Indian surfactants: Consolidation and
innovation – the needs of the hour
|
A
recently held conference on the Indian surfactants industry offered a
perspective on this important segment of the chemical industry; highlighting opportunities
and challenges facing the industry. While demand growth numbers look
attractive, especially to outsiders, these are as yet from a small base, and
serviced by a fragmented industrial base that is being challenged due
competition from within and from overseas. The feedstock base for the
industry has seen little development in the last few years and is unlikely to
for some more time, exposing the industry to supply chain disruptions and
volatilities.
Diverse applications
Surfactants
serve several industries. The most important of these – in an Indian context
– are home & personal care (HPC), textiles, agrochemicals, and paints
& coatings. Their role in these industries can be broadly divided into
two categories: cleaning – be it in a laundry detergent or a dishwashing
liquid; and emulsifying incompatible ingredients (oil & water, for
instance) – be it in a personal care formulation, in a can of paint or a
spray of pesticides.
By
virtue of their broad use in laundry detergents, in particular, the HPC
segment is the most important application of surfactants – both in India and
abroad. The ubiquitous laundry detergent powders, bars and liquids contain
one or more surfactants (along with other ingredients), as do personal care
products such as shampoos, conditioners, and beautifying creams &
lotions.
Anionics dominate; but nonionics seeing faster growth
Surfactants
can also be categorised on the basis of their chemistry into three main
categories: anionics, non-ionics and cationics (in descending order of the
volume in use). The most important of the anionics are the linear
alkylbenzene sulphonic acid (LABSA), derived from linear alkylbenzene (LAB),
while fatty alcohol ethoxylates (FAE) (derived from fatty alcohols – either
of petrochemical or oleochemical origin) are the most important of the
nonionics. The use of anionics, far exceeds that of nonionics, but the latter
are a faster growing category, due their gentler action, their compatibility
with a broader range of formulating ingredients compared to anionics and a
growing preference for ‘greener’ products that have natural origins.
LABSA – the workhorse surfactant
In
India, as in several other parts of the world, LABSA is the workhorse
surfactant, due several reasons: its low price (thanks to cheap crude oil);
its effectiveness under a broad range of washing conditions (hard water,
heavy soiling, hand washing etc.); and a long history of use. There are
perceptions that this is a harsh surfactant, and this has led to falling
growth rates in the developed world, but in India LABSA is here to stay for a
long time. It can be easy formulated into detergent powders and bars that
make the bulk of the Indian detergent market, and a vast processing network
exists to turn LAB into LABSA.
Alternatives
to LAB, in particular methyl ester sulphonates (MES) – a by-product of the
biodiesel industry – has been touted as an alternative surfactant, but
despite being around for more than a decade it has failed to make much of a
dent in the market. This has been attributed to several reasons including
restricted availability from a few producers (in contrast to LABSA),
difficulties in formulation and some issues of performance. The product did
find some acceptance, including in India, when oil prices soared, making
LABSA expensive, but the downward correction since has put paid to further
gains in market share.
Rising imports of LAB – a trend likely to stay
A
matter of concern is the domestic availability of LAB, the main feedstock for
LABSA. This is of petrochemical origin and is produced from two raw
materials: benzene and n-paraffins (NP) (in turn, derived from kerosene).
India
is currently severely deficient in LAB, and annual demand of about 620-kt is
met through domestic production of nearly 440-kt and imports of nearly
180-kt, mainly from the Middle East, China, Thailand and Egypt. The last
major LAB plant in India was set up more than a decade ago by Indian Oil
Corporation, and none of the incumbents have any plans to raise capacity
further to meet rising demand.
The
reasons for this are two-fold. While India is surplus in benzene (and exports
significant quantities of this aromatic), availability of NP from the
kerosene fraction of crude oil refineries is limited. A more important reason
is the commercial attractiveness of LAB projects given the significant
capacity build-up around: in Iran, China, Egypt and some countries of South
East Asia – all with very good cost positions.
