Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to liquid laundry detergent compositions for use in household and industrial laundry.

[Prior Art] Such liquid detergents are mostly made of a mixture of anionic surfactants and nonionic surfactants and do not contain builders, so they are not effective against fatty stains. The cleaning power is only moderate, despite the high content of surfactants (approximately 40%); for a good cleaning effect on protein-containing soils, the inclusion of enzymes in the formulation is necessary. It is also necessary.

Attempts have also been made to include softeners in liquid detergent compositions to eliminate the need for post-treatment with softener solutions or dispersions. However, conventional softeners tend to be immiscible with the anionic surfactants present, so the composition does not remain as a stable solution but separates into two phases. If phase separation occurs, the composition must be shaken before each use, making accurate dosage measurements unreliable.

For this reason, liquid detergent compositions containing softeners have hitherto been produced only on the basis of nonionic surfactants, which have inadequate detergency.

[Problem to be solved by Hatsube] It is possible to produce stable liquid detergent compositions based on anionic surfactants having excellent detergency and containing selected softeners. It was discovered that something could be done.

Accordingly, the present invention provides stable liquid detergent compositions that are based on one or more anionic surfactants and that include a softener that is the product of acylation and quaternization of polyalkylene polyamines. That's true.

SUMMARY OF THE INVENTION Preferred softeners have the formula (wherein each R1 is independently an alkyl having 12 to 18 carbon atoms or an alkenyl having 12 to 18 carbon atoms, each n is independently 2 or 3, and R2 is 1 to 4
alkyl with 1 to 4 carbon atoms, hydroxyalkyl with 1 to 4 carbon atoms or hydroxyalkyl with 1 to 4 carbon atoms etherified with 1 to 10 ethylene oxide groups, and R1 is 1 to 4 alkyl or benzyl having 4 carbon atoms, X- is a halide, methyl sulfate or ethyl sulfate anion).

Preferred liquid detergents according to the invention contain (A) 1-15%, preferably 3-10% of the formula (
1); (B) 0 to 25%, preferably 4 to 20%, of a partially carboxymethylated or carboxyethylated ethylene oxide adduct of an aliphatic alcohol or alkylphenol; and (C) 5 ~30%, preferably 10~
(0) 2-20%, preferably 5-15% of one or more other anionic surfactants.

All percentages represent weight relative to the total weight of the composition including water. Preferably, active ingredients (A) to (0)
are 20 to 50% of each other, preferably 30% of the total composition amount.
~50%.

The composition also contains sufficient alkyl to neutralize the anionic component. Additionally, the composition contains a nonionic surfactant, a sequestering agent, a MW
Other conventional ingredients such as I agents, enzymes and optical brighteners may be included.

Softeners in (1) can be prepared in a conventional manner by reacting dialkylene triamines with fatty acids or functional derivatives thereof, followed by alkylation and quaternization with alkyl, hydroxyalkyl or benzyl derivatives. can. Preferred softeners contain at least one hydroxyalkyl group, preferably a β-hydroxyethyl group that can be etherified with an ethylene oxide group (preferably 1 to 5 EO groups) and at least one unsaturated fatty acid residue. groups, such as oleyl groups, preferably
The radicals R1 are both the same or the same average mixture of radicals, for example a mixture of 85% oleyl and 15% stearyl groups.

Component (B) preferably has the formula %(), where R is the residue of an aliphatic alcohol having 8 to 22 carbon atoms or an alkylphenol having 10 to 24 carbon atoms; A is a methylene or ethylene group, m is a number from 1 to 20, and X is an average value from 0.1 to 1) The compound of formula (11) is known, but or can be prepared by conventional methods from available starting materials. The most preferred product 4 (B) is obtained by reacting synthetic lauryl alcohol (having 12 to 15 carbon atoms) with 4 to 5 moles of ethylene oxide followed by reaction with 0.8 moles of chloroacetic acid. It is a compound. These compounds are usually their alkali metal salts,
Preferably it is used in the form of sodium salt.

The fatty acids of component (C) are preferably saturated or unsaturated carboxylic acids having 12 to 18 carbon atoms. These fatty acids, such as coconut oil fatty acids or oleic acid, are added neat and converted to the salt form by adding an alkali such as NaOH5K OH or an organic base such as triethanolamine.

The anionic surfactant of component (D) contains (a) fatty acid,
VA# of fatty acid esters and fatty acid amides! i salts and sulfonates, (b) linear or branched alkyl Km salts and sulfonates having 5 to 10 carbon atoms, (C) sulfated ethoxylated compounds, (d) polycarboxylic acids. ester sulfates, and (e) alkylbenzene sulfonates of 5 to 18 and alkyl and dialkylnaphthalene sulfonates having 1 to 4 carbon atoms.

These compounds can be added in acid form and converted to their salt form by adding an alkali.

Nonionic surfactants that may be present include ethylene oxide (EO)/propylene oxide (po) block copolymers (Pluronic
s) ), EO or po, preferably EO addition products to aliphatic alcohols, aliphatic amines, fatty acids, fatty acid alkanolamides and alkylphenols. Such nonionic surfactants are conventional and commercially available.

Drotropic compounds that can be present include, for example, urea, dicyandiamide and its derivatives, alcohols, water-soluble glycols, glycol ethers and esters and alkylbenzene sulfonates having 1 to 4 carbon atoms, up to 100'' There are some substances that do not show a cloud point in distilled water. Such compounds act to prevent phase separation, ie to stabilize the liquid composition.

Sequestering agents include citric acid, nitrilotriacetic acid and other complex formers. A buffer can be used to stabilize the pH of the cleaning solution in the neutral or alkaline range. Buffer materials include sodium bicarbonate, lithium carbonate, and sodium silicate.

[Action] By selecting these additive components and optionally using enzymes and optical brighteners, the cleaning effect of the liquid detergent can be adjusted depending on the desired field of use. Detergent compositions are primarily useful as household laundry detergents.

They not only exhibit good cleaning power but also impart a soft feel to washed cotton products. Phosphate-free is ecologically acceptable.

When used in combination with optical brighteners, they do not cause quenching of the brighteners, resulting in acceptable whiteness ratings. The liquid composition is stable and does not separate into two phases during storage.

The following examples illustrate the invention, but all.

The percentages are weight percentages based on the total acid group.

[Examples] Examples 1 to 7 In the following examples, component (A) has the formula (wherein R1
is a mixture of 85% oleyl groups and 15% stearyl groups), and component CB) is a mixture of 2RO
