Description

STARCH GRANULES CONTAINING OIL TO PROVIDE BENEFICIAL ADDITIVES TO A SUBSTRATE This invention relates to a starch granule containing oil comprising a starch which forms a matrix for said granule, an oil and a compound and a structure defined to inhibit the migration of the oil to the surface of the starch granule. More particularly, this invention relates to an oil-containing starch granule capable of delivering a beneficial additive to substrates such as fabrics, hard surfaces, hair and skin, upon contact of the starch granule with such a substrate.

BACKGROUND OF THE INVENTION The addition of the perfume to a liquid detergent composition to impart a pleasing aroma or fragrance to such a detergent composition is well known in the art. The presence of the perfume provides an aesthetic benefit to the consumer with the use of the detergent composition and generally serves as a sign of freshness and cleanliness of the engraved fabrics which contain a pleasing fragrance. However, despite the improved aroma of the detergent composition itself, relatively little fragrance of perfume is imparted to the fabrics during washing. In a primary form, this is because the perfume ingredients in the liquid composition are rapidly dispersed and diluted during the wash in the aqueous wash water and in the rinse waters. Consequently, only a relatively limited amount of the perfume is available to make contact with the fabrics during washing. The main part of the perfume is drained from the washing machine in the washing solution. There still exists, therefore, a need in the art to improve the effectiveness of the delivery of the perfume of the detergent composition to the washed fabrics and to improve the duration of such fragrance on the fabrics.

Similarly, there is a need in the art to effectively deliver oils other than a fragrance or perfume as beneficial additives to substrates such as hard surfaces, hair and skin so that the duration of such oils on the substrate is significantly improved in relation to to conventional means of providing such beneficial additive to the substrate.

The oils useful for the present invention can be any oil which is a liquid between about 10 ° C and 90 ° C and which is capable of providing a beneficial additive to fabrics, hard surfaces, hair or skin. For laundry applications the preferred oils are perfumes, the term "perfume" being used herein to refer to odoriferous materials which are capable of providing a pleasing fragrance to fabrics and encompass conventional materials * commonly used in detergent compositions for counteract a bad odor in such compositions and / or provide a pleasing fragrance thereto. The perfumes are preferably in the liquid state at room temperature, even when solid perfumes are also useful. Included among the perfumes contemplated for use herein are materials such as aldehydes, ketones, esters and the like which are conventionally employed to impart a pleasing fragrance to liquid and granular detergent compositions. Oils from plants of animals that occur naturally are also commonly used as components of perfumes. Thus, perfumes useful for the present invention may have relatively simple compositions or may comprise complex mixtures of natural and synthetic chemical components, all of which are intended to provide a pleasant fragrance or odor when applied to fabrics. The perfumes used in the detergent compositions are generally selected to meet the normal requirements of odor, stability, price and commercial availability. The term "fragrance" is often used here to mean a perfume itself, rather than the aroma imparted by such perfume.

The other oils which may be useful herein to provide a beneficial additive to one or more of the substrates of aforementioned fabrics, hard surfaces, hair and skin include vitamins such as vitamin E (tocopheryl esters), modified silicone oils and unmodified, surfactants, fabric softeners, fatty alcohols, fatty acids, fatty esters, etc. These oils can be used as such or a combination of any of the mentioned oils can be used.

DETAILED DESCRIPTION OF THE INVENTION The starches which are suitable for the starch granule of the present invention can be made from unprocessed starch or from a modified starch derived from tubers, legumes, cereals and grains, for example corn starch, wheat starch, rice starch. Waxy maize starch, oat starch, cassava starch, waxy barley, waxy rice starch, sweet rice starch, rhizome, potato starch, tapioca starch, oat starch, cassava starch and mixtures thereof.

Modified starches suitable for use include, hydrolyzed starch, acid-thinned starch, long chain hydrocarbon starch esters, starch acetates, octenyl starch succinate, and mixtures thereof.

The term "hydrolyzed starch" refers to oligosaccharide type materials such as corn starch, maltodextrins and corn syrup solids.

The organic compound to inhibit the migration of the oil to the surface of the granule is preferably an amidoamine having the following formula: Rl - CONH (CH2) nN - R3 (I) Where Ra = C12 to C30 alkyl or alkenino; R2 = R2CONH (CH2) m; R3 = (CH2CH20) pH, CH3 or H, n = 1 to 5, m = 1 to 5; and p = 1 to 10.

In a more preferred softening compound of the formula (I), Rx = C 6 to C 22 alkyl, n = 1 to 3, m = 1 to 3; and p = 1. 5 to 3. 5 .

In the formulas given above, R and R2 are each, independently, alkyl or alkenyl groups; of long chain having from 12 to 30 carbon atoms, preferably from 16 to 22 carbon atoms, such as for example dodecyl, dodecenyl, octadecyl, octadecenyl. Typically, R and R2 will be derived from natural oils containing fatty acids or mixtures of fatty acid, such as coconut oil. Palm oil, bait, rapeseed oil and fish oil, fatty acids chemically synthesized are also usable. Saturated fatty acids or mixtures of fatty acid, and especially hydrogenated fatty acid (bait-H) (also referred to as hard bait) are preferred. Generally and preferably R and R2 are derivatives of the same fatty acid or a mixture of fatty acid.

