A dishwashing liquid detergent composition comprising a surfactant mixture composed of alkyl sulphate, alkyl ether sulphate, alkane or alkene sulphonate and ethoxylated nonionic surfactants, the alkyl sulphate being present in the form of its magnesium salt. The combination of the ethoxylated nonionic and alkyl sulphate surfactants provides enhanced particulate soil suspension capability with no loss in sudsing or grease cutting properties.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a brightening agent composition, and more particularly to an i-light duty liquid detergent for dishwashing.

More particularly, the present invention provides dishwashing liquid detergent compositions that are formulated to ensure improved particulate soil removal ability without compromising other performance areas, such as 'grease and oil stain removal and foaming ability. relating to things.
: □ □The greasy nature of most food residues and (
Or 9 oiliness, with a satisfying capacity of 100 ml, is applied over the course of a dishwashing job, with grease and oil stain removal being the primary focus of dishwashing agent performance.

This is reflected in the formulation of liquid detergent products exclusively formulated for dishwashing.

, this type of product usually consists of a combination of one or more surfactants and foam bilge dissolved or dispersed in a hydrotrope-water system.

Liquid dishwashing detergent formulations of this type include magnesium salts and magnesium surfactants, such as alkyl sulfates, alkyl ether sulfates and alkylbe/zenesulfonates, and are described in British Patent No. 1,5
24,441, □1.551,074, 2,010,893A and European Patent Application Publication No. 0039110.

A representative disclosure of the state of the art. The art teaches that these formulations have increased performance, especially when used in water of low mineral hardness.

Alka/sulfonates and liquid dishwashing detergent compositions containing alkali/sulfonates are also known; examples of disclosures of this type are GB 1,050,848, GB 1,339,069. Book, No. 1,382, 29
Specification No. 5, Specification No. 1,451,228, No. 1. ,
．． 551.0"74. Specification and No. 1,567.4
This is from Specification No. 21.

This type of formulation, which uses a total amount of surfactants in excess of the stated weight, cannot tolerate significant amounts of inorganic detergent virgoux salts while retaining a clear single-phase solution form, and additionally , the presence of inorganic salts results in aesthetically undesirable residue on washed ceramic tableware or tableware. Accordingly, these formulations are usually substantially completely free of detergent builder salts, and metal chelating agents, if included, are used only in trace amounts. “Also, particulate matter is also a significant component of food residue, and the fact that detergent bilgo substances are present in small amounts or not at all in regular dishwashing liquid detergents makes these formulations The composition of the ingredients, more specifically the alkaline earth metal alkyl sulfates and the ethoxylated alcohols, is not optimal both in terms of foam stability in the presence of dirt and particulate dirt suspension during the cleaning process. It has now been discovered that a combination of species provides unexpected improvements in particulate soil handling ability without sacrificing the grease and oil stain removal performance of dishwashing liquid formulations.

- The use of ethoxylated alcohols as ingredients in liquid dishwashing detergents is known in the art and is described in British Patent No. 1,567,421 and British Patent No. 1,
No. 551,074.

However, the claimed benefits of these formulations are primarily in the area of suds enhancement and very little in grease removal. Additionally, the use of ethoxylated alcohols in liquid dishwashing detergents is limited by the elevated chill point temperatures they produce. For example, incorporation of ethoxylated alcohols into formulations such as those described in EP-A-0039110 results in products exhibiting insufficient performance benefits as well as completely unacceptable stability properties. Thus, the discovery that the compositions of the present invention have particulate soil removal ability as well as acceptable physical properties is even more unexpected.

According to the invention, therefore, water-soluble C□3-C18 alkano or alkenosulfonates in hydrotrope-water systems, water-bathable alkyl ether sulfates (the alkyl groups have from 10 to 16 carbon atoms and the ether groups are on average a surfactant mixture prepared by a combination of an ethoxylated 08-C□2 primary alcohol) and an ethoxylated 08-C□2 primary alcohol; Compositions 6-18

A clear homogeneous liquid detergent composition having a chill point of C or less is provided.

The present invention consists of a surfactant system containing an olefin sulfonate, an alkyl ether sulfate, an alkyl sulfate, and an ethoxylated nonionic surfactant component in a liquid vehicle consisting of a hydrotrope and water.

