Description:
FIELD OF INVENTION 
       [0001]    The present invention relates to laundry detergent formulation for hand wash and/or machine wash comprising a delay antifoam composition and, in particular, relates to powder or liquid composition comprising an amino silicone antifoam fluid in combination with a water soluble filler material that would meet consumer&#39;s acceptability of detergent in hand wash and/or machine wash laundry applications involving: 
         [0002]    a. Good foam during washing i.e. during prewash or post wash 
         [0003]    b. Faster rinsing 
         [0004]    The present invention thus provides a delay antifoam detergent that would be capable of sufficiently depressing foam at the rinsing stage but would not affect the foam depression in the washing stage and would thus meet the consumer&#39;s preferences for such detergent formulations in hand wash and/or machine wash laundry applications. 
       BACKGROUND 
       [0005]    Today hand washing laundry is the main washing habit for developing &amp; emerging (D&amp;E) countries all over the world. It is also true that hand washing laundry will continue for some more decades due to socio economical reason. Especially, lower income people are the main user for hand wash laundry. In many D &amp; E countries, hand wash laundry detergent is still available for less than one dollar per kilogram and lower income people are getting clean water at free of cost. These points are the basic reasons for continuing such laundry habit for longer time. Consumers in hand wash laundry believe that detergent producing good amount of lather during washing is the best quality detergent for removing dirt from fabrics i.e. foam quantity during the washing in hand wash laundry is very important. As a result, multiple numbers of rinsing is required during the rinsing stage for removing excessive foam from the fabrics i.e. huge amount of clean water is used during the hand wash laundry only for removing loam from rinsing water although realistically residual dirt gets removed from fabric after 1 to 2 rinses. 
         [0006]    In hand washing process, water is taken in a bucket or in fabric&#39;s soaking container or in case of machine washing process water is taken in a washing tub in washing machine. Thereafter, desired quantity of detergent is added to generate lather by hand shaking or the washing tub in washing machine is run for a while. This is followed by immersion of the dirt fabrics for soaking for 10 to 30 min. After soaking period, the fabric is rubbed by hand to remove dirt or the washing cycle is run for 10 to 20 min in case of machines wash. 
         [0007]    For rinsing, the dirt water is drained out and excess dirt water is removed by squeezing the fabrics. Thus each such rinsing cycle consists of squeezing the fabrics and rinsing the fabrics with fresh water. Such rinsing cycle is repeated for four to five times for hand wash or in case of machine, four to five times rinse cycle is followed to remove all foams before final spinning. It is also a fact that in some areas people are paying higher amount of price for water used in rinsing due to the fact of using high foaming detergent in hand wash laundry. It is also a fact that consumers in hand wash laundry is not only spending extra money for rinsing water or wasting clean water in rinsing stage due to foam but also spending longer laundry time to complete one hand wash laundry. It is also true that consumer in hand wash laundry can buy water for rinsing or don&#39;t care to waste clean water for rinsing but are not ready to pay additional money for hand wash detergent which delivers less water usage in rinsing. 
         [0008]    Attempts have been made in the past to resolve this problem by secondary method, called single rinse concept where during rinsing cycle, use of a defoamer containing fabric conditioner where fabric conditioner conditions the fabric at rinsing cycle and in addition kills all the residual foam. This concept was not very much successful in case of hand washing process, since use of fabric conditioner in this class is considered to be a luxury and people of hand-washing segment uses hand washing due to money constraint for fabric cleaning. 
         [0009]    Considering the billion tons of clean precious water wastage and sensitive formulation cost for normal detergent used in hand wash laundry or machine wash, there has been a need for detergent formulations which when used for washing fabrics most likely generates preferred amount of foaming during washing cycle without affecting the cleaning nature of the detergent but also have antifoaming activity in rinsing cycle so that one or two rinse is enough, to clean the fabric without effecting much detergent formulation cost. It is however extremely difficult to provide for such characteristics in detergent formulations which would favour both the washing and rinsing cycles and make washing of clothes/fabrics more convenient and user friendly apart from taking care of avoiding unnecessary wastage of valuable water and saving the environment from unnecessarily wastage of water in hand wash laundry and/or machine washing. 
