Description
Nonacosanoic acid (CAS 4250-38-8, EC 224-210-9) is a saturated long-chain fatty acid with the molecular formula C29H58O2, also referred to as enneacosanoic acid or n-nonacosanoic acid. It carries no assigned E-code and belongs to the oils, fats, and waxes chemical category.
In personal care formulations, nonacosanoic acid functions as an emulsifier by reducing interfacial tension between oil and water phases, supporting stable cream and lotion systems. In food and nutrition applications, it contributes humectant activity, helping retain moisture within processed food matrices by interacting with water at the molecular level.
Nonacosanoic acid is supplied in powder to crystal form and falls under HS code 2915.90.1800 for customs classification within the EU. It is subject to REACH registration requirements for quantities above one tonne per year. Procurement teams should confirm grade specifications and packaging formats directly with the supplier.
