Setting new standards for sunscreen film formers PERSONAL CARE
As consumer expectations for sun care evolve, the demand for high-performance, environmentally conscious sunscreens is reshaping formulation strategies. Among the most critical attributes driving
innovation is water resistance - a feature that enhances product efficacy and builds consumer trust during swimming, sweating and outdoor activities.
The launch of NATURALUXE™ MFF, a
new and patent-pending film former, marks a significant advancement in sunscreen formulation. Film formers are essential for creating a uniform, flexible, and durable layer on the skin, helping to lock in UV filters and maintain protection under challenging conditions. NATURALUXE™ MFF delivers improved substantivity, sensory appeal, and compatibility with broad-spectrum filters—addressing both performance and aesthetic expectations.
Beyond UV: the rise of multifunctional, eco-conscious sunscreens Recent market research reveals a significant shift in global consumer priorities when it comes to sun care. Today’s consumers are increasingly seeking products that are not only effective but also gentle on the skin and environmentally responsible. According to Mintel, 34% of consumers in
the US are actively choosing sunscreens that are eco-friendly, looking for reef-safe claims and sustainable packaging.1
Moreover, nearly
74% are willing to pay a premium for products formulated with natural ingredients or benefits.2 In China, 56% of sunscreen users express
a strong interest in natural-origin ingredients, reflecting a broader trend toward clean beauty.3 Water resistance has also emerged as a key
differentiator, with 63% of global sunscreen launches now featuring this claim.4

nearly half of new launches in 2024 highlighted water resistance as a primary benefit.5 Texture and skin feel are equally important –
especially in Thailand, where 60% of consumers who use multiple sun care products report concerns about greasiness and stickiness, and 40% worry about product effectiveness.6 This growing demand for multifunctional
sunscreens – offering high SPF, water and sweat resistance, broad-spectrum protection, and suitability for sensitive skin – poses a complex challenge for formulators. Delivering all these benefits in a single, sustainable formulation requires advanced ingredient technologies and a deep understanding of consumer expectations.
The need for next-generation film formers Traditional natural polymers have long been used in sunscreen formulations, but they often fall short in delivering the performance consumers expect today. While synthetic film formers are known for their stable performance, their issues such as suboptimal sensory properties, microplastic pollution and non- biodegradability have led to declining consumer acceptance. Natural film formers present a more

sustainable alternative, though they often lack the robustness required for consistent sunscreen efficacy. Naturaluxe™ MFF was developed as a next-generation solution. This patent-pending, biodegradable
polymeric emollient provides superior film formation for smooth, flexible, and long-lasting

coverage. It enhances SPF retention and water resistance even after repeated water exposure, while maintaining excellent compatibility with both mineral and organic UV filters, ethanol and a wide range of emollients. Its light, non-tacky skin feel encourages
proper application and re-application, ultimately improving both product performance and user satisfaction.
Technical innovations and industry impact Naturaluxe™ MFF represents a breakthrough in film-forming technology, combining sustainability, compatibility, and high- performance attributes to meet the evolving demands of the sun care industry.
Biodegradable and sustainable With approximately 80% natural origin content, Naturaluxe™ MFF offers a biodegradable and non-persistent alternative to conventional synthetic, polymeric film formers, which can remain in the environment for decades. This significantly reduces environmental impact and aligns with growing regulatory and consumer demands for sustainable ingredients.
Versatile compatibility Its unique chemistry allows for broad compatibility across various formulation types, including alcoholic sunscreens, oil-in-water (O/W) emulsions, and a wide range of solvents such as C12-15 Alkyl Benzoate, Caprylic/Capric Triglycerides, Isododecane, and ethanol. As a cold-processable liquid, it simplifies manufacturing and maintains the aesthetic integrity of formulations by not affecting colour or odour.
