Functional Role of Raw Materials & Recommended Suppliers
Document covers the functional role of each ingredient used in the Caustic-Free Low Foam Spray Liquid Degreaser and practical supplier/trade-family options suitable for industrial spray degreasing systems.
Raw Materials – Role + Supplier Recommendations
Low Foam • Spray Compatible
| S.No | Raw Material (Generic) | Primary Functional Role | Key Benefits / Notes | Trade-Family (Examples) | Recommended Suppliers (Examples) |
|---|---|---|---|---|---|
| 1 | Demineralized Water | Carrier / Diluent | Controls viscosity & concentration; low conductivity reduces spotting; avoids nozzle scaling. | DM / RO + MB polished water | Ion Exchange (India), Thermax, local industrial DM water plants |
| 2 | Nonionic Surfactant (EO/PO, low foam) | Primary degreasing surfactant | Wetting + emulsification of oils; low dynamic foam in spray; improves rinse and soil removal. | EO/PO block copolymer or low-foam alcohol ethoxylate (LF grade) | BASF, Dow, Clariant, Galaxy Surfactants (India) / authorized distributors |
| 3 | Amine Oxide (low foam type) | Auxiliary surfactant + foam regulator | Synergy with nonionic for oily soils; improves detergency and robustness; controlled foam profile. | Lauryl/Myristyl amine oxide (industrial grade) | Lonza, Stepan, Nouryon (ex-Akzo specialty chemicals), Galaxy Surfactants / Indian distributors |
| 4 | Sodium Gluconate | Chelator / water hardness control | Binds Ca/Mg/Fe; improves surfactant efficiency; reduces scaling & sludge; stabilizes bath life. | Sodium gluconate (98% powder or solution) | Jungbunzlauer, Roquette, Indian industrial chemical suppliers / importers |
| 5 | Hydrotrope (Sulfobetaine / Sulfonate) | Solubilizer + phase stability | Keeps blend single-phase; prevents haze/separation; improves wetting & rinse; supports oil dispersion. | Sodium xylene sulfonate (SXS) / sulfonate hydrotropes; sulfobetaine options | Stepan, Galaxy Surfactants, BASF (via distributors) / Indian specialty chemical suppliers |
| 6 | Polymer Dispersant (polyacrylate type) | Anti-redeposition / dispersing agent | Keeps removed oils/soils suspended; reduces redeposit; lowers sludge settling; extends bath life. | Polyacrylate / acrylic copolymer dispersant | BASF (Sokalan/Dispex families), Dow (Acumer family), Indian polymer additive suppliers |
| 7 | Preservative / Biocide (optional) | Microbial control | Prevents bacterial growth, odor, viscosity drift; improves shelf life in warm climate storage. | BIT / CMIT-MIT (as per regulations & compatibility) | Thor, Dow, Lonza / authorized distributors; local biocide suppliers |
Functional Architecture (Quick Map)
How it works
- Oil removal: Nonionic EO/PO + Amine Oxide
- Hardness control: Sodium Gluconate
- Single-phase stability: Hydrotrope
- Anti-redeposition: Polymer Dispersant
- Shelf stability: Preservative/Biocide
- Carrier medium: DM Water
Tip: Always evaluate foam in a recirculating spray test (dynamic foam), not only in beaker shake tests.
Purchase Notes (Practical)
Procurement
- Ask for low dynamic foam data (Ross-Miles / foam profile at use dilution).
- Prefer industrial grade surfactants for spray degreasing (temperature & soil tolerance).
- Confirm cloud point / clarity of nonionic at intended dilution and temperature.
- Verify dispersant compatibility (no haze) and stability at 5–45°C.
- Biocide selection should follow local compliance and compatibility with surfactants.
