Croda reveals INCI name for bio hair repair product


Croda has confirmed the official INCI (International Nomenclature Cosmetic Ingredient) name for its biomimetic hair repair ingredient, KeraBio K31.


The INCI name is Hydrolysed


sr-(Tripeptide-137 Hexapeptide-40 sh-Polypeptide-184 sh- Polypeptide-146). KeraBio K31 is a novel, bio-


based product said to outperform the hair repair benefits of animal- derived keratin. The biomimetic bond builder


delivers a vegan keratin recharge at the molecular level, elevating hair strength beyond repair. This pioneering innovation


is a great example of close cooperation across Croda’s global R&D, biotech, operations and marketing teams, supported by key external scientific contributors: The team at Croda’s


Biotechnology Research and Technology site, Daresbury, UK, led the creation of the novel keratin structure that met the performance and sustainability specifications. Additional insights about


KeraBio K31’s unique mode of action, particularly its role in forming internal hair bonds were


developed by the UK R&D team strengthened by data generated in collaboration with trusted external partners, adding depth to its understanding of this advanced technology. In parallel, Croda’s R&D team


in the USA delivered robust in vitro performance data, demonstrating KeraBio K31’s ability to significantly improve hair strength and resilience, validating its benefits in real-world application. Supporting the scale-


up process, Croda’s Process Innovation team brought critical expertise to ensure KeraBio K31 was production-ready at a commercial scale, preserving its integrity and performance in


formulation. Sandra Breene, President of


Consumer Care, said: “KeraBio K31 is a strategic response to evolving consumer expectations around efficacy, sustainability, and science-led performance. “This launch is the result of


extensive collaboration across our global business. “By bringing together our


innovation, sustainability, and formulation teams, we have developed a biomimetic keratin technology that not only reflects our commitment to pioneering high-performance beauty solutions but also demonstrates how we innovate together to shape the future of hair care.”


DSM-Firmenich unveils film-forming UVB filter


DSM-Firmenich has taken the wraps off Parsol SLX, a film- forming polymeric UVB filter that combines sun protection with a sensorial experience. When combined with


pigmentary UV filters, the ingredient is said to enhance sunscreen performance by up to 50% while maintaining a superior sensorial experience on the skin. DSM-Firmenich says, unlike


traditional sun protection that often demands heavy formulations to ensure effective UV defence - leaving the skin greasy and uncomfortable – Parsol SLX enhances SPF performance by forming an invisible, uniform shield. It is said to be the ideal


partner for daily skin care routines on preventing

delivering high SPF efficacy with a lightweight, elegant skin feel. “Its unique polymeric


structure allows for reduced ingredient concentration while maintaining superior protection, making it a smart and sensorially pleasing choice for modern sun care formulations.” Parsol SLX also protects hair


premature skin ageing caused by sun exposure, effectively delivering both superior comfort and efficacy. “Today’s consumers are


increasingly seeking sun protection solutions that minimize chemical load without compromising on performance,” added Tina Vogt, Director Global Marketing Sun Care. “With Parsol SLX, we’re proud


to offer a future-proven UVB filter that meets this demand—


from photodamage, preventing colour fading, and providing a lightweight, luxurious feel, according to Melanie Waeckel, Global Senior Marketing Manager Hair Care. “Instrumental tests


demonstrate up to 32% colour retention of red permanent hair. Leveraging the smart film- forming technology, it delivers UV performance, leaving hair soft and smooth,” she added.


Eczema-prone derm standard


unwrapped MyMicrobiome has launched MyMicrobiome Derm Standard – Eczema, the world’s first microbiome-oriented standard specifically developed for products for eczema-prone skin. The certification assesses the impact of cosmetic and dermatological products on the unique and sensitive microbiome of people with atopic dermatitis (AD). The new eczema standard


comprises a series of advanced laboratory tests conducted in certified laboratories in Switzerland and Germany.


The assessment determines


whether a product can reduce or inhibit harmful S. aureus strains while preserving beneficial commensal bacteria that protect the skin barrier. Products that meet all


criteria are allowed to carry the Microbiome-Friendly Derm Seal, which stands for scientific validation and consumer confidence. The first products have already


been successfully certified according to the eczema standard. Dr. Kristin Neumann, co-founder


and CSO of MyMicrobiome, said: “Skin prone to eczema needs more than just mild formulations—it needs products that actively support microbial balance. “The overgrowth of certain


S. aureus strains is a major factor in flare-ups, but at the same time, preserving beneficial bacteria is essential for long-term skin health. Eczema, particularly atopic AD,


is one of the most common chronic inflammatory skin conditions worldwide. It affects people of all ages and


significantly impairs quality of life due to its chronic course, frequent flare-ups, and associated physical discomfort. A hallmark of AD is a weakened


skin barrier, which leads to increased transepidermal water loss and greater susceptibility to allergens and microbes.
