Journal of Chemistry Sciences and Education (JCSE) is a journal of chemical science and education published by Pubsains under the management of PT Pubsains Nur Cendekia. This journal provides readers with current developments in chemical science and education through the publication of articles and research reports. Each author is responsible for the content of their published articles. JCSE contains papers/articles on ideas and research in the field of chemistry education and learning, both theoretically and empirically reviewed. The journal covers critical thinking and assessment skills in chemical science and education: a) Organic chemistry, inorganic chemistry, analytical chemistry, physical chemistry, environmental chemistry, and medicinal chemistry; b) Innovations in chemistry learning, curriculum development, and educational psychology in chemistry. All articles are peer-reviewed by experts before being accepted for publication. Journal of Chemistry Sciences and Education (JCSE) is published twice a year, in May and October. The journal is open to authors worldwide, regardless of nationality.

Abstract

Glycolic acid is a widely used peeling agent in skincare cosmetics that is effective in treating hyperpigmentation, wrinkles, and acne scars. However, due to its potential to cause irritation and erythema, the concentration of this substance in cosmetic products must be strictly controlled. This study aimed to develop an analytical method and to establish a reference value for glycolic acid in order to enhance laboratory testing capabilities for the regulatory surveillance of cosmetic products in the community. Raw material characterization was carried out using infrared spectrophotometry and High-Performance Liquid Chromatography (HPLC). Purity testing was performed using Differential Scanning Calorimetry (DSC) and HPLC, while water content was determined by coulometric analysis. Homogeneity testing and assignment of the content (assigned value) were conducted using an HPLC–PDA system equipped with an autosampler and a C18 column (250 × 4.6 mm i.d., 5 µm). The mobile phase consisted of 15% methanol (pH 2 adjusted with 85% orthophosphoric acid). The results showed that the raw material purity determined by DSC was 98.06% with a melting point of 74.15 °C, while HPLC purity testing detected a total impurity level of 0.40%. The water content of the raw material was recorded at 0.62%. Statistical analysis confirmed that the material was homogeneous, as indicated by an F calculated value lower than the F table value (1.97 < 3.02). Using this method, the assigned value of glycolic acid content was determined to be 98.98% with an associated uncertainty (U) of 1.54%. All validation parameters of the developed analytical method met the acceptance criteria, demonstrating that the HPLC–PDA method is accurate and valid for the determination of glycolic acid content. Based on the purity profile, homogeneity, and assigned value obtained, this raw material is legitimate and suitable for use as a glycolic acid reference standard in cosmetic testing.

Abstract

This study investigates the extraction, characterization, and aromatic classification of ginger (Zingiber officinale) using enfleurage and maceration techniques. Enfleurage was employed as a mild, non-thermal method to preserve thermolabile volatile compounds, while ethanolic maceration was used to obtain aromatic tincture. The resulting extracts were evaluated through organoleptic analysis, physicochemical characterization (pH and density), and aromatic note classification based on volatility and persistence. The results indicate that petrolatum-based enfleurage successfully captured volatile aromatic fractions with dominant top-note characteristics, whereas maceration produced a tincture with stable physicochemical properties and strong initial aroma intensity. These findings demonstrate that method selection significantly influences aroma profile, stability, and applicability in cosmetic and perfumery formulations.
