What is Zinc Ricinoleate CAS 13040-19-2?

Zinc Ricinoleate CAS 13040-19-2 is the zinc salt of ricinoleic acid, a fatty acid obtained from castor oil. It is a high-purity odor-absorbing active supplied as white to pale yellow granules, powder or waxy solid.

How does Zinc Ricinoleate neutralize odor?

It traps low-molecular-weight nucleophilic odor compounds such as amines, ammonia, mercaptans and hydrogen sulfide. Once bound in the zinc ricinoleate structure, the odor molecules are not released even after drying.

Is Zinc Ricinoleate an antiperspirant or antimicrobial?

No. It is a deodorant active that fixes odor molecules already produced. It does not block sweat glands and is not considered bactericidal or fungicidal, so it does not interfere with the natural skin flora.

What applications are most common for Zinc Ricinoleate?

It is used in stick, roll-on and cream deodorants, body washes, soaps and foot-care products. It also appears in air fresheners, fabric sprays, household cleaners and industrial odor-control formulations.

How is Zinc Ricinoleate incorporated into cosmetic formulations?

Because it is insoluble in water but soluble in oils and organic solvents, it is usually dissolved or dispersed in the oil phase. It is compatible with non-ionic and anionic surfactant systems, making it suitable for emulsions and surfactant-based products.

What purity and zinc content does the cosmetic grade provide?

The standard cosmetic grade has an assay of at least 98.0% and a zinc content of 10.5-12.5%. Its melting point is 70-85 C and loss on drying is no more than 1.0%.

How should Zinc Ricinoleate be stored?

Store it in a cool, dry, well-ventilated area below 35 C with containers tightly closed. Avoid direct sunlight and heat to prevent caking or melting; the typical shelf life is about 24 months under proper storage.

Product Description

Zinc Ricinoleate, CAS 13040-19-2, is the zinc salt of ricinoleic acid, the major fatty acid of castor oil; the EC/EINECS number is 235-907-4.

Synonyms: zinc diricinoleate; ricinoleic acid zinc salt; zinc(II) ricinoleate; zinc carboxylate.

CAS: 13040-19-2.

Molecular formula: C₃₆H₆₆O₆Zn.

Molecular weight: 663.86 g/mol.

EC number: 235-907-4.

It is a white to pale-yellow granule, powder or waxy solid with a mild fatty odor.

It typically has an assay of at least 98.0% and a zinc content of about 10.5–12.5%.

It works by a chelating cage mechanism, binding odor-causing nitrogen and sulfur molecules such as ammonia, amines, mercaptans and hydrogen sulfide.

It is used as the primary active in natural deodorants, foot creams, body washes and soaps.

It is used in household air fresheners and fabric sprays to eliminate kitchen, pet and textile odors.

It is used in sewage and waste treatment to control strong odors, and in plastics and rubber as a stabilizer and odor scavenger.

It is biodegradable, skin-friendly, suitable for sensitive-skin formulations and compatible with non-ionic and anionic surfactant systems.

Confirm assay, zinc content, appearance, melting point, loss on drying, heavy metals, arsenic, pH and solubility.

Store in a cool, dry, ventilated area away from direct sunlight, keeping temperature below 35 °C.

Keep containers tightly closed when not in use to prevent moisture absorption and contamination.

Confirm packaging with the requested quantity and destination requirements.