R3 represents (CH2CH20) pH, CH3, or H, or mixtures thereof may also be present. When R3 represents the group (CH2CH20) pH, p is a positive number representing an average degree of ethoxylation, and is preferably from 1 to 10, especially from 1.5 to 6, and more preferably from about 2 to 4, such as 2.5 n and m are each whole from 1 to 5, preferably from 2 to 4, especially 2. The compounds of the formula (I) in which R3 represents the group (CH2CH20) preferred pH are widely mentioned herein as ethoxylated aminoamines and the term "hydroxyethyl" is also used to describe the group (CH2CH20) pH.

The laundry detergent compositions of the invention may contain one or a mixture of surfactants from the group consisting of anionic and nonionic surfactant.

Any suitable non-ionic detergent compound can be used as a surfactant in present laundry detergent compositions, with many of them being described in the various annual numbers of John W. McCutcheon's Detergents and Emulsifiers. Such volumes give chemical formulas and brand names for commercial nonionic detergents sold in the United States of America and essentially all of those detergents can be employed in the present compositions. Nevertheless, it is highly preferred that such non-ionic detergents are a condensation product of ethylene oxide and higher fatty alcohol (although when instead of the higher fatty alcohol, higher fatty acids and alkyl [octyl, nonyl and isooctyl] can also be employed] phenols). The higher fat halves, such as the alkyls of such alcohols and the resulting condensation products, will usually be linear, of 10 to 18 carbon atoms, preferably 10 to 16 carbon atoms, more preferably 12 to 15 carbon atoms and sometimes more preferably from 12 to 14 carbon atoms. Because such fatty alcohols are normally commercially available only as mixtures, the numbers of carbon atoms given are necessarily averages but in some cases the ranges of numbers of carbon atoms can be real limits for the alcohols employed and for the corresponding alkyl.

The ethylene oxide (EtO) contents of the non-ionic detergents will normally be in the range of 3 to 15 moles of ethylene oxide per mole of higher fatty alcohol, even though as much as 20 moles of ethylene oxide may be present. Preferably such ethylene oxide content will be from 3 to 10 moles and more preferably will be from 6 to 7 moles, for example, 6.5 or 7 moles per mole of higher fatty alcohol (and per mole of nonionic detergent). As with the higher fatty alcohol, the given polyethoxylate limits are also limits on the averages of the numbers of ethylene oxide groups present in the condensation product. Examples of such suitable nonionic detergents include those sold by Shell Chemical Company under the trade name Neodol®, including Neodol 25-7. Neodol 23-6.5 and Neodol 25-3.

Other useful nonionic detergent compounds include alkylpolyglycoside and alkylpolycarboxy surfactants which are well known and extensively described in the art.

The detergent composition may contain an alkyl benzene sulfonate anionic surfactant wherein the alkyl radical contains from about 10 to 16 carbon atoms in a straight or branched chain and preferably from 12 to 15 carbon atoms. Examples of suitable synthetic anionic surfactants are sodium (C4-C2o) benzene sodium and potassium sulfonates, particularly the sodium linear secondary (C? 0-C? 5) benzene sulfonates.

Other suitable anionic detergents which are optionally included in the present liquid detergent compositions are the ethoxylated and sulphated higher fatty alcohols of the formula RO (C2H40) mS03M, wherein R is a fatty alkyl of from 10 to 18 carbon atoms, m is from 2 to 6 (preferably having a value of from 1/5 to the number of carbon atoms in R), and M is a salt-forming cation solubilizer, such as an alkali metal, ammonium, or higher alkyl benzene sulfonate wherein the higher alkyl is 10 to 15 carbon atoms. The proportion of ethylene oxide in the polyethoxylated higher alkanol sulfonate is generally from 1 to 11 ethylene oxide groups and preferably from 2 to 5 moles of ethylene oxide groups per mole of anionic detergent; with three moles being more preferred, especially when the higher alkanol is 11 to 15 carbon atoms.

The most highly preferred water-soluble anionic detergent compounds are the ammonium and substituted ammonium salts (such as mono, di and tri ethanolamine), alkali metal (such as sodium and potassium) and alkaline earth metal (such as calcium and magnesium) of the higher alkylbenzene sulfonates, and the higher alkyl sulfates.

Reinforcing materials are essential components of the liquid detergent compositions of the present invention. In particular, from about 2% to about 15% of an alkali metal carbonate, such as sodium carbonate, and preferably from about 3% to about 10%, by weight.

A phosphate enhancer, and in particular an alkali metal (sodium) polyphosphate in an amount of from about 5%, to about 30%, by weight is an integral component of the present liquid detergent compositions. The amount of such polyphosphate enhancer is preferably from about 8% to about 20%.

