Innovation in detergents Translating customer needs into product solutions Equity Story Clariant 2017 44 Aesthetic monodose units Out of the wash products Less rinsing Less energy – wash at low temperature Less water – less rinsing Less waste – concentrates Fabric and colour maintenance Fresh scent in wear and storage Easy to formulate polymers in high surfactant loads Efficient dispersion and repelling of soil in the wash Efficient removal of fats and greases at low washing temperatures Subsequent cleaning benefits (soil release) Fresh scent retention Prevention malodour Viscosity adjustment in low surfactant or highly concentrated formulations Convenience Sustainability Well-Being Global challenges Consumer trends and needs Unmet needs targeted by TexCare®

45 TexCare® Polymers for laundry detergents Multifunctional TexCare polymers prevent soil redeposition on fabrics for improved whiteness. Can also close performance gap at low washing temperatures in regular use via soil release effect Improved polymer pH stability for heavy duty liquid detergents Synergistic effects with other detergent ingredients Challenge Opportunities Addresses needs of fast-growing markets in developing countries (water scarcity) and global sustainability trend (energy saving, water saving) Pressure on large soapers to innovate and differentiate versus private labels Further exploit and augment Clariant’s expertise in soil-release polymers Innovation Improved performance or reduced formulation cost with unchanged performance Low temperature washing ability Tailor-made solutions in joint developments Value Creation / Customer benefits Sustainability trend towards less water consumption and lower washing temperature decreases the performance of detergents (greying of fabrics and impaired oily/fatty stain removal) Maintain detergent performance at lower cost in a competitive environment Equity Story Clariant 2017
