ABSTRACT
Purpose:
Sensory perception and performance are important aspects for the successful development of cosmetic in the market. In this study, we aimed to prepare semi-permanent eyebrow formulations and perform a sensory evaluation of the same.
Method:
We prepared semi-permanent eyebrow cosmetic (SEC) formulations of different pHs (pH 3.0, 4.0, 5.0 and 6.0) and evaluated the sensory attribute on a 5-point Likert scale. The test panel comprised women aged 20-39 years who were SEC users and were recruited from an organization via invitation.
Results:
In sensory evaluation, no difference was noted among samples regarding their spreadability and usability. This is attributable to the fact that the tested samples were prepared in the same form as the liquid type of SECs. The SEC (pH 3.0) and SEC (pH 4.0) showed a high satisfaction level for the color strength and tenacity. These results are likely to be related to the pH regulator components (i.e., citric acid and sodium citrate).
Conclusions:
The following was the prominent finding of the sensory evaluation: formulations with a low pH (<4.0) are beneficial for maintaining the coloration (i.e., color strength and tenacity) in SECs.
Key words: Color cosmetics, Semi-permanent eyebrow, pH, Formulation, Sensory evaluation
