This page is for you—to show what goes into your bottle of Queen of the Thrones® Castor Oil, and why it meets the highest possible standards for purity and quality.

What You Can Expect from Our Castor Oil

We only use 100% pure, cold-pressed, hexane-free, USDA certified organic Castor Oil, with no fillers, preservatives, or fragrance.

Our sourcing and packaging standards are designed to help protect the oil’s integrity from the moment it’s bottled to the moment it touches your skin. You can count on:

  • Cold-pressed extraction (no heat, no chemicals)
  • Bottling in amber glass to reduce light exposure
  • Third-party and functional testing to check for contaminants and quality markers

Because if it’s not something we’d use on ourselves, it doesn’t go into your bottle.

Qué probamos

Esto es lo que hace que nuestro aceite de ricino se destaque como el mejor de su clase:

  • Porcentaje de ácido ricinoleico This is the signature fatty acid that gives Castor Oil its unique properties. For cosmetic-grade Castor Oil, a ricinoleic acid content of 80–90% is considered high quality.
    A diferencia de, USP (United States Pharmacopeia) oral-grade Castor Oil must meet stricter standards, typically ranging between 85-92%, to ensure consistency, purity, and suitability for its intended use. A higher ricinoleic acid percentage is often associated with a higher-quality oil, based on current manufacturing and purity benchmarks.
  • Detección de ftalatos — We make sure your oil is free from harmful plasticizers like DEHP, DBP, and others.
  • Valores de acidez, yodo, peróxido y saponificación — These are important markers that show oil freshness, quality, and stability.
  • Solventes residuales — Confirming no hidden hexane or chemical residues remain from extraction or processing.
  • Perfil de ácidos grasos — This ensures your oil perfectly matches pure Castor Oil’s unique fingerprint, with no adulteration or dilution.
  • Metales pesados ​​y contaminantes — Tested to remain well within safe, acceptable limits despite natural environmental exposure.
  • Pruebas microbianas y de estabilidad — Demonstrating your oil stays clean, shelf-stable, and effective over time without preservatives, thanks to its naturally low water activity.

The Latest Test Results

A Note About USP Standards vs. Topical Use Standards

Es posible que hayas oído hablar de USP (Farmacopea de los Estados Unidos) standards, which are created for Castor Oil used in pharmaceuticals or food products. These standards require a ricinoleic acid content of 85.0% -92.0% (see USP reference).

But here’s what’s important: topical-use Castor Oil has different quality considerations. Oils intended for cosmetic and self-care use often show slightly more natural variability in ricinoleic acid content. A range in the mid 80s to 90% is still consistent with high-quality topical Castor Oil, especially when supported by clean sourcing, organic certification, and gentle extraction methods like hexane-free cold pressing.

Queen of the Thrones® Castor Oil, with a tested ricinoleic acid level of ~ 84.8%, fits beautifully within these expectations—making it an ideal choice for your self-care and cosmetic rituals.
