How can you formulate high-quality, consistent products for your consumers and extend the shelf life of the fats and oils you use? The answer: Oxynex® formulation stabilizers. Chemical deterioration caused by oxygen and resulting fatty peroxides can destroy your cosmetic products. Oxynex® helps to ensure the stability of your cosmetics by protecting them from pro-oxida-tive factors such as light, increase in temperature, metal traces, and more. Free radicals at the source of autoxidation chain reactions are inactivated by the intervention of anti-oxidants. Chemical deterioration is an auto-oxidative process caused by action of oxygen in air and can lead to rancidity. Adding antioxidants to your formulations will inhibit the auto-oxidation process, helping to stabilize and protect your formulations.

Oxynex

Stay ahead of the speedy sunscreen market with innovative Eusolex® portfolio. Your formulation needs are supported with the most extensive range of approved organic and inorganic UV filters worldwide. Enjoy your time in the sun! Organic Eusolex® UVA and UVB filters are essential components for formulating powerful protection from the sun. Their mechanism of action is based on a unique technology: The organic filters are sol-gel coated in Eusolex® UV-Pearls® and do not come in contact with sensitive skin, but provide optimal protection at the skin’s surface. Adding Eusolex® to applications such as traditional sunscreens, decorative cosmetics and moisturizers creates an optimal filter combination.

IR3535® repellent wasn’t just made for nature, it was inspired by it! In a claim approved by the EPA: “IR3535® is inspired from a naturally occurring amino acid” ß-alanine, which enables the repellent ingredient to boast a fantastic safety record.

In the US, it’s rated as a biopesticide that’s approved for all ages, so it can be used for protecting even small children. In the EU, the evaluation of the ingredient did not set an age restriction, and the WHO classified IR3535® repellent as Class U, which means “unlikely to present acute hazard in normal use (WHO 2004)”. The clear, odorless liquid can be used in lightweight formulations like lotions, sprays, and aerosols, allowing consumers’ skin to breathe easy.

Insect Repellents with IR3535® effectively keep pests like mosquitoes and ticks at bay, lessening the exposure to insect-borne diseases like Zika.
