COMPOSITIONS THEREFOR, OR PROCESSES OF PREPARING THE
COMPOSITIONS
Class Definition:
This class is an integral part of Class 252, as shown by the
position of the box identifying this class in the Class 252
schedule. As such, this class is subject to the Class
Definition and Notes of Class 252, except as noted in the
box.
(1) STATEMENT OF CLASS SUBJECT MATTER
This class includes the following subject matter, not
provided for elsewhere, when a utility set forth below is
either (a) claimed or (b) solely disclosed.
(A) CLEANING COMPOSITIONS FOR SOLID SURFACES which are
specialized and designed for, or peculiar to, use in cleaning
or removing foreign matter from solid surfaces.
(B) AUXILIARY COMPOSITIONS, PER SE, for perfecting the
cleaning compositions of this class or for perfecting a
cleaning process (e.g. rinse- or dryer-added fabric softener
compositions, etc.) for which there is no provision
elsewhere.
(C) COMPOSITIONS OF THIS CLASS DEFINED IN TERMS OF SPECIFIC
PHYSICAL STRUCTURE (E.G., TABLET, COATED PARTICLE, ETC.) -
The lines generally prevailing between the composition
classes and the article classes are applicable to Class 510
unless otherwise indicated, with the exception that Class 510
provides for a composition, per se, defined in terms of
specific structure, having a utility for Class 510.
(D) PACKAGES of compositions of this class, or other articles
which releasably enclose or support such compositions, for
which there is no provision elsewhere.
(E) PROCESSES OF PREPARING subject matter of A - D not
provided for elsewhere.
(2) CLASSIFICATION GUIDELINES FOR THIS CLASS
(A) In this class, the classification of a composition is
based on its primary utility as (a) a cleaning agent or (b)
an auxiliary agent for perfecting a cleaning composition or a
given stage of a cleaning process.
(1) Within category (a), above, the classification is based
on (i) the claimed or solely disclosed utility for cleaning a
specific substrate or removing a specific contaminant; or,
for all-purpose cleaning compositions, or (ii) the presence
of a specified perfecting component; (iii) the physical form
of the claimed composition; (iv) the particular process of
preparing the composition; and (v) the chemical nature of the
components of the composition.
(2) Within category (b) of section A, above, the
classification is based on (i) the claimed or solely
disclosed utility as a perfecting component for a cleaning
composition or as an auxiliary composition for cleaning, with
further placement according to criteria (ii), (iii), and (v)
of section A, (1), above.
(3) Within category (v) of section A (1), above, the chemical
structure of the components of a composition disclosed as
having a utility set forth in section A (1), above, is used
as the primary basis of classification. Processes of using
compositions or compounds, per se, and processes of making
the compositions, not provided for elsewhere, are classified
in the first appearing subclass providing for the particular
component being employed or prepared.
(B) The rule followed in classifying a patent having separate
claims to several species of a given ingredient which fall
into different subclasses is that the patent is placed as an
original in the first appearing subclass providing for the
claimed subject matter and cross-referenced to the
appropriate lower subclass(es). Where there are one or more
indents under the generic subclass and one of the claimed
species is not provided for specifically by any of these
indents the patent is placed as original in the generic
subclass, since this is the first appearing subclass
providing for said individually claimed species. In
classifying a patent containing Markush type claims (e.g.,
"group consisting of X and Y") and no species claims, the
original patent is placed in the first appearing subclass
providing for the species (members) in the Markush group. If,
in addition to the Markush group, there are species claims,
the first cited rule, governing a patent having separate
species claims, is followed. The same rules apply to subject
matter within the meaning of categories (i)-(iv) of section
A, 1, above, by analogy with the "species" concept.
(C) Patents claiming subject matter coming within the Special
Subclasses 101 through 107 have been classified on the basis
of the claimed or disclosed function and the chemical
structure of the active component (i.e., fragrance or aroma
enhancer), and include compositions which otherwise would
fall within subclasses 108 through 537 as originals.
(D) In determining the utility of a composition recited in
broad terms (e.g., "a cleaning composition comprising," "a
fabric softener composition comprising," etc.), use is made
of the specific utility recited in any nominal method-of-use
claims to determine placement of the patent within the
categories of (a)(i) or (b)(i) of section A, above (e.g., the
recitation of "a process of defluxing a printed circuit" or
"a process of softening a fabric in the rinse cycle of an
automatic washer" would place each patent in subclasses 175+
and 521+, respectively).
(E) Mere presence of a surfactant component is insufficient
for placement of a patent in subclasses 108 through 512 of
this class, since surface-active agents are used in minor
amounts as emulsifying, suspending, dispersing, etc., agents
in many other compositions, such as bleaches, fabric
softeners, etc. The placement of such a patent is determined
by the ultimate utility of the claimed composition.
(F) A patent claiming a cleaning or auxiliary composition
without specifying its physical form has been placed as an
original in the first subclass providing for the claimed
composition as if a structureless powder were recited in the
claims, and crossed into appropriate subclasses providing for
any other disclosed or exemplified physical forms (e.g.,
liquid, tablet, etc.).
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
(A) GENERAL CLASS LINES
(1) COMPOUND CLASSES
a. Where a patent claims a Class 510 utility in nominal
terminology only (e.g., "A process of producing a
biodegradable detergent compound") and there are no claims to
a Class 510 method of use or a true mixture, the original has
been placed with the compound claimed.
(b) Where a patent claims a composition wherein, in addition
to a compound, (i) another ingredient is recited, however
broadly, or (ii) proportions are recited, the original has
been placed in Class 510. Some examples of claims using broad
terminology and included herewith are: "A cleaning
composition comprising a surfactant of the formula," "with a
detergent builder," "A cleaning composition comprising 1 to
5% of compound X," etc.
(2) COMPOSITION CLASSES
The rules for determining Class placement of the Original
Reference (OR) for claimed chemical compositions are set
forth in the Class Definition of Class 252 in the section
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS, subsection
COMPOSITION CLASS SUPERIORITY, which includes a hierarchical
ORDER OF SUPERIORITY FOR COMPOSITION CLASSES.
(3) PROCESS OF USE CLASSES
The following general lines exist between Class 510 and other
classes providing for cleaning processes or containing
patents wherein the claims recite a process of cleaning a
solid substrate as provided for in that class.
(a) Where a patent claims a cleaning composition and a
nominal process of using the composition, the original has
been placed with the claimed composition. Some examples of
nominal terminology are: "applying the composition and
removing it {by rinsing, wiping, etc.}," "immersing the
article to be cleaned in a cleaning bath containing the
composition," etc.
(b) Where a cleaning composition, per se, is not claimed or
where the claimed cleaning process involves significant
process steps in using a claimed composition, the original
has been placed with the claimed cleaning process. Examples
of significant process steps include the use of a cleaning
bath or medium at a specified non-ambient temperature,
specified non-standard pretreatment and/or after-treatment
step in addition to contact with the cleaning composition,
etc.

