Why It Matters
Carrier and solubilizer systems for vitamins, retinoids, peptides, and botanical actives — protecting potency through shelf life
Solution Approach
Carrier and solubilizer systems for vitamins, retinoids, peptides, and botanical actives — protecting potency through shelf life 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 Treatment Workflow
1
System Assessment
Characterize operating conditions—fluid composition, temperature, pressure, flow rates—and benchmark current treatment performance.
2
Chemistry Selection
Match base chemicals to your operating envelope. Factor in compatibility with existing programs, regulatory constraints, and downstream impacts.
3
Dosage & Delivery
Determine optimal treat rates through jar testing or field trials. Configure packaging (drums, totes, ISO tanks) to match consumption and storage logistics.
4
Monitoring & Adjustment
Track KPIs—coupon rates, residuals, separator performance, water quality. Adjust chemistry and dosage as conditions change.
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
Full Details
Butylene Glycol
CAS 107-88-0
Glycols & Polyols
Humectant and co-solvent for actives
Mild glycol carrier commonly used to disperse botanical extracts and stabilize actives in the water phase
Physical Description: Very hygroscopic liquid; Pure form is colorless Appearance: Pure compound is colorless Odor: Practically odorless
Full Details
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
Full Details
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
Full Details
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
Full Details
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/
