Sensory perception and performance are important aspects for the successful development of cosmetics in the market. This study was to prepare the hypo-allergenic foam cleansers depending on various pH levels and perform a sensory evaluation. We prepared the foam cleanser formulations of different pHs; control(pH 9.0), sample A(pH 7.0), sample B(pH 9.0) and evaluated the sensory attribute on 5 points Likert scale. The prepared foam cleansers were used to test the reliability of the 30 panels on five questions: bubble volume, hydration, detergency, irritation, applicability sense. The result of the sensory evaluation showed that no difference was noted among samples regarding their bubble volume and applicability sense. This is attributable to the fact that the tested samples were prepared in the same formulation as the foam type. Interestingly, sample B showed the highest satisfaction level for the hydration, detergency, and irritation, showing significant differences among groups. The reason for this sensory evaluation results is related to the pH level of formulation. This experiments confirmed the positive expectation for the development of hypo-allergic foam cleanser (pH 5.0). The following was the prominent finding of the sensory evaluation: foam cleanser formulation with a 5.0 pH are beneficial for high satisfaction.
