Sorez™ HS 205 soil release polymer

2


Making hard surfaces easy to clean and to maintain is an importantconsumer requirement.

Sorez HS 205 polymer works by forming a barrier between common hardsurfaces and foulants.

The polymer reduces the tendency of soil to adhere to various ceramic, metaland plastic surfaces, making next-time cleaning easier.

Formulators of hard surface cleaners may use the polymer in formulations tosupport product label claims such as “Easy cleaning,” and “Surfaces staycleaner longer.”

Overview

3


A polymeric approach to cleaning hard surfaces offers a range of benefitsto 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

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

Overview

Compatible with most hard surface cleaning ingredients, Sorez HS 205polymer may be incorporated into a range of formulation types:

Kitchen cleanersPolymer is substantive to ceramic tiles

Works as an oily soil release polymer

Cleaning is easier, with less scrubbing and energy required

Toilet bowl cleanersPolymer functions as a long-lasting soil release technology

Offers ant-scale performance

All-purpose bathroom cleanerPolymer brings easy to clean benefits

Glass cleanersPolymer makes glass surface hydrophilic after cleaning

Prevents water beading and spots and streaks

When included in cleaning formulations at the recommended use levels, SorezHS 205 polymer helps consumers and professional house-keepers clean hardsurfaces more easily, with less effort and in less time compared to formulationswithout 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%

Function

9


Sorez HS 205 polymer helps hard surfaces stay cleaner, even afterrepeated soil and rinsing phases. The end result is easy next-timecleaning for consumers.

Creating demonstration formulations for various application areas (includingbathroom, toilet bowl, kitchen and glass), and applying various soil to thesehard surfaces, Ashland demonstrated easy cleaning after initial and repeatedrinsing, compared to a control.

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.