Examples of phosphorus-containing inorganic builders include water-soluble salts, especially alkali metal pyrophosphates, orthophosphates, and polyphosphates. Specific examples of inorganic phosphate builders include sodium and potassium tripolyphosphates, phosphates and hexametaphosphates.

An aluminosilicate reinforcer of the type Zeolite A, usually hydrated can optionally be included in the compositions of the invention. The hydrated zeolites X and Y can also be useful as can be the naturally occurring zeolites which can act as detergent builders. Of the various products of Zeolite A, Zeolite 4A, a type of zeolite molecule in which the pore size is around 4 Angstroms, is also frequently preferred. This type of zeolite is well known in the art and the methods for its manufacture are described in the art such as in the patent of the United States of America number 3,114, 603.

Zeolite boosters are generally of the formula (NA20) x. (Al203) and. (Si02) z. w H20 Where x is 1, and is from 0.8 to 1.2, preferably about 1, z is from 1.5 to 3.5, preferably 2 or 3 or about 2, and w is from 9 to 9, preferably 2.5 to 6. crystal types of zeolite which may be employed herein include those described in "Zeolite Series .Molecular" by Donald Breck, published in 1974 by John Wiley & Sons, the typical commercially available zeolites being listed in Table 9.6 to pages 747-749 of the text, such table being incorporated herein by reference.

The zeolite enhancer must be a univalent cation exchange zeolite, for example, it must be an aluminosilicate of a univalent cation such as sodium, potassium, lithium (when practicable) or other alkali metal or amino. A zeolite having an alkali metal cation, especially sodium, and more preferred, as indicated in the formula shown above. The zeolites employed can be characterized as having a high exchange capacity for the calcium ion, which is usually from about 200 to 400 or more milligram equivalents of calcium carbonate hardness per gram of aluminosilicate, preferably 250 to 300 mg . eg / g., on an anhydrous zeolite base. A preferred amount of zeolite is from about 8% to about 20%.

Other components may be present in the detergent compositions to improve the properties, and in some cases, to act as diluents or fillers. Enzymes are illustrative of suitable auxiliaries to further promote the cleaning of certain stains difficult to remove from clothing or hard surfaces. Among the enzymes, proteolytic and aminolytic enzymes are more useful. Other useful auxiliaries are foaming agents, such as lauric myristic diethanolamide, when the foam is desired, and anti-foams, when desired, as dimethyl silicone fluids. Also useful are polymers, anti-redeposition agents, bleaches, fluorescent brighteners, such as stilbene brighteners, dyes such as dyes and pigments and perfumes.

Towel Removal Procedure For all evaluations of 24 samples, new hand towels (86% cotton, 15% polyester) were prepared in a washing machine that was loaded above 17 gallons set to hot wash (120 ° F), with a placement big extra, in tap water. Two wash cycles with 100 grams of Viva 2 powder detergent, Mexican, fragrance-free, a wash with water only, the extra rinse aid was in place, they were used for all washes. After three wash cycles were performed, the towels were dried in the dryer in an electric clothes dryer and placed flat for storage. All the ballast used for the tests was processed in the same way as the towels between each use.

Table 1. Base Detergent, Bl Starch granules The starch / AA granules were prepared using the Capsul starch (commercial product of National Starch). Capsul is an octenyl succinate of dextrinized waxy cornstarch. The process of dextrinization to degrade starch is what differentiates Capsul starch from other types of starches. The following procedure was used to prepare the starch / AA granules: Pre-mix 33% Capsul starch in water, at least one day in advance using a GREERCO Model No. 1L mixer. Allow the air to settle. Take the amount required for this and add fragrance oil and the melted amidoamine mixture and homogenize using a Silverson Model L4R mixer. Pour this mixture into the Armfield FT80 high-form spray dryer and spray dry at 190 ° C with 0.5 to 1.0 bar of spray pressure.

The composition of the starch granules (the amounts shown are percentages by weight) is as follows (Table 2) used to prepare the compositions shown in Table 4.

Surface Oil Content of Starch Granules / AA and Performance Comparison with Starch / Silica A study indicates that the hydrophobic additive AA significantly reduces the amount of perfume (fragrance Dinasty) to the surface of dried starch capsules 1. 24% (no AA) to 0.02% (Table 3). In contrast to AA, another study reveals that a hydrophobically modified silica (Aerosol R974, preferred additive of the prior art, patent application WO 01/05926) does not reduce the amount of surface oil thereto such as amidoamine (table 3) . The spray reduces the amount of surface oil (Dinasty perfume) in the starch granule from 0.85% (without Aerosol) to 0.77% (with Aerosol). The surface oil was measured by extraction of the particle encapsulated with hexane at room temperature and atmospheric pressure, followed by gas chromatography. Hexane extracts the fragrance oil on the surface of the particle, not the oil encapsulated within the particle.
