Sorez™ HS 205 soil release polymer

Sorez™ HS 205 soil release polymer Overview Making hard surfaces easy to clean and to maintain is an important consumer requirement. Sorez HS 205 polymer works by forming a barrier between common hard surfaces and foulants. The polymer reduces the tendency of soil to adhere to various ceramic, metal and plastic surfaces, making next-time cleaning easier. Formulators of hard surface cleaners may use the polymer in formulations to support product label claims such as “Easy cleaning,” and “Surfaces stay cleaner longer.”

Sorez™ HS 205 soil release polymer Overview A polymeric approach to cleaning hard surfaces offers a range of benefits to consumers. Very efficient soil release Effective soil repellency Inhibition of scale formation Less energy and time required to clean hard surfaces Surfaces stay cleaner longer

Sorez™ HS 205 soil release polymer Overview A copolymer based on vinyl pyrrolidone/dimethylaminoethylmethacrylate, Sorez HS 205 polymer employs known monomer properties to assure: Adhesion to metal, ceramic and plastic substrates Substantivity across a range of surfaces Water solubility Controllable, clear films Gloss improvement

Sorez™ HS 205 soil release polymer Overview Compatible with most hard surface cleaning ingredients, Sorez HS 205 polymer may be incorporated into a range of formulation types: Kitchen cleaners Polymer is substantive to ceramic tiles Works as an oily soil release polymer Cleaning is easier, with less scrubbing and energy required Toilet bowl cleaners Polymer functions as a long-lasting soil release technology Offers ant-scale performance All-purpose bathroom cleaner Polymer brings easy to clean benefits Glass cleaners Polymer makes glass surface hydrophilic after cleaning Prevents water beading and spots and streaks

Sorez™ HS 205 soil release polymer Function When included in cleaning formulations at the recommended use levels, Sorez HS 205 polymer helps consumers and professional house-keepers clean hard surfaces more easily, with less effort and in less time compared to formulations without polymer. Product application Recommended use level Kitchen cleaner 0.5 – 2.0% Toilet bowl cleaner 0.5 – 2.0% Soap scum removers 0.5 – 2.0% Glass cleaners 0.5 – 1.0%

Sorez™ HS 205 soil release polymer Efficacy tests Sorez HS 205 polymer helps hard surfaces stay cleaner, even after repeated soil and rinsing phases. The end result is easy next-time cleaning for consumers. Creating demonstration formulations for various application areas (including bathroom, toilet bowl, kitchen and glass), and applying various soil to these hard surfaces, Ashland demonstrated easy cleaning after initial and repeated rinsing, compared to a control.

Sorez™ HS 205 soil release polymer Summary Easy next-time cleaning Polymeric barrier formed between hard surfaces and various soils simplifies next-time cleaning. Clear films formed on surfaces reduce the tendency of soils to adhere. Including Sorez HS 205 polymer in formulations between 0.5% and 1.5% (formulation dependent) offers consumers the ability to clean surfaces in less time, with less effort, compared to formulations without polymer. Sorez HS 205 polymer may be used in a range of hard surface cleaning formulations to support novel label claims. Efficacy tests show significantly better next-time cleaning performance than a control polymer using various prototype and commercial formulations.
