In a cleanroom, alcohol is often the “every-shift” workhorse: fast evaporation, low residue, and practical coverage for benches, carts, stainless panels, and gloved hands when used correctly. Sanihol ST is built for sterile areas where you want the convenience of a trigger spray but still need lot documentation, terminal sterilization, and tight endotoxin control.

SOSCleanroom has been a distributor of Decon for over 10 years supporting cleanrooms across the United States. That matters most when your QA team needs the same formulation, same documentation set, and predictable availability for ongoing programs—not a “close enough” substitute.

• Routine disinfection of hard, non-porous cleanroom surfaces when a sterile alcohol is required (e.g., staging tables, carts, pass-through interiors, stainless worktops).
• Sanitizing tasks where a 5-minute contact time is acceptable and controlled documentation is required.
• Glove and tool wipe-down workflows (when your facility allows alcohol use and you control flammability risk).
• Programs that require non-pyrogenic alcohol performance targets aligned to Water-for-Injection endotoxin limits (<0.25 EU/mL stated by the manufacturer).

• Sterile, terminally processed alcohol designed for controlled environments (0.2 µm filtration, double-bagging, gamma irradiation to SAL 10⁻⁶).
• Endotoxin control with a manufacturer-stated guarantee of <0.25 EU/mL (WFI criterion).
• Operationally realistic packaging — 16 oz. trigger spray for frequent use without decanting.
• Program documentation discipline — case-linked lot documentation describing QC, irradiation, sterility, and endotoxin limits.
• Published contact times for disinfection (10 minutes) and sanitation (5 minutes) on hard, non-porous surfaces.

Sanihol ST is a ready-to-use denatured ethanol solution filtered to 0.2 microns and packaged for sterile cleanroom use. The manufacturer lists the formulation (by volume) as: 63.4% ethyl alcohol, 3.2% methyl alcohol, 3.4% isopropyl alcohol, and 30% USP purified water.

From a contamination-control perspective, the “build” is as much about process as chemistry: filtration, cleanroom bottling, double-bagging, and gamma irradiation to protect sterility until use.

Alcohol performance in cleanrooms is less about “how strong” and more about how it is used: wet contact time, surface coverage, and how often you replace wipers/cloths during the wipe-down. Sanihol ST’s documented 0.2 µm filtration, sterile packaging controls, and endotoxin limit target are intended to reduce the variability that can show up when teams decant bulk alcohol or use non-sterile bottles in sterile areas.

• Wet contact time is the requirement. The label/published guidance calls for a minimum 10-minute wet time for disinfection on hard, non-porous surfaces and 5 minutes for sanitation.
• Residue profile. Alcohol typically flashes off without a rinse step for many applications, which is useful when you want fewer secondary wipes. Always confirm with your own residue/compatibility limits.
• Not a sporicide. Alcohols are widely used for routine disinfection/sanitation, but spore control typically requires a separate sporicidal program. Align the product to your site’s contamination control strategy and risk assessment.
• Material compatibility is surface-dependent. Alcohol can stress-crack some plastics (e.g., certain clear plastics) and can affect some painted/printed surfaces. Validate on representative coupons before broad rollout.

• Sterility controls (published): filtered to 0.2 µm; bottled and double-bagged in a cleanroom; gamma-irradiated to SAL 10⁻⁶; sterility tested via USP 14-day sterility test; bacterial endotoxin testing prior to release.
• Traceability package: manufacturer states each case includes lot-specific documentation detailing QC, irradiation, sterility, and bacterial endotoxin limits; manufacturer also notes a QR code on each case linked to lot documentation.
• Case configuration: 12 × 16 oz trigger spray bottles per case (sold as a case on SOSCleanroom).
• Hazmat/shipping note: the SOSCleanroom listing notes consumer commodity/ORM-D restrictions and ground shipping only.
• Country of origin: not stated in the SOSCleanroom listing or the manufacturer documents included in the Source basis.

The fastest way to “fail” alcohol disinfection is to let it flash off before the required contact time. In practice, teams often spray, wipe once, and move on—especially on large surfaces. Use a method that controls coverage, wet time, and wipe discipline.

• Contact time collapse: spraying a warm surface once and immediately wiping dry (surface is never wet long enough to meet the published 5–10 minute contact times).
• Cross-contamination wiping: using one saturated wiper for an entire bench, then “finishing” with the same face (redistributing bioburden/particulates).
• Using alcohol as a heavy-soil remover: it can smear oils/soils; pre-clean is often required for reliable disinfection performance.
• Improper storage: storing above the manufacturer’s published maximum temperature or near heat sources; increased evaporation and container stress can follow.
• Uncontrolled “mixing” behavior: combining with other chemistries on the same surface without validated sequencing (risking reduced efficacy or residue issues).

In sterile alcohol programs, most products converge on similar basics (0.2 µm filtration, cleanroom packaging, terminal sterilization). The practical differentiators are documentation completeness, ergonomic delivery, wet contact-time labeling, and how consistently lots behave in your process.

• Veltek STER-AHOL WFI — sterile 70% denatured ethanol options marketed for classified environments; commonly positioned with WFI blending and EPA registration.
• Ecolab Life Sciences sterile alcohols — sterile alcohol ranges that include denatured ethanol blends (often WFI/DI options) and multiple delivery formats.

Sanihol ST is aligned to controlled environments that demand sterile handling and documentation: cleanroom bottled, double-bagged, gamma irradiated to SAL 10⁻⁶, and supported with lot-specific documentation. It is commonly selected for sterile areas where teams prefer not to decant bulk alcohol, and where endotoxin control matters for product-contact-adjacent surfaces.

Decon Laboratories markets Sanihol ST as an EPA-registered disinfectant and emphasizes a WFI-quality endotoxin limit criterion alongside sterility and irradiation documentation. For users, the “fit” is strongest when your program explicitly requires sterile alcohol, traceability paperwork, and published wet contact times—and you have a separate strategy for spore control when needed.
