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 Bath Salts
Chemical Name
Why it’s harmful
Butylparaben
Butylparaben, a chemical used in various products, has been shown to cause skin irritation in humans and potential sensitization in dermatitis patients. Animal studies indicate that it has low to moderate oral toxicity and can cause damage to the liver, spleen, and thymus. It can also lead to cell proliferation in rats' stomachs, though it was not found to be carcinogenic or mutagenic. However, it may negatively impact sperm viability and activity, as demonstrated in different in vitro and in vivo studies. Lastly, it proposed weaker aquatic toxicity compared to parabens with longer alkyl chains, but still showed estrogenic effects in certain fish species.
Ethylparaben
Ethylparaben is a chemical used as a preservative in various products including pharmaceuticals, cosmetics, and adhesives. It exhibits low toxicity in humans and animals, but can cause skin irritation, particularly when applied to damaged skin, and may worsen pre-existing skin conditions. Despite causing cell proliferation in rats' forestomachs and chromosomal aberrations in a hamster ovary cell test, it has shown no evidence of causing cancer. However, it was found to be toxic to fetuses at doses toxic to the mother, though it did not cause malformations (nonteratogenic). Interestingly, while it impacted sperm viability in lab conditions, it showed no negative effects on mouse sperm in actuality.

d-Limonene
d-Limonene is a liquid with a lemon-like smell, often used as a solvent to substitute for more volatile and toxic organic solvents. When it comes into contact with air, it can oxidize, and this oxidized form is a known skin sensitizer, capable of irritating skin and eyes. The combination of d-limonene and l-limonene is known as limonene or dipentene. The estimated lethal dose for humans is between 0.5 to 5 g/kg, and studies have shown that it can cause diarrhea and liver effects when ingested in high doses.
Linalool
Linalool is a naturally occurring terpene alcohol found in many flowers and spice plants, consisting of two enantiomers. It is widely used in commercial products for its pleasant floral and spicy scent, serving as a key ingredient in soaps, fragrances, food flavors, household products, and insecticides. In plants, linalool functions as a metabolite, volatile oil component, antimicrobial agent, and aroma compound. Acute exposure to linalool can lead to central depressive effects with symptoms such as ataxia, reduced motor activity, and respiratory disturbances. Additionally, inhalation, oral intake, or skin absorption can result in irritation, pain, and allergic reactions.
