Pre-Formulation Study on The Preparation of Skin Cosmetics

Abstract

Cosmetics have been a trend necessary for all people. The increasing need of the community in the use of cosmetics becomes the basis of the formulation of this article. Pre-formulation study for cosmetics is important to ensure that the final preparation of the cosmetics is safe to use and has maintained quality. A pre-formulation study for cosmetics is a study of physicochemical characteristics associated with the substances used in the formulation of cosmetics preparation to produce a quality cosmetic product. The pre-formulation study described here includes evaluation of sensitivity and irritability, organoleptic, formulation compatibility, thermal effect, partition coefficient, stability, particle size, wettability, hygroscopicity, type of preparation, and pH. This review article is compiled by searching for literature associated with the topic studied. Taken together, this review suggests that the pre-formulation study described recommended to be performed during the information searching step related to the physicochemical properties of ingredients used for cosmetic preparations. All of the topic studied is beneficial to determine the quality of the ingredients within the preparation before formulation, therefore, the production of cosmetic preparation can be more effective because it directs the choice of ingredients and optimum ingredient composition.

The Potential of Lactiplantibacillus plantarum ATCC 14917 in the Development of Alginate-Based Gel Formulations with Anti–Staphylococcus aureus Properties

“…It was observed that the bacteria incorporated in the gel stored at 5 • C remained viable, and the gel was stable throughout the assay. The same happened in other studies, where the formulations showed better viability and stability when stored at 5 • C and 4 • C [54,55].…”

Formulation of Botanical Shampoo Infused with Standardised Mangosteen Peel Extract for Healthy Hair and Scalp

“…To maintain the properties and final product of the hair shampoo, the compatibility of the active ingredients and excipients was evaluated. This is to ensure that the final product produced meets the aesthetic function, and maintains the physical and chemical properties within the preparation [22]. The physical compatibility study is essential to determine any incompatibility between the extract and excipients in the final formulation.…”
