Studies/Research

During the early phases of the valPure V70 ideation, Sherwin-Williams developed and adopted the 7-step Safety by Design process. Safety by Design incorporates a variety of testing including studies intended for global regulatory compliance and hypothesis-driven scientific research to promote innovation.

Regulatory compliance studies are performed by contract research organizations in accordance with widely accepted guidelines under good laboratory practice (GLP) conditions. These studies include toxicology testing of acute, sub-chronic, and chronic toxicology; reproductive and developmental toxicology; genotoxicity and mutagenicity; ecotoxicology; and environmental fate studies. Often the results from regulatory studies are presented and disseminated as study reports.

To accompany regulatory compliance studies, Sherwin-Williams supports hypothesis-driven scientific research to promote innovation of the valPure V70 technology. This research is primarily conducted by academic institutions who are given full autonomy. Sherwin-Williams supported research includes further investigation into specific pathways including endocrine activity, immune system modulation, and environmental impact. These research studies are published in reputable peer-reviewed journals.

As a commitment to transparency, Sherwin-Williams has made all study reports and scientific research publications available via links which are provided below. The collection of study reports and scientific publications represents more than a decade’s worth of V70 research and development.
