Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a cleaning agent that lathers well and gives a smooth and slippery foam feel when cleaning, and also gives a soft and moist feel to the object being cleaned when finished. Regarding the composition.

Conventional detergent compositions used for washing clothes or hair, etc., contain anionic surfactants as the main ingredient, and their main purpose is only to remove stains from the object to be washed. There is a problem that clothes, hair, etc. of people become sticky and dry. For this reason, the functions of cleaning compositions are required not only to have simple cleaning properties and foaming properties, but also to provide a soft, silky feel and a moist finish to the objects to be cleaned after cleaning. Regarding the foam during cleaning, it is desirable that the foam be not only fine-grained but also smooth and slippery.

Therefore, conventionally, cationic surfactants have been added to detergent compositions to improve the finishing performance of the detergent compositions.

However, when a cationic surfactant is blended into a cleaning composition, although the softness and moist feeling of the finished product are improved, it is difficult to say that the finishing performance is sufficient. When a cationic surfactant is blended into a cleaning composition, it has the disadvantage that foaming during cleaning is significantly reduced and at the same time, the cleaning power is deteriorated.

Furthermore, conventionally, cobo IJ? of dimethyldiallylammonium halide and acrylamide, which has excellent film-forming properties, has been used. -C
MERQUAT 550 (manufactured by Aru') Co., Ltd.) has been added to shampoos to enhance the conditioning effect. The effect of suppressing hair squeaking during rinsing is insufficient. Also, when washing hair, it gives a very rich lather and creamy feel, but it does not give a smooth and smooth foam feel.

The present invention has been made in view of the above circumstances, and provides a cleaning composition that lathers sufficiently during cleaning, gives a smooth and slippery foam feel, and gives a soft and moist feel to the object to be cleaned when finished. The purpose is to provide.

As a result of intensive studies to achieve the above object, the present inventors have found that a copolymer of dimethyldiallylammonium halide and acryloamide, etc. with the following general formula CI) (However, in the formula, R1 and R2 are each a group selected from a hydrogen atom, an alkyl group having 1 to 3 carbon atoms, and a phenyl group, R3 and R4 are each an alkyl group having 1 to 18 carbon atoms or a hydrogen atom, and ye is an anion.
s and t are each O or 1, and s+t=1, and m
is m≧1, and m and n each represent the molecular weight of the compound as 1.
This is a number from 0,000 to 1,500,000. ) By using the cationic polymer substance shown in ) and a lanolin derivative in combination, especially by using the same components together at a weight ratio of 115 to 2/1, these same components act synergistically, and the anion Even when a surfactant is used as the main ingredient, the foam quality, feel of use, and finishing performance can be improved without impairing the foaming and cleaning power, which are the advantages of anionic surfactants.
A detergent composition that foams very richly during washing, gives a smooth and smooth foam feel, and has excellent finishing performance, giving a soft and moist feel to items to be washed such as clothes and hair when finished. The present inventors have discovered that the present invention is possible.

Accordingly, the present invention provides a cleaning composition comprising a cationic polymeric substance of the above formula (I) and a lanolin derivative.

The present invention will be explained in more detail below.

The first essential component of the cleaning composition of the present invention is a cationic polymeric substance represented by the following general formula (I).

However, in the above formula (I), substituents R1 and R2 may be the same or different, but are an alkyl group having 1 to 3 carbon atoms, a phenyl group, or a water atom, and R3 and R4 may be the same or different. Although they may be different, the number of carbon atoms is 1 to 1
8. Preferably it is an alkyl group of 1 to 4 or a hydrogen atom. In the formula, 761 represents an anion, such as a halogen ion such as chlorine or bromine, an inorganic acid residue such as sulfuric acid or nitric acid, or an organic acid residue such as methyl sulfuric acid or hydroxycarboxylic acid. Furthermore, s and t are each 0 or 1,
and s+t==1, and m is m≧1 and m
, n are numbers that make the molecular weight of the compound 10,000 to 1,500,000, respectively.

