Aside asetiki ni aside yuzuye ya karuboni irimo atome ebyiri za karuboni kandi ni ikintu cy'ingenzi kivamo ogisijeni muri karuboni. Formula yayo ya molekile ni C₂H₄O₂, hamwe na formula y'imiterere ya CH₃COOH, kandi itsinda ryayo ry'imikorere ni itsinda rya karuboni. Nk'igice cy'ingenzi cya vinegere, aside asetiki y'ibara ry'umukara izwi kandi nka aside asetiki. Urugero, iboneka cyane cyane mu buryo bwa esters mu mbuto cyangwa amavuta y'imboga, mu gihe mu nyamaswa, mu bisohoka, no mu maraso, aside asetiki y'ibara ry'umukara ibaho nk'aside yigenga. Vinegere isanzwe irimo aside asetiki iri hagati ya 3% na 5%.

Amakuru aboneka ku myaka irenga 20 y'uburambe nk'umucuruzi wohereza hanze aside acetic glacial. Kanda hano kugira ngo ubone ibiciro.
