I have now found that non-black wax emul- \
gen-containing substances which are not dye
stuffs and do not form gum-like products and
which are readily reducible by hydrogen at ordi
nary temperature but which do not oxidize to any
25 considerable extent‘ the constituents of the emul
sions under the conditions concerned. Suitable
substances of the said kind are, for example, per
oxidic compounds, such as hydrogen peroxide,

The emulsion thus obtained may be employed,

The said substances, when they are soluble in
water, are preferably added to the water em
ployed for, the preparation of the emulsion; they
may. however. be added to the fused wax before
vll) its emulsl?cation, especially when they are in
.
soluble in water. The amounts of the said addi
- ‘tional substances to be added are very small.
Generally speaking 10 grams or less per kilogram
of wax emulsion are sufficient; several per cent
45 may also be employed. The invention is not re
stricted to the addition ofspecial proportions.

containing substances are to be added according
to‘the present invention may be made up in the

Instead of sodium perborate, the same amount 35
of the alkali metal salt of a nitrated phthalic acid
may be employed whereby the same eifect is ob
