This invention relates to improved abrasive
may be pure sulfates or they may contain, as
compositions, more particularly it relates to im-
they commercially do, small portions of sulfonic
proved dry buffing compositions, more particularly it relates to dry buf?ng compositions con-
acids or mixtures of the same. They may be
saturated or unsaturated, or bridged, by a non
taining an amine salt of a sulfated higher ali-
carbon atom such as an oxygen group and may 01

contain from eight to twenty-four carbon atoms.
to a dry buiilng composition containing a tertiary amine salt of a higher alkyl sulfate and a
, higher aliphatic alcohol,

This invention has asan object the prepara-
It has been found that if a mixture of about
one part of an amine salt of a higher alkyl sul
fate and about two parts of a‘higher aliphatic
alcohol are added in amounts of about 2 to 4% by 10
tion of an improved buffing composition. A further object is the production of boiling compositions for the polishing of metals. A still further
object is the production of a bu?ing composition
15 which facilitates the cutting and polishing of
metals. Another object is the production of a
bu?‘ing composition for the polishing of metals
which eliminates scratches. A further object is
the production of a dry bu?ing composition. An
20 additional object is the production of a bu?ing
composition which may be easily removed from
the polished surface by washing. Other objects
will appear hereinafter,
weight to bu?ing compositions during their prep~
aration, the resulting buffing compositions are
greatly improved. Thus, they have the improved
working characteristics of reducing scratches on
the surfaces of the materials treated and of be- 15
ing washed from the surface with facility. The
amine salts and the higher aliphatic alcohol may
be added to the buffing composition during the
preparation of the same at various stages. Thus,
the fatty or waxy ingredients of the buffing com- 20
position may be ?rst lique?ed, the amine salts of
the higher alkyl sulfates and the higher alcohols
added, and then the abrasives added and inti

mately mixed therewith, The abrasives can be
added to a mixture of the amine salts of the 25
higher alkyl sulfates and higher alcohols, and the ,
latter added to a liqui?ecl mixture of the binders.
or the abrasive material may be first incorpo~
rated in the lique?ed binder and then the amine 30

These objects are accomplished by the following invention which comprises the incorporation
of an organic amine salt of a sulfated higher aliphatic alcohol into a buffing composition. More
particularly they are accomplished by incorpo30 rating a pentavalent nitrogen salt of the formula:

to various commercial forms; preferably they are
cast into bars.

Buffing compositions, which are known also as
rough or metal polishes, in general consists of a
mixture of abinder and an abrasive The binders

carbocyclic or heterocyclic ring or one end of a

at least eight Carbon atoms which may be fur45 ther substituted by hydroxyl, alkoxy or halogen

Particularly, they are accomplished by' incorporating a. tertiary amine salt of a higher alkyl
sulfate and a higher aliphatic alcohol into a

The sulfated alcohols
As a general rule, fatty or
waxy materials of animal origin are preferred
Petrolatum, when admixed with animal waxes,
has special utility.
45
The common types of abrasives used in buffing
compositions are tripoli, rouge, (iron oxide), lime,
magnesium oxide, mixtures of lime and magne
sium oxide, alumina, carborundum, chromium
oxide, etc. Other abrasives may be used for spe- 50
cial purposes where a soft polish is desired, such
as technical aluminum silicate.
Metal and other surfaces are bu?ed or polished
by the application of the. buffing composition in
bar form to a bumng wheel.
There are two gen- 65
2
2,119,159
eral types of buffing operations in connection
with the treatment of metal surfaces. A cutting
operation in general de?nes a relatively heavy
polish which is imparted by the action of a rap
idly revolving laminated cotton cloth polishing
Wheel on the metal object. In the cutting oper
ation a fairly coarse grade of abrasive is used.
A coloring operation in general is a light high
polish imparted by a cloth polishing wheel to a
10 metal object. The polish is likewise obtained
by the action of a rapidly revolving laminated
cotton cloth polishing wheel. The bar of rouge
is applied intermittently to the revolving polishing
Wheel. In general, a very fine grade of an abra
15 sive is used in the coloring operation. The color
ing operation is so-called because of the fact that
the coloring of the metal surface is brought up as
a result of the bu?ing operation.
After polishing, the metal and other surfaces
20 are washed free of the bu?'lng compositions. The
surfaces may be treated in various ways after
having been polished. Thus, they may be coated
with lacquers, enamels, paints, and other coating
compositions, or electro-plated, being .very recep
25 tive to such treatment.

in the fact that the improved buffing composi
tions of this invention reduce or eliminate
scratching. Another advantage resides in the
feature that both cutting and coloring operations 40
may be combined into a single operation with a
resultant substantial saving ' in operating cost.
A still further advantage resides in the fact that
the lubricating properties of the compositions are
improved. Thus, cheap grades of abrasives can 45
be used in place of the ?ner and more expensive
ones without decreasing the quality and finish of
the bu?ed metal. This invention possesses the
further advantage that the compositions may be
quickly and economically made wtihout any ne
cessity of ageing. Ageing, however, in some in
stances produces very beneflcial results. In the
preparation of bu?lng compositions in the past it

While fairly good results can be obtained with
any amine salt of a higher sulfated alcohol, the
tertiary amine salts of alcohols having from
twelve to eighteen carbon atoms give excellent
75 results. In the preferred embodiment of this in
has been necessary to age the prepared compo
sitions for approximately four months before the 55
maximum/ polishing property is developed. The
compositions of the present invention based upon
the addition of the higher alcohols and amine
salts of alkyl sulfates show maximum polishing
properties immediately after they have been pre
pared and no ageing is necessary.
Previous buif
ing compositions commonly show a crystalline
fracture while the compositions of this invention
present an amorphous surface on fracture. This
invention has the still further advantage that the 65
buffing compositions may be used to polish all
types of metal surfaces such as the noble metals,
brass, bronze, nickel alloys such as Monel metal,
stainless steel and plated metals of all kinds as
well asv non-metallic surfaces, with excellent re 70
sults.
