Q1: What is the CAS Number for C9-11 Alcohol Ethoxylate MJ-R90?
A: The CAS Number is 68439-49-6 (generic for C9–C11 alcohol ethoxylates with ~9 EO units); exact batch-specific CAS verification available upon request with COA.
Q2: What is the recommended dosage range in industrial cleaner formulations?
A: Typical use level is 2–8 wt% active in ready-to-use liquid cleaners; optimal performance observed at 4–6 wt% when combined with 1–3 wt% anionic co-surfactant.
Q3: How does MJ-R90 compare to C12-15 alcohol ethoxylates (e.g., AEOD-9) in terms of solubility and cleaning power?
A: MJ-R90 offers higher water solubility and faster wetting kinetics than C12–15 analogues, with superior low-temperature performance; cleaning power on polar soils is comparable, while its lower HLB (~13.2) enhances oil removal in neutral-pH systems.
Q4: Is MJ-R90 compliant with food-contact regulations (e.g., FDA 21 CFR §173.370)?
A: MJ-R90 is not pre-approved under FDA 21 CFR §173.370; however, it may be used in indirect food-contact applications (e.g., equipment cleaners) subject to full validation and residual limits per FDA’s Threshold of Regulation (TOR) guidance.
Q5: Does MJ-R90 exhibit migration or extraction risk in polymer packaging (e.g., HDPE, PET)?
A: Migration potential is negligible under ambient storage conditions; no significant leaching observed in standardized PET/HDPE extraction studies (EN 13130-1, 10 days @ 40 °C, 10% ethanol simulant).
