Approche de solution
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 Selection Workflow
1
Process & Requirement Definition
Map the unit operation and define the functional, purity, and regulatory requirements the chemical input must meet.
2
Chemistry & Grade Selection
Match the solvent, intermediate, acid or base, catalyst, or specialty additive to the process and downstream compatibility.
3
Trial & Specification
Validate performance at bench or pilot scale, and set the grade, treat rate, and packaging to match throughput and handling.
4
Quality & Supply Assurance
Lock the spec with a CoA and secure multi-origin sourcing for supply resilience and consistent lot quality.

Additifs de Spécialité
Antimousse / Contrôle de la mousse
1274 (N-PROPANOL) · Class Low-surface-tension alcohol for transient foam knockdown where silicone carryover into the product is unacceptable
Point de fusion:-126 °C Point d'ébullition:97 °C at 760 mmHg Densité:0.803 at 20 °C

IPA (Isopropyl Alcohol)
CAS 67-63-0
Solvants
General-purpose cleaning solvent
1219 (ISOPROPANOL) · Class Structural isomer of the already-listed N-Propanol (both C3H7OH); near-identical low surface tension (~21.7 mN/m) and water-miscibility give the same Marangoni-suppression / foam-lamellae destabilization mechanism and the same silicone-free, no-PDMS-residue transient-knockdown value. A genuine direct analog to the incumbent, not a role-only look-alike.
Point de fusion:-88 °C Point d'ébullition:82 °C at 760 mmHg Densité:0.785 at 20 °C

Ethanol
CAS 64-17-5
Water-miscible low-surface-tension (~22 mN/m) short-chain alcohol and a well-established aqueous/protein foam breaker via the same film-destabilization mechanism. Slightly less hydrophobic than the propanols but same class and same silicone-free niche; its higher volatility strengthens the no-residue story for contamination-sensitive process lines. Genuinely serves this exact use-case.