It
is therefore likely that the trend of rising LAB imports to meet domestic
demand will continue for some more time to come. One factor that could change
things is the sustained campaign to replace kerosene as a cooking fuel in
rural and semi-rural parts of India, with LPG. This is curbing kerosene
demand and could force refiners to curb its production or alternatively look
to new markets for it. LAB could be one possibility. It should also be noted
that India will continue to build new crude oil refining capacity and these
will produce kerosene that will need to be gainfully utilised.
Nonionics – partnerships in South East Asia?
In
the nonionics segment, the HPC industries are expected to be strong growth
drivers, offering double-digit percentage growth rates for several years. FAE
are the largest product category here and the raw material picture is
comfortable. For one, the fatty alcohols needed (especially the C12-14 type)
are abundantly available – both from domestic sources as well as imports,
mainly from South East Asia. Indeed, India is a significant exporter of fatty
alcohols – despite having little or no access to vegetable oils & fats
that are its main source – and its exports have even been threatened with
antidumping duties in Europe.
One
way to get around the limitation of no linkage to vegetable oils & fats
is to have linkages with those businesses that do. The oleochemical business
is centred around South East Asia, in particular Indonesia, Malaysia and to a
limited extent Thailand and the Philippines. Companies in the business of
palm (and to a lesser extent coconut) plantations are keen to venture
downstream into value-added products from palm oil and coconut oil, and could
be potential partners. There have been some rumours of Indian companies
eyeing such linkages, but no deal has yet materialised. The benefits are
obvious: for the Indian oleochemical company it is an opportunity to tie-in
raw materials; for the plantation companies it opens up a fast-growing
market.
Market distortions
The
nonionics surfactants industry here is concerned with the trend amongst fatty
alcohol producers here to seek protection in the form of safeguard and
anti-dumping duties levied on imports from South East Asia. These duties have
distorted markets and even forced imports of downstream products including
finished surfactants, and unless corrected could impact the viability of
several businesses – mostly SMEs.
Ethylene oxide availability
There
have always been murmurs with respect to availability of the other raw
material for making nonionics – ethylene oxide (EO). The grouse of the
surfactants industry is that there is just one producer serving the merchant
markets – Reliance Industries Ltd. (the other producer, India Glycols Ltd.,
consumes all of its EO captively for derivatives) – but close examination
reveals there is presently adequate capacity with the petrochemical giant to
serve local needs.
But
it is hard to predict what Reliance’s plans are for the EO business, given
that it makes EO mainly for conversion to monoethylene glycol (MEG) – the
polyester intermediate for which it has an insatiable appetite. It would
hence be prudent for one or more of the petrochemical projects now in the
drawing board to set aside some of the EO produced for supply to the
surfactants industry. Remember, EO cannot be imported or even transported
long distances due its hazardous and explosive nature.
Focus on innovations
In
the industrial use of surfactants there is abundant scope for innovation.
Take paints & coatings, for a start. There is a clear trend in this
industry to move towards high-solids coatings and water-based systems and
these require effective surfactants. Leading companies in this space are now
even touting the ‘green’ credential of their paint systems (no odour, no
solvent, etc.) and are eyeing ‘greener’ surfactants that go with this image.
Surfactant producers are challenged to meet these needs – often without
getting an extra buck for their effort.
In
the agrochemicals industry, to cite another example, there is today a great
need to reduce sprayings and to use the minimum dosage of highly effective
actives. This requires that what gets sprayed is most effectively utilised to
tackle the pest at hand – needing innovations in surfactants and adjuvants. A
few Indian companies and several overseas players are making efforts in this
direction.
Transitioning from a commodity to speciality chemicals industry
The
Indian surfactants industry is still heavily dominated by commodity products
that have little or no differentiation from one supplier to another. Sales
hinge around being the cheapest and this is a slippery slope. Escalations in
cost of raw materials are often difficult to pass onto customers, leaving
surfactant producers with shrinking margins and depleted profits. Only a
handful of producers here have a scale that can be described as competitive
and even fewer have the credentials to serve markets beyond India. Both of
this will need to change if the industry is to be on a sustainable growth
path and not be driven to extinction by suppliers from overseas who have
forward and backward linkages that make for an overall healthy business.
Consolidation
is needed in this fragmented space and needs to be complimented with
continuous innovation!
