The present invention relates to new water

Example 1.--To 80 parts of a neutral or acid
soluble soaps, being compositions consisting of
soap 20 parts of triphenyl-dichloro-benzyl-phos- '
neutral or acid soapy washing agents and moth
phonium chloride are added, and the whole is
proo?ng agents having an a?lnity for W001, said ‘intimately mixed.
5 soaps being suitable for cleaning and rendering
moth proof Wool, feathers, hair and the like in
one and the same process.
- We mean by neutral washing agents, for in-
stance, the neutral alkali salts of palmitic, stearic
10 and oleic acids as contained in the usual soaps
and by acid washing agents, the alkyl esters of
sulfurized castor oil or of sulfurized oleic acid or
oleyl-methyl-amino-methane sulfonic acid or
oleyl-hydroxy—ethane-suiionic acid (sodium salt)
5 or similar washing agents resistant to acid reaction. We mean by moth proo?ng agents having
a?inity for W001 the salts of quaternary phos-

~
phosphonium bases can be used either alone or
mixed with another one, the quantity depending
on the e?icacy of selected compounds. 10 parts
of this special soap dissolved in 1,000 parts of 10
water are used for washing woolen material in
the customary manner at about 40 to 50° C. The
material treated in such a manner is cleaned and
moth-proofed at the same time.
Example 2.—To 80 parts of oleyl-methyl-ami- 1‘
no-ethane-sulfonic acid 20 parts of sodium-silico
?uoride are added, and the whole is intimately
phonium bases such as triphenyl-dichloro-benzyl-

used for simultaneously cleaning and moth proofing materials liable to attack by moths. The
speci?c moth proo?ng agent incorporated with
40 the soapy Component depends on the chemical
behavior Of Said soapy Component, which is more
fully described hereafter. Thus, when using as
moth-proo?ng agent the free selenic acid or selenious acid itself or acid or acid salts of hydro45 ?uoric acid or hydro-fluo-silicic acid or their soluble salts or suitable mixtures of the above agents,
a soapy component resistant to the acid reaction
is required, for example,‘ oleyl-methyl-aminoethane sulfonic acid, while the salts of quaternary
50 phosphonium bases may be combined with the
neutral alkali salts of palmitic, stearic, oleic acid
1 and the like.
The following c'zamples will illustrate our in- '
vention but without limiting it thereto.
55 parts are by weight.
'
of 10 parts of this special soap in 1,000 parts of 25
water will be cleaned and moth proofed at the
same time.
Example 3.-80 parts of oleyl-hydroxy-ethane
The new compositions are obtainable in a
_ known manner by incorporating into such neu3O tral or acid washing agents moth proo?ng agents
as above described.
The new compositions thus produced are colorless or slightly colored-in the dry state, and are
n, soluble in water. All these soaps, in the iorm
"'2 of lumps, powders, pastes or solutions, can be
\
- Instead of the triphenyl-dichloro-benzyl-phos- 5
phonium chloride also other salts of quaternary
The
sulfonic acid in the form of its sodium salt and
20 parts of dichloro-salicylic acid are intimately 30
mixed.
Wool treated in a solution of 20 parts of such a
soap in 1,000 parts of water is cleaned and ren
dered moth proof in this way.
Example 4.-—20 parts of bis-1.3-dichloro-ben- 35
zene-4-sulfo-1.3-phenylene-diamide are emulsi
?ed in 80 parts of the alkyl ester of sulfurized
castor oil.
Wool treated in a solution of 20 parts of such
a soap in 1,000 parts of water at 60° C'. is cleaned 40
and rendered moth proof at the same time.
A mixture of diiferent soaps may be applied,
and the process may be varied within wide limits
according to requirements. It will be, of course,‘
understood that when the new process is applied 45
to fur,‘care must be taken not to attack the skin.
This application is a divisional application of our
U, S. application Serial No. 535,564, which is now
Patent No. 2,082,188, issued June 1, 1937.
We claim:

sisting essentially of oleyl-methyl-amino-ethane
sulfonic acid in preponderating proportion and
sodium silico-?uoride, said composition being at
the most only slightly colored in the dry state, 55

simultaneously cleaning and rendering moth
proof wool, feathers, hair and like materials.
2. A moth-proo?ng detergent composition con
sisting essentially of the sodium salt of the oleyl
hydroxyethane sulfonic acid in prepondering pro
portion and potassium hydro?uoride, said com
position being at the most only slightly colored
in the dry state, being soluble in water, and be
10 ing adapted for simultaneously cleaning and
rendering moth-proof 'wool, feathers, hair and

3. A moth-proo?ng detergent composition con
sisting essentially of an acid soapy washing agent
in'preponderating proportion and of a water
soluble moth-proo?ng agent having an amnity
for W001 selected from the group consisting of
acid hydro?uoric acid salts, hydrosilico-?uoric
acid, hydro?uoro-titanic acid, boro-?uoro-acetic
acid, selenious acid, selenic acid, and salts of the
said acids, said composition being at the most
only slightly colored in the dry state, being sol
uble in water, and being adapted for simultane
ously cleaning and rendering mothiproof wool, 10
feathers, hair and like materials.
