  • Uses & Applications

    Pelargonic acid has a number of different uses in various industries and other applications. Some of the most common of these include:

    Cosmetics: Pelargonic acid is frequently used as an intermediate when synthesizing bio-lubricants and emollients in high-end cosmetics and personal care products. Our product helps improve spreading and absorption in hand and face creams, sunscreens and more. For cosmetics, it improves binding and pigment wetting, resulting in a product with superior feel and longer-lasting effects.

    Food and beverage: Pelargonic acid is an important raw material in certain food fragrances and bleaching agents. Because our product is derived entirely from sustainable vegetable sources, it is highly versatile and can be used in vegetarian- and vegan-friendly foods.

    Herbicides: Pelargonic acid is used to produce ammonium nonanoate, a key ingredient in many herbicides and plant protection products. Ammonium nonanoate, a natural full-spectrum weed suppressant, is water-soluble and biodegradable via microbial action, making it an excellent choice for safer, more natural control of invasive plants.

    Medicine: Nonanoic acid may be an effective way to treat seizures. Recent research has found that a ketogenic diet containing high levels of medium chain fatty acids such as nonanoic acid was more effective than Valproate in treating childhood epilepsy, and posed less risk of liver toxicity and related side effects.
