OriginMethyl pelargonate is a synthetic ester derived from pelargonic acid (a nine-carbon fatty acid) and methanol. It is produced through esterification, combining pelargonic acid with methanol using acid catalysts.
Methyl nonanoate is a fatty acid methyl ester obtained from the formal condensation of methanol and nonanoic acid; a colourless liquid with a fruity odour, used in perfumes and flavours, and for medical research. It has a role as an antinematodal drug, an antifungal agent, a fragrance, an epitope and a plant metabolite. It is functionally related to a methanol and a nonanoic acid.

Functions
Perfuming
Added for scent. Can be natural or synthetic. Common irritant and allergen — one of the top reasons people react to products.
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
