We Don’t Just Remove Toxins. We Remove Confusion.
We were never taught to trust our body’s signals—our cycles, symptoms, or sensitivity.
But your body is always absorbing. Always listening.
That’s why we test every batch for hormone disruptors other brands ignore. Your castor oil rituals should build trust with your body—not add to the hormone load it’s already carrying.
What Every Small Batch is Tested For:

Endocrine disruptors? Not on our watch.
Phthalates are sneaky chemicals found in plastic packaging and synthetic fragrances—and they’ve been linked to hormone disruption, especially in women. That’s why we rigorously screen every batch to make sure this oil is free of hormone-sabotaging phthalates.
We don’t test for just one—we screen for all 7 of the most common hormone-disrupting phthalates, including:
DBP, BBP, DEHP, DIDP, DINP, DnHP, and more.
What to look for in your lab results:
✓ “ND” (Not Detected) or “<1%” = Clean and safe
⚠️ Any detected level = Hormone load risk

No lead. No mercury. No compromises.
Low-quality oils can contain trace amounts of toxic metals like arsenic, lead, and mercury—especially when sourced or bottled without care. These metals build up in the body and can mess with everything from fertility to brain health.
What to look for in your lab results:
Each lab has a detection limit—if a metal isn’t found above that line, it’s marked “ND” (Not Detected).
In our test, that reads as “<0.2 ppm.”
What’s ppm?
It means parts per million—like 1 drop in a full bathtub when testing for a substance.
What’s safe?
According to the World Health Organization and U.S. Pharmacopeia, safe limits range from 1–10 ppm, depending on the metal.
What did we show?
Every heavy metal tested came back below 0.2 ppm.
That means we’re well under global safety limits—and proud of it.

Fresh oil = effective oil.
Peroxide value tells us how fresh your castor oil is—or whether it's started to break down. Oxidized oils lose potency and can irritate skin.
We test PV to make sure your oil is stable, safe, and ready to do its job.
What to look for in your lab results:
✓ Under 10 meq/kg = Fresh and stable (global safety limit)
✓ Ours: 1.139 meq/kg = Ultra-fresh, non-oxidized
⚠️ Over 10 meq/kg = May be rancid or irritating

This is where the magic lives.
Ricinoleic acid is castor oil’s star fatty acid—the reason it supports detox, digestion, lymph flow, and skin healing. But not all oils have enough of it.
We test every batch for potency, so you get results you can actually feel.
What to look for in your lab results:
✓ 85–92% = USP standard — therapeutic-grade potency
✓ 84–86% = Still high-performing for topical rituals and absorption
⚠️ Below 80% = Likely diluted or low-quality oil
Your oil tested at 87%—pure, potent, and made to perform.

Understanding Your Castor Oil Testing
Why test castor oil in the first place?
Your skin is your largest organ—and one of the most absorbent.
That’s why we test every batch for toxins, hormone disruptors, and signs of degradation.
Because this isn’t just about “clean beauty.”
It’s about your long-term health, hormonal safety, and trusting what your body absorbs.
What we test for:
- ✓ Ricinoleic Acid % = Potency + therapeutic performance
- ✓ Acid & Peroxide Value = Freshness and stability
- ✓ Phthalates & Heavy Metals = Hormone-safe assurance
- ✓ Fatty Acid & Saponification = Purity and authenticity
Why it matters:
Every oil touches your skin—and your skin talks to your hormones.
When you know what’s inside, you choose what your body absorbs.
And when you’re not sure? Dare to ask for the lab results. Your body deserves proof—not promises.
What’s ricinoleic acid—and what’s a good percentage?
This unique fatty acid is what gives castor oil its deep therapeutic and hormone-supportive benefits.
What to look for on your lab report:
- ✓ 85–92% = USP standard (therapeutic-grade potency)
- ✓ 84–86% = Still high-performing for topical rituals and absorption
- ⚠️ Below 80% = Diluted or poor-quality oil
The higher the percentage, the more effective your castor oil will be for things like belly bloating, hormone support, and inflammation relief.
What are phthalates—and why test for them?
Phthalates are hormone-disrupting chemicals often found in plastic packaging or poorly made oils.
Why it matters:
For women, they can mimic estrogen and interfere with your body’s delicate hormonal balance—especially when applied to the belly, breasts, or pelvis.
We don’t test for just one—we screen for all 7 of the most common hormone-disrupting phthalates, including:
DBP, BBP, DEHP, DIDP, DINP, DnHP, and more.
What to look for in your lab results:
- ✓ “ND” (Not Detected) or “<1%” = Clean and safe
- ⚠️ Any detected level = Hormone load risk
How do I know my oil is fresh and stable?
Peroxide Value (PV) tells you how much oxidation has occurred, aka how fresh your castor oil really is.
Oxidized oils can smell “nutty” or off, and may trigger skin reactions, headaches, or nausea.
What to look for:
- ✓ Under 10 meq/kg = Fresh and stable (global safety limit)
- ✓ Ours: 1.139 meq/kg = Ultra-fresh, non-oxidized
Why it matters:
Rancid oils can contribute to hormonal bloat, skin flare-ups, or feeling “off.”
You deserve stability you can trust.
Is your oil hexane-free and cold-pressed?
Yes. We never use hexane or chemical solvents. Our oil is cold-pressed—extracted without heat, pressure, or additives.
What to look for:
- ✓ Cold-pressed, hexane-free = Clean extraction, protects your skin
- ⚠️ Expeller-pressed or hexane-extracted = Often cheaper, but may involve high heat or chemical residue
Why it matters for women:
This oil is going on your belly, breasts, womb, and face—some of the most absorbent areas of your body.
Clean extraction helps protect your skin barrier, lymphatic flow, and hormone balance. No compromises.
Who chooses the castor oil you test and bottle?
We do. Every small batch is tested at the time of production—for purity, potency, and freshness.
We’re also proud that CastorOilReview.com independently selected our oil for testing alongside other leading brands—and the results spoke for themselves.
Ours ranked highest in purity.
Third-party proof. Real-world trust. Results you can actually feel.
