Mastering the stability of active ingredients is no longer enough. Today, microencapsulation technologies make it possible to precisely define delivery parameters, orchestrate their diffusion over time, and trigger their release under specific conditions. This approach is fundamentally transforming product formulation in the skincare industry.
A technology at the core of intelligent delivery systems
Microencapsulation relies on embedding active ingredients within microcapsules, typically composed of a hydrophilic polymer shell surrounding a hydrophobic core that contains the functional ingredients.
This system acts as a protective barrier against external aggressors such as oxidation, light, or pH variations, while also enabling precise control over the release of active compounds.
Beyond simple protection, these advanced delivery systems now allow formulators to program ingredient behavior: gradual diffusion, on-demand activation, sequential release, or prolonged fragrance diffusion.
This ability to orchestrate the timing of actives paves the way for more effective, more stable formulations that are better aligned with real-world usage.
SalSphere® : controlled diffusion for long-lasting efficacy
SalSphere® technology is based on an encapsulation system designed to control the release of an ingredient to achieve long-lasting effects. It stands out for its ability to incorporate both hydrophilic and lipophilic actives within the same structure while maintaining their stability in aqueous formulations.
Through a gradual and controlled diffusion process, actives remain available for longer, improving overall efficacy while minimizing concentration peaks that can cause irritation. This controlled-release mechanism also protects sensitive ingredients from environmental stressors such as heat, light, and pH fluctuations.
HydroSal®: on-demand release
HydroSal® introduces a dynamic approach to active delivery with a system capable of releasing ingredients precisely when they are most needed. The technology relies on specific triggers such as moisture, pH, or friction, enabling activation directly upon contact with the skin.
This on-demand release mechanism ensures optimal precision: actives are protected until application, then released in response to real usage conditions. This approach enhances both formulation stability and ingredient efficacy, particularly for sensitive or highly functional actives.
MultiSal® : multi-phase sequential release
MultiSal® stands out for its ability to program the release of actives in multiple stages through a dual, or triple-phase microencapsulation system. This technology enables the combination of immediate, delayed, and prolonged effects within a single application.
In practical terms, actives can be released according to a predefined sequence, delivering multi-level performance: an instant effect upon application, followed by continuous diffusion over time and long-lasting benefits. This sequential release optimizes both ingredient stability and efficacy while simplifying routines by reducing the need for multiple product layers.
SalScent® : controlled and prolonged fragrance diffusion
SalScent® technology is specifically designed to encapsulate fragrances and essential oils to improve their stability and longevity. Fragrance compounds are trapped within porous structures and protected by a polymer matrix that controls their diffusion.
Fragrance release occurs progressively and in a controlled manner, particularly under the influence of external factors such as humidity. This system significantly extends scent intensity over time while reducing the amount of fragrance required in formulations. It delivers a more durable, stable, and high-performing sensory experience.
Toward complete orchestration of actives
These technologies illustrate a major evolution: the ability to orchestrate both the timing and mode of active delivery within a formulation. By combining controlled release, on-demand activation, sequential diffusion, and prolonged release, microencapsulation becomes a true performance engineering tool.
