Q1: What is the CAS Registry Number for Cleaner RZQ-3070?
A: Cleaner RZQ-3070 is a proprietary multi-component formulation and does not have a single CAS number; its constituent substances are individually REACH-registered, and full compositional disclosure is available under NDA upon request.
Q2: What is the recommended working concentration and temperature range?
A: Typical dilution is 3–8% v/v in deionized or softened water; effective cleaning occurs between 40°C and 65°C, with optimal soil removal at 55°C ± 5°C for immersion and 50°C ± 3°C for spray applications.
Q3: How does RZQ-3070 compare to solvent-based cleaners like nPB or TCE in terms of residue and safety?
A: Unlike nPB or TCE, RZQ-3070 leaves no volatile organic residue, eliminates inhalation toxicity risks, requires no explosion-proof equipment, and avoids ozone-depleting substance (ODS) and carcinogen classifications—while delivering comparable particulate and oil removal on engineered metals.
Q4: Has RZQ-3070 been evaluated for extractables and leachables (E&L) in contact with pharmaceutical-grade stainless steel?
A: Yes—per USP <87> and <88> cytotoxicity testing, RZQ-3070 shows no adverse biological reactivity; E&L studies (ICH Q5C) confirm undetectable levels (<0.1 ppm) of non-volatile residues after final rinse with WFI at 60°C.
