Formulation and Analysis of a Cosmetic Product
Chitine Glow – Sustainable Cosmetic Innovation
Chitine Glow is an innovative cosmetic project focused on transforming insect-derived waste into a high-value, sustainable anti-aging active ingredient. The project explores the use of chitin and its derivative, chitosan, as a multifunctional cosmetic ingredient, combining scientific performance with environmental responsibility.
Developed within an academic and research-driven framework, this project aims to address the growing demand for green beauty solutions while maintaining high standards of safety, efficacy, and regulatory compliance.
My Role & Project Outcomes
In the Chitine Glow project, I contributed to both laboratory and research activities, supporting cosmetic formulation development and the transformation of chitin into chitosan for cosmetic applications. I participated in experimental work, basic analytical tasks, and collaborated with team members across different project areas.
The project led to the development of a sustainable anti-aging cosmetic concept, while strengthening my practical skills in cosmetic science, teamwork, and applied research.
Design and Fabrication of a Nitrite Colorimeter
Project Overview
This academic project focused on the design and construction of a low-cost colorimeter to measure nitrite concentrations in aquarium water. Nitrites are toxic intermediates in the nitrogen cycle, and their monitoring is essential to ensure a healthy aquatic environment.
The objective of this project was to apply analytical chemistry principles, instrumentation, and basic electronics to develop a functional and reliable measurement device.
My Contributions and Outcomes
Within the project team, I was primarily responsible for the preparation of standard and sample solutions, as well as participating in experimental measurements and data interpretation. The analytical method was based on the Griess reaction, producing a pink coloration proportional to nitrite concentration, with measurements performed at an optimal wavelength of 543 nm.
The prototype combined an optical system (LED and phototransistor) with an Arduino microcontroller to collect, analyze, and display absorbance data. The results obtained using the homemade colorimeter were compared with spectrophotometric measurements, demonstrating that the device was capable of detecting low nitrite concentrations, although close to its sensitivity limit.
This project strengthened my skills in analytical chemistry, laboratory experimentation, data analysis, and scientific teamwork, while also introducing me to instrument design and basic electronics.
