Isononyl isononanoate

Isononyl isononanoate (CAS 59219-71-5) is a synthetic ester used as an emollient, solvent, and plasticizer in personal care and pharmaceutical formulations. Produced from isononanol and isononanoic acid, it delivers a dry, non-greasy skin feel.

This unique texture distinguishes it from heavier esters in cosmetic applications. In skin care and color cosmetics, it functions as an emollient and spreading agent in creams, lotions, foundations, and lip products.

The ingredient improves texture and application without leaving a heavy residue. Sunscreen formulators use it as a solvent carrier for UV filters, aiding dispersion and enhancing film formation on the skin surface.

In pharmaceutical topical preparations, it acts as a plasticizer and penetration-enhancing carrier for active ingredients in creams and ointments. This ensures effective delivery of the medicinal components.

Hair care applications include its use in conditioning treatments and styling products, where it improves slip and manageability. It provides a lightweight finish that does not weigh down the hair fibers.

The product is supplied as a clear, low-viscosity liquid in drum and IBC quantities. Cosmetic-grade material is the standard commercial offering, with purity specifications typically meeting requirements for personal care.

The material is also suitable for topical pharmaceutical use. Technical-grade material is available for industrial plasticizer applications, ensuring versatility across different manufacturing sectors and product types.
