Alpha
olefin sulphonate
(AOS)
Godrej
Alfodet L46 is the sodium salt
of alpha olefin sulphonate (SAOS),
commonly known as AOS. Alfodet
L46 is a detergent active of the
anionic class. It is manufactured
by continuous sulphonation of
high-quality ethylene-based alpha
olefins with sulphur trioxide
in a specially-designed modern
'Ballestra' continuous thin-film
sulphonation reactor, followed
by neutralisation and hydrolysis.
Alfodet
L46 is an extremely light coloured
liquid, thanks to efficient sulphonation,
with low inorganic salt and un-sulphonated
matter. No bleaching of the neutralised
AOS is done after hydrolysis,
ensuring that all supplies of
Alfodet L46 are safe sultones
within tolerable limits.
AOS
is an effective emulsifier and
has excellent foaming characteristics.
Its resistance to water hardness
and other metallic ions is very
good, and it is stable over a
wide pH range. It
is superior to conventional detergent
actives with regard to bio-degradability,
mildness to skin, cold-water solubility,
rinsability, flash foaming, and
detergency in hard water.
AOS
is compatible with other surfactants
like linear alkyl benzene sulphonate
(LABS) and SLS, including soap.
AOS helps to overcome the sting
caused by conventional detergent
actives. A combination of LABS
and AOS in certain proportions
can yield synergistic detergent
action, which can result in improved
performance of a given total active
or reduced cost for a given performance.
Alfodet
L46 is suitable as an active for
general detergent products such
as detergent cakes and powders,
toilet and laundry soaps, liquid
detergents for fine fabrics, dish-
and floor-washing liquid, woolen-
and carpet-washing applications,
scourers and shampoos, bubble
baths and shower gels.
AOS
liquid can replace LABS in detergent
powder by incorporation at a 1.5
per cent active level or higher,
depending on moisture level adjustment
in the final product.
