Bests & Worsts Reviews from Amazon

I have been a Massage Therapist for 20+ years and have been using Jojoba Oil for at least 10 of those years, one of the main reasons being that it rinses cleanly from the sheets. This oil was well priced so I purchased it. I find it pleasant to use although thicker in texture than I'm used to. I started to notice in a short amount of time that my sheets are becoming badly oil stained indicating to me that this is not true Jojoba Oil. Fraud alert on the claims that this is 100% Jojoba. How can this be tested? Does anyone know? I placed a call to the company but received a voicemail. I left my concern on the message and did not receive a callback.
