Antimicrobials Biocides

CEFIC has estimated that 60% of all the active biocidal ingredients used in all materials in the EU are likely to be withdrawn within three years because of the Biocidal Products Directive. 

With registration of a new active ingredient costing 5 M euros and the whole process taking several years, there are not expected to be very many new candidates for some time. Any new environmental products are likely to be more expensive, and to contribute to market growth in value terms. 

In many advanced countries there are legal restrictions on the claims that can be made about antimicrobials, because they are not all completely effective in killing all microorganisms. So expressions like self-sterilising , hygienic and germ-ifee are associated with specific levels of performance and not automatically acceptable just because a biocide is used. As a result, there has been considerable interest in the development of appropriate test methods for measuring antimicrobial efficacy. 

A survey sponsored by Avecia and carried out in the USA ascertained the general public s opinion of antimicrobials in plastics products. It showed support for their use in public spaces (hospitals, restaurants, hotels, aircraft) and in products associated with babies and yoimg children, but there was less enthusiasm about the need to protect products used in private homes. Respondents were willing to pay a small premium (up to 10%) over the price of improtected articles, but not a large one.

Protect against mould, mildew, fungi, and bacterial growth. Should be migratory to replace consumed material. Biocides are most commonly used in PVC due to its plasticiser content and use in outside applications. See Antimicrobials, Biocides.

Pesticides and antimicrobials (biocides) are used in a number of plastics construction materials, mainly to provide resistance to the growth of microorganisms. One common example is their use in a number of PVC and PU grades. PU is commonly used for roofing membranes in construction [22], and several plasticisers, lubricants, thickening agents and fillers that are used with it can support microbial growth effectively.
