Definitions
- the present invention relates to aqueous compositions comprising vesicles having a vesicle permeability index of less than about 1.3 to facilitate the delivery of water-soluble active materials having a C log P of less than about 2.0 to surfaces being treated with the compositions.
- a number of commercialized products such as fabric softeners, hard surface cleaners, hair conditioners, agrochemical products and paints, contain active materials that are water-soluble. Oftentimes, these products contain water-soluble active materials that are intended to be deposited onto a surface being treated with the product. However, if these water-soluble materials are in a highly aqueous environment, it can be difficult to effectively deposit the water-soluble active materials onto the surface.
- a fabric softening composition is typically added to the rinse solution in a fabric laundering process, which contains a large volume of water. Once the rinse cycle is complete, the rinse solution is discarded down the drain, usually taking a large portion of the water-soluble active materials with it. Thus only a small portion of the water-soluble active materials is actually deposited on the treated fabrics.
- composition containing water-soluble active materials such that the composition can effectively deposit the water-soluble active materials to a surface being treated with the composition.
- compositions comprising:
- the present invention further relates to a process for making the present compositions comprising the steps of dispersing the dialkyl quaternary ammonium compound and the water-soluble active material in an aqueous solution to form vesicles having a vesicle permeability index of less than about 1.3.
- the present invention relates to compositions containing vesicles to facilitate the delivery of water-soluble active materials to surfaces treated with the present compositions.
- vesicle means one or more bilayers arranged in a closed, usually spherical geometry, said bilayer comprises quaternary ammonium agent as described hereinabove.
- the vesicles are preferably substantially spherical.
- the presence of vesicles in the present compositions can be detected by microscopic analysis (e.g., polarised light microscopy at a magnification of 60 ⁇ ).
- the vesicles in the present compositions have a number average size of from about 50 nm to about 20 ⁇ m, more preferably from about 100 nm to about 5 ⁇ m, most preferably from about 200 nm to about 2 ⁇ m as determined by photon correlation spectroscopy.
- the vesicles in the present compositions are generally formed by dispersing the molten dialkyl quaternary ammonium compound in hot water having a temperature above the transition temperature of the dialkyl quaternary ammonium compound. It is believed that the vesicles envelope the water-soluble active materials and then can effectively deliver these species to a surface being treated.
- the vesicles in the present compositions exhibit a particular vesicle permeability as measured according to the test method described herein.
- the vesicle permeability of the vesicles formed can be affected by the temperature and by the structure of the dialkyl quaternary ammonium compounds, more specifically by the degree of unsaturation and the presence or the absence of linking groups between the alkyl chain and the nitrogen, such as esters.
- compositions of the present invention will typically have a pH of from about 2 to about 7, preferably from about 2 to about 6, and more preferably from about 2.5 to about 5.0.
- compositions comprise a dialkyl quaternary ammonium compound having the formula: wherein R 1 and R 2 are independently C 12 to C 20 saturated alkyl chains; Y is wherein R 4 is ethyl or isopropyl; R 3 and R 5 are independently methyl, ethyl, hydroxyethyl, or hydroxypropyl; m is 1, 2, or 3; n is 1 or 2; and p is 0 or 1.
- the counterion, X ⁇ in the above compounds can be any compatible anion, preferably the anion of a strong acid, for example, chloride, bromide, methylsulfate, ethylsulfate, sulfate, nitrate and the like, more preferably chloride or methyl sulfate.
- a strong acid for example, chloride, bromide, methylsulfate, ethylsulfate, sulfate, nitrate and the like, more preferably chloride or methyl sulfate.
- Suitable dialkyl quaternary ammonium compounds of the present invention include alkylchains wherein R 1 and R 2 are C 16 or C 18 or hardened tallow or hardened palm or mixtures thereof.
- Non-limiting examples of dialkyl quaternary ammonium compounds include N,N-di(stearoyl-oxy-ethyl)-N,N-dimethyl ammonium chloride; N-stearyl-N-(stearoyl-oxy-ethyl)-N,N-dimethyl ammonium chloride; N,N-di(stearoyl-oxy-ethyl)-N-methyl, N-(2-hydroxyethyl) ammonium methylsulfate; and 1,2-distearoyloxy-3-N,N,N-trimethylammoniumpropane chloride.
- the dialkyl quaternary ammonium compound is typically present in the compositions of the invention at a level of from about 1% to about 30%, preferably from about 2% to about 25%, and more preferably from about 3% to about 20%, by weight of the composition.
- the present compositions further comprise a water-soluble active material.
