Why It Matters
Emulsifier-system / HLB optimization for stable W/O and O/W creams that pass extended stability protocols
Solution Approach
Emulsifier-system / HLB optimization for stable W/O and O/W creams that pass extended stability protocols 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)
Glyceryl stearate
CAS 31566-31-1
Esters
Self-emulsifying base for creams and lotions
Low-HLB self-emulsifier that builds a lamellar liquid-crystal gel network at the O/W interface, immobilizing droplets so they can't coalesce
Full Details
Ceteareth-40 Solid
CAS 68439-49-6
Specialty Additives
Nonionic emulsifier for O/W emulsions
High-HLB (~17) nonionic that pairs with a low-HLB co-emulsifier to hit the required HLB of the oil phase, lowering interfacial tension for a fine, stable O/W droplet population
Full Details
Acrylates/C10-30 Alkyl Acrylate Crosspolymer
CAS 176429-87-1
Polymers & Resins
Pemulen-type emulsion stabilizer and thickener
Pemulen-type crosspolymer that builds yield value in the water phase, suspending oil droplets in a weak gel so creaming and phase separation are arrested
Full Details
Ceto-Stearyl Alcohol
CAS 67762-27-0
Specialty Additives
Waxy emollient and viscosity builder
Fatty-alcohol consistency factor that swells the lamellar network with the primary emulsifier, raising viscosity and locking in the emulsion
Full Details
Polysorbate 80 (Tween 80), FCC Food Grade
CAS 9005-65-6
Surfactants
Nonionic emulsifier for oils and lipophilic actives
Nonionic emulsifier (HLB ~15) for lipophilic oils and oil-soluble actives, used to fine-tune the blend HLB toward the oil-phase requirement
Full Details
Disodium EDTA (Food Grade)
CAS 139-33-3
Specialty Additives
Metal chelant for formula stability and preservative efficacy
Sequesters trace Ca/Mg/Fe that catalyze rancidity and destabilize anionic emulsifiers, protecting the emulsion through accelerated-stability testing
Physical Description: White odorless solid; White odorless crystals Appearance: White crystalline powder Melting Point: MP: 242 °C /EDTA disodium dihydrate/
