At Queen of the Thrones®, your well-being is our number one priority. Period. End of story.
We stand behind every drop of our 100% organic, cold-pressed, hexane-free, practitioner-curated Castor Oil — and we take quality, purity, and transparency seriously.
Recently, Mamavation published an article claiming that their lab testing found phthalates in Queen of the Thrones® Castor Oil. We want to address this claim openly, share the facts, and reassure our customers that you can trust the safety and integrity of our products.
What Did Mamavation’s Article Say?
Mamavation conducted a one-time consumer test, sending 10 Castor Oil products (including ours) to an EPA-certified lab to screen for phthalates. They reported that Queen of the Thrones® Organic Golden Castor Oil showed a total sum of 270 ppb phthalates, placing it in their “Better Castor Oil” category — meaning intermediate contamination levels compared to other brands.
While we appreciate consumer watchdog groups raising awareness of potential contaminants, we respectfully disagree with the conclusions drawn about our product and want to provide the full picture.
What Our Independent Testing Shows
At Queen of the Thrones®, we don’t rely on a single test or a single lab. We use ongoing functional testing across every major production batch, backed by independent, accredited third-party labs.
Our recent phthalates testing (by EPA- and ISO-accredited labs such as Qalitex, SGS, and PhytoChemia) shows:
-
Not Detected (ND) levels for all major phthalates, including DEHP, DBP, DINP, DCHP, and others.
-
Verified across three batches, not just a one-time sample (see our Full Transparency Page, which includes downloadable PDFs of our test results, for all the details).
-
Aligned with industry best practices and regulatory safety standards.
We also bottle exclusively in amber glass (not plastic) and ensure a tightly controlled supply chain, minimizing any risk of plasticizer or packaging contamination.
Why the Results May Differ
While Mamavation’s test was conducted with good intentions, it reflects a single consumer spot-check. Results like these can vary due to several influencing factors, including potential:
-
Cross-contamination within testing facilities or the lab method used
-
Environmental background levels, especially at ultra-trace detection limits
-
Sample handling after production, including storage, shipping, or retail exposure
-
The growing concern of counterfeit and imitation products sold on online marketplaces
At Queen of the Thrones®, a more comprehensive approach is taken. Multi-batch, multi-lab testing protocols are followed to ensure consistent quality, purity, and safety—providing a deeper and more accurate understanding of the oil.
Just as a functional health practitioner would assess the full thyroid panel—not just TSH—Castor Oil is also evaluated with a holistic lens. It's never just about a single marker. True quality is about how all elements work together, in harmony.
This Functional Testing approach reflects a deeper philosophy: caring for the oil as a precious gift from nature, and ensuring it can care for you in return. It’s what sets Queen of the Thrones® apart in the world of clean beauty and self-care.
Our Request to Mamavation
We respectfully invite Mamavation to review the independent lab evidence we provide, update their article to reflect our verified Not Detected (ND) phthalate results, remove Queen of the Thrones® from their “contaminated” lists, and elevate Queen of the Thrones® to the top of the BEST CASTOR OIL section of their article correctly stating “0 ppb total sum phthalates.”
We are committed to scientific transparency and would be happy to engage directly to clarify any data or testing details.
Our Commitment to You
We promise to continue:
-
Conducting thorough, multi-batch, independent functional testing
-
Publishing full test results on our Full Transparency Page
-
Upholding the highest standards of product purity, safety, and trust
Thank you for being part of the Queen of the Thrones® family. If you have questions, concerns, or want to review our independent lab reports for yourself, please contact us here — we’re always happy to share.
