Development of a Self‐Adhesive Oleogel Formulation Designed for the Slow Release of Semiochemicals

Abstract Oleogels have been widely studied as delivery matrices for lipophilic compounds. Despite their potential, oleogels are underexplored the formulation and release of semiochemicals insect behavior manipulation strategies. An ethylcellulose‐candelilla wax‐oleogel a suitable carrier slow volatile semiochemicals, employing sesquiterpene β ‐caryophyllene model substance is presented. A current drawback ethylcellulose high temperature needed during oleogel preparation procedure, leading to excessive volatilization active Reducing gelling from 104.8 66.9 °C and, thus, addition by softener octyldodecanol results in 95.28% entrapment efficiency. Experimental demonstrate modifiability tailoring matrix crystalline state due candelilla wax addition. Furthermore, method established analyzing self‐adhesive properties gel on plant leaves. In addition, gel's employed apple leaves synergistically affected oil leakage stiffness. Olfactometer experiments showed that able enhance attractiveness aphid‐infested plants parasitic wasps. The present study provides novel matrix‐type semiochemical based non‐toxic, biobased biodegradable materials will contribute establishment systems semiochemicals.
