Description

PERSONAL CARE SPRAY COMPOSITIONS AND METHODS COMPRISING

TRANS-l-CHLORO-3,3,3-TRIFLUOROPROPENE

BACKGROUND

[0001] Many personal care products are applied in the form of a spray, including hair sprays, dry shampoos, deodorants and antiperspirants. Such products generally comprise an active component or components that provide the intended function when it applied to the skin, hair or scalp. Such products also generally include carriers which solvate, disperse or emulsify the active ingredient so that it can be effectively transported from its container to the surface of the user to be treated. In many applications the container includes a propellant or other means to propel the active/carrier to the surface to be treated in the form of a spray. As a result of the application of the composition in the intended manner, the active component becomes operative upon or in association with the removal, usually by evaporation, of the solvent or carrier.

[0002] Generally, it is desired for such personal care products to deliver the active ingredient in the form of a well-formed spray that dries quickly from the skin, hair or scalp of the user. It has also become increasing desirable for the carrier to have a relatively small negative environmental impact, such as having a low ozone depletion potential, a low global warming potential and low volatile organics content. In addition to favorable environmental properties, the carrier preferably also has, depending on the particular application, an inertness with respect to the active ingredient(s), low toxicity and low flammability, among other properties.

[0003] One carrier that has heretofore been commonly used in such applications is ethanol. Applicants have come to appreciate that important and unexpected improvements in the performance of such products can be achieved by the use of novel carrier in a spray-applied personal care formulation that is capable of providing a well-formed spray that is quick drying and environmentally friendly.

SUMMARY

[0007] The present invention provides compositions, methods and products which comprise one or more active components and which utilize as a carrier trans-l-chloro-3,3,3- trifluoropropene (trans-HCFO-1233zd).

[0008] The present invention includes personal care products comprising:

a) container having a nozzle or opening for releasing the contents thereof;

b) a personal care formulation in the container comprising:

(i) an active component for affecting the personal care of the user; and

(ii) a carrier for the active component, said carrier comprising at least about 50% by weight based on the weight of the carrier of trans-HCFO-1233zd and optionally a co-carrier in amounts of up to about 50% by weight based on the weight of the carrier.

[0009] The present invention also includes a personal care formulation comprising:

(i) an active component for affecting the personal care of a user of the formulation; and

[0010] The present invention includes a method of applying a personal care product to a user comprising:

a) providing a container having a opening or nozzle for expelling or releasing at least a portion of contents therefrom;

b) including in said container a personal care formulation comprising:

(i) an active component for affecting the personal care of the user; and (ii) a carrier for the active component, said carrier comprising at least about 50% by weight of trans-HCFO-1233zd based on the weight of the carrier and optionally a co-carrier in amounts of up to about 50% by weight based on the weight of the carrier; and

c) removing at least a portion of said personal care formulation from the container and applying it onto the area of the user to receive the personal care product.

[0011] Applicants have unexpectedly found that the preferred compositions, methods, and products of the present invention provide not only highly favorable and desirable environmental properties, including preferably low GWP, low ODP and/or low VOC, the trans- HCFO-1233zd described herein for use as the carrier possess a desirable but difficult to achieve mosaic of other properties, including providing the formulation, methods and products with a quick drying ability and at the same time providing one or more of the following difficult to achieve properties in combination with the quick drying effect:

- substantial inertness with respect to the active ingredient(s),

- low toxicity,

- low flammability,

- good spray forming ability,

- good ability to uniformly carry the active component in the amounts required.

[0012] Applicants have unexpectedly found that the preferred compositions, products and methods of the present invention have the unexpected advantage of being quick drying, that is, the carrier is readily and quickly removed after application to the user by evaporation. In highly preferred embodiments, the formulations, products and methods are quick-drying and self drying. As used herein, the term“self-drying” refers to the removal of the carrier after it is applied by simply being exposed to the body of the user in the environment of use without the introduction of any separate drying source, and preferably with little or no additional steps after the spraying step. Thus, in preferred compositions, methods and products, the time required to dry the formulation is relatively low and requires relatively little, and preferably no additional energy after the application step.

[0013] The present invention includes a sprayable leave-on treatment product comprising: a) container having a spray nozzle for expelling the contents thereof; b) a personal care formulation in the container comprising:

(i) an active component for affecting the cleanliness, and/or appearance and/or feel of the hair and/or scalp and/skin of the user;

(ii) a carrier for the active component, said carrier comprising at least about 50% by weight based on the weight of the carrier of trans-HCFO-1233zd and optionally a co-carrier in amounts of up to about 50% by weight based on the weight of the carrier; and

iii) propellant in the container for propelling at least a portion of said personal care formulation from said container through said spray nozzle.

