FIELD 'OF THE INVENTION PRIOR ART Secondary alkyl ethoxylates are old having been disclosed in U.S. Pat. 2,355,823.

This patent, however, does not disclose that certain specific secondary alkyl ethoxylates will act as suds suppressors when mixed with amides. The combination of certain zwitterionic detergents and alkyl ethoxylates is disclosed in U.S. Pat. 3,351,557. This patent also does not disclose secondary alkyl ethoxylates specifically. 'None of the prior art patents disclose that there is any criticality, with respect to reduced sudsing, in selecting secondary alkyl ethoxylates for use with certain specific sudsing surfactants.
SUMMARY OF THE INVENTION The compositions of this invention are low-foaming hard-surface cleaner compositions consisting essentially of:
(a) From about 1% to about of a primary surfactant selected from the group consisting of:
(1) the condensation product of a straight chain primary alcohol containing from about 8 carbon atoms to about '16 carbon atoms and having an average carbon chain length of from about 10 to about 12 carbon atoms with from about 4 to about 8 moles of ethylene oxide per mole of alcohol,
(2) an amide having the formula Rd-N(R )2 wherein R is a straight chain alkyl group containing from about 7 to about 15 carbon atoms and having an average carbon chain length of from about 9 to about 13 carbon atoms and wherein each R is a hydroxyalkyl group containing from 1 to about 3 carbon atoms,

(5) Mixtures thereof;
(b) From about 1% to about 3% of a suds suppressor and surfactant which is the condensation product of a straight chain random secondary alcohol having a chain length of from about 11 to about 15 carbon atoms and having an average length of from about 12 to about 15 carbon atoms with from 0 to about 3 moles of ethylene oxide;
(c) From about 10% to about 50% of a sequestrant builder selected from the group consisting of alkali metal and ammonium aminopolycarboxylates, organic polyphosphonates, polymeric carboxylates, pyrophosphates and tripolyphosphates;

The amount of the primary surfactant in the compositions of this invention is determined by the cleaning requirements and the type of product desired. There is usually from about 1% to about 10% of this component in the composition. When the product is in the form of a liquid, however, it is preferred that the primary surfactant range from about 2% to about 5%, more preferably from about 2% to about 3%, of the composition.
Specific examples of suitable primary surfactants are given hereinafter in the examples.
There is a definite relationship between the amount of primary surfactant and the suds suppressor. There is from about 1% to about 3%, preferably from about 1% to about 2% of the suds suppressor in the composition and the ratio of primary surfactant to suds suppressor ranges from about 4:1 to about 0.7:1, preferably from about 2:1 to about 1:1, and most preferably from about 1.5 :1 to about 1:1. The preferred ratio is 1.5 1. The suds suppressor keeps down the level of suds when the prodnet is being used to clean hard surfaces in a diluted form and more importantly it suppresses sudsing when the product is being diluted in the housewifes bucket under conditions which involve higher concentrations of surfactant and greater agitation. The housewife wants a minimum amount of suds in a hard surface cleaner, especially where the housewife does not rinse the surface after the washing step. The suds suppressor of this invention lowers the level of suds for the specific primary surfactants of this invention, but not for conventional anionic synthetic surfactants such as alkyl benzene sulfonates. Furthermore, if the corresponding primary alkyl ethoxylate is used instead of the random secondary alkyl ethoxylate, the reduction in sudsing, especially during dilution in the bucket, is much less pronounced. This is totally unexpected. These suds suppressors do not harm the cleaning effectiveness of the composition and even contribute to the cleaning effect. The preferred suds suppressor is the condensation product of a random secondary straight chain alcohol having from about 11 to about carbon atoms and an average of about 13 carbon atoms with about 3 moles of ethylene oxide per mole of alcohol.
The compositions also contain a sequestering builder. Suitable builders include the alkali metal (e.g., sodium and potassium) and ammonium (including substituted ammonium, e.g., triethanolammonium) aminopolycarboxylates, organic polyphosphonates, polymeric carboxylates, pyrophosphates, and tripolyphosphates. Suitable aminopolycarboxylates are those described in US. Pats. Nos. 3,329,617 and 3,336,233. Suitable polyphosphonates are those described in US. Pats.

liquid, it is desirable to have from about 2% to about 12% of a hydrotroping agent to keep the composition homogeneous under varying storage conditions. Mixtures of alkali metal, ammonium and/ or triethanolammonium isopropyl benzene sulfonate and the equivalent salts of either xylene, toluene or benzene sulfonate in ratios of from about 10:1 to about 0.5:1 are preferred since they are more effective than the individual hydrotropes. The isopropyl benzene sulfonate is also effective.
The compositions can also be in the form of stable emulsions. For such emulsions, the hydrotrope should be omitted and an emulsion stabilizer added in amounts from about 0.5% to about 2%, preferably from about 0.8% to about 1.5%. Acrysol ASE-J08, a commercial product, is preferred. The compositions can also contain numerous miscellaneous ingredients such as dyes, pigments, perfumes, ammonia, etc.
The following examples demonstrate the advantages of this invention, but should not be taken as limiting its scope.
EXAMPLE I The compositions listed in the following table were tested for cleaning hard surfaces, the amount of suds produced on the surfaces cleaned, and the amount of suds generated when the compositions were diluted with water in a bucket. All of the compositions cleaned the surfaces well and gave acceptably low suds on the surfaces cleaned. However, the amount of suds generated in the bucket varied remarkably depending on whether a. secondary alcohol ethoxylate or a primary alcohol ethoxylate was used.

The two tests are as follows: In the first the detergent composition is added first, then the water is added from a tap at a standard height and the suds measured. In the second test the Water is added first, then the detergent is added and agitation is provided by repeating five times in a. minute the steps of dipping a sponge into the water and then wringing it out; the suds are then measured.

The above compositions clearly demonstrate the unobvious advantages, with respect to bucket sudsing, of the secondary alkyl ethoxylates as compared with the primary alkyl ethoxylates.
