Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application: The present invention improves cleaning effectiveness and softening properties in the presence of quaternary ammonium softening compounds, anionic surfactants and nonionic surfactants. The present invention relates to a novel softening detergent liquid composition for use in washing fabrics, which contains an effective amount of alkyl glycoside to wash fabrics.

Prior Art: The use of various chemicals, particularly cationic quaternary ammonium compounds, as softeners for textiles is well known in the art. It is also well known to use such materials for their softening effect during washing operations, particularly in the rinse cycle of the washing process. This latter method is largely due to the fact that the quaternary ammonium compounds used hitherto, which are cationic, are not compatible with anionic detergents, which are one of the main detergents used in wash cycles. is necessary. Furthermore, cationic detergent compounds are relatively ineffective in the presence of nonionic detergents.

It is also well known that washed items tend to yellow or discolor when treated with the quaternary ammonium compounds.

Another disadvantage of using said cationic agents for washing fabrics is that they prevent the deposition of optical brighteners on the fabrics.
The objective is to reduce the optical brightening effect of detergent compositions containing such optical brighteners.

Yet another disadvantage of cationic quaternary ammonium antistatic softeners is that they interfere with the detergency of the detergent by reducing soil removal by the detergent, reducing its cleaning effectiveness. The presence of anionic detergents negates the fabric softening properties of cationic quaternary ammonium compounds.

Therefore, the quaternary ammonium compounds are combined with various compounds designed to counteract their disadvantageous cleaning properties, or instead of the quaternary ammonium softeners, other compounds are used to improve the cleaning effect. Softeners are used.

．． No. 094,118 and No. 0.106,692, the prior art also includes alkyl polyglycosylation, conventional nonionic surfactants and cationic fiber softening compounds, and Discloses a detergent composition that exhibits both softening and detergent properties. However, these patents specifically exclude anionic surfactants as being detrimental to the composition.

US patent! No. 4,014,808 contains an alkaline builder, a mixture of higher alkyl monoglycosylates and polyglycosides, a nonionic ethoxylate or anionically modified ethoxylate in acid form, and a flocculant to flocculate the soil into floating flocs, and optionally discloses an aqueous detergent composition for cleaning hard surfaces, such as floors, comprising a flotation agent that is sodium alkylaryl sulfonate.

However, none of the above prior art references show both cleaning effectiveness and softening properties in the presence of a main quaternary gold-containing i.e. quaternary ammonium softening compound, an anionic surfactant and a non-ionic surfactant. does not disclose a liquid detergent composition that simultaneously cleans and softens fabrics that includes an effective amount of an alkyl glycome to improve the properties of the fabric.

Problem to be Solved by the Invention: When an alkyl hoglycoside surfactant is added to a liquid softening detergent composition containing a cationic quaternary ammonium softening compound in a nonionic-anionic surfactant system, It has now been discovered that the cleaning power is increased, thereby increasing the softening properties of treated fabrics.

It is therefore a principal object of the present invention to provide a liquid detergent with improved cleaning effectiveness in the presence of cationic quaternary ammonium softening compounds.

Another object of the present invention is to contain an alkyl glycosylation compound, a quaternary ammonium softening compound, a nonionic surfactant and an anionic surfactant as the main four components, and simultaneously wash and soften the fabric during the washing process. It is an object of the present invention to provide a liquid detergent composition that has the following properties.

Yet another object of the invention is to provide a liquid detergent with improved detergent and softening properties due to the presence of an alkyl glycoside in a detergent composition comprising a mixture of anionic, nonionic and cationic surfactants. An object of the present invention is to provide a composition.

Other objects, advantages and novel features of the invention are set forth in part in the following description, and in part will be apparent to those skilled in the art based on examination of the following, or by practice of the invention. It seems likely that this will be achieved. The objects and advantages of the invention may be realized and attained by means of the instruments and combinations particularly pointed out in the appended claims.

