What is Zinc Diricinoleate？

Zinc Diricinoleate is a zinc salt of ricinoleic acid derived from castor oil. It is widely used as an odor-absorbing agent in personal care products and deodorants. The compound works by chemically binding odor-causing molecules and neutralizing them. Zinc Diricinoleate is considered a green ingredient due to its renewable plant-based origin and its low environmental impact. In addition to its deodorizing properties, it is also used in industrial formulations such as adhesives, rubber, plastics, and coatings due to its dispersing and stabilizing characteristics.

Application

Zinc Diricinoleate used in deodorants as an odor-neutralizing agent
Zinc Diricinoleate acts as a stabilizer and dispersant in polymer and plastic formulations
Zinc Diricinoleate can be applied in rubber processing to enhance performance and reduce odor
Zinc Diricinoleate utilized in coatings and adhesives for its compatibility and hydrophobic nature
Serves as a biodegradable alternative to synthetic odor absorbers in cosmetics

Deodorizing:

Zinc diricinoleate is effective at capturing and neutralizing malodors by binding to sulfur and nitrogen-containing compounds.

Personal care:

It is a common ingredient in natural deodorants because it traps odor-causing molecules without blocking the natural sweating process. It is also used in other cosmetics like makeup, lip balm, and hair-loss treatments.

Industrial applications:

Plastics and rubber:

Used as a stabilizer and for its gelling properties.

Paints and coatings:

Acts as an opacifying agent.

Other uses:

Incorporated into products for its gelling, emulsifying, and waterproofing properties.

How it works

The zinc atom in the molecule selectively binds to the sulfur and nitrogen parts of odor molecules.

The ricinoleate chains then physically trap and encapsulate these molecules, preventing them from being released into the air and being smelled.

Safety profile

Zinc Diricinoleate is non-toxic and considered safe for use in personal care applications. It is not classified as a skin sensitizer or irritant under normal usage conditions. Being derived from renewable castor oil, it is environmentally friendly and biodegradable. It is also free from heavy metals and common allergens, though patch testing is still recommended for sensitive users.

Storage requirements

Store in a cool, dry place
Keep containers tightly sealed and away from moisture
Avoid exposure to strong acids or bases and direct sunlight
