The Packaging Science Center (PSC) teams initiate and pilot scientific and technical programs in the fields of Materials, Transformation & Recycling, Dispensers & Applicators to respond to L'Oréal’s challenges regarding sustainability, consumer experience and product performance.

Here’s an overview of activities held by the three domains from PSC :  

• Materials Science oversees researching, developing, characterizing, and validating new polymer, cellulosic and inorganic materials that can be activated by the Group's packaging entities to launch the next generations of cosmetic products. The team takes a stand in guaranteeing the performance and safety of our products.
• Transformation & Recycling Science aims at exploring, experimenting & creating the processes that will allow new finished packaging components to be developed, according to various material challenges. The target is also to ensure the sustainable end of life for every future product on the market.
• Dispensers & Applicators Science activities follow the scientific triad exploration/analysis/experimentation. The goal is to first investigate the problem to be solved regarding the targeted packaging component and outline a holistic understanding of it, to then characterize the parameters that may influence its performance, and finally to design and test new technological solutions aiming to provide innovative packaging components for L’Oréal.

1/  Research & innovation apprenticeship on aerosol products with a focus on spray performance & sustainability aspects, Dispensers & Applicators Domain

sous-Bois, Ile-de-France

• As part of the L'Oréal For The Future program, L'Oréal wants to reduce the environmental impact of 100% of its products. One challenge in the aerosol category is to replace liquefied gases with compressed gases, which requires work on packaging in order to achieve a product performance equivalent to current aerosols. The second challenge is to reduce the impact of packaging by making it lighter, recyclable and using recycled materials.
• Strengthen the scientific knowledge on the spraying of formulas,
• Potentialize the first technological solutions for new categories of formulas (dry shampoos, hair dyes, sun care products, etc.)
• Identify and characterize new solutions in partnership with our suppliers,
• Set up a guide that will summarize all the knowledge and good practices,
• Contribute to the integration of aerosol data analysis tools in order to be more efficient in the search for solutions
• You will collaborate internally with other teams of the L'Oréal group, formulation research, packaging innovation, the sustainability team, materials research, etc. Externally, you will work with suppliers, external laboratories, universities/scientists who are experts in their field, start-ups, ...
• This apprenticeship will allow you to work in a very diversified environment, composed of coworking spaces, laboratories, and state-of-the-art equipment such as cobots and tomography. You may be required to travel to Saint-Ouen and to suppliers in Europe. Part of the mission will be spent in the laboratory to test and characterize the product solutions worked on.

• Develop your scientific approach and lead scientific projects
• Analyse, model, synthesise and present data
• Acquire global packaging knowledge and particularly on the aerosol category
• Work collaboratively with internal and external partner

• Elastomers are present in many packaging applications: seals, pipette nipples, make-up applicators, mascaras, etc. In order to respond to environmental issues, we are opening a project to replace these elastomers with more sustainable and consumer-safe solutions. Your mission will consist of:
• Taking stock of the group's packaging using elastomers
• List the characteristics of these elastomers, their mechanical and physico-chemical properties, their uses, and understand how they are manufactured
• Monitor elastomers in order to identify new solutions or existing solutions not deployed at L'Oréal
• Create the extended ecosystem (tier 1, 2 and 3 suppliers, start-ups, universities or expert researchers, players from other sectors, external laboratories, etc.).
• Define the roadmap and initiate the first projects.
• Test these new materials applied to cosmetic packaging and characterize them
• You will collaborate internally with the other PSC teams (materials experts and experts in the transformation of materials located in France but also in China and the US), but also with the packaging teams in charge of make-up, the team in charge of sustainability or the people in charge of innovation projects. Externally, you will work with suppliers, external laboratories, scientists and universities.
• This apprenticeship will allow you to work in a very diversified environment, composed of coworking spaces, laboratories, and state-of-the-art equipment such as cobots and tomography. You may be required to travel to Saint-Ouen and to suppliers in Europe. Part of the mission will be spent in the laboratory to test and characterize the product solutions worked on.

• Develop your knowledge of elastomers applied to cosmetic packaging
• Increase your competence in the scientific approach and manage scientific projects
• Acquire global knowledge of packaging & the cosmetic industry through the L'Oréal ecosystem
• Contribute to the life of the team and work in collaboration, including with other departments and external partners
