CONCLUSION
Oral care market is highly c o m p e t i t i v e and d y n a m i c . T o o t h p a s t e is the m o s t d o m i n a n t oral
care product. T h e r e are t w o major e s t a b l i s h e d brands and f e w small brands in Sri Lankan
scenario.
There are lot o f market research studies c o n d u c t e d
on the c o n s u m e r profile, oral
care
p e r c e p t i o n s and habits, herbal and non herbal toothpaste etc. T h e s o c i o e c o n o m i c a s p e c t s like
dental e d u c a t i o n , dental health facilities in the country are r e a s o n a b l y g o o d .
The s c i e n t i f i c r e s e a r c h e s d o n e o n toothpaste f o r m u l a t i o n are abundant and m o d e r n t o o t h p a s t e
formulation is substantiated by lot o f technical k n o w l e d g e . T h e r e is a reason to add e a c h and
e v e r y raw material
into the formulation and e a c h o f the i n g r e d i e n t s are r e s p o n s i b l e
for
specific attributes.
In s u c h a s c e n a r i o it is o n l y by a c o h e s i v e approach that o n e c o u l d d e v e l o p a n e w t o o t h p a s t e
thai c o u l d potentially capture a c c e p t a n c e o f the v a l u e s e e k i n g c o n s u m e r s . C O R D as illustrated
in f i g 4.1 is an approach that attempts to orientate the w h o l e d e v e l o p m e n t p r o c e s s w i t h a
customer
focus.
It tries to isolate the distinctive
technical
parameters and m e a s u r e
the
importance o f the s a m e in the m i n d o f the c o n s u m e r . T h e n the important parameters are
idemi lied and m a n i p u l a t e d in the laboratory to c o m e up w i t h an o p t i m u m product.

T h e a b o v e approach
is f o l l o w e d
in d e v e l o p i n g die n e w t o o t h p a s t e and the o u t c o m e
is
p r o m i s i n g . T h e s u r v e y 1 has c o m p a r e d t w o local l e a d i n g brands w i t h an international brand.
T h i s is an attempt to b e n c h mark the local toothpaste brands and then to arrive at the
s i g n i f i c a n c e o f different technical parameters in relation to c o n s u m e r n e e d s .
It w a s this first s u r v e y that m a d e clear that the local toothpaste c o n s u m e r is flavor driven as
o p p o s e d to international c o n s u m e r w h o is benefit driven. It w a s o n l y in parameter related to
flavor that there w a s a significant difference a m o n g three brands. T h i s led to the s e c o n d
s u r v e y w h e r e three different flavors are tested and statistically a n a l y z e d and arrived at the best
flavor.
O n c e the product and the flavors w e r e fixed the approach is to e c o n o m i z e .
