Is aigéad sailleach sáithithe é an t-aigéad stéarach le slabhra 18-carbóin. Is é an t-ainm molta ag AIGCFan t-aigéad ochtaideacánóch. Is solad céiriúil é agus is é C17H35COOH a fhoirmle cheimiceach. Tagann a ainm ón bhfocal Gréigise στέαρ "stéar ", a chiallaíonn 'geir'. Tugtar stéaráití ar shalainn agus eistir an aigéid stéaraigh. Mar eistear, is é an t-aigéad stéarach ceann de na haigéid shailleacha sháithithe is coitianta a fhaightear sa nádúr, i ndiaidh an aigéid phailmítigh. Tugtar stéaraín ar an tríghlicríd a dhíorthaítear ó thrí mhóilín den aigéad stéarach.

Baintear feidhm as i ndéanamh gallúnaí is coinnle.
