Isooctanol phosphate ester is an anionic surfactant with strong surface activity. It shows excellent emulsifying, wetting, and dispersing properties, especially in high-temperature and alkaline environments.
Widely used in metal processing, textile auxiliaries, and industrial cleaning, it enhances lubrication and corrosion resistance. With good compatibility with other additives, it improves product stability and processing efficiency.
Product Advantage
5. Good Compatibility: Mixes well with 90% of anionic and non-ionic auxiliaries (tested in formulations), enabling flexible use in textile pre-treatment and industrial cleaning.

Product Uses
1. Metal Processing: Enhances lubrication in cutting and grinding, reducing tool wear by 25% (test data). Its corrosion inhibition prevents rust on workpieces during processing and storage, suitable for steel and aluminum handling.
2. Industrial Cleaning: Efficiently removes heavy grease in alkaline baths (pH 10-13), with 92% oil removal rate. Ideal for cleaning machinery parts and industrial equipment in high-alkali environments.
3. Textile Auxiliaries: Improves wetting of fabrics in pre-treatment, boosting dye absorption by 15%. Compatible with alkaline scouring agents, enhancing processing efficiency for cotton and polyester.
4. Emulsion Stabilization: Stabilizes oil-in-water emulsions in metalworking fluids, maintaining uniformity for 30+ days. Reduces emulsion breakdown in high-temperature machining processes.
Product Operate Guide
For Isooctanol phosphate ester, add 0.5%-3% to formulations (adjust by use). Stir at 40-60℃ for 5-10 mins to dissolve. Mix with other additives slowly. Avoid strong acids. Seal and store in cool place. Stir well if layered before reuse.
FAQ
1. What if I use more than 3% of Isooctanol phosphate ester?
Excess may cause foam or affect formulation stability. Reduce to 0.5%-3% and test; overuse rarely improves performance but increases cost.
2. Can it be stored at low temperatures?
Avoid freezing (below 0℃) as it may layer. Thaw at 20-30℃ and stir well—performance remains unaffected if handled properly.
3. Is it compatible with cationic surfactants?
Limited compatibility. Mixing may cause precipitation. Test 1:10 ratio first; better to pair with anionic/non-ionic types.
4. How to handle skin contact?
Rinse with plenty of water for 15 mins. If irritation occurs, seek medical help. Wear gloves during handling as a precaution.
