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 Contour Stick
Chemical Name
Why it’s harmful
Disteardimonium Hectorite
Disteardimonium Hectorite is a versatile ingredient in cosmetics, functioning as a light stabilizer and viscosity controller. It is derived from natural smectite clay and chemically modified for compatibility with formulations. Its primary role is to provide stability, enhance texture, and prevent ingredient separation in cosmetic products, including creams, lotions, gels, foundations, and eyeliners. While generally safe, it can potentially cause skin irritation or rare allergic reactions in individuals with sensitivities or allergies.
Propylene Carbonate
Propylene carbonate, a colorless liquid, is principally used in paints, the pigment and dye industry, and lithium batteries. Human exposure in studies has demonstrated that it can cause moderate skin irritation in its undiluted form, although in diluted form (5 to 10%) and as a component in cosmetic products (0.54 to 20%), it presents no skin irritation. Some products containing propylene carbonate were found to be non-phototoxic, with one potentially causing a low-level photoallergic reaction. Animal studies reveal minimal irritation to skin and eyes. No significant toxic effects were found in rats subjected to high concentrations over an extended period, though some maternal toxicity was observed. Tests also show propylene carbonate is negative for mutagenicity and genotoxicity.
Triethoxyoctylsilane
Triethoxycaprylylsilane is a clear-to-yellow liquid with various functions in cosmetics, including acting as a binder, skin conditioning agent, and surface modifier. Trimethylsiloxysilicate is considered safe for skin and hair at lower concentrations, but it should not be ingested as it can be toxic. A patch test is advisable before full application, especially for individuals with highly sensitive skin.
Butylene Glycol
1,3-Butanediol is a colorless, viscous liquid used in the manufacturing of polyester plasticizers and as a mold inhibitor. It does not irritate human skin or mucous membranes but can cause severe stinging in the eyes, quickly relieved by water. Animal studies showed it has low acute oral toxicity in rodents with no major toxic effects observed. However, when used as an energy source in replacement of carbohydrates, it had central nervous system effects on rats, dogs and calves and decreased glucose while increasing beta-hydroxybutyrate in lactating goats. Also, it was found to be fetotoxic in rats during pregnancy, hinted at reduced male fertility, yet showed no genotoxic effects.
Mica
Mica, a natural mineral dust, is commonly used in makeup, cement, asphalt, and electric cable insulation. It is a color additive in cosmetics and provides a shimmer effect in foundations. Workers exposed to mica, especially in muscovite mills, face health risks like respiratory problems and lung scarring from long-term inhalation. Labels may list "Mica" or "Muscovite." Regulatory agencies have established exposure limits for worker safety.
Pentaerythrityl Tetra Adipate
Pentaerythrityl Adipate/Caprate/Caprylate/Heptanoate is a mixed ester compound derived from pentaerythritol and various acids such as adipic, capric, caprylic, and heptanoic acids. This ingredient is commonly found in products like lipstick, foundation, blush, bronzer/highlighter, and lip balm.
Calcium Aluminum Borosilicate
Calcium aluminum borosilicate, a glass-type material, serves as a bulking agent in the cosmetics and personal care industry. It enhances volume and texture in formulations, generally considered safe with low toxicity and no known cancer-causing properties. Although it's generally safe, individual sensitivities can differ, so patch tests are recommended for those with allergies. Regulatory classification includes a possibility of being carcinogenic and possibly toxic to reproduction, but it is deemed safe for cosmetic use, with concentration or use restrictions.
Alpha-Tocopherol Acetate
Tocopheryl acetate is a compound composed of acetic acid and tocopherol (vitamin E). Alpha-tocopheryl acetate (ATA), a specific form of vitamin E, is commonly found in skincare products and dietary supplements. It is used in various cosmetics and personal care items, including lipstick, eye shadow, blushers, face powders, moisturizers, bath soaps, hair conditioners, and more.
