Our Product Rating System
First, Camille (co-creator of Welpr) hand picks cleaner product options from a variety of sources.
Next, we collect information about each product's safety, consumer satisfaction, and eco-ethical standing.
Finally, we run all this information through an algorithm that calculates the Welpr Rating.
Welpr Rating:
5.0/5
Part 1: Product safety
We evaluate safety information from 3rd party organizations (e.g. EWG, Made Safe, etc.). Instead of relying solely on any one of these companies for safety information, we assess all of them.
Part 2: Consumer satisfaction
We scour the web for consumer ratings and reviews to verify products are not only cleaner options, but also effective. Products can either be Above Average, Average, or Below average for their respective category (e.g. cleaning products).
Part 3: Ethics & Environment
When you buy a product, you’re supporting that company with your dollars. We believe it’s important to support ethical companies, so we pool together certifications that verify a company's ethics and environmental impact.
Common Harmful Chemicals in Shower Caps
Chemical Name
Why it’s harmful
Bisphenol A
Bisphenol A (BPA) is a solid used in manufacturing epoxy resins and polycarbonates for food packaging. Human exposure to BPA can cause allergic dermatitis and has been associated with negative effects on fertility, such as declined semen quality, increased sperm DNA damage, and risk of miscarriage. BPA, an endocrine disruptor, also affects oocyte quality during in vitro fertilization. Animal studies indicate that BPA caused eye damage in rabbits, accelerated tumorigenesis in mice, disrupted sex behaviors in rats, and induced obesity in rodents. Ecotoxicity studies show BPA's disruptive effects on sex characteristics in fish and gene expression in Arabidopsis thaliana, suggesting broad environmental implications.
