synthesis of antioxidants, when subjected to stress by UVA/UVB or blue light exposure, through biomimetic pathways.
In vitro evaluation A skin biopsy from a healthy 32-year-old female was processed to study the effects of the active under UV and blue light stress. After treatment with or without product, biopsies were exposed to UVA/UVB or blue light, and antioxidant levels were measured. The antioxidant assay revealed that the
product significantly increased antioxidant levels, with a 42% increase under UV stress and a 28% increase under blue light stress. These results suggest that the active ingredient enhances the skin’s natural defence against oxidative damage from environmental stressors.
In vivo evaluation In vivo tests have confirmed the photostability of the active when use at 2 and 4%. Before and after irradiation of the formulation, the profile of absorbance at different wavelengths is the same which means that the formulation remains effective throughout its use. A sunscreen formulation with SPF 20
containing 2% of the active ingredient increases its SPF to 25. With 4% of the active, the SPF rises to 26.4.
This unique complex of microalgae and
cranberry seed oil exhibits remarkable protective activity, strengthening the skin’s natural defences against UV radiation and blue light.
Original multifunctional and SPF booster agent Natura-Tec Abysoft is a versatile active ingredient vegetable based that plays a key role in sun care formulations, known for its long lasting moisturizing properties and enhancing pigment dispersion. Recent studies have revealed its ability to
boost SPF by improving the distribution and stability of organic UV filters, resulting in more efficient sun protection and a pleasant texture. It is especially effective in sunscreen creams, where it enhances pigment wetting and prevents agglomeration, ensuring an even and stable formulation. This leads to a smoother texture and better aesthetic appeal in sunscreens.
www.personalcaremagazine.com This complex also optimizes the performance
of mineral UV filters like zinc oxide and titanium dioxide, which often struggle with clumping. Its pigment-wetting properties ensure better stability and more effective UV protection, while also reducing the grainy feeling associated with mineral filters. The biomimetic structure of the ingredient
enhances skin compatibility, improving spreadability and absorption, which contributes to a lightweight, comfortable finish without compromising sun protection. In vitro studies show that Natura-Tec Abysoft
can increase SPF by up to 18.6% with just 2% of use and up to 66.8% with 10% of use, while, in vivo, it increases SPF by ten points. Beyond sun protection, it enhances skin
hydration and elasticity, maintaining a soft, supple texture even after sun exposure. Its protective barrier function prevents dehydration, providing maximum pleasant afterfeel and radiance while reinforcing the skin’s defences against environmental aggressors.
Biodegradable and eco-friendly texturizing agent Silicones are widely used in sun care products for their smoothing effect and ability to enhance UV filter dispersion. However, concerns about their environmental impact have led to a growing demand for eco-friendly alternatives. The plant-based emollient Natura-Tec Plantsil,
derived from olive derivatives, meets this need by offering an enhanced sensorial effect, dispersion aid, hydration and skin barrier protection as well as sustainable and biodegradable considerations. Thanks to its unique texture, it perfectly
replicates the silky feel and softness of synthetic silicones without leaving a greasy residue on the skin. Its excellent compatibility with sunscreen
filters and other components ensures an homogeneous distribution, optimizing their effectiveness and providing more uniform protection against harmful radiation. Its natural structure provides an excellent
biocompatibility with the skin and helps restore its suppleness and prevent dehydration caused by sun exposure. Unlike traditional silicones, which can affect skin breathability, it provides a lightweight and
comfortable application, making it ideal for daily use in sunscreens and protective skincare. As a 100% plant-based ingredient, it is fully
biodegradable and aligns with the environmental commitments of modern cosmetics. Its integration into cosmetic formulations not
only enhances sensoriality but also promotes a more skin-friendly and eco-conscious approach to sun care. Thanks to its biomimetic structure, it exhibits high affinity with the skin’s natural lipids, allowing optimal absorption of UV filters and better diffusion of antioxidant actives. By ensuring a homogeneous distribution of
protective agents, it optimizes the effectiveness of sunscreen formulas while enhancing their sensory appeal. Its silky touch and non-greasy finish guarantee a pleasant application experience and perfect compatibility with modern sun care formulations. Furthermore, it plays a key role in formulation
stability, preventing the segregation of lipophilic actives and extending their effectiveness on the skin. Its emollient properties ensure long- lasting hydration, reinforcing the skin barrier and reducing dehydration caused by sun exposure.
Conclusion The combination of these products paves the way for a new generation of high-performance, natural sun care solutions. These three ingredients illustrate Natura-Tec’s commitment to greener and propose more effective cosmetics. By reducing the use of synthetic UV filters
through natural SPF boosters, long lasting moisturizer and offering a sustainable alternative to silicones, they enable the development of sun care products that are both effective, pleasant to use, and environmentally friendly. With this trio of ingredients, sun protection
enters a new era: one of natural performance and refined sensoriality.
