Monomeric stabilizer
for use in plastics receives FDA approval
First in its class, a monomeric hindered amine light stabilizer from
BASF obtains FDA approval for use in plastics with food contact applications.
BASF’s light stabilizer Uvinul* 4050 H is the first monomeric HALS
worldwide to obtain a Food Contact Notification (FCN) for the use in plastics
with food-contact. The FCN is granted by the United States Food and Drug
Administration (FDA). Uvinul 4050 H may be used in polypropylene, polystyrene,
styrene copolymers and acrylonitrile copolymers (including ABS) that come
into contact with foodstuffs. Applications for Uvinul 4050 H include woven
fiber sacks such as bulk bags, flour sacks and corn (maize) sacks, electrical
equipment such as kitchen equipment, thermoformed packaging such as yoghurt
beakers and disposable cutlery.

Uvinul 4050 H is;
... approved for use at a concentration of up to 0.5 % in polystyrene,
styrene copolymers and acrylonitrile copolymers. It is also approved for
use at a concentration of up to 0.25 % in polypropylene in contact with
all types of foodstuffs except those with an alcohol content of more than
8 %. The requirements and definitions for individual plastics in FDA Regulations
21 CFR 177.1640 (polystyrene), 21 CFR 177.1810 (styrene copolymers), 21
CFR 181.32 (acrylonitrile copolymers) and 21 CFR 177.1520 (polypropylene)
must be observed when it is employed as a light stabilizer for food-contact
applications.
... a light stabilizer that belongs to the group of lowmolecular-mass
sterically hindered amines (monomeric HALS). It scavenges the free radicals
that are formed when plastics are degraded by exposure to light and renders
them harmless. This helps to prevent further degradation of the polymer,
and it retains its initial visual appearance and mechanical properties
much longer.
... also very effective for use in fibers and injection molding from plastics
such as polypropylene or polyamide. Its high thermal stability allows
it to be used with no problems in plastics processing.
A low-molecular-mass HALS offers the most effective solution for stabilizing
plastics such as ABS and polypropylene. Up until now, compromises have
had to be made because of the lack of approval for stabilizers for plastics
intended for use in food-contact applications. Following the approval
of Uvinul 4050 H, plastics for food contact applications can now fulfill
the highest standards of resistance to weathering.
Uvinul 4050 H completes BASF’s comprehensive range of light stabilizers
that are approved for use in food-contact applications. BASF’s customers
now have the opportunity to use exclusively light stabilizers with food
contact approval in their plants.
The product range of BASF's Performance Chemicals for Coatings,
Plastics and Specialties business unit includes pigments, preparations
and dyes, binders and crosslinkers, light stabilizers and process chemicals.