         [0010]    EP 0685250A1 disclosed a foam control composition which acts as a foam inhibiting agent in rinsing cycles when use in together with detergent. Table 1 therein reveals washing stage foam height from 2 cm to 9 cm for examples 1 to 4 against blank foam height 13 cm. Therefore, the washing stage foam height deterioration is strongly evident when compared to the blank that is even less than the blank in the case of this prior art composition which constitutes a major drawback or failure to meet the fundamental requirements of good foam control composition favouring same foam height as that of blank or avoiding reduction of foam quantity during the washing stage. Thus the foam control composition of EP 0685250A1 in any hand washing laundry detergent composition cannot be considered beneficial for the consumers desirous of having good foam in the washing cycle and no foaming in just after 1-2 rinse cycles. 
         [0011]    WO2011107361A discloses a delayed antifoam composition that has a polyoxyalkylene group as the terminal group of the polyether containing aminosiloxane. The production of polyether containing amino siloxanes of WO2011107361A is expensive. In practice such materials are produced through equilibrium reaction starting from OH-terminated polydimethylsiloxanes, a, w-polyether-functional siloxanes and hydrolysates of corresponding aminoalkylsilane. There is a major disadvantage that often in this synthesis the two-phase reaction mixture results; since, because of different polarities the polyether siloxane is not compatible with the remaining components. 
         [0012]    DE102012210211A1 also disclosed an antifoaming agent having delayed antifoaming agent in the detergent composition. It would be found that under Examples 1-5 and comparison example in DE102012210211A1 while obliging defoaming during rinsing reveals significant percent reduction of foam during the washing process than the blank sample. Also closer comparison of [%] foam in the washing process as compared to rinse 1 process reveals that the percent foam in the washing process is lesser than the percentage of foam in the rinse 1 process which go to demonstrate that antifoaming action is more active or more inherent in the washing process than in rinsing process and hence not desirable. 
         [0013]    It is thus apparently clear from the above state of art that the delayed antifoam in the hand wash and machine wash does not only suppress foam at the rinsing stage but also suppresses foam in the washing stage, and moreover, for certain antifoam compounds the difficulty in preparing and the involvement of high cost makes it undesirable for use in hand wash or machine wash laundry. 
         [0014]    Thus it is a need in the art to obtain cost-effective laundry formulation that would have sufficient foam depression property in the rinsing stage without affecting the foam height during the washing stage and at the same time would also be easy to synthesize. 
       OBJECTS OF THE INVENTION 
       [0015]    It is thus a basic objective of this invention to provide delay antifoam detergent composition comprising an amino silicone antifoam fluidalong with a water soluble filler material that would sufficiently depress foam in the rinsing stage but not at the expense of affecting/depressing the required foam height in the washing stage. 
         [0016]    Another objective of the present invention is to provide delay antifoam detergent composition which would serve to save fresh water and to reduce the wastage of huge amount of water during the hand wash or machine wash laundry for cloth or fabric washing. 
         [0017]    Another object of the invention is to provide a cost effective antifoam composition for use in diverse application such as in personal care, especially hair care, home care, textile care, and the like.

         [0038]    Yet unexpectedly and most importantly it was also found by way of the present invention that upon reducing the carbon chain lengths of the both the alkyl groups on the silicon atom on the main siloxane chain to C1 i.e. by employing both alkyl groups as methyl on the said Si atom of the antifoam compound of the present invention together with a water soluble carrier filler as a formulation/composition, the said superior effect of absolutely no suppression of foam height during the washing stage and advantageous suppression of foam height in the rinsing stage died down, which could be regained when one methyl was replaced by an ethyl substituent. Thus while the superior effect died down when R═R 2 ═CH 3  on the Si atom of the main siloxane chain the surprising and unexpected special effects of no foam reduction in wash cycle and foam reduction in rinse cycle was again observed when the alkyl groups on the silicon atom on the main siloxane chain of the defoamer of the present invention involves R and R 2 , being selectively defined as

         [0183]    According to another aspect of the invention there is provided a process for preparing the antifoam powder comprising the steps of 
         [0184]    (i) Transfer carrier filler in the mixer and mixture used for manufacturing powder defoamer is a standard powder liquid mixture like plough shear mixture where liquid addition in the powder can be done with certain flow rate by dripping or by spraying. Carrier filler should have low moisture (less than 2%). If moisture is high then the carrier filler is dried at 100° C. to 150° C. till it reach to less than 2% moisture, 
         [0185]    (ii) Dripping or spraying of amino silicone antifoam fluid of formula (I) on carrier is carried out at room temperature. 
