Hoʻohana nui ʻia ka waikawa Stearic i nā mea hoʻonani, nā plasticizers plastic, nā mea hoʻokuʻu, nā mea hoʻopaʻa, nā surfactants, nā mea hoʻolalelale vulcanization rubber, nā mea pale wai, nā mea hoʻopili, nā kopa metala, ka flotation mineral metala, nā mea palupalu, nā lāʻau lapaʻau, a me nā kemika organik ʻē aʻe. Hiki ke hoʻohana ʻia ka waikawa Stearic ma ke ʻano he mea hoʻoheheʻe no nā pigments hiki ke hoʻoheheʻe ʻia i ka ʻaila, kahi lubricant no nā crayons, kahi mea hoʻopili no ka pepa wax, a me kahi emulsifier no nā glycerides waikawa stearic.
Hoʻopili pinepine ʻia i loko o 25kg / pahu, a hiki ke hana ʻia kahi pūʻolo i hoʻopilikino ʻia.
