1.7 Catechin Car-Air-Filter and Air Cleaning System
It helps to reduce odorous volatiles inside the car. This
is used widely in vehicles manufactured by Suzuki
Motor Corporation, Japan. Further, Matsushita Electric
(Panasonic) use this compound in air conditioning

spread of bacteria and viruses inside the room.
1.8 Antiflu Mask
A Catechin air filter has been fitted in a facial mask
which is used mainly for protecting influenza virus and
also has a preventive effect against hay-fever in Japan.
1.9 Catechin Miramat
This is a multipurpose sheet which can absorb
formaldehyde and also having antibacterial and
deodorizing properties.
1.10 Catechin Cosmetics
The antioxidative potency and UV protecting functions
of tea catechins are widely utilized in manufacturing
cosmetics in Japan and South Korea. Green tea
polyphenols becomes one of the favourite ingredients
for cosmetic preparations. Kumar et al. (2012) reviewed
the availability of human data on their skin effects and
opined that the effects may be small but significant
and do meaningfully improve skin feel and appearance
with continued use. Tea catechins have protective
effects against UV damage and prevent pigment
colouration (Kuroda and Hara, 2004). Green tea
contains various natural ingredients that help retain
healthy and radiant skin. The ranges of products,
which contain either highly purified catechins or green
tea as an extract/powdered form, are available in the
market. Hair care products include shampoos and
conditioners, ultraviolet screens and colour protectants.
Cosmetics, which contain green tea, include soap,
moisturizer's perfumes, sunscreens and foundations.
The European and Asian market is emerging rapidly
as a consumer of nutraceuticals and cosmetics with
green tea used as part of ingredient list. Green tea skin
care aroma moisturizing face mask is also available in
the markets.
1.11 Catechin Jel
The oral cavity contains more than hundreds of
cariogenic and periodontopathic bacteria and their
presence may result in, not only oral infection, but
also systemic diseases, such as infective endocarditis
and aspiration pneumonia. Tea extracts have been
used as an additive to the toothpaste or gum for the
purpose of preventing dental caries. The application of
catechin gel inhibited the growth of the Actinomyces,
periodontopathic bacteria and Candida strains tested
(Tamura and Ochiai, 2012). Further, while reviewing
the research on the advantage and benefits of catechin,
they highlighted the possible use of catechin gel
against oral diseases, such as dental caries, periodontal
diseases and candidiasis (Tamura and Ochiai, 2012).
Tea polyphenols are anticarious in three ways: (1) they
inhibit the plaque forming enzyme, (2) they suppress
the growth of
Streptococcus mutants
and (3) they
solidify the enamel (Hara, 2001). EGCG also inhibits
the growth and the adherence of
Porphyromonas
gingivalis
, bacteria responsible for periodontal disease
(Sakanaka et al., 1996; Kakuda et al., 1994).
1.12 Catechin pet foods

good health, and to reduce faecal odour and caries
in cats and other pets. Catechin pet foods are
popular in Japan.
1.13 Kitchen Spray
Tea catechins are dissolved in ethanol/water and added
to a hand spray. Tea catechins could absorb amines
which are responsible for characteristics fishy smells in
kitchen (Kuroda and Hara, 2004). After cooking fish, a
spray of this liquid removes the fishy smell.
1.14 Catechin Eggs
In several clinical studies with human, it was reported
that the tea catechin lower cholesterol in the blood,
inhibit oxidation and protect against heart disease.
(Ghosh Hajra, 2006) This beneficial function has been
applied by fixing feed with tea catechins when used
