The Question
“I’m a bit cautious of products containing certain ingredients. These products are just for me, but I’m a bit worried they might be toxic to my cat, Karlsson. Prunus Armeniaca Kernel Oil (abrikoskerneolie), and little amounts of Rosmarinus Officinalis Leaf Oil. Thanks!” – Daniel
Quick Info about Karlsson
Hi Daniel,
You are absolutely right to be cautious, as many everyday products that are harmless to us can pose risks to cats. Apricot kernel oil (Prunus armeniaca kernel oil) in cosmetic or skincare products is generally not toxic to cats. The concern with apricot kernels themselves is amygdalin, a compound that can release cyanide, but cosmetic-grade oils are purified and safe for topical use. Unless Karlsson were to directly ingest a large quantity of the oil, the risk from incidental exposure is very low.
Rosemary essential oil (Rosmarinus officinalis leaf oil) requires more care. Rosemary, as a herb, is considered safe, but the essential oil is highly concentrated. Cats lack some of the liver enzymes needed to metabolize compounds in essential oils, so exposures beyond simple contact can lead not only to local irritation but, in higher doses, to more serious effects such as drooling, vomiting, tremors, or even liver injury. In cosmetic products for human use, the amounts are typically very small and unlikely to cause harm unless Karlsson licks the product directly from your skin. The greatest risk comes from undiluted oils, diffusers, or if such products are applied directly to a pet.
The safest approach is to continue using your products yourself but avoid letting Karlsson lick or groom areas where the product has been applied, and ensure he has access to well-ventilated spaces. If you ever notice signs such as drooling, unsteadiness, or vomiting after possible exposure, seek veterinary attention right away. For everyday peace of mind, teletriage veterinary services can be a useful resource to help assess risks quickly in non-emergency situations.
Best,
Dr. Paola