GLOSSARY:
Note. The meaning to be given the various "art" terms
appearing in this class, which have not been included in the
GLOSSARY below, is the same as that generally accepted or in
common usage. However, certain terms employed in this class
(510), which are included below, have been assigned
definitions tailored to meet the needs of this class and
therefore these may be more restricted or less limited or
even altogether different from those in common usage. Their
use in any particular subclass is to be consistent with the
meaning in this Glossary. See the glossary in Class 532 for
definitions of other chemical terms used in this Class.
ANIONIC SUBSTITUENT
Denotes that portion of an organic compound which is
negatively charged in an aqueous solution at a neutral pH
(i.e., pH=7) and is attached to the portion of the molecule
of higher molecular weight by covalent bonding. Examples of
common anionic substituents include carboxyl, sulfate, or
phosphate monoester or sulfonate groups, as well as their
salts, including betaines.
CARBOXAMIDO
Denotes a substituent wherein a trivalent nitrogen atom is
single bonded to a carbonyl (-C(=O)-) group.

CATIONIC SUBSTITUENT
Denotes that portion of an organic compound which is
positively charged in an aqueous solution at a neutral pH
(i.e., pH=7) and is attached to the portion of the molecule
of higher molecular weight by covalent bonding. Examples of
common cationic substituents include primary, secondary, or
tertiary amino groups, as well as quaternary ammonium
substituents.
CORROSION (See METAL CORROSION)
CREAM
Denotes a thick, usually opaque, emulsion having little or no
tendency to flow.
GEL

embrittlement, tarnishing, or discoloration, usually by
chemical action.
NONIONIC COMPOUND
Denotes an organic compound devoid of cationic or anionic
substituents and thus lacking any ionic charge at a neutral
pH (i.e., pH=7).
ORGANIC
Denotes compounds containing carbon which are further
characterized by the presence in a molecule thereof of two
carbon atoms bonded together, or one atom of carbon bonded to
at least one atom of hydrogen or halogen, or one atom of
carbon bonded to at least one atom of nitrogen by a single or
double bond.

SURFACE-ACTIVE AGENT (Surfactant)
Denotes an organic compound which alters (usually reduces)
the surface tension of a liquid, thus facilitating cleaning.
Surface-active agents are commonly referred to as
surfactants, emulsifiers, wetting agents, or simply
detergents, as distinct from detergent compositions which
include additional components, such as detergency builders or
other cleaning auxiliaries. A surfactant molecule contains a
hydrophobic (water-repelling) portion which is frequently an
alkyl radical having a straight chain of eight or more
carbons, and a hydrophilic (water-attracting) portion. For
purposes of this class, the broad categories of surfactants
are based on the nature of the hydrophilic portion of the
molecule.
(1) Note. An anionic (anion-active) surfactant, referred to
in the schedule as "anionically substituted," includes a
hydrophilic portion which is most commonly a water-soluble
salt of a carboxylic or sulfonic acid, or of a long-chain
alcohol ester of sulfuric, phosphoric, or phosphonic acid
(e.g., sodium higher alkyl sulfonate, etc.).
(2) Note. A cationic (cation-active) surfactant includes a
hydrophilic portion which is a cation (i.e., positively
charged ion), such as an ammonium or quaternary ammonium
salt, having a long-chain alkyl substituent (e.g.,
higher-alkyl quaternary ammonium salts, etc.).
(3) Note. A nonionic surfactant includes a hydrophilic
portion which commonly is a poly(ethylene oxide) moiety
(i.e., polyether chain) attached to a hydrophobic portion
which may be nonpolar or have a lower degree of polarity than
the hydrophilic part, such as poly(propylene oxide), higher
alkyl, etc.
(4) Note. A zwitterionic, amphoteric, or ampholytic
surfactant includes both an anionic and a cationic portion
connected by a covalent bond, usually indirect (e.g.,
betaines, amino acids, etc.).
(5) Note. Semipolar nonionic surfactants include
water-soluble amine and phosphine oxides and sulfoxides.
(6) Note. Soap, for purposes of this class, is an alkali
metal, ammonium or organic base salt of an unsubstituted or
hydroxy-substituted, saturated or unsaturated higher fatty
acid, or of rosin (abietic) acid, or of mixtures of any of
these acids. These salts are water-soluble and are considered
to be anionic surfactants.
