Stactic acid, (ọkwa ụlọ ọrụ) stareic acid bụ otu n'ime ọtụtụ abụba na-enwekarị mmanụ na abụba. A na-egosi ya na abụba anụmanụ, mmanụ na ụdị ihe oriri mmanụ mmanụ dị ka ọma, ụdị nke glycerides. Mmanụ ndị a, mgbe hydrolysis, na-emepụta stacid acid.
Stearic acid bụ acid acid na-adịkarị na okike ma nwee akụrụngwa kemịkalụ nke croxylic acid.