         [0186]    As discussed hereinbefore the present invention relates to an antifoam powder involving delay antifoam composition, and in particular, relates to the preparation of the said antifoam powder comprising amino silicone antifoam fluid absorbed in carrier filler, which can be used in laundry detergent formulation specially in fabric wash adapted for, excellent antifoaming effect in rinsing cycle while maintaining almost similar foaming nature compare to ‘detergent without antifoam’ in washing cycles. 
         [0187]    Advantageously, the said detergent composition involving the delay antifoam composition is found to have excellent antifoaming effect in rinsing cycle while preferred foaming effect in washing cycle. 
         [0188]    The present invention also relates to a process of synthesis of the amino silicone antifoam fluid based delay antifoam compound present in the said antifoam powder for use in detergent formulation wherein the said silicone compound generates preferred in-situ foaming properties of the said detergent formulation in washing cycle but acts as antifoam in rinsing cycle. 
         [0189]    According to the present invention, performance of powder silicone antifoam comprising amino silicone antifoam fluid is confirmed by a unique mechanism that governs its role as an antifoam agent in rinsing cycles while maintaining preferred amount of foam in washing cycles. 
         [0190]    Effective detergent compositions comprise anionic surfactants, particularly alkyl benzene sulfonate and alkyl sulfate surfactants. It has also been found beneficial for the appearance and cleaning of fabrics for laundry detergents to contain an amount of a cellulose enzyme sufficient to improve the appearance and cleaning of such fabrics, particularly after multiple cleaning cycles. But this anionic surfactant is important for cleaning and cheap source of generating substantial foam in the washing even at small amount. 
         [0191]    In detergent powder, main foaming component is anionic surfactant. According to the present invention, when laundry detergent containing powder silicone antifoam is dissolved in water, huge amount of foam generates due to anionic surfactant and no interaction takes place between amino group of amino silicone antifoam fluid and anionic surfactant due to weak alkalinity of organic amine group present in the silicone molecule but on the other hand, during washing stage, washing liquor pKa value (pK a  is the negative base-10 logarithm of the acid dissociation constant (K a ) of a solution. pKa=−log 10 K a . The lower the pK a  value, stronger the acid &amp; higher the pKa value, stronger the base) is around 10-11 where Na +  ion present in the detergent is more preferable to anionic detergent for making salt due to strong Na+ alkalinity. As soon as, the washing fabric come across the said liquor in the washing cycle, the amino silicone antifoam fluid penetrates inside the fiber due to its high affinity towards the fabric due to salt formation between week acidity of fabric and week base in silicone molecule (amine groups) and but due to high lather during washing cycle in machine wash or during rubbing the fabrics in hand wash after soaking with amino silicone antifoam fluid penetrated into the said fabric, the anionic surfactant can&#39;t come towards the amino group of amino silicone antifoam fluid to interact and form salt. Therefore, foaming nature of the detergent during prewash or in post wash does not change. In rinsing cycle, residual detergent transfers into fresh water by way of fabric which is remain after squeezing the washed fabrics. Therefore, pKa value rinsing liquor foam density reduces significantly (˜7.5) due to less amount of detergent present in the liquor and hence, anionic surfactant easily reacts with amino group in silicone, attached to the fabric and form the salt with anionic surfactant. These salts transfer immediately to rinsing liquor and anionic surfactant lost foaming nature due, to salt formation with silicone and hence, foams in rinsing lather are eliminated in significant amounts. Specially, in case of hand wash, no foam is observed after 1 to 2 rinsing. 
         [0192]    The details of the invention, its nature and objects are explained hereunder in greater detail in relation to the following non-limiting examples.

Performance Evaluation (Hand Wash) (Followed as U.S. Pat. No. 8,481,476B2)
 
         [0298]    Protocol used for the evaluation of detergent in bucket by hand washing was as below 
         [0299]    a. used 24° fH hard water 
         [0300]    b. fabric to liquor ratio is 1:10 
         [0301]    c. used 4 gpl detergent (gpl=grams per liter) 
         [0302]    d. lathering is done for 20 sec and immerged the fabrics in bucket water. 
         [0303]    e. washing cycle maintained 15 min or 30 min and measured lather height in every 5 min or 10 min intervals. 
         [0304]    f. squeezed fabrics at 50% weight pick up 
         [0305]    g. rinsing is done in each case in fresh 24° fH hard water in ratio of rinse water 1 part and 7 part fresh water and then see whisking; squeezed fabrics at 50% weight pick up and measured the foam height in bucket. 
