Decon SaniHol® ST 8116 Sterile 70% Denatured Ethanol Solution (16 oz Trigger Spray) — 12/Case
SaniHol ST 8116 is a sterile, ready-to-use 70% (v/v) denatured ethanol solution designed for controlled-environment cleaning and
disinfection where teams need sterile packaging, lot documentation, and repeatable use claims. The product is
0.2 µm filtered, bottled and double-bagged in a cleanroom, and gamma-irradiated to SAL 10−6.
Each lot is tested prior to release using a USP 14-day sterility test and bacterial endotoxin (LAL) testing with a stated
endotoxin target aligned to WFI limits (< 0.25 EU/mL). The 16 oz trigger format is commonly selected to avoid decanting and to keep
daily use aligned to validated, documented handling.

1) Where sterile denatured ethanol fits (and where it does not)
In many contamination-control programs, alcohol is an “every-shift” tool due to fast evaporation and practical coverage for benches, carts, stainless
panels, and equipment exteriors. SaniHol ST 8116 is chosen when the task requires a sterile alcohol with strong documentation controls (cleanroom
packaging, terminal sterilization, and lot-level sterility/endotoxin results) rather than general-purpose non-sterile alcohol.
Important scope note (accuracy-first)
Alcohol solutions are widely used for routine disinfection/sanitation, but they are not sporicides. Spore control typically requires a separate
sporicidal step in a validated rotation strategy (per SOP/CCS).
2) Standards alignment (USP, ISO, Annex 1) — educational reference
USP <797> and USP <800> expect cleaning/disinfection activities to be governed by SOPs that define agents, technique, frequencies,
and PPE. EU GMP Annex 1 reinforces contamination control strategy (CCS), validated cleaning/disinfection, and disciplined operator behavior in Grade A/B.
ISO cleanroom operations guidance supports an operations control program covering personnel practices, cleaning, and material movement.
Key compliance reality: these frameworks do not “approve” a specific alcohol brand. Your site must select, validate, document, and train
on the exact product, wet contact time, and wiping method used in your rooms.
3) What drives real performance: wet contact time + wipe discipline
The most common operational failure with alcohols is contact time collapse: spray once, wipe immediately, and move on. If your SOP uses this product
as a disinfectant/sanitizer step, the execution must preserve full coverage and required wet time.
Published use expectations to align in SOP (verify current label / tech sheet)
- Disinfectant step: minimum 10-minute wet contact time on hard, non-porous surfaces (published guidance).
- Sanitizer step: 5-minute wet contact time (published guidance).
- Technique: apply to achieve full coverage; re-wet as needed in high airflow/warm zones; avoid wiping dry before the required wet time unless your SOP explicitly allows post-contact wipe-off.
4) Composition (why “denatured” matters)
SaniHol ST is a denatured ethanol blend. 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 controls (filtration, cleanroom packaging, irradiation, documentation)
as it is about chemistry.
5) Donning discipline & PPE interface control
In critical environments, deviations often trace to touch events and interface gaps (adjusting eyewear/hoods, contacting non-controlled objects,
poor glove–sleeve overlap). Ensure personnel are fully gowned before introducing sterile alcohols into higher grade areas. Many aseptic programs don
sterile gloves last and sanitize gloved hands with sterile alcohol per SOP.
6) System pairings (validated-program logic)
Sterile alcohol performance in cleanrooms is inseparable from the wiper and PPE system. Final selection must match your ISO class, surface set, residue limits,
and your SOP validation.
7) Common failure modes (what to watch in audits)
- Wet-time failure: spraying and wiping dry immediately (surface never remains wet long enough to meet the required dwell time).
- Cross-contamination wiping: using one saturated wiper face across large areas, redistributing soils/bioburden.
- Using alcohol as a heavy-soil remover: visible soil often requires a pre-clean step; soil load can reduce disinfection performance.
- Unqualified sequencing: mixing chemistries on the same surface without validated order (efficacy/residue risk).
- Storage drift: heat exposure above published limits (accelerated evaporation/container stress).
8) Safety and handling (non-negotiables)
Flammability & SDS control
Denatured ethanol solutions are highly flammable. Control ignition sources, manage hot surfaces, and ensure appropriate ventilation.
Always refer to the current SDS and the manufacturer’s current label/tech sheet for hazards, handling, spill response, and disposal guidance.