As used here, the term“leave-on treatment” refers to products and formulations which are applied to the user and are not then intended to be rinsed or washed off as part of the treatment process. Such materials are also sometimes referred to in the industry as“dry” compositions or products since a water wash or rinse is not required. In preferred embodiments according to this paragraph, the propellant comprises, consists essentially of, or consists of one or more of transl234ze, HFC-152a, dimethyl ether (DME), a hydrocarbon propellant, including blends of hydrocarbon propellants, such as blends of propane, isobutane and/or butane (an example of such a blend being A46) and combinations of two or more of these.

[0014] The present invention also includes a sprayable leave-on treatment formulation comprising:

(i) an active component affecting the cleanliness, and/or appearance and/or feel of the hair and/or scalp and/or skin of the user; and

(ii) a carrier for the active component, said carrier comprising at least about 50% by weight of trans-HCFO-1233zd based on the weight of the carrier and optionally a co- carrier in amounts of up to about 50% by weight based on the weight of the carrier.

EXAMPLES

Example 1 [0065] Unless otherwise noted, the quantity indications below are understood as percentages by weight.

[0066] The formulas indicated in Table 1 below are provided by mixing the indicated components, with the exception of the propellant, and introducing them into an aerosol spray can. The aerosol cans were sealed with the valve/nozzel arrangement, and then the indicated propellant was added through the valve. The formulation was then applied to a sheet of wax paper by spraying the formulation from the can for one (1) second while the nozzle is held 6 inches from the paper under ambient conditions (about 73°F and 66 relative humidity with a 61Έ dew point). The time from the completion of the one second spray to the paper is dry is recorded as drying time. For this purpose of determining when the paper is dry according to this measurement, the process is video recorded and the time to disappearance of a wet spot is determined and checked against the weight of the paper gain corresponding to a plateau in the weight gain of the paper to determine dry time. In other words, the paper is considered dry when the carrier portion of the formulation has substantially fully evaporated from the paper.

Example 2

[0068] Example 1 is repeated except that the propellant A46 (consisting of 15.2% propane and 84.8% isobutane producing a vapor pressure of 46 psig at 70°F) was used instead of a propellant consisting of transl234ze. The formulations tested and the results obtained are reported in Table 2 below:

[0069] TABLE 2

[0070] The results from Examples 1 and 2 are plotted in the chart provided as

Figure 2.

[0071] As can be seen from the results of the test work reported in Examples 1 and 2 and illustrated in Figure 2, the dry times for formulations in which ethanol is 100% of the carrier produce dry times of from about 300 seconds to about 450 seconds. Importantly, using the same concentration of carrier in the formulation but with a carrier that is 75% ethanol and 25% transl233zd produces a drying time improvement of from about 10 to about 25 relative percent. Importantly and surprisingly, a more substantial improvement in drying time occurs as the amount of transl233zd in the carrier increases above 25% to about 75%, with drying times exhibiting the highest level of improvement with concentrations of transl233zd in the carrier of from about 50% to 100%. For example, when A46 is the propellant, the drying time is reduced to about 50 seconds or less when the concentration of transl233zd is about 50% or greater, which is an improvement 8 times more significant that that achieved when the concentration of transl233zd in increases from zero to 25%. A similar dramatic and unexpected relative improvement occurs with transl234ze as the propellant.

Example 3

[0072] Unless otherwise noted, the quantity indications below' are understood as percentages by weight.

[0073] The formulas indicated in Table 3 below are provided by mixing the indicated components, with the exception of the propellant, and introducing them into an aerosol spray can. The aerosol cans were sealed with the valve/nozzle arrangement, and then the indicated propellant was added through the valve. The formulation was then applied to a sheet of black construction paper by spraying the formulation from the can for five (5) seconds while the nozzle is held 12 inches from the paper under ambient conditions (about 73°F and 66 relative humidity with a 61 F dew point). Photographs of the spray pattern that is created with each formulation are provided in Figure 3.

TABLE 3

[0074] The results of Example 3 demonstrate a further unexpected advantage of the preferred formulations, products and methods of the present invention. In particular, it can be seen from Figure 3 that the use of carrier consisting of ethanol and carrier consisting of 75% ethanol and 25% transl 233zd each produces a spray pattern that is much wetter than desirable for many applications, as can be seen by the high level of dripping from the formulation sprayed onto the paper. Unexpectedly, a 50/50 wt% blend of 1233zd and ethanol produces a highly desirable wide, uniformly distributed spray pattern of starch on the paper with no dripping. Similarly, results are shown for carriers having 25% ethanol and 75% transl233zd and 10% ethanol and 90% transl233zd.