         [0000]    Performance Evaluation (Machine Wash) (Followed as in U.S. Pat. No. 8,481,476B2) 
         [0306]    Protocol used for the evaluation of detergent in top load automatic machine 
         [0307]    a. used 24° fH hard water 
         [0308]    b. fabric to liquor ratio is 1:10 
         [0309]    c. used 4 gpl detergent (gpl=grams per liter) 
         [0310]    d. washing cycle maintained 15 min or 30 min. Open the top lid of washing machine just before discharged the washing liquor (as soon as top lid opened, m/c stopped in operation automatically) and took out fabrics by squeezing so that fabric retained 50% wash liquor. After taking out the fabric, the foam height is measured. 
         [0311]    e. The top lid is closed and the machine is run. As soon as machine discharged the washing liquor, opened top lid of the machine and transferred the fabrics in the machine. Closed the top lid of machine and immediately machine is in operation for rinsing cycle. Open the top lid of washing machine just before discharged the 1 st  rinsing liquor. Took out fabrics by squeezing so that fabrics retain 50% washed liquor. After taking out the fabric, measure the foam height and noted as 1 st  rinsing foam height. 
         [0312]    f. Closed the top lid and followed step ‘e’ for foam height measurement of 2 nd , 3 rd &amp; 4 th  rinsing.

         [0313]    Above Table 1 and 2 shows the application result of the detergent produced that contains 1.0% of the delay antifoam composition of the present invention (Examples 1-88 with a water soluble carrier and Example V and VIII on a water insoluble carrier) comprising amino silicone antifoam fluid of Formula I with selective alkyl groups R and R 2  on the main siloxane chain of the fluid of the type R being a monovalent C 1 - to C 6 -alkyl radical and R 2  is a monovalent C 2 - to C 6 -alkyl radical, in combination with water soluble carrier filler, achieved no drop in foam in washing stage either in performance test in hand washing or machine washing whereas amino oil having both alkyl groups C 1  or one of the alkyl group higher than C 6 (In Examples 1-88 with a water soluble carrier specifically Examples 84, 85) clearly showed drop in foam height (means generating less foam during washing) in the performance test even at wide range of amine value. Same negative effect of reduction of foam height or less amount of foam is also observed when amino oil synthesized as per patent no DE102012210211A1 (example 86) and EP0685250A1 (example 83) where polymers backbone is methyl methyl groups (both alkyl group is C 1  in amino silicone). 
         [0314]    Above Table 1 and 2 also shows the application results for the detergent produced containing water insoluble carrier filler by using fluid of Example 1, wherein Example V under Table 1 for hand was formulations clearly show that though the foam height retains a 9 cm height comparable to blank that is acceptable at the washing stage, the foam height during rinsing does not quench or destroys the desired observed anti-foaming property of the fluid when present in combination with water insoluble carrier. Further for the machine wash formulations under Table 2 as evident from the tabulated result for Ex-VIII that when the water insoluble filler was present in combination with the antifoam fluid of the present invention the desired anti-foaming effect was lost which otherwise showed a superior effect when present in selective combination with water soluble carrier filler. 
         [0315]    The antifoam compound of prior arts of EP 0685250A1 &amp; DE102012210211A1 clearly reveals low foam during washing in compare to blank detergent (i.e. without silicone defoamer) that is completely undesired of good delayed defoaming composition that causes suppression of the foam during the washing stage. 
         [0316]    Thus, by selectively employing the amino fluid of Formula I of the present invention and having selective alkyl groups disposed on the Si atom of the main siloxane chain in combination with a water soluble carrier filler, it is surprisingly found to not only show no′ suppression of foam during washing stage, but also all foam removal in rinsing stage in just two rinse cycles making the rinsing stage much faster (detergent Exp. 1 to 81, 87 under Tables 1 and 2 above) as compared to the detergent made with amino silicone antifoam fluid made with alkyl groups and carrier fillers (detergent Exp. 82 to 86 and 88, Examples V and VIII under Tables 1 and 2 respectively) of the presently available state of art of antifoams presently in use. This faster rinsing according to present invention not only saves a huge amount of clean water but also total laundry time also reduced significantly. 
         [0317]    It is thus possible by way of the present invention to provide for detergent formulations and the like to favour both washing and rinsing cycles and make washing of clothes/fabrics more convenient and user friendly apart from taking care of avoiding unnecessary wastage of valuable water and saving the environment from unnecessarily wastage of water in hand wash and/or machine washing and the like.
