Zinc Ricinoleate is a highly effective odor-absorbing ingredient supplied in wax-like pellet form, widely used as a key component in deodorant formulations. As the zinc salt of ricinoleic acid derived from castor oil, it works by chemically trapping and absorbing odor molecules formed during the bacterial decomposition of perspiration, rather than masking them with fragrance.
This makes it a reliable choice for deodorant systems that need real performance without interfering with the skin. Zinc Ricinoleate does not inhibit perspiration and has no bactericidal or fungicidal activity, allowing the skin’s natural flora to remain undisturbed.
With a melting point of ~71°C (160°F), it easily incorporates into the oil phase of formulations and blends smoothly with oils and waxes. Its high biodegradability (~99%) and naturally derived origin make it suitable for modern, clean, and performance-driven formulations.
Key Features & Benefits of Zinc Ricinoleate
Odor Absorption: Chemically binds and traps odor molecules at the source
Non-Antiperspirant: Does not block sweat glands or inhibit transpiration
Skin-Friendly: Does not disrupt the natural microbiome of the skin
Naturally Derived: Based on castor oil (ricinoleic acid) and zinc
Biodegradable: Approximately 99% biodegradable
Oil Compatibility: Easily melts and integrates into oils and waxes
