Development and assessment of stable formulations containing two herbal antimicrobials: Allium sativum L. and Eruca sativa miller seed oils.

Context: Garlic oil and Eruca oil have been reported to have excellent antimicrobial activity. However, the exact knowledge of their required hydrophilic-lipophilic balance (rHLB) values to facilitate their emulsification are still not reported in the literature.

Objective: The objective of this study is to determine rHLB values of Garlic and Eruca oils to formulate an elegant stable cream formulation enriched with both oils.
