Abstract Protecting the environment is an international issue that
depends a lot on the involvement of each of us through actions to collect
and recycle different used products. The purpose of this paper is to show
that used cooking oils should be collected to be transformed into ecological
laundry care products: soaps. The laundry soaps prepared by us were obtained
through hot saponification processes, using the mixture of palm and coconut
oils, unused and used/waste, in all 4 possible combinations. The
characterization of the vegetable oils was carried out by determining the
saponification value (SAP) and the iodine number (IN). The obtained soaps
were characterized physically and chemically by determining pH, foam, color,
density, cleaning/washing capacity inclusive the SAP, IN, INS (Iodine Number
Saponification) values for oils mixture from soaps. The tested ecological
soaps are excellent products for washing clothes because each has a low
foaming and an excellent cleaning capacity. KeKeywords: laundry soaps,
