food Grade
CAS 128-37-0
Specialty Additives
Lipid antioxidant for oil phase protection
Chain-breaking radical scavenger in the oil phase that suppresses peroxidation of retinoids and unsaturated oils, preserving potency
Melting Point: 69–71 °C Boiling Point: 265 °C at 760 mmHg Density: 1.048 at 20 °C

Disodium EDTA (Food Grade)
CAS 139-33-3
Specialty Additives
Metal chelant for formula stability and preservative efficacy
Removes trace transition metals that catalyze oxidative degradation of vitamins and retinoids over shelf life
Physical Description: White odorless solid; White odorless crystals Appearance: White crystalline powder Melting Point: MP: 242 °C /EDTA disodium dihydrate/
