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 Dental Floss
Chemical Name
Why it’s harmful
Polytetrafluoroethylene
Polytetrafluoroethylene (PTFE), commonly found in cosmetics, particularly anti-aging products, is favored for its smooth finish. PTFE is trademarked as Teflon® and is also used in non-stick cookware. However, concerns have arisen due to its fluorinated nature, linking it and similar compounds to delayed menstruation, delayed breast development, and cancer. These ingredients can be found in various cosmetic products like foundation, pressed powder, bronzer, blush, eye shadow, mascara, shave gel, lip balm, and anti-aging lotion.
Perfluorooctanoic Acid (PFOA)
Perfluorooctanoic acid (PFOA) is primarily used to create salts that aid in the processing of producing fluoropolymers and fluoroelastomers. It also acts as a surfactant in firefighting foams, an intermediate in creating fluoroacrylic esters, and a crucial aspect in manufacturing Teflon and similar chemicals. However, exposure to PFOA can lead to adverse health effects, including alterations in thyroid hormone levels, lower fertility, an increased risk of cerebrovascular disease, higher cholesterol and triglyceride levels, a possible link to ADHD, smaller abdominal circumference and birth length in infants, an increased risk of common cold and gastroenteritis in children, and potentially prostate cancer mortality. Studies on animals have indicated possible liver and brain dysfunction, carcinogenicity, and reproductive and developmental toxicity. Ecotoxicity studies found alterations in genes linked to lipid metabolism, hormone action, immune responses, and mitochondrial functions in rare minnows exposed to PFOA.
Perfluorooctane Sulfonic Acid (PFOS)
Perfluoroalkyls are synthetic chemicals known for their ability to resist oil, grease, and water, primarily used in surface protection products and fire-fighting foams. The two most abundant perfluoroalkyls are perflurooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). Studies have observed liver enlargement and elevated cholesterol in animals given high doses, and the presence of PFOS in various populations has raised environmental and health concerns, leading to the phase-out of some PFOS-based chemicals. Tests have shown a range of health effects in animals, including eye irritation, liver changes, teratogenic effects, and more, with no evidence of mutagenicity. However, no substantial link has been found between PFAS concentrations and increased cardiometabolic risk measures in human studies, and there are no known health effects from exposure when used as intended.
Phthalate
Phthalates, linked to endocrine disruption, reproductive toxicity, and cancer, are banned in the European Union but remain prevalent in U.S. cosmetics. They are widely used in personal care products, such as nail polish, fragrances, and eyelash glue and other products. A significant loophole allows phthalates to be added to fragrances without disclosure. Health concerns include endocrine disruption, developmental and reproductive toxicity, and potential carcinogenicity.

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.