- the degree of hydrophilicity of an active material in the present compositions can be correlated with its octanol/water partitioning coefficient P.
- the octanol/water partitioning coefficient of an active material is the ratio between its equilibrium concentration in octanol and in water.
- An active material with a greater partitioning coefficient P is more hydrophobic.
- an active material with a smaller partitioning coefficient P is more hydrophilic. Since the partitioning coefficients of active materials normally have high values, they are more conveniently given in the form of their logarithm to the base 10, log P.
- the log P of many materials has been reported; for example, the Pomona 92 database, available from Daylight Chemical Information Systems, Inc. (Daylog CIS), Irvine, Calif., contains many, along with citations to the original literature. However, the log P values are most conveniently calculated by the “C log P” program (calculation of hydrophobicities as log P (oil/water)) version 4.01, available from Daylight Chemical Information Systems Inc of Irvine Calif., USA.

- the vesicular compositions of the present invention are made by dispersing a molten dialkyl quaternary ammonium compound in water having a temperature above the transition temperature of the dialkyl quaternary ammonium compound under mechanical shear.
- the water temperature is kept above the transition temperature during the dispersion process to ensure the formation of a vesicular dispersion of the dialkyl quaternary ammonium compound.
- the water-soluble active material to be delivered to the treated surface is preferably added to the hot water prior to the addition of the molten dialkyl quaternary ammonium compound.
- the water-soluble active material is added together with or after the addition of the dialkyl quaternary ammonium compound to the hot dispersion, and the dispersion is kept hot for a sufficient time under mechanical shear to ensure the water-soluble active material is partioned into the intravesicular water domain.
- the vesicular dispersion is subsequently cooled to ambient temperature, thus ensuring effective encapsulation of the water-soluble active material in the vesicles.
- a NMR diffusometry method provides information about the distances diffused by species in a component resolved manner.
- the method allows for determination of the diffusion rates of all components in the mixture. Due to the very high signal-to-noise of water, water is used to act as the probe for the permeability though the vesicle membranes.
- the component resolved signal decay in the NMR diffusometry experiment is impacted by the presence of barriers. In a concentrated mixture of vesicles the signal contains, roughly, two different types of water; water trapped inside and water outside the vesicles. Due to the chemical exchange, the fraction of water inside or outside depends strongly on the allowed diffusion time.
- the ratio of the apparent volume fraction inside vesicles at a shorter diffusion time (e.g. 10 ms) over the apparent volume fraction at a longer diffusion time (e.g. 80 ms) gives therefore a measure of the vesicle permeability.
- the vesicles in the present compositions have a particular permeability index, P, that is determined according to the following test method.
- Water diffusion inside and outside the vesicles is measured with Pulsed Field Gradient (“PFG”) NMR and evaluated according to the methods described in “Colloids and Surfaces A, Diffusion of water in multilamellar vesicles of dialkyl and dialkyl ester ammonium surfactants”, Cecilia Groth, Johanna Bender and Magnus Nydén (in press). Diffusion measurements are performed at 20° C. Diffusion times range from 10 ms up to 1 s using 5 different values logarithmically spaced between 10 and 80 ms.
- the pulsed field gradient strength is varied between 0.005 to 3.74 T/m with 45 linearly spaced gradient strengths spaced in-between (47 in total).
- the permeability Index, P can then be calculated as P vw app (10 ms)/P vw app (80 ms).
- compositions of the present invention are provided in the following table as Examples 1-11.
- the compositions can be used as fabric softening compositions added during the rinse cycle of a laundering process to improve the softness and freshness of the fabrics being laundered.
- PRM1 beta gamma hexenol
- PRM2 coumarin
- PRM3 ethyl acetoacetate
- PRM4 2 parts benzaldehyde, 2 parts beta gamma hexenol, 10 parts coumarin, 10 parts ethyl acetoacetate and 40 parts phenyl ethyl alcohol.
- composition of Example 11 is a preferred composition of the present invention wherein the composition is made by adding PRM 4 to the hot product during formation of the vesicular dispersion, whereas the compositions of Examples 12 and 13 are made by adding PRM 4 to the cold product after the vesicular dispersion is formed.
- Every maximum numerical limitation given throughout this specification includes every lower numerical limitation, as if such lower numerical limitations were expressly written herein. Every minimum numerical limitation given throughout this specification includes every higher numerical limitation, as if such higher numerical limitations were expressly written herein. Every numerical range given throughout this specification includes every narrower numerical range that falls within such broader numerical range, as if such narrower numerical ranges were all expressly written herein.
