Our Product Rating System

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

The Welpr Rating takes into account 3 things:

  1. Product Safety
  2. Consumer Satisfaction
  3. Ethics & Environment
Product safety

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.

Consumer satisfaction

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).

Ethics & Environment

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 Makeup Brush Cleaner

Chemical Name

Why it’s harmful

Sodium Lauryl Sulfate

Sodium Lauryl Sulfate is recognised as a skin, eye, and respiratory tract irritant according to ICSC. It may cause allergic reactions and eye irritation as stated by the HSDB. Exposure may even result in eye burns, as per CAMEO. Depending on its form - which may range from a solid (90-98% purity), to a paste (30-41%), or an aqueous solution (28-50%) - it can significantly irritate skin and eyes, with adverse effects escalating with increased concentration. Despite these hazards, it is not a skin sensitizer according to CHEMINFO, while eChemPortal: ERMA and MSDSonline endorse its classification as an irritant.

Sodium Laureth Sulfate

Sodium laureth sulfate, derived from ethoxylated lauryl alcohol, is a surfactant used in sudsy products like toothpaste, detergents, and shampoos. While it acts as a cleansing and emulsifying agent, it can sometimes contain toxic impurities such as 1,4-dioxane. This chemical has raised health concerns due to its potential to cause skin, lung, and eye irritation, organ toxicity, and, primarily because of contamination by 1,4 dioxane, cancer.

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.

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.

Methylparaben

Methylparaben is an antimicrobial preservative used in food, drugs, and cosmetics. Some individuals can develop contact dermatitis on skin exposure, and allergic reactions have been reported on ingestion, though the evidence is not conclusive. Data from animal studies suggest that methylparaben is practically non-toxic and non-irritating in normal skin conditions, with high thresholds for observed adverse effects. However, it showed chromosome aberrations in a cell assay and variable results in different uterotrophic assays. An ecotoxicity study found changes in the expression of certain genes at specific concentrations in male medaka, a type of fish.

Propylparaben

Propylparaben is a stable, non-volatile compound utilized as an antimicrobial preservative in food, drugs, and cosmetics. Human exposure can cause sensitization especially if applied to damaged skin and may cause contact sensitivity with high concentrations. Extensive animal studies reveal that propylparaben is relatively non-toxic, yet it can mildly irritate skin, affect sperm counts in substantial levels, and trigger cell proliferation in the forestomach of rats. However, it is not carcinogenic, mutagenic, or clastogenic, and a significant no-observed-adverse-effect level was reported in rats. Ecotoxicity studies show that it can lead to an increase in plasma vitellogenin levels in rainbow trout and a significant decline of vitellogenin production in zebrafish at varying concentrations.

Isobutylparaben

Isobutylparaben belongs to the paraben family of preservatives used in the food, pharmaceutical, and personal care product industries. Parabens mimic estrogen and have been found in breast cancer tumors in some studies. Parabens are commonly found in various personal care products and foods and have been associated with endocrine disruption, skin cancer risk, developmental and reproductive toxicity, and potential behavioral changes in offspring when exposed during gestation.

Isopropylparaben

Isopropylparaben belongs to the parabens family of preservatives utilized in the food, pharmaceutical, and personal care sectors. Parabens have estrogen-mimicking properties and pose a potential risk as endocrine disruptors. Research has detected parabens in the breast cancer tumors of a significant number of studied women, raising concerns about their safety and hormonal effects.

About The Author

Camille May

Hey, I’m Camille, co-creator of Welpr and your clean living guide. After selling my last company in the health food space, I went non-toxic to heal an autoimmune condition. It did wonders for my health, but navigating which products to buy wasn’t easy. We created Welpr to make that journey feel a little bit easier. When I’m not working on Welpr, you can find me at the farmers market or unwinding in the sauna, always in bed at 9pm with a good book. I live in my hometown of Austin, TX with my pit bull, Romeo.