SUMMARY OF THE INVENTION In accordance with the invention as embodied and outlined herein, in order to achieve the above and other objects, a liquid detergent composition of the invention for use in fabric washing comprises four main components: a quaternary ammonium softening compound in an aqueous carrier, an effective amount of an alkyl glycoside to improve cleaning efficacy and softening properties in the presence of anionic and nonionic surfactants; Also, a method according to the invention for simultaneously cleaning and softening fabrics without reducing brightener effectiveness and cleaning power comprises treating the fabrics with said composition during the wash cycle of the wash operation.

To explain in more detail, the present invention provides a sufficient amount of carbon to overcome the reduction in detergency caused by quaternary ammonium compounds.
1. Approximately 2 to 5 alkyl mono- or polyglycosides, approximately 2-8% by weight of softening compounds, approximately 8% nonionic surfactant
The present invention relates to a stable liquid softening detergent composition comprising ~25% by weight and about 1-12% by weight of an anionic surfactant in an aqueous carrier.

Alkyl glycosides act as softening agents and enhance fabric softening in the presence of cationic surfactants. It is conceivable that the alkyl glycoside 9 coats the surface of the fabric and/or changes the fabric structure to provide a softening effect. It is thought that alkyl glycosides disrupt hydrogen bonds and enhance the softening effect. Alkyl glycosides do not affect detergency and/or prevent brightener deposition, which is another problem with softening detergents.

The alkyl glycoside 9 used in the novel softening detergent of the present invention has 1 to 30 carbon atoms, preferably 8 to 1 carbon atoms.
5 and one hydrophilic group containing from 1 to about 10, preferably from about 1 to 3 sugar radicals. The alkyl glyconde is represented by the following formula: RO(R'O), Zn [wherein R(dCl-c3o alkyl radical,
(R10) is an ethoxy, propoxy or glyceryl group, X is a numerical value of O to 10, preferably 0, Z is a reducing sugar having 5 or 6 carbon atoms, and n is 1 to 10
The hydrophobic alkyl group is a saturated or unsaturated, branched or straight chain, preferably a saturated straight chain group having 1 to 30 carbon atoms, preferably 8 to 23 carbon atoms. It is the basis. Suitable alkyl polyglycosides include methyl, ethyl, propyl, octyl, nonyl, tecyl, undecyl, dodecyl, tridecyl, tetradecyl, hexateflu, heptadecyl, octadecyl and mixtures thereof, mono-, di-, tri-, and tetra-glycosides. Ntan lycoside.

Hexaglycoside, etc. The glycosylation unit may be glucose, galactose, mannose, lactose and/or fructose. The method for producing the glycoside is described in U.S. Pat. No. 3,598,865; No. 3,707.
, No. 535; No. 3,839,318; No. 3,772,
No. 269; No. 3,219,656.

All of these patents are incorporated herein by reference. Addition of alkyl glycosides to softening detergents improves the detergent's cleaning effectiveness.

The amount of glycoside should be sufficient to counteract the detergency loss due to the presence of the cationic quaternary ammonium softener in the softening detergent.

Therefore, the glycosyl-containing powder improves the detergency of the softening detergent and improves the detergency of the composition by approximately 1-30 M-Ik, preferably 2-30 M-Ik, of the composition.
It accounts for 25% by weight.

Addition of 5.3% ethylene oxide lowers the softening rating to 6.0. Omitting the quaternary ammonium compound and increasing the methyl glycoside to 6% increases the softening rating to 7.2.

The above results show that methyl glycosides have a softening effect on fabrics. Laboratory tests also showed that glycosides impart a whitening effect to liquid formulations.

However, in the absence of quat, static suppression is not achieved.

Softening detergents containing alkyl glycosides not only overcome the reduction in detergency caused by the presence of quaternary ammonium softeners, but also improve the detergency and softening properties of softening detergents! It was unexpectedly discovered that il was improved by one line.

This indicates that product 4 (Example 3), which contains only 2% methyl glycosides, is different from product 1, which contains no alkyl glycosides.

Furthermore, the formulations of the present invention are more effective than other surfactant and/or softener compositions currently on the market, as can be seen from the comparative results in Tables 1, 2, 3, and v. As such, it shows good cleaning and softening effects.
