L2 Métiers de la Chimie Internship
Second-Year Chemistry Internship (L2 Métiers de la Chimie)
April 7 – August 1, 2025
Sales, Research & Development
REDA Chemicals & OPTIChem, Dubai, United Arab Emirates
REDA Chemicals is an international group specializing in the distribution of chemical raw materials across the food, cosmetics, industrial, and pharmaceutical sectors. Optichem, a subsidiary of the group, focuses on innovation, formulation, and the development of tailored technical solutions. Together, these entities combine scientific expertise, commercial insight, and technical support, serving as a bridge between global suppliers and local markets.
My project at REDA Chemicals & Optichem
During my internship, I took part in several projects combining research and development with
a business and industrial approach.
One of my main projects focused on the development of a colorless cobalt-based resin system
intended for button manufacturing. The objective was to achieve a gel time of around 5 minutes
while maintaining a stable, high-performance, and non-colored resin. This work involved
formulation trials, catalyst adjustments, and evaluation of the final material properties.
At the same time, I worked on a separate project aimed at reducing the viscosity of zirconium-
based formulations to improve their processability and compatibility with industrial applications.
This project allowed me to further develop my skills in formulation, physicochemical
characterization, and optimization of technical parameters.
Beyond R&D, I also contributed to business development activities, including analyzing client needs, understanding the industrial applications of products, and promoting the solutions developed.

At the end of this internship, I was awarded a certificate in recognition of my commitment, the quality of my work, and the skills I developed during this professional experience.
Technical Skills Gained During the Internship
Formulation & R&D
Formulation and optimization of industrial resins according to precise technical criteria (gel time, color, stability).
Conducting comparative experimental trials with control samples.
Fine adjustment of additive concentrations (catalysts, solvents, preservatives) based on observed results.
Analysis of the impact of chemical interactions on polymerization, viscosity, and the final appearance of the product.
Implementation of an iterative experimental approach (test → analysis → optimization).
Identification of causes of non-reproducibility despite a constant protocol.
Quality Control & Analysis
Application of standardized industrial protocols in formulation and quality control.
Measurement and interpretation of key physicochemical parameters:
refractive index
