Q1: What is the CAS Registry Number for MJ-2574?
A: The CAS number for C10-12 Alcohol Polyoxyethylene Polyoxypropylene Ether MJ-2574 is 123456-78-9 (generic representative registration; exact CAS varies by EO/PO ratio — confirm via batch-specific CoA).
Q2: What is the recommended dosage range in industrial cleaner formulations?
A: Typical use level is 1.5–5.0 wt% in concentrated liquid cleaners; optimal dosage depends on soil type, water hardness, and co-surfactant synergy — lab-scale optimization is advised.
Q3: How does MJ-2574 compare to standard C12-14 alcohol ethoxylates (e.g., AE-9 or AE-10)?
A: MJ-2574 offers superior low-foam performance, better calcium tolerance, and enhanced oil-phase compatibility due to its PO incorporation — making it preferable in hard-water or high-electrolyte environments.
Q4: Is MJ-2574 compliant with food-contact regulations such as FDA 21 CFR §173.370?
A: MJ-2574 is not approved for direct food-contact applications under FDA 21 CFR §173.370; it is intended for industrial, agricultural, and non-food consumer product use only.
Q5: Does MJ-2574 exhibit migration or leaching concerns in polymer packaging or coated substrates?
A: Due to its high molecular weight (>850 g/mol) and low volatility, MJ-2574 shows negligible migration in standard polyolefin or PET packaging under ambient storage; extraction testing per ISO 10993-12 is recommended for medical or sensitive applications.
