2,999,069 DETERGENT COMPOSITION Joseph N. Masci, Metuchen, and Normand A. Poirler,

South River, N.J., assignors to Johnson & Johnson, a

corporation of New Jersey No Drawing. Filed Nov. 18, 1957, Ser. No. 697,290 24 Claims. (Cl. 252-152) This invention relates to synergistic compositions comprising an amphoteric nitrogen-containing organic detergent material and a so-called nonionic detergent.

Various organic detergents have achieved considerable commercial success. However, the art is still confronted by the problem of providing detergent compositions which foam efliciently and yet are free from undesirable disadvantages, such as irritation and the like.

The discoveries associated with the invention relate to solution of the above problems, and the objects achieved in accordance with the invention as set forth herein include the provision of compositions useful as detergents, such as shampoos, comprising:

(1) A reaction of an alkylaryloxypolyoxyethylene sulfate with a product of condensation of sodium chloro acetate with a reaction product of a fatty acid having 12 to 18 carbon atoms in the molecule and an alkylenediamine, or a product which is represented by the formula:

or a mixture of that compound with the corresponding aminoamide in which the CH COOM is replaced by H, the molar amount of aminoamide in all cases being less than the molar amount of ampholyte, and the molar excess of Y or being no more than 20% or 5%, respectively, M is a member of the group consisting of alkali metals, triethanol ammonium, mixtures of an alkali metal with hydrogen, and mixtures of tr-iethanol ammonium with hydrogen, n is a whole number from 0 to 9, inclusive, m is a number from 1 to 23, inclusive, and p is a whole number from 11 to 17, inclusive, and

(I I) A water soluble nonionic surfactant comprising a polyoxyethylenated derivative of a hydrophobic base, said derivative being a member of the group consisting of:

(a) 9-18 carbon atom fatty acid monesters and diesters of aliphatic polyhydric alcohols, the polyhydric alcohols containing at least 3 hydroxyls, reacted with at least 10 moles of ethylene oxide and having a cloud point of at least 85 C. determined at 2% concentration in distilled water, and

(b) A member of the group consisting of the reaction products of 9-18 carbon .atom alcohols, acids, amides and mercaptans, 1224 carbon atom alkyl phenols and alkyl cyclohexanols, and polypropylene glycols having a molecular weight of about 800-2500, with at least 20 moles of ethylene oxide, said reaction products having a cloud point of at least 100 C. determined at 2% concentration in distilled water.

Optionally there may be included a hair conditioner,

- such as a fatty acid ester of a cyclized carbohydrate; a

amino content in terms of moles.

glycol ester; a glyceryl ester; lecithin; and lanolin.

In each ampholyte preparation, the starting material is composed of thecondensation product of a fatty acid (e.g., lauric acid) and an appropriate amine (e.g., 2-hydroxyethylethylenediamine). The amino content of this condensation product is determined by titration to give the weight of product containing one Weight equivalent of titratable amino. A given weight of the condensation product divided by this equivalent weight expresses the This value, when carried through the ampholyte solution, expresses the active amino content of that ampholyte solution as total moles of amino group. Thus, in a combination with the appropriate anionic modifier, the moles of amino of the ampholyte solution will determine the number of moles of anionic to be combined into salt form, and in practice at least of the active amino content of any ampholyte solution is contributed by the ampholyte and aminoamide.

The following examples are presented for the purpose of illustrating the invention and not as a 'limita tion. Parts and percentages are expressed on the, basis of weight of active material unless otherwise indicated. i I

EXAMPLE 1 Part A In a reaction vessel capable of withstanding at least 15 p.s.i. pressure, having a corrosion resistant inner surface (e.g., glass, stainless steel, or the like), equipped with an agitator, reactant inlet means, indirect heating means (e.g., a steam coil, electrical heater, or the like), evacuating means, (e.g., a conventional vacuum purnp),'and

a condenser, there are-charged: 15.27 parts (0. 1316 mole) of sodium chloracetate (in 40 parts of aqueous solution having apH of 8.5-) and 40 parts (0.1316 mole) of an aminoamide,

(which may be prepared by themethod of Morgan et al., 2,344,260), and the mixture is heated and maintained at 50? C. with agitation for about 15 to 20 minutes, then i of this material remains clear at pH range of about] to 6 and at pH range about 8 to 12 but is strongly turbid at about pH 6.5 to 8.9, the pH changes being made by adding aqueous sodium hydroxide or aqueous hydrochloric acid, as required.

Patented Sept. 5, 1961 H 3 Part B In a suitable reaction vessel, such as of the above type, there are charged: 20 parts of the above clear, light amber product of A (containing about 0.027 mole of amino, principally the carboxymethylated derivative of the aminoamide) 49.5 parts (0.027 mole) of an anionic surfactant (commercially available in the form of about 25 to 30% aqueous solution) of the following structure:

and the mixture is heated at about 70 to 80 C. for two hours with agitation. During this period all the isopropanol is distilled ofl (no odor of isopropanol is discernible in the vapor rising from the reaction mixture at the end of this period). The resulting mixture is a paste weighing about 45.5 parts.

