Preservatives & Material Protection

Preservatives and sanitizer actives are two distinct ingredient classes: in-cannpreservatives that protect a cleaning product from microbial spoilage during storage, andnantimicrobial actives formulated into sanitizer and disinfectant products. RawSourcensupplies both as raw-material actives. Finished products that make antimicrobial or public-healthnclaims are regulated and must be registered with the U.S. EPA under FIFRA; confirm registration andnjurisdiction before making any claim.

Isothiazolinones are the common in-can preservatives. Methylisothiazolinone (MIT) and thenchloromethylisothiazolinone/methylisothiazolinone (CMIT/MIT) blend protect liquid cleaners at lownaddition levels. They are recognized skin sensitizers and are subject to use-level limits in somenproduct categories and jurisdictions, so set the addition level against the applicable regionalnrules. Confirm regulatory status for your application and jurisdiction.

For sanitizer and disinfectant formulations the choice is usually between oxidizing actives andnquats. Sodium hypochlorite and hydrogen peroxide are oxidizers; benzalkonium chloride (BKC) is ancationic quaternary active. The practical trade-off is handling, not a claim: oxidizers raisenmaterial-compatibility and storage-stability questions, while quats are more stable in formula butnare cationic and can clash with anionic surfactants. RawSource supplies these as actives, not asnregistered end-use products.
