Seppic ‘flags link between exosome volume, efficiency’


French cosmetic active maker Seppic has claimed to demonstrate a direct link between exosome concentration and efficacy in two of its flagship ingredients. Driven by growing interest in non-


invasive cosmetic solutions inspired by aesthetic dermatology and the role of exosomes as intercellular messengers, Seppic has published new data on Celtosome Crithmum Maritimum (INCI: Crithmum Maritimum Callus Culture Filtrate) and Celtosome Eryngium Maritimum (INCI: Eryngium Maritimum Callus Culture Filtrate). Developed at the Pontrieux


site in Brittany (France), Seppic’s Celtosome plant biotechnology native and undifferentiated plant cells from halophyte species. This expertise yields a pure


biomass within which the presence of


approximately 4,000 exosomes per plant cell has been quantified. This measurement ensures a


standardized concentration of 50 million plant exosomes per microlitre of active ingredient, providing a highly defined matrix to optimize skin targeting. The anti-ageing Celtosome


Eryngium Maritimum ingredient delivers 720 million exosomes per gram of formula at a recommended use level of 0.05%. Specific evaluations conducted on its isolated exosome fraction highlight


their active role in the structural support of the skin, demonstrating up to a +34%2


stimulation of Collagen I


synthesis in fibroblasts. This key biological contribution


directly participates in the performance of the global active ingredient, which also shows a +103% increase in dermal hyaluronic acid production as well as +34% in elastin. This comprehensive structural


activity translates clinically into a significant smoothing effect, measured by a 12% reduction in the surface area of crow’s feet wrinkles after 28 days of application. Dedicated to skin clarity, radiance,


and longevity applications, Celtosome Crithmum Maritimum leverages this same cellular potential, delivering 1.44 billion exosomes per gram of cream when used at 0.1%.


Gattefossé ramps up Texas production


Gattefossé has achieved globally standardised and verified production of cosmetic ingredients at its United States manufacturing facility in Texas. Five cosmetic ingredients have


now achieved manufacturing equivalency at its Lufkin site. Building on EFfCI certification for


personal care products, the Lufkin site now manufactures cosmetic ingredients according to the same quality, analytical and regulatory standards applied across Gattefossé’s global production network. Each validation is supported by


a complete technical equivalence file, including analytical validation, stability data, and regulatory documentation to ensure seamless integration into customers’


development and commercialization programmes. The five ingredients are: Emulium Mellifera MB, a


natural oil-in-water emulsifier that adapts to different skin types and environmental conditions while delivering outstanding sensory properties. Compritol 888 CG MB, a


multifunctional texturizing agent used as a consistency enhancer, oil-phase thickener and stabilizer in skincare, make-up and sun care formulations. Emulium Delta MB, an oil-


in-water emulsifier offering high formulation flexibility together with a soft, velvety feel. Plurol Diisostearique CG, a water-


Naolys earns ISO 9001:2015 certification


Naolys has earned ISO 9001:2015 certification, recognising its products are safe, reliable and of good quality. Founded in Bordeaux, France


in 2003, Naolys is a pioneer in plant cell culture biotechnology. After more than 20 years


of scientific innovation and a portfolio of nineteen patents,


maintaining the highest standards of quality, consistency and traceability has become a natural extension of Naolys’ biotechnology expertise, it said.


ISO 9001:2015 certification


confirms that the same level of rigour behind Naolys’ innovations extends across the entire organisation, from research and development to

reflects Naolys’ commitment to delivering innovative biotechnology solutions supported by robust processes, continuous improvement and long-term reliability for our partners worldwide,” said Naolys CEO Rachid Anane.


in-oil emulsifier particularly suited to make-up and sun care formulations thanks to its minimalist composition and formulation versatility. LAS MB, a versatile, non-ionic


surfactant suitable for skin and hair care formulations, including creams, lotions, wipes and microemulsion systems. “The validation of our first


ingredients at our Lufkin facility is a major achievement for our portfolio,” said Ben Blinder, chief operating officer at Gattefossé USA. “We are directly answering


our partners’ need for supply chain resilience and dependable domestic sourcing in an increasingly unpredictable global market,” he added.


C16 Biosciences unwraps precision


fermentation trio New York City-based C16 Biosciences has launched three precision fermentation-derived ingredients for beauty and personal care: TorulaSilk, Torula Butter, and the Torula Carotenoid Complex. TorulaSilk features a broad fatty


acid profile spanning C8 to C24, TorulaSilk combines the sensorial elegance of lightweight lipids with the conditioning benefits of heavier triglycerides. It is said to provide exceptional


spreadability, fast absorption, and a dry-touch finish; it also functions as a fermentation-derived replacement for D5/D6 silicones. Torula Butter provides rich


conditioning while minimizing the waxiness, drag, and scent often associated with traditional butters. With a 32°C melt point, it


melts at skin temperature for a soft application that leaves skin nourished without heavy residue. The butter contains naturally


occurring sterols that support the skin barrier and provide essential structure to solid, semi-solid, and liquid products. Torula Carotenoid Complex harnesses the power of fungal- specific carotenoids torulene, torularhodin, and beta-carotene. These potent antioxidants


defend formulations against oxidative degradation and replenish vital molecules in the skin that are typically depleted by UV exposure and environmental stress. Together with the previously


released Torula Oil and new food ingredient Cocoa Butter Equivalent, C16’s ‘Palmless’ product range now offers five commercial ingredients. “Torula Oil has become a go-to


ingredient for formulators across skin care, suncare, body care, and colour cosmetics,” said David Heller, founder and COO of C16 Biosciences. “These three new ingredients


provide those same brands a full biotechnology-derived toolkit, from high-potency actives to functional emollients and butters.”