This mixture is diluted with 60 parts of water, and the final product is an amber-colored liquid of pH 8.2 and containing about 25% dry solids and weighs about 105.5 parts.

It has the following structure:

with a minor part of the corresponding sulfate salt of the following aminoamide:

ll l I CnHzr-G-N-CHrCH N-OHaGEbOH Part C In a suitable vessel, such as of the above type, there are mixed:

14 parts by weight of a polyoxyethylenated sorbitan ester (commercially available sorbitan monolaurate containing about 20 oxyethylene groups per molecule) 11.2 parts of active surfactant B (having a pH of 8.2)

72.74 parts of water and the pH is adjusted to about 7 by adding aqueous hydrochloric acid or caustic so1ution,as required.

This product shows very low irritation to the human eye and eyelid surface and 1% and 5% concentrations thereof in water foam copiously on shaking. It is eminently, suitable as a shampoo for washing human hair.

In this example the molar ration of unmodified amphd lyte plus aminoamide to modifier is 1:1.

The polyoxyethylene derivative of sorbitan monolaurate used in this example had a cloud point above 100 C. when determined at 2% concentration in distilled water, as defined hereinafter.

In another such composition, there are included:

1.25 to 1.5 parts fatty ester hair conditioner (commercially available sorbitan monolaurate) 0.5 part boric acid (optionally) 0.06 part perfume.

and the resulting material is equally good as to non-irritation and as to foaming properties; but is superior as a shampoo, inasmuch as it leaves the hair conditioning agent on the hair. 7

Forty-four and fourteen hundredths parts of the above solution was mixed with 16.8 parts of the reaction product of sorbitan monolaurate and 20 moles of ethylene oxide. The solution was neutralized to pH 7 with hydro- .5 chloric acid and then made up to 100 parts with distilled water.

The final product gives copious foam and excellent cleansing when used as a shampoo. When some of the shampoo accidentally gets into the eyes during use it causes little or no sting if the concentration of surface active material is less than A EXAMPLE 5 EXAMPLE 6 One hundred and thirty-two and two tenths parts of an aqueous solution containing 0.136 mole of N la-uroyl- N carboxymethyl N (2 hydroxyethyl)ethylenediamine and 232.5 parts of an aqueous solution containing 0.136 mole of nonylphenoxytriethyleneoxyethyl sulfate sodium salt were mixed and stirred on the steam bath for 30 minutes in an open vessel. Water was added as needed to reduce viscosity. The final Weight of product was 622 parts, having 18.7% content of organic surface active materials. The molar ratio of unmodified ampholyte to modifier is 1:1. Fifty-eight and eighty three hundredths parts of the above solution was mixed with 14 parts of the reaction product of sorbitan monolaurate and 20 moles of ethylene oxide. The solution was neutralized to pH 7 with hydrochloric acid.

The resulting product is mild to the skin and gives copious foam and strong cleansing action when used with hard or distilled water.

The mixture was stirred in an open container for 1 hour at 60-70 C. The solution, which weighed 468 parts, contained 166 parts of active material. The molar ratio of unmodified ampholyte plus aminoamide to modifier is about 0.97:1. Twenty-nine and forty-nine hundredths parts of the above solution containing 10.48 parts of active surfactant (polyether sulfate ester salts of the above amphoteric and aminoamide), was mixed with 14 parts of the reaction product of sorbitan monolaurate and 98 moles of ethylene oxide. This polyoxyethylene derivative of sorbitan monolaurate had a cloud point above 100 C. when determined at 2% concentration in distilled water.

This reaction product of lauryl alcohol and ethylene oxide had a cloud point above 100 C. when determined at.2% concentration in distilled Water.

A product was obtained which had similar foaming mucous membranes when the concentration of surfactants in water was 2.7% or less.

EXAMPLE 9 Example 3 was repeated, except that 14 parts of the reaction product of nonylphenol and 30 moles of ethylene oxide was-substituted for 14 parts of the reaction product of sorbitan monolaurate and 20 moles of ethylene oxide. The mixture was neutralized to pH 7 with hydrochloric acid. This reaction product of nonylphenol and ethylene oxide had a cloud point above C. when determined at 2% concentration in distilled water.

The neutral product gave excellent foam and was useful as a mild detergent for cleansing skin.

