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 Bronzers
Chemical Name
Why it’s harmful
Talc
Talc, a naturally occurring mineral, is commonly used in cosmetics and personal care products for its moisture-absorbing, smoothing, and anti-caking properties. It is also utilized in food products and animal feed. However, some talc may be contaminated with asbestos fibers, which are linked to cancer. This contamination occurs due to the proximity of talc deposits to asbestos mining sites. Health concerns associated with talc include irritation, cancer risks, and potential organ system toxicity.
Calcium Silicate
Calcium Silicate is a clay-like ingredient commonly found in cosmetics and personal care products such as bath products, makeup, and skin care items. Its various uses in cosmetics include serving as an abrasive, opacifying agent, viscosity-increasing agent, anticaking agent, emulsion stabilizer, binder, and suspending agent.
Potassium Sorbate
Potassium sorbate, a white crystalline or powder compound with a distinctive odor, is widely used as a preservative and antimicrobial agent for foods, cosmetics, and pharmaceuticals, and occasionally as a medication. For human exposure, it's usually not a primary irritant nor a sensitizer at concentrations up to 0.5%. A few reported cases involve individuals with specific intolerances, evidencing contact urticaria and pseudo-allergy. From the perspective of animal studies, Potassium sorbate generally shows negligible toxicity for rats, mice, and rabbits. While mixed results emerged for mutagenic tests, no instances of neoplasm formation or teratogenic effects were reported when rats consumed 0.1% potassium sorbate in their diet or 0.3% in their water for up to 100 weeks.

Silicon Dioxide
Silica, also known as silicon dioxide with the formula SiO2, occurs in many forms that have the same chemical composition but differ in atomic arrangements. These forms are categorized into two groups: crystalline silica (c-silica) and amorphous silica (a-silica). The difference lies in their structure; c-silica has repeating patterns of silicon and oxygen, while a-silica structures are more random. All silica forms are odorless solids that form non-explosive dust when suspended in the air. Additionally, silica can react with other metallic elements and oxides to form silicates.
Bismuth Oxychloride
Bismuth oxychloride, a natural mineral, is utilized as a makeup colorant to create an iridescent effect but can cause skin, eye, and respiratory irritation. The FDA permits its use in coloring cosmetics and personal care items, except for lip products, without certification.
