TechNotes

To provide a better understanding of some of the issues in the selection, use and testing of our cleanroom consumables, Texwipe has developed a number of Technical Notes, aka TechNotes.

Topics include wiper consistency, cleaning of isolators, sterility validation, cleanbuild protocols, particle testing and cleanroom stationery. Much additional information on specialized topics in contamination control can be found in the Published Papers section of the Texwipe Library.

We welcome feedback on these Technical Notes. If you have comments or questions, or feel that there are other topics that you would like to see developed as Technical Notes or publications, please contact us with any questions or feedback.

ALCOHOLS (Isopropyl Alcohol, Denatured Ethanol)

TechNote Title	Description
In-Use 70% Isopropyl Alcohol Level	A study monitoring in-use 70% Isopropyl Alcohol Level using a specific gravity method test.
70% Isopropyl Alcohol Sterility In-Use	A study monitoring 70% Isopropyl Alcohol Sterility In-use
Bags Used as a Component	Integrity Test Results for Bags Used as a Component of Sterile 70% IPS, TexQ Disinfectant and TexP peroxide Solutions.
In Use 70% Ethanol Percentage Level in a Denatured Alcohol Solution	A study monitoring the in-use 70% ethanol percentage in a denatured alcohol solution. Conclusion: Texwipe's 70% Denatured Ethanol solution may be used for at least 28 days without concern for the percent ethanol concentration changing.
Denatured Ethanol Solution Sterility in Use	A study monitoring the sterility of Denatured Ethanol solution in use. Conclusion: Texwipe 70% Denatured Ethanol solutions may be used for at least 30 days without concern for thier sterility change.

WIPERS

TechNote Title	Description
Microdenier Wipers in Critical Cleaning Applications	Microdenier wipers are increasingly gaining acceptance for use in cleanroom environments because of their ability to perform well in critical cleaning applications.
Consistency As A Measure of Wiper Quality	Wipers are used to control contamination in cleanroom environments in a variety of industries, from building the next-generation microchip to manufacturing the newest vaccine. Each of these settings may have different applications for a cleanroom wiper, but measuring the wiper quality should always be the same, i.e. consistent.

STERILE PRODUCTS

TechNote Title	Description
Packaging Shelf Life	Sterile Dry Wipers, Package Integrity Testing for Shelf Life Determination (Header Bags)
Sterile Validation	Texwipe Sterile Products, Sterilized, Validated, Documented and Endotoxin Tested

SWABS

TechNote Title	Description
Swabs for Cleaning Validation in Pharma	Swabbing is the preferred method to validate critical cleaning within pharmaceutical manufacturing environments. As a result, the selection of a quality swab and a validated swabbing method is critical to producing sensitive, accurate, and repeatable results.
