Fuel Additive Components

03050 is a polymer mixture (typically ethylene-vinyl acetate or polyacrylate-based) that adsorbs onto the surface of growing wax crystals in diesel as the fuel cools. By altering crystal morphology — reducing crystal size and changing their shape — it prevents the interlocking network that causes the fuel to gel. This lowers both the pour point (temperature at which fuel loses flow) and the CFPP (Cold Filter Plugging Point, the more operationally relevant test). It does not eliminate wax formation but keeps the wax dispersed as fine crystals that pass through fuel filters.

AS700 is a hindered phenolic antioxidant that acts as a chain-breaking primary antioxidant. It donates hydrogen atoms to peroxy radicals (ROO•) formed during fuel autoxidation, interrupting the radical chain reaction before it propagates. This prevents the accumulation of hydroperoxides, which are the precursors to gum, varnish, and acidic degradation products. AS700 is liquid-form for easy handling and blends readily into both diesel and gasoline without heating.

Yes. 03050 (a wax crystal modifier) and AS700 (a radical-chain inhibitor) act by entirely different mechanisms and do not interfere with each other. They are routinely combined in the same treat package for winter diesel blends that need both cold-flow performance and storage stability. CheMost can advise on combined treat rates based on your base fuel properties and required specification targets.

Treat rates vary significantly by base fuel and target performance: 03050 PPD typically 200–1,000 ppm (0.02–0.1%) depending on the wax content and target CFPP improvement required; AS700 antioxidant typically 50–200 ppm for most diesel and gasoline storage applications. Both require optimization against your specific base fuel — treat rate testing on the actual fuel is strongly recommended before commercial blending. CheMost can support treat-rate optimization with technical guidance.

CheMost’s manufactured fuel range is focused on cold-flow (03050 PPD) and oxidative stability (AS700 antioxidant). A complete fuel additive package can also include cetane improver (2-ethylhexyl nitrate), lubricity additive (to restore the lubricity stripped from ULSD) and detergent / deposit-control chemistry — for those we advise on selection and can supply through qualified sourcing where it fits, and we state clearly which items are CheMost-manufactured versus sourced. Tell us the full package you need and we will scope what we make and what we source. The chemistry of each is covered on the Fuel & Refinery Additives hub.

Minimum order is typically 200 kg (one drum) for liquid components, with IBC (1,000 kg) available for bulk. Standard grades ship within 7–14 business days of order confirmation; cold-flow improvers may need 14–21 days, and pre-winter seasonal demand (October–November) can extend CFI lead times, so order early. Free 1–5 kg evaluation samples are available for qualified blenders. Contact us with the product, quantity and destination port for a specific lead-time and pricing confirmation.

Every shipment carries a TDS, a GHS SDS and a lot-specific COA, plus a Certificate of Origin for customs. HS-code classification and REACH substance-identity information are available on request, and for grades classified as dangerous goods we prepare IMDG (sea) or IATA (air) transport documentation. We do not issue ISO 9001 certificates or CICS registration documents.
