BeNat Pets. All-Natural Furry Pet Soap Bar. 5.8 oz.

A handmade pet soap bar built around coconut oil, vegetable glycerin, and lavender, eucalyptus, and citronella oils. The full ingredient list is short and disclosed: vegetable glycerin, coconut oil, palm oil, lavender oil, sodium hydroxide, stearic acid, water, Indian lilac leaf extract, eucalyptus leaf extract, citronella, and eucalyptus leaf oil. No synthetic dyes, parabens, phthalates, or synthetic sulfates. Made by hand in small batches in Colombia, with a 3–4 week cure time per bar.

A few honest trade-offs: palm oil is in the formula — a common soap-hardening ingredient with a complicated sourcing record, and no certification (RSPO or otherwise) is listed for it. Packaging details are not disclosed by the vendor. At end of life, a used-down soap bar can go in a home compost bin; any wrapper should be checked against your local guidelines. Marketed as flea-preventive — that claim is not evaluated by the FDA or EPA, so treat it as anecdotal.
