Purified Cotton Outperforms Greige and Raw Cotton in Lab Study

Print Friendly, PDF & Email

In a recent study on the pharmaceutical properties of cotton, samples were submitted to an independent U.S. laboratory for microbial analysis. A Total Microbial Plate Count and a Mold/Yeast Analysis were prepared for samples of Raw, Greige and Purified cotton. All results were measured in Colony Forming Units per gram.

Microbial Count

The results of the Microbial Count analysis were varied, showing samples in stark contrast to each other. Raw cotton measured 150,000 CFU/gm and Greige cotton measured 40,000 CFU/gm, while Purified cotton had less than 10 CFU/gm. Relative to the other samples, this analysis clearly showed Purified cotton’s benefits as a material resistant to microbial organisms. It also showed that Purified cotton has wide applications and uses in a variety of important industries, including the medical and pharmaceutical industries.

Mold/Yeast Count

Like the Microbial Count analysis, the Mold/Yield Count provided insight into the benefits of Purified cotton. This count revealed that Raw cotton had 2,300 CFU/gm and that Greige cotton had 1,800 CFU/gm. However, Purified cotton was shown to have less than 10 CFU/gm. This further helped illustrate the superiority of Purified cotton compared to other non-purified specimens on the market. When you work with non-purified cottons, there are all sorts of bacteria and fungi that can blunt cotton’s effectiveness.

Types of bacteria, mold and fungi commonly found on non-purified cotton:

  • Enterobacteriaceae
  • Pseudomonas aeruginosa
  • cloacae
  • Staphylococcus aureus
  • Aspergillis
  • Fusarium

Pharmaceutical Standards

Purified cotton has properties that meet or exceed U.S. Pharmacopeia Convention Standards, along with European and Japanese standards. The USP is a scientific non-profit agency that sets standards relating to the strength, quality and purity of medicine, food ingredients and other important goods used throughout the world. Given that Purified cotton meets UPS standards, it’s considered a pharmaceutical grade cotton that is viable for medicinal use.

Purified cotton stood out in the analysis of cotton samples in this study, and it is a more viable option compared to lesser grades of cotton when it comes to medical applications. Purified cotton meets the high standards necessary to be considered pharmaceutical grade, and it outperforms other products on the market.
