Preparation of Eco-Friendly Coffee Scrub from Spent Coffee Grounds

The increasing demand for natural products has driven significant interest in utilizing waste materials as primary ingredients in the cosmetic industry. With the rising global consumption of coffee, the accumulation of spent coffee grounds has become a growing environmental concern. This study addresses this issue by preparing a body scrub using spent coffee grounds and evaluating its spreadability, odor, color, and pH to determine its suitability for skincare applications. Three formulations were developed using varying proportions of sugar, baking soda, and spent coffee grounds. The results demonstrate that ingredient ratios significantly impact the scrub’s physical characteristics and overall user experience. Notably, the sample with reduced sugar content exhibited a smoother texture, making it more suitable for a wider audience, including individuals with sensitive skin. Formulation 2 emerged as the most effective formulation, achieving the highest spreadability (4.53 cm), a balanced pH of 5, and a smooth, slightly oily texture that left the skin feeling soft and moisturized—ideal for sensitive skin. In contrast, Formulation 1, with its gritty texture, proved too abrasive, while Formulation 3, which contained baking soda, had a less acidic pH (6) and a powdery texture, providing moderate exfoliation. These findings highlight the potential of spent coffee grounds as a sustainable, eco-friendly alternative in skincare formulations, contributing to the advancement of environmentally conscious cosmetic products while offering a practical solution for coffee waste management.
