Surface active compositions |
(57) A surface active composition which is either a liquid or dry powder, which comprises:
a) from 15 per cent by weight to 99 per cent by weight of an alcohol ethoxylate having
the formula R-O-(CH₂CH₂O)
n-H, wherein R is an alkyl group having from 8 to 18 carbon atoms or an alkylaryl group
having an alkyl moiety in the range of from 8 to 12 carbon atoms, and n represents
the average number of oxyethylene groups per molecule and is a number in the range
of from 1 to 12, b) from 1 per cent by weight to 80 per cent by weight of a salt of
an alcohol ethoxysulfate having the formula R′-O-(CH₂CH₂O)
x-SO₃M, wherein R′ is an alkyl group having from 8 to 18 carbon atoms or an alkylaryl
group having an alkyl moiety in the range of from 8 to 12 carbon atoms, M is a cation
selected from the group consisting of an alkali metal ion, an ammonium ion and mixtures
thereof, and x represents the average number of oxyethylene groups per molecule and
is a number in the range of from 1 to 12, and c) from 0.01 per cent by weight to 15
per cent by weight water, wherein components (a) and (b) comprise at least 85 per
cent by weight of components (a), (b) and (c) and if desired an adsorbent powder detergent
ingredient.
