Question:
I bought an unfamiliar brand of tooth whitening strips (to be worn on teeth directly) was wondering if the ingredients are kosher.
The following ingredients are listed: PVPK30, Glycerin, Hydroxypropyl cellulose, PVPK90, Auqa, Alcohol, Hydrogen Peroxide, Menthol.
Thank you
Answer:
Thank you for your question.
In consultation with a kashrus professional, the whitening strips would need a reliable hechsher, because of it’s ingredients, and possible bvecause of the machinery.
Best wishes
