Alcoguard® H 5941 polymer

Readily biodegradable hybrid polymer

Alcoguard® H 5941 polymer is a sustainable and versatile In Automatic DishWash (ADW)

hybrid polymer. This novel product based on unique and
patented technology is readily biodegradable and derived from With the newest amendment (No 259/2012) of the EU

A greener choice play an even more important role. Polycarboxylates, which are
used as co-builders need to perform to the highest standard
Alcoguard® H 5941 polymer represents the next generation of with weaker builders replacing phosphates. They prevent the

molecule to make the hybrid polymer. Designed to prevent
scale formation in detergent applications such as automatic Polycarboxylates generally used in ADW formulations provide:
dishwash, laundry and hard surface cleaning, Alcoguard® H • Threshold stabilization (polymer sequesters Ca2+ and Mg2+
5941 polymer is particularly effective at minimizing filming and to prevent the formation of insoluble salts)
spotting in zero phosphate automatic dishwash formulations • Dispersion (polymers disperse particles using steric
and works as effectively as synthetic copolymers. stabilization and electrostatic repulsion)
• Crystal growth inhibition

Environmental benefits Alcoguard® H 5941 polymer provides the same functions as

synthetic polycarboxylates in ADW formulations.
Alcoguard® H 5941 polymer is primarily made from
polysaccharides, not petrochemicals. This eco-premium
technology performs similarly to widely available synthetic
petrochemicals but is based on 75% renewable resources. It
has a significantly lower carbon footprint (lifecycle assessment
available) than traditional petrochemical based polymers.

Hybrid polymers are significantly more biodegradable than P-AA-MA Alcoguard® H Sulfonated No polymer
typical synthetic polymers, which makes them an attractive copolymer 5941 copolymer
environmentally friendly alternative to traditional polymers.

In Hard Surface Cleaning (HSC) Bio-based and readily biodegradable

Due to the chemical structure of the hybrid polymers, mixing Most polycarboxylates used as builders, antiscalants
natural and synthetic monomers, they show high stability in and dispersants in cleaning applications are synthetic
alkaline conditions, which makes them suitable for household polycarboxylates which have very limited biodegradation
as well as Industrial & Institutional (I&I) cleaning applications. and no bio-based content. Alcoguard® H 5941 polymer is
different. It is majority biobased and is readily biodegradable
A small addition of Alcoguard® H 5941 polymer in HSC in the environment, characteristics that are desired by
products boosts the overall cleaning performance of the today’s consumer. A key deliverable in the development
formulation. of this product was to achieve the same or enhanced
technical performance in cleaning formulations as synthetic
polycarboxylates, while being more sustainably sourced, with
lower overall impact on the environment.

Alcoguard® H 5941 polymer has been reviewed by EPA’s Safer

Choice Program and qualifies for use in Safer Choice-certified
P-AA-MA Alcoguard® H Market No polymer products. Alcoguard® H 5941 polymer is also suitable for EU
copolymer 5941 reference Ecolabel requirements.