That is, as a cationic polymer substance, s in formula (I)
=1 and 1=0 or S=O and 1=0 (II) below,
A copolymer of a dialkyl diallylammonium salt having a structural formula represented by the formula (nl) is used.

-, one or more of them can be used; specifically, the following formulas (■') and (■') (where R1, R'', R', R', Ye, m,
n is the same as above. ) In the present invention, a copolymer having the above structure (however,
In the formula, R1 and R2 are hydrogen atoms or methyl groups, Xo is a halogen ion, and m and n are numbers that make the molecular weight of the compound from 10,000 to 1,500,000. ) copolymer of dimethyldiallylammonium halide and acryloamide, such as MERQUAT 550 manufactured by Merck & Co.
etc. are preferably used.

Further, the lanolin derivative which is the second essential component of the present invention is not particularly limited, but it is preferable to use a cationic quaternary ammonium salt of lanolin represented by the following general formula (IV).

However, in the above formula, R5 is a lanolin residue, an amide of lanolin fatty acid, or a phenyl lanolin group, and RG
, R? and R8, which may be the same or different, are an alkyl group having 1 to 10 carbon atoms, especially 1 to 4 carbon atoms, or a hydrogen atom, and Q is a number of 1 to 8, especially 2 to 5.

Moreover, Ze represents an anion residue, and is an inorganic acid residue or an organic acid residue having a halogen ion or an alkyl group having 0 to 5 carbon atoms.

Among the lanolin derivatives represented by the above formula (rV), in particular, R5 is a lanolin fatty acid residue, R6 and R7R11 are each a methyl group or an ethyl group, Q is a number from 2 to 5, and we is methyl sulfate. or ethyl sulfate group, such as lanolin ethyl sulfate fatty acid aminopropylethyldimethylammonium (cation LQ
, manufactured by Sanyo Chemical Co., Ltd.), etc. are preferably used.

In the cleaning composition of the present invention, the cationic polymeric substance of formula (I) as the first component and the lanolin derivative as the second component are preferably blended in a weight ratio of 175 to 2/1. . In addition, although the blending amounts of both components are variously selected, the total blending amount of both components is 0.3 to 5% of the total (weight%, the same applies hereinafter), and in particular, the cationic polymer substance is 0.1 to 5% of the total. 3%
The lanolin derivative is preferably blended in an amount of 0.5 to 4% of the total amount. If the blending ratio of both components deviates from the above ratio, especially if the amount of the first component dialkyl ammonium salt is too large, it may not be possible to give the object to be cleaned an appropriate softness and moist feel during finishing. Furthermore, if the amount of the lanolin derivative as the second component is too large, the foaming of the detergent composition based on an anionic surfactant may be reduced, and the smooth and slippery properties of the foam may not be felt. When finished, the item to be cleaned may be sticky and not have a light texture.

In addition to the above-mentioned essential components, the cleaning composition of the present invention may contain appropriate components depending on the type of composition and purpose of use.
In particular, it is preferable to incorporate an anionic surfactant as the main ingredient. The composition of the present invention foams well, gives a smooth foam feel, and has excellent finishing performance even when an anionic surfactant is used as the main ingredient.

In this case, various anionic surfactants can be selected, such as amino acid surfactants, alkyl sulfates, and paraffin sulfonates, among which polyoxyethylene alkyl ether sulfates and alpha olefin sulfonates are preferably used. , its amount is usually 5 to 3 of the total composition.
It is 0%.

Furthermore, as other optional ingredients, various surfactants such as nonionic surfactants, amphoteric surfactants, and mono-long chain alkyl quaternary ammonium salts, which are commonly used ingredients in cleaning compositions, binders, ultraviolet absorbers, and preservatives are included. , a bactericidal agent, an emulsifying agent, an antidandruff agent, an antioxidant, a tonic agent, a pigment, a fragrance, etc., or two or more of them can be blended.

As explained above, the cleaning composition of the present invention foams well during cleaning, gives a smooth and slippery foam feel,
Moreover, when finished, it gives a soft and moist feel to the object to be cleaned, and has good cleaning power as well as excellent usability and finishing performance, and fully meets the demands of modern consumers.
