Special rules of classification within this group

Each relevant compound / composition is classified according to the rules in the most appropriate place.

When classifying in the mixture groups of this subclass, any individual ingredient of a composition which is not identified by such classification, and which itself is determined to be novel and non-obvious, must also be classified in groups C11D 1/00-C11D 9/00. The individual ingredient can be either a single substance or a composition in itself.

Any ingredient of a composition which is not identified by the above classification, and which is considered to represent information of interest for search, may also be classified in groups C11D 1/00-C11D 9/00.

In groups C11D 1/02-C11D 1/94, C11D 3/02-C11D 3/39, C11D 7/02-C11D 7/46 and C11D 9/06-C11D 9/42, in the absence of an indication to the contrary, classification is made in the last appropriate place.

To decide whether a composition/compound is classified in C11D 3/00 or in C11D 7/00 the whole document is taken into account to find out if surfactants are present or not.

Documents classified in the mixture groups C11D 1/37, C11D 1/645 to C11D 1/655, C11D 1/825 to C11D 1/86, C11D 1/94 to C11D1/94D, C11D 10/04 to C11D 10/047 are indexed using Indexing Codes from C11D 1/00 to C11D 1/92 to provide information on the individual surfactant.

Compositions comprising solvent mixtures or a list of alternatives are classified in C11D 3/43 or C11D 7/50 and the single components may be classified as Indexing Codes from C11D 3/00 or C11D 7/00.

For classes C11D 3/2003, C11D 3/2006, C11D 3/2041, C11D 3/34, C11D 3/3905 and C11D 3/3907 in case of mixtures or a list of alternatives, Indexing Codes of C11D 3/2003, C11D 3/34, C11D 3/3905 are used for classifying the individual compounds.

Polymers are only classified in the top group C11D 3/37 in rare cases; dependent claims, examples and description should be taken into account and then the specific ones should be classified.

e.g. in claim 1 a polymer is claimed, in the description and dependent claims polyacrylate and carboxymethylcellulose are disclosed, the polymer is therefore classified in C11D 3/3757 and C11D 3/225.

The same is applied to per compounds and bleaching compounds in C11D 3/39 and C11D 3/395.

Carboxylic acid mixtures or alternatives are classified in C11D 3/2075; if specific acids are claimed they can be classified in the specific groups.

Block copolymers such as EOPO, Pluronics being surfactants are classified in C11D 1/008; if they are not used as surfactant, they are classified in C11D 3/3707.

In C11D 3/0005 the compounds / compositions are characterised by their effect or properties. Documents classified therein are also classified in other groups of C11D according to the chemical nature of the compounds as such.

In compositions comprising e.g. an unspecified surfactant and carbonates, only the carbonates are classified; i.e. in C11D 3/10.

In compositions comprising e.g. ethoxylated alcohol surfactant and carbonates, both, the specific surfactant and the carbonates are classified, i.e. in C11D 1/72 and C11D 3/10.

Polymers, enzymes, percompounds, bleaching agents, dyes, brightening agent and disinfecting, antibacterial, microbicidal agents in compositions without surfactants are classified in C11D 3/00.

Glossary of terms
In this subclass/group, the following terms (or expressions) are used with the meaning indicated:
Amphoteric surfactant
Amphoteric surfactants contain both acidic and basic groups in their molecule, and can act as cationic or anionic detergents, depending on the pH of the solution, or as both cation and anion. Betains are included.
Anionic surfactant
Anionic surfactants have a negatively-charged surface-active ion. An example is sodium alkylbenzene sulfonate.
Cationic surfactant
Cationic surfactants may have a positively-charged cation; typical are the quaternary ammonium salts; they may also be amides or amines.
Compounding ingredients
The non-surface-active ingredients in a detergent composition, e.g. builder, water-softening agents, solvent.
Detergents
Detergents are basically any cleaning materials. Such materials may or may not contain surfactants. The term "synthetic detergent" is also used as a synonym for "surfactant" (excluding soaps, which are not considered synthetic), which is a compound, or a mixtures of compounds, whose molecules have two distinct regions – one that is hydrophilic and has an affinity for water, and another that is hydrophobic, with little (if any) affinity for water. These compounds can aid in the solubilisation of hydrophobic compounds in water. See examples below of particular types of surfactant (detergent).
Nonionic surfactant
Nonionic surfactants are synthetic surface active agents which are such that the molecules do not ionise in aqueous solution. Typical are ethoxylated fatty alcohols, amine oxides. .
Resin soap
A yellow soap containing resin, used for bleaching. It is made by adding a certain quantity of resin (rosin or colophony), as much as 50 % and more of the fat employed, to the mass in the soap boiler towards the end of the process.
Syndet bars
Piece of hard soap made from synthetic surfactants.
Soaps
Soaps have the same properties as those mentioned above for surfactants, but in general soaps are not considered as synthetic detergents. Soap is a particular type of surfactant derived from oils and fats, and is created through the saponification process whereby the ester linkage in a vegetable oil or fat is hydrolytically cleaved using an alkali or (NaOH or KOH) or ammonia or amine yielding glycerol and crude soap.Soaps usually consist of the alkaline salts of fatty acids such as palmitic, stearic or oleic acids. Soft soaps contain the potassium salts, whereas the sodium salts are hard soaps. Soaps are examples of anionic surfactants.
Surface-active compounds/agents (surfactants)
Substances which have the effect of reducing the surface tension of a solvent, an example being a detergent/surfactant or soap dissolved in water. These substances, also known as wetting agents, contain a combination of polar (hydrophilic) and non-polar (hydrophobic) parts which serve to bind oil and water together. They locate at the phase boundary between the water phase and the organic phase, or if there is no room there, they will congregate together and form micelles.Both synthetic detergents and soaps are surfactants.
Surfactants