The alkyl sulfate surfactant component is a primary furkyl sulfate heptaate in which the alkyl group preferably has 10 to 16 carbon atoms, more preferably an average of 12 to J5 carbon atoms, in the alkyl chain. C1o-C derived from natural fats or Ziegler olefin augmentation or oxo synthesis

The alkyl sulfate component is 6 to 18% by weight of the composition.
, more generally present in an amount of 8-16% by weight.

For the purposes of this invention, the alkyl sulfate is a source of magnesium ions that can be introduced as an oxide or water sulfate or added to the composition as a water-soluble salt to neutralize the acid, as described below. will be met. but,
When significant amounts of magnesium salts are added to the dishwashing compositions of the present invention, the inorganic salt crystals increase the temperature that occurs in the composition upon cooling and are therefore less preferred. The molar amount of magnesium ion in the composition is 0.40-0.60M,
It is preferably controlled to correspond to 45 to 0.55 x (where X is the number of moles of C□0-C□6 alkyl sulfate present). Most preferably, the magne/lam ion content is adjusted to provide chemical softening of the alkyl sulfate present. In practice, the magnesium ions are present in an amount of 0.15 to 0.70% by weight of the composition, preferably 0.35 to 0.60% by weight.

The /ξ roughinosulfonate (S-alka/sulfonate) component or the alpha-olefin/sulfonate (alka/sulfonate) component constitutes 3-15% by weight of the formulation, more preferably 4-12% biwax. The secondary alkali/sulfonates useful in the present invention preferably have - from 13 to 18, most preferably from 14 to 17 carbon atoms per molecule - and are used for food detergent compositions. Characterized by high water replenishment properties compared to alkyl aryl sulfonates and other sulfuric acid reaction products.These sulfonates are preferably prepared by cutting a graphite corresponding to the chain length according to well-known sulfoxidation methods. The product of the reaction is a primary sulfonic acid which, upon neutralization with a suitable base, yields a water-soluble secondary alkyl sulfonate. Similar secondary alkyl sulfonates can be obtained by other methods, for example by the sulfochlorination method, in which:
Chlorine and sulfur dioxide are reacted with paraffin in the presence of chemical storage, and the sulfonyl chloride produced is hydrolyzed and
It is then neutralized to form a secondary alkyl sulfonate. Whichever technique is used, the monosulfonate has no unreacted, carbonized water, or only a limited proportion of the inorganic salt byproduct. 1 It is generally desirable to be produced rarely or never at birth. Similarly, disulfonates or higher sulfonated substances or proportions may be present to some extent, although they will be limited. Monosulfonate has a sulfonate at the end. The sulfonate group can be attached on the 22 carbon or other carbons of the linear chain.

Similarly, sulfonate is commonly produced when an excess of sulfonate/containing agent is present. Entrained disulfonates have sulfonate groups distributed over different carbon atoms of the Tsukurafi base. , and mixtures of monosulfonates and disulfonates can be present.

alkafka carbon numbers 14 and 15, and the sulfonate is C□4-ξ rough, and the ratio of in to C□5 paraffins is 1:, 3 to 3:1. Particularly preferred are mixtures of monoalkanosulfonates present in the range of 1:2 to 221, preferably 1:2 to 221. Surprisingly, this particular mixture cleans dishes better and produces a detergent that foams for a longer time, especially in hard water, than other mixtures of flea fin sulfonates, such as those having 13-117 carbon atoms. This is also true, to a lesser extent, of the individual components of the mixture of C14 and 015. □ The term "α-olefin/sulfonate" or "alkeasulfonate" refers to the sulfonation of α-olefin with simple sulfur trioxide, and the sulfonate produced during the post-sono reaction is hydrolyzed. hydroxyalka/

Sulfur trioxide can be in the form of a gas or a gas, and is usually, but not necessarily, used in liquid form with an inert diluent, such as liquid SO□, salt-accumulated hydrocarbons, etc. When used in a gaseous state, it is diluted with air, nitrogen, gaseous S02, etc.

It is a chain opening. Olefin inoles having a carbon number greater than 16 do not provide the desired high foaming performance in the mixtures according to the invention, while those having a carbon number less than 12 have reduced detergency. In addition to the alkeasulfonate and the proportion of hydroxyalka/sulfonate, the olefin/sulfonate can contain traces of other materials resulting from impurities in the olefin feedstock and from side reactions during the sulfonation and neutralization processes. .

