Nanoparticles in cosmetics: Eurofins C&PC’s comprehensive and integrated testing solution

As the use of nanomaterials continues to rise in cosmetic formulations, regulatory expectations and scientific scrutiny are becoming increasingly stringent. The SCCS and ISO guidelines have outlined precise requirements for the characterisation and safety assessment of nanoparticles, placing new demands on manufacturers and R&D teams.

At Eurofins C&PC, we offer a comprehensive service portfolio tailored to ensure regulatory compliance and product safety when dealing with nanomaterials in cosmetic products. Our approach begins with formula stability and proceeds through a tiered evaluation process depending on the need for sample preparation (distribution, dispersion, etc.) in accordance with SCCS guidelines.

Depending on the formulation, we perform a sample preparation phase followed by in vitro safety testing under GLP: cytotoxicity, phototoxicity, irritation assays (eye, skin, vaginal, oral), sensitization, genotoxicity, chromosomal aberration, and more.

Moreover, when analytical characterisation is required, we leverage our accredited laboratories (ISO 17025, ISO 9001) to assess nanoparticles at an advanced level. This includes chemical composition, surface interactions and structure, agglomeration state, diameter, and physico-chemical properties via robust methodologies, and equipment (ICP-MS, SEM, TEM, etc.).

With deep expertise and cutting-edge infrastructure, Eurofins C&PC supports your innovation while ensuring full regulatory alignment, providing clarity in the complex field of nanomaterial testing.

Testing tomorrow’s make-up: Between brave creativity and scientific rigour

As we enter the second half of 2025, make-up trends are merging aesthetic innovation with ethical and technological advancement. The spotlight is on skin that appears naturally smooth and healthy, paired with bold creative statements – think metallic shines, futuristic glosses, vivid pigments, and creative placement of blush, liner, and lipstick. This visual creativity is now expected to coexist with strong eco-conscious and high-performance claims.

At Eurofins C&PC, we empower cosmetic brands to meet these dual demands through:

Robust analytical testing:

• Allergen screening
• Heavy metals detection
• Microplastics analysis
• PFAS analysis
• UV filters and preservative quantification
• Identification of nourishing and functional ingredients
• Titanium dioxide, phthalates, formaldehyde, and fluoride testing
• And more.

And multicentric clinical studies:

• Evaluation of skin radiance and oxygenation
• Hydration and smoothing efficacy
• Sweat resistance and long-lasting wear
• No-transfer performance
• Brilliance, gloss, and colour payoff (especially for lipsticks, glosses, and eye products)
• Volumising, lengthening, and curling effects (mascaras)
• Compatibility and performance on diverse skin tones (inclusivity)
• Sensorial and visual impact of new textures: metallics, hybrids, glossy finishes
• And more.

In a market driven by expressive aesthetics and responsible innovation, Eurofins C&PC delivers the scientific evidence behind the next generation of impactful, inclusive, and sustainable make-up products.

Accelerate quality control with near-infrared (NIR) spectrometry

In a highly competitive and innovation-driven cosmetic industry, rapid and reliable analytical techniques are essential to ensure product consistency and authenticity. Eurofins Cosmetics and Personal Care offers Near-Infrared (NIR) Spectrometry Testing, a robust, non-destructive method that delivers detailed molecular insights within 48 hours.

NIR spectrometry uses the near-infrared region of the electromagnetic spectrum to analyse the molecular composition of raw materials and finished products. Particularly well-suited for high-throughput environments, NIR facilitates batch-to-batch conformity assessments, raw material verification, and counterfeit detection with remarkable efficiency.

This method not only enhances process control but also supports faster decision-making across R&D, quality assurance, and regulatory functions. Our service is backed by Eurofins’ international regulatory expertise and stringent quality standards, offering a streamlined way to maintain product integrity.

By integrating NIR spectrometry into your quality management system, you gain a strategic advantage in ensuring product safety, uniformity, and compliance, key pillars of consumer trust.
