Zinc ricinoleate

Zinc ricinoleate (CAS 13040-19-2 ), also known as zinc diricinoleate, is the zinc salt of ricinoleic acid derived from castor oil. It functions as a molecular odor absorber, trapping and neutralizing malodorous compounds rather than masking them with fragrance.

This mechanism makes it a sought-after active ingredient wherever durable, non-perfumed odor control is required. In personal care, it is the primary active in deodorant sticks, roll-ons, and sprays formulated as fragrance-free or clean products.

The compound binds odor molecules directly on the skin for effective results. Textile and leather processors apply it in finishing treatments to impart lasting odor control to sportswear, footwear linings, and technical fabrics.

In coatings and sealants, it functions as a surface modifier and dispersing agent, improving pigment wetting and stabilizing formulations. Adhesive and elastomer manufacturers also use it as a processing aid to influence surface tack.

The material is highly valued for its compatibility with fatty acid-based systems. Zinc ricinoleate is supplied as a white to off-white powder or as a waxy solid, depending on the specific grade and processing requirements.

Standard commercial grades are available for cosmetic and industrial applications. Cosmetic-grade material typically meets purity requirements aligned with REACH and ISO 16128 natural origin criteria for global compliance.

Bulk supply is common in 25 kg bags or fiber drums to suit large-scale manufacturing. This versatile chemical remains a staple for formulators seeking natural, high-performance solutions for odor neutralization and surface modification.