Alkyl ether sulfate component C, to C1o0□6
It consists of a primary alkyl ethoxy sulfate derived from a condensation product of an alcohol and 0.5-6 ethylene oxide groups. C□. The ~C□6 alcohol itself is obtained from the sources mentioned in the case of the alkyl sulfate component. However, it has been found preferable to use alkyl sulfates, alkyl ether sulfates, and alkyl ether sulfates having a carbon chain length distribution of -. 012-C, alkyl ether sulfates are preferred, and the amount of alkyl ether sulfate in the composition is from 0.5 to 20% by weight of the composition, generally from 4 to 1%.
It is in the range of 4M amount%.

Typical average degrees of ethoxylation are 5 to 3 groups per mole of alcohol, but common ethoxylation methods range from 1 to 10 ethoxylate groups per mole of alcohol. The average can be obtained in a variety of ways. Formulations can be prepared from materials with different degrees of ethoxylation and/or different ethoxylate distributions resulting from the particular ethquination technique used and subsequent processing steps, such as distillation. In fact, foaming and degreasing performance equivalent to that provided by a blend of alkyl sulfate and alkyl ethoxy ether sulfate reduces the overall degree of ethoxylation and increases the It has been found that by using alkyl ether sulfates the proportions are the same as those obtained by mixing separately produced surfactants.

Cations other than magnesium that can be used to neutralize the anionosurfactant can be sodium, potassium, ammonium or alkanol amemonium, with ammonium being the preferred cation due to its lowering effect on the chill point temperature of the composition. / is. A preferred composition is 0

The remainder of the formulation consists of a hydrodrosi aqueous system and the hydrotrope is urea, C□-C3 alkanoya, or lower abcape:/ze, sulfo, acid salts, such as echatorue/sulfonate, cumenosulfonate or xine/sulfonate. Can be numbered. A preferred hydrotrope is ethanol used at 3-10%'', preferably 4-8% by weight of the composition.

Components optionally added to the liquid detergent composition of the present invention include, for example, thickeners, such as guar gum.

Antibacterial agents 1 such as glutaraldehyde and Bronopol®, anticorrosive agents such as benzox-7 triazole, heavy metal chelating agent,
For example, EDTA or E'I)TM.P, perfumes and dyes. The pH of the composition can be any pH within the range of 6 to 7.5, but as prepared the composition is typically within the range of 6.6 to 7.3 to maintain color stability. 5 preferably has a pi (of 6.6 to 6.9).

The technique of incorporating magnesium ions is not believed to be critical, and the compositions can be prepared in a number of ways.

The individual anionic/surfactant is prepared as an aqueous solution of the alkali metal or am/monium salt, and this aqueous solution is then mixed together with the idrotrope and the foam enhancer, if formulated, after which the aqueous ions are It can be introduced as a water-soluble salt, for example chloride or acetate. Then, the optional trace ingredients are added, and the pH and viscosity are then adjusted. This method has the advantage of utilizing conventional techniques and equipment, but introduces additional chloride or acetate ions that increase the chill point temperature (the temperature at which inorganic salts precipitate as crystals in a liquid).□ Another method of carrying out the invention is to mix the alcohol and alcohol ethoxylate together and carry out one round of sulfation and neutralization. In this case, the alcohol and alcohol ethoxylate are :1 to 1:5.5. Sulfation can thus occur using conventional sulfating agents such as sulfur trioxide or chlorosulfo/acids. Neutralization is carried out using a magnesium oxide or magnesium hydroxide slurry that avoids chloride removal or addition of sulfate iodine.

Although not required, it is convenient to use mixtures of these acids since the magnesium salt of the alkyl ether sulfate has relatively higher water solubility than the alkyl sulfate component. then separately neutralized grafuinos bufo heptaate,
and neutralize alkyl ii! The c acid salt and alkyl ether sulfate and hydrotrope are added to the final bath and the pH is adjusted as above.

Another preferred variation in the history of the art involves the preparation of a single alcohol ethoxylate feedstock whose composition is the same as or similar to the composition of a mixture of alcohol and alcohol ethoxylate.

For the purpose of the present invention, the average degree of ball toxization is 0.5 to 1.
．． 0, more usually alcohol ethoxylate having a sail of 75 to 0.95.

Variations on this latter technique may also be used. In this variant, either the neutralized /e roughin sulfonate or the neutralized alkyl sulfate/alkyl ether sulfate mixture is used as a heel to neutralize the acid form of the other, thereby Avoid local overheating, viscous phase formation, etc.
