required to achieve uniform pigment distribution, enabling more vibrant and consistent colour in multifunctional products. Sensorial excellence is not merely a cosmetic benefit, it directly influences consumer behaviour. Products that feel pleasant are more likely to be applied generously and reapplied throughout the day, leading to better protection.
Multifunctionality for simplified formulation design As consumers gravitate toward “less but better” routines, formulators are seeking ingredients that can perform multiple roles simultaneously. Multifunctional materials simplify ingredient lists, reduce formulation complexity, and support the creation of streamlined, consumer friendly products. Ingredients that act as dispersants, film
formers, solvents, emollients, and conditioners offer significant advantages in sun care formulation. Their versatility allows formulators to reduce the number of raw materials needed, improve production efficiency, and create more stable, elegant products. The ability to remain liquid at low
temperatures is particularly valuable for cold process emulsions. Cold process refers to formulating products at room temperature without applying heat. Ingredients are mixed directly, using specifically designed emulsifiers or stabilizers to create stable formulations. This approach reduces energy consumption, simplifies manufacturing, and helps preserve heat-sensitive ingredients, making it a more sustainable and efficient formulation method. By formulating at low temperatures, heat-sensitive UV filters and boosters maintain their integrity and performance, reducing the risk of degradation. It also allows for better control over the dispersion of mineral filters like TiO2
, which is critical for
achieving stable, homogeneous systems and consistent SPF protection.
Advantages in sunscreen stick formulations Sunscreen sticks illustrate the value of multifunctional materials particularly well. These formats require ingredients that can stabilize high loads of mineral filters, maintain smooth glide, and support strong film formation. The right emollient can ensure stable suspension, reduce sedimentation, and improve application aesthetics. Sticks formulated with multifunctional
materials typically exhibit softer application, less drag, and more even payoff. They also benefit from enhanced film formation and potential SPFboosting effects, making them ideal for facial application, sports activities, and children’s sunscreens. Their portability and precision make them a popular choice for on the go protection, and their water resistant performance aligns with consumer expectations for real world durability.
Sustainability remains important Sustainability has become a central consideration in sun care formulation. Consumers increasingly seek products made with renewable, traceable

ingredients that minimize environmental impact. Materials derived from European rapeseed or other natural feedstocks are better for the planet and offer a reduced carbon footprint. A 100% natural origin index supports clean
beauty positioning and aligns with regulatory and consumer expectations for naturality. At the same time, these materials must deliver high performance to compete with traditional petrochemical emollients. Next-generation natural ingredients that combine sustainability with technical excellence are therefore highly valued in modern sun care.
Conclusion As the sun care category continues to evolve, the demand for high performance, multifunctional ingredients will only grow. Consumers expect
sunscreens that deliver high protection, elegant textures, and durability, while aligning with values such as sustainability, naturality, and transparency of the supply chain. Next-generation emollients and dispersants
play a central role in meeting these expectations. Their ability to improve mineral and organic UV filter performance, enhance film formation, elevate sensoriality, and support more sustainable manufacturing enables formulators to create sunscreens that are both more protective and more enjoyable to use. In this context, solutions that combine these
benefits into a single ingredient, such as Radiastar 1436 which is a multi-branched C36 Guerbet alcohol of 100% natural origin, offer a particularly relevant approach, addressing multiple formulation challenges simultaneously. PCM
