kin+Kind Flea/Tick Lavender Shampoo
Lower concern; pet shampoo with no known PFAS triggers, but brand offers no explicit PFAS commitment.
Kin+Kind's flea/tick lavender shampoo is a liquid cosmetic with no apparent water-repellent, grease-resistant, or non-stick coatings, the main vectors for PFAS in personal care. The brand makes no PFAS disclosure one way or the other.

The full breakdown
What it's made of and why it matters
Kin+Kind Flea/Tick Lavender Shampoo is a water-based concentrate formulation designed for topical pet use. The active ingredients are likely natural or botanical extracts (lavender noted in name), not synthetic pyrethroids or organophosphates common in conventional flea treatments. Water-based formulations carry lower volatility risk than oil or alcohol-based concentrates, meaning less likelihood of inhalation exposure during application or storage.
The brand's record and disclosure
Kin+Kind markets itself as a natural, eco-conscious pet care brand but does not publish detailed ingredient safety data sheets or third-party certifications (e.g., EWG Verified, Leaping Bunny) on this product. No known recalls or safety controversies are on record for this specific shampoo. The brand remains silent on PFAS use or commitment, which is typical for smaller natural pet brands but limits transparency.
How it compares in its category
Pet shampoos span a wide spectrum from synthetic pesticide-based treatments to botanical concentrates. This product sits in the natural/botanical segment, positioning it as a gentler alternative to chemical flea treatments; however, efficacy claims for natural ingredients are not established at the same level as prescription or OTC synthetic alternatives. Concentrate formulations require dilution, which reduces packaging waste compared to ready-to-use bottles, though disposal of empty containers depends on local recycling infrastructure.
If you buy it
Follow dilution instructions precisely; over-concentration may cause skin irritation in pets. Store the concentrate in a cool, dark place away from direct sunlight to preserve botanical ingredient potency and prevent degradation. Perform a patch test on a small area of your pet's skin before full-body application to rule out individual sensitivity or allergic reaction. Do not allow the product to contact eyes or be ingested; rinse thoroughly after application. Discard if the product separates, smells off, or shows signs of microbial growth.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Formaldehyde releasers (preservatives)
Water-based shampoo concentrates typically require preservatives to prevent bacterial and fungal growth. While no specific formaldehyde-releasing preservative (e.g., DMDM hydantoin, imidazolidinyl urea) is confirmed in the product, these are common in the category. Check ingredient label for DMDM hydantoin, diazolidinyl urea, or bronopol; if present, risk is low but relevant for sensitive pets.
Fragrance/essential oil allergens (lavender noted)
Lavender essential oil is a known allergen and irritant in some individuals (both human and animal). Pet shampoos with essential oils carry risk of contact dermatitis, ear irritation if not rinsed thoroughly, or ingestion irritation if pet licks paws post-application. Risk is higher if concentrated; dilution reduces it but does not eliminate it.
Undisclosed botanical extract contaminants
Natural ingredient sourcing is not independently verified on public records. Botanical extracts can contain pesticide residues, heavy metals (if sourced from contaminated soil), or microbial contaminants if not adequately processed. Kin+Kind does not publish supplier or testing certifications for this product.
Microbial growth in concentrate (if mishandled)
Water-based concentrates are prone to bacterial and fungal colonization if diluted and stored improperly (e.g., in warm, humid bathrooms) or if opened repeatedly without proper sealing. Risk is manageable with proper storage but should be monitored, especially in humid climates.
Packaging leachables (container material)
No specific packaging material or notable leaching issues are on record for Kin+Kind bottles. However, if the concentrate is stored in PET plastic, exposure to heat or sunlight over time could theoretically release trace amounts of acetaldehyde, though this is not an established concern for this product.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
