Sun Protection that Performs – Sustainably, Effectively, Naturally

Smart Sun Protection: What today’s skincare consumers expect

Sun protection has become an essential part of daily skincare – consumer expectations and awareness about the importance protecting skin against UV radiation are higher than ever. Modern users are looking for products that offer reliable broad-spectrum protection, but also demand pleasant textures, skin compatibility, and sustainable ingredients. In response, innovative formulations combine powerful UV filters with smart supporting ingredients to deliver high performance without compromise. SLI Chemicals offers you a complete range of ingredients such as:

  • Zinc Oxide based UV filters
  • Concentrated fluid emulsions for sun products
  • UV protection boosters
  • Emollient esters
  • Emulsifiers
  • Starches

Zinc Oxide – Safe, excellent physical mineral based protection with broad spectrum

Zinc oxide is a trusted mineral UV filter that offers broad-spectrum protection against both UVA and UVB rays. It works by physically reflecting and scattering harmful radiation, making it ideal for sensitive skin and those seeking a more natural approach. Thanks to modern microfine technology, zinc oxide can now be used in formulations that leave reduced white cast, while still providing highly effective sun defense.

Under the brand Eclipse® our partner Uviva Technologies offers the latest genaration of zinc oxide with broad range powders and “ready to use” dispersions providing the best transparency without compromising UV performance.

  • Highest transparency and superior UV protection
  • Outperforms industry benchmarks across the UV/VIS spectrum
  • Lowest impact on formula viscosity and aesthetics

Concentrated fluid emulsions for sun protection products

RESCONCEPT® SUN manufactured by Sharon Personal Care is a smart solution that provides a ready-to-use solution for sun care emulsion formulation. With particular attention to the undersea environmental biodiversity, it is a complete range of sunscreens that follow the Hawaiian ban guidelines, with a special attention to the sensory profile offering following benefits:

  • Reef-friendly sunscreens
  • UVA/AVB corrent ration
  • Water resistant
  • Sustainable
  • Moisturizing probiotic
  • Detox pinus extract
  • Microplastic free
  • Vegan
  • Biodegradable

RESCONCEPT® SUN line technology allows the preparation of hyper-fluid ( < 150 cps) concentrated emulsions, characterized by a strong stability, easily to be diluted in water and used in different applications such as milk, sprayable lotion, Bag on Valve (BOV) fluid emulsions.


UV Boosters – Enhanced protection with less filter load

UV boosters are innovative ingredients that amplify the performance of UV filters, allowing formulators to achieve higher SPF values with lower filter concentrations. They also allow to target higher SPF values and to overcome SPF limits of certain UV filters. They support lighter, more skin-friendly formulas that still deliver robust protection – while also reducing potential environmental impact. UV boosters are a key component of smart, efficient, and responsible sun care.

With KanShield Max and Ferulishield we offer two very effective solutions for your new sun care innovations.


Emollients – For skin comfort and sensory appeal

Emollients play a crucial role in the feel and performance of sunscreen products. A well-chosen composition of emollient ensures that products spreads smoothly, absorbs easily, and leaves the skin feeling soft and nourished, without greasiness.

They also help to overcome whitening challenges typically associated with mineral based filter systems. In addition, emollients help support the skin’s natural barrier function, especially important under sun stress. Ingredients like Gilsolide® HVN offer a sustainable, silicone-free alternative with excellent spreadability and sensory benefits.

Emulsifiers – Ensuring stability and performance

Emulsifiers are essential in sunscreen formulations, as they enable the stable blending of oil and water phases into a uniform emulsion. This stability is crucial not only for the product’s shelf life, but also for the even distribution of UV filters on the skin – which directly affects the effectiveness of sun protection.

The right emulsifier system also influences the product’s texture, absorption rate, and water resistance, helping to create sunscreens that are both efficacious and pleasant to use. Modern, mild emulsifiers can further enhance skin tolerance and contribute to the overall sensory experience.

EMULPHARMA® MIMESIS RSPO MB for example is a real multitasking emulsifier: It forms skin-like fluid and sprayable structures becoming a real carrier for active ingredients: It is not just an emulsifier, it is the beauty–driver. It is cold processable allowing to save energy during the manufacturing process.

NATURAL BOILING-RESISTANT STARCHES – Multifunctionality in sensory and performance

Distarch phosphates are modified cook stable starches derived from corn or rice. CORN PO4 PH“B“ and RICE PO4 NATURAL are white, ultra fine powders and the particles have a remarkably large surface area. These starch granules efficiently adsorb substances dissolved in the water phase. They are approved as natural cosmetic ingredients by COSMOS. They can add to your formulation properties such as:

  • Silky and nourishing feel – DISTARCH PHOSPHATES reduce the greasiness and stickiness of emulsions
  • Improved spreadability of emulsions
  • Long-lasting moisturizing effect and slow releases  – DISTARCH PHOSPHATES ‘lock in’ moisture adsorbed from the water phase of your formulation. When applied, this water is released over a long period, providing moisture to the skin throughout the day.
  • Mattifying effect


Distarch phosphates are insoluble in every solvent and are compatible with all cosmetic raw materials such as active ingredients, deodorizing agents, preservatives etc.
