In real cleanroom operations, the biggest risk with “routine” solvent wiping is not the chemistry—it is the handling. The moment a bulk pail gets opened on a bench, you create opportunities for particulate ingress, cross-contact, and inconsistent wetting (too dry to lift residue, or so wet it floods seams, fasteners, and crevices). TX161 is designed to reduce those day-to-day process variables by combining a prefilled, filtered 100% IPA solution with a ready-to-use, non-atomizing adjustable sprayer and double-bag packaging for controlled introduction into critical areas.

SOSCleanroom supports Texwipe programs because documentation discipline and lot traceability matter in audits and investigations. When your deviation record needs to answer, “Which solvent lot touched this tool, this cart, or this enclosure?”, that is not a theoretical question—it is a common root-cause path.

• Surface cleaning and residue removal where a fast-evaporating solvent is preferred.
• Wipe-down of items entering controlled spaces (e.g., pass-through staging, carts, bins, notebooks, phones, and tool cases).
• Critical cleaning workflows that benefit from controlled dispensing instead of pouring from pails or drums.
• Use with low-lint cleanroom wipers when you need consistent wetting and repeatable wipe technique.

• 0.2 µm filtered solution for cleanliness-focused solvent use.
• Double-bag packaging to reduce handling contamination during gowning-room transfer and staging.
• Non-atomizing adjustable spray supports controlled application (stream for precision; coarse spray for broader coverage).
• Ready-to-use, fully assembled sprayer reduces assembly steps that can introduce particles or cross-contact.
• Lot-coded with expiration date to support traceability, receiving controls, and investigation timelines.
• Case configuration (12 × 16 oz trigger spray bottles) supports point-of-use stocking without decanting from bulk containers.

TX161 is a prefilled 16 oz (473 mL) trigger-spray bottle containing 100% isopropyl alcohol solution intended for critical cleaning and controlled dispensing. The solution is described as being filtered through a 0.2 µm filter and filled into cleaned containers that are double-bagged for contamination control. Each bottle is lot coded and marked with an expiration date for recordkeeping and receiving traceability.

Note on alcohol grade terminology: Texwipe’s IPA technical data sheet describes 100% isopropanol solutions as semiconductor-grade isopropanol and lists TX111/TX161 under that category. The SOSCleanroom product description includes a “USP-grade isopropyl alcohol” feature bullet while also describing the contents as semiconductor-grade isopropanol. If grade is a release-critical requirement in your facility (e.g., microelectronics vs. general controlled environment cleaning), confirm acceptance criteria in your internal material specification and verify against supplier documentation at time of receipt.

The table below captures what matters at the bench: container format, packout, filtration, and traceability attributes that drive real-world consistency.

100% IPA is typically selected when fast evaporation and low residue are critical for visual finish, optical clarity, and tight process timing. The practical tradeoff is that it can flash off quickly, so wipe technique (maintaining a wet edge and controlling re-deposition) matters more than many teams expect.

Cleanroom environment guidance in the Texwipe IPA technical data sheet lists non-sterile IPA solutions for ISO Class 5–8 use cases, supporting controlled environments where sterility is not required but cleanliness and documentation still matter. If your process is aseptic, sterile fill, or requires sterile disinfectant intent, use a sterile solution validated for that purpose and aligned to your environmental monitoring and cleaning validation program.

• Packaging: Double-bagged for extra contamination control; case unit is 12 poly bottles (16 oz trigger spray bottles).
• Sterility: Non-sterile. (If you need sterile, Texwipe’s sterile 70% IPA family is separately designated.)
• Traceability: Lot coded; expiration date marked on each package for QA tracking and receiving controls.
• Shipping controls: The SOSCleanroom listing flags this as a Consumer Commodity ORM-D shipment with ground shipping only; plan replenishment lead times accordingly.
• Country of origin: Not stated in the SOSCleanroom product page, Texwipe product page, or the linked TDS/SDS in the source basis.

A high-performing solvent can still produce poor outcomes if it is applied inconsistently. The most repeatable approach is to control three variables: (1) where the IPA goes, (2) how the wipe contacts the surface, and (3) what happens at edges, seams, and “last passes” where residue re-deposition is most common.

If you are using IPA as part of a regulated cleaning program, align your acceptance criteria to your validation logic (surface type, residue risk, inspection method, and allowable NVR/ionic load). The “right” IPA is the one that supports your documented process controls, not the one that merely evaporates quickly.

• Streaking or haze: Often caused by wiping with a contaminated or overloaded wipe face, or by letting dissolved residue dry at the wipe boundary.
• Overspray into crevices: Spraying directly onto complex assemblies can drive solvent (and dissolved residue) into seams and under fasteners where it reappears later.
• Nozzle cross-contact: Touching the nozzle to a surface transfers contaminants to the dispenser path and can spread them across future wipe-downs.
• Flash-off before cleaning: 100% IPA can evaporate quickly, especially under high airflow. If the wipe is too dry on contact, cleaning effectiveness drops.
• Safety noncompliance: Using IPA near ignition sources, without ventilation, or without appropriate PPE can create preventable incidents and documentation findings.

Competitors for non-sterile 100% IPA typically differentiate on filtration, packaging discipline (double-bagging), traceability, and whether the product is purpose-built for cleanroom introduction versus general lab solvent use. When comparing alternatives, focus on how the product is filled, how it is packaged, and whether lot/expiration traceability is standard—not optional.

• Cleanroom-packaged 100% IPA trigger sprays from other contamination-control suppliers: Often comparable in format, but verify double-bag packaging and the supplier’s lot documentation package.
• General laboratory 100% IPA in spray bottles: Typically lacks cleanroom-specific packaging and may not include the same contamination-control handling or documentation expectations.
• Bulk pails/drums of IPA with in-house decanting: Can be cost-attractive, but frequently increases contamination risk and introduces variability in filtration, transfer, and dispenser cleanliness.

TX161 aligns well with controlled environments where cleanliness and traceability are required but sterility is not. The Texwipe IPA TDS lists non-sterile IPA solutions for ISO Class 5–8 use, supporting common workflows in microelectronics, optics, aerospace assembly, and controlled manufacturing where residue removal and fast dry-down are process-critical.

If your environment or procedure requires sterile application, validated sporicidal performance, or disinfectant intent, a non-sterile 100% IPA trigger spray is not the right control. In those cases, match the solution to your classification, cleaning validation strategy, and audit expectations, then standardize receiving criteria (lot, expiration, packaging integrity, and documentation completeness).
