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.

Zinc Ricinoleate CAS 13040-19-2

Zinc Ricinoleate (CAS 13040-19-2) is a specialized metallic fatty acid salt utilized as a highly active odor-absorbing agent in household cleaners and industrial deodorant formulations. Chemically identified as Zinc diricinoleate or the Zinc salt of ricinoleic acid, this waxy solid functions by chemically fixing low molecular weight nucleophilic compounds, such as isovaleric acid and amines, rather than merely masking them with fragrance. As a stable Zinc carboxylate complex, it is integrated into detergents, waste treatment systems, and air fresheners to neutralize malodors effectively. We ensure bulk supply capabilities for this material, providing access to competitive factory pricing and customized specifications to meet specific solubility or activity requirements. Full technical documentation, including MSDS, TDS, COA, is available to support compliance and safety protocols.

Product Description

Zinc Ricinoleate is the zinc salt of ricinoleic acid, a major fatty acid found in castor oil. Unlike traditional antiperspirants that block pores or deodorants that mask smells with heavy perfumes, Zinc Ricinoleate works through a unique “cage” mechanism. It effectively chelates (binds) nucleophilic odor-causing molecules—specifically those containing Nitrogen (like ammonia and amines) and Sulfur (like mercaptans and hydrogen sulfide).

Once bound to the Zinc Ricinoleate, these odor molecules cannot be released back into the atmosphere, even upon drying. It is biologically degradable, skin-friendly, and suitable for sensitive skin formulations. It is widely compatible with non-ionic and anionic surfactant systems.

Applications

Personal Care & Cosmetics:
- Deodorants: Primary active ingredient in stick, roll-on, and cream natural deodorants.
- Foot Creams: Neutralizes foot odors effectively.
- Body Washes & Soaps: Adds odor-neutralizing properties to cleansing products.
Household Products:
- Air Fresheners: Used in solid or gel air fresheners to eliminate kitchen or pet odors.
- Fabric Sprays: Removes odors from upholstery, curtains, and carpets.
Industrial Uses:
- Waste Treatment: Used in sewage and waste treatment facilities to control strong odors (H2S, Ammonia).
- Plastics & Rubber: Acts as a stabilizer and odor scavenger during processing.

Storage Conditions

Environment: Store in a cool, dry, and well-ventilated area away from direct sunlight.
Temperature: Keep temperature below 35°C to prevent caking or melting (as the melting point is relatively low).
Sealing: Keep containers tightly closed when not in use to prevent moisture absorption and contamination.
Shelf Life: typically 24 months under proper storage conditions.

Safety Precautions

Handling: Wear appropriate personal protective equipment (PPE), including safety glasses, gloves, and a dust mask if handling powder form to avoid inhalation.
Skin Contact: Non-irritating in cosmetic formulations, but wash with soap and water after handling raw concentrated material.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do.
Fire Safety: Combustible solid. In case of fire, use dry chemical powder, carbon dioxide, or foam.