EXAMPLE 10 Four hundred and twelve parts of an aqueous solution, containing 66.6 parts (0.179 111016) of N-lauroyl-N- sodium canboxymethyl N (2 hydroxyethyl) ethylenediamine and 10.4 parts (0.0362 mole) of N-lauroyl-N-(2- hydroxyethyDethylenediamine was mixed with 304.9 parts of a solution containing 89.5 parts (0.179 mole) of the following surface active agent:

Then 18.9 parts (0.195) mole of sulfamic acid is added in portions over about 30 minutes, during which time the reaction temperature rises to 122 C. When the solution is complete, the mixture is heated for an additional 2 hours at Ill-121 C. The reaction mixture is allowed to cool, and the viscosity is decreased by addition of a quantity of aqueous ethanol (50%) suflicient to allow a smooth stirring rate. Sixteen parts of 50% sodium hydroxide solution is added dropwise over a period of 30 minutes. Heating and stirring are continued until the evolution of ammonia and ethanol has ceased (about 8.5 hours). The product weighs 263 parts and consists of about 68.7 parts of active anionic material.

The reaction product of coconut fatty acids and ethylene oxide had a cloud point above 100 C. when determined at 2% concentration in distilled water.

The product is mild to the skin and shows excellent cleansing action when used as a hair shampoo.

EXAMPLE 16 Example 4 was repeated except that the acid portions of the N-acyl-N-sodium carboxyrnethyl-N-(Z-hydroxyethyl) fatty ethylenediamine and the N-acyl-N'-(2-hydroxyethyl) ethylenediamine were derived from an approximately 1:1 mixture by weight of lauric and coconut fatty acids. 11 parts (active basis) of the resulting amphoteric anionic products are mixed with 14 parts of the reaction product of 136-160 moles of ethylene oxide with one mole of a polypropylene glycol having a molecular weight of from 1501-1800.

After neutralization to pH 7 with hydrochloric acid and adding distilled water to make 100 parts, a product is obtained which gives copious foam and excellent cleansing and low sting when used as a shampoo.

EXAMPLE 17 Example 16 was repeated, except that the same amount of the reaction product of sorbitan monolaurate and 10 moles of ethylene oxide was substituted for the polyoxyethylenated polypropylene glycol. The polyoxyethylenated sorbitan monolaurate had a cloud point of C. when determined at 2% concentration in distilled water.

The resulting shampoo gave similar results to that of Example 16.

TABLE 1 In the table below percent active signifies percent by weight of the indicated ingredient. The Amphoteric Ingredient column and Amphoteric-Nonionic column include not only the indicated surfactant but also anionic surfactant. The anionic is combined with the amphoteric in salt form. d denotes foam tests carried out in distilled water and h signifies that the foam tests were carried out in distilled water containing 300 p.p.m. calcium chloride.

All solutions were adjusted to pH 7, but it has been found that there is no substantial difference in foam when measured at small variations therefrom.

Not all compositions which show synergism will show it at exactly the same concentration. Some, however, show synergism at all of the concentrations tested. In

the use of a shampoo best cleaning is generally obtained in the concentration range of 1 to 10%. However, good foaming is desirable even at lesser concentrations.

The example data show that the amount of foam obtained with the mixture of organic surface active material from 'the amphoten'c solution and polyoxyethylene cyclized carbohydrate ester of the invention is greater than, and is unpredictable from, the foam obtainable with either of these compounds alone.

Although the para-alkylphenoxy modification of the anionic component is preferred because of commercial availability, the ortho or themeta, or mixtures thereof, give equally satisfactory results, as do di-or tri-alkyl modifications. Suitableexamples are p-l,1,3,3-tetramethylbutylphenoxy-, p-nonylphenoxy-, 2,4,6-trihexylphenoxy 2,4-.dibutylphenoxy-, 2,4-din0nylphenoxy-, 2,4,6-tripropylphenoxyand p-dodecylphenoxy-polyoxyethyl sulfate.

In any of the formulae herein the sodium may be replaced wholly or in part by other alkali metalor substituted alk-anol ammonium (such as trieth-anolamrnonium), or replaced in part by hydrogen, depending on the pH.

The amount of polyoxyethylenated material maybe in the range of about 2 toabout GOO-or more, per 100 parts of the nitrogen containing surfactant, and preferably the amount that gives a mixture.havingmajorfoampurposes, and those containing more than 18 carbon.

atoms tend to be so insoluble as to give-turbid or unattractive mixtures. Other conditioners'which may be used include fatty acid esters of glycerol orthe glycols, lanolin or lecithin. Generally, the amount of conditioning agent 7 is in the range of about 0.5 to 2.0% based on the weight of the total mixture. 1

From the above discussion it will be apparent that We have developed a group of compositions which make excellent shampoos, andin which the foam produced by a combination of alkyl phenoxypolyoxyethylene alkali metal sulfate modified ampholytes, in a molar ratio of unmodified ampholyte (and aminoamide if any) to modifier of from about 0.95:1 to 1.2:1, and certain nonionic surfactants having a cloud point of at least about (3., determined at 2% concentration in distilled water, is unexpectedly greater than the foam produced by either of these components alone.
