  • Food-grade ingredients with no artificial dyes, flavors, or sweeteners
  • No sulfates, parabens, PEGs, or triclosan
  • Full transparency with every ingredient clearly disclosed

Not all products in this category are Welpr Approved, but they’re safer than most. The ones that meet our full standard will have the Welpr Approved tag. View our full standards here.

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 Retainer 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.

Peroxydisulfate

Persulfates are inorganic salts commonly used in hair bleaches and hair lighteners in cosmetics. They act as oxidizing agents to accelerate the bleaching process. The safety of these persulfates has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel, which concluded they are safe for brief use followed by thorough rinsing from the hair and skin.

Boric Acid

Boric acid, in the form of white crystals or powder, acts as a cosmetic preservative due to its astringent properties, which deter bacteria formation and contamination in skincare and personal care products. The Expert Panel for Cosmetic Ingredient Safety has assessed the safety of sodium borate and boric acid, concluding that concentrations up to 5% are safe as cosmetic ingredients, but they should not be used on infant or injured skin.

Hey, I’m Camille—co-creator of Welpr and your go-to guide for all things clean living. 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 built Welpr to make that journey feel a bit easier.  When I’m not working on Welpr, you’ll usually find me in the sauna, sipping a raw milk latte while doing a puzzle, or walking with my pit bull Romeo in my hometown of Austin, TX.
