METHOD OF APPLYING A COMPOSITION

BACKGROUND OF THE INVENTION

(1) Field of the Invention

[0001] The invention relates to a method of applying a composition.

(2) Description of Related Art

[0002] Many industries and markets thrive on being able to deliver multiple performance products based on mixtures of several components, with each component having a performance and compatibility profile, which can lend that component to properties that are important to or desirable in certain final product formulations. In methods of applying compositions some desirable properties can be derived from the use of cyclic siloxanes in the formulation. Although cyclic siloxanes can provide some of these desired properties, they are low viscosity, highly flowable liquids. Thus, they are not easily held in a formulation, preferring rather to separate and flow out of a given container or flow uncontrollably across the skin and/or other substrate when used in a specific application.

[0003] Cyclic siloxanes have limitations in terms of their performance and compatibility profile. A desired performance and/or compatibility profile possessing the various desirable properties is not always achievable by using a cyclic siloxane. Certain applications can require different properties that cannot be met by the use of cyclic siloxanes. [0004] For example, one of the disadvantages of the current state of the art is that ^■ many spray able formulations suffer from clogging of the spraying system, poor or coarse droplet formation and uneven or poor coverage with too much run-down on a non- horizontal surface. Run-down can, for example, lead to a disadvantageous distribution of benefit ingredients delivered onto any substrate, transporting those ingredients to areas where they might be undesired and/or leading to an uneven distribution where they are desired. Also, clogging of spraying nozzles can impose too much mechanical stress and lead to early wear down of spraying systems. Coarse droplets will lead to uneven actives distribution. The resulting poor coverage will in turn lead to lower performing attributes. Often ethanol is used as a dispersant, however, in certain applications such as personal care it suffers from a concomitant drying effect that can cause skin flakiness and irritation. Therefore there exists a need for a sprayable formulation without the disadvantages mentioned above.

Often here, the kinetic energy of the flowing medium is increased at the expense of a certain pressure energy of the fluid before passing through the nozzle.

[0030] In one further specific embodiment applying trisiloxane-containing composition further comprises spraying specifically from about 0.001 milliliters to about SO milliliters per application of spray, more specifically from about 0.01 milliliters to about 5 milliliters per application of spray and most specifically from about 0.1 milliliters to about 0.5 milliliters per application of spray.

[0046] In another embodiment there is provided a method of manufacturing the foregoing personal care applications comprises combining the above-described trisiloxane-containing composition with a personal care ingredient such as is known to those skilled in the art. Some non-limiting examples of personal care ingredients are described in U.S. Patent Application No.11/274,450 filed on November 15, 2005 the contents of which are incorporated herein in their entirety.

[0047] In yet still even another embodiment the disclosed personal care compositions may exhibit a variety of advantages in personal care applications. Some such non-limiting advantages are less run-down, alone or in combination with any active ingredient. Other properties of each of the personal care applications will vary depending on the characteristics of the particular trisiloxane(s) chosen, for example the type(s) of hydrocarbyl radicals present, the presence and type(s) of any substitution(s) on the silicone backbone or on the side chain(s), the molecular weight of the trisiloxane(s), and like considerations,, as well as the remaining components of the sprayable personal care application. The desired properties of specific personal care applications can be specifically determined by those skilled in the art. Some specific examples of properties provided by use of the trisiloxanes herein may include reduced tackiness, enhanced spreadability, fast drying, less over-wetting, improved homogeneity, enhanced organic compatibility, improved skin feel, controlled actives delivery, improved shine, and/or reduced skin irritation. Test panels can be used to objectively determine the reduced tackiness, improved homogeneity, enhanced organic compatibility and improved skin feel. The enhanced spreadability may be determined by measuring the coefficient of friction in a sample of the personal care composition. Skin irritation may be determined by measuring the onset of erythema. Sunscreens are evaluated according to their ability to slow erythema or sunburn resulting from exposure to ultraviolet light. Shine may be determined by measuring refractive index using a gloss meter.

[0048] In yet a further embodiment herein, there is provided a personal care formulation, such as those described above, comprising silicone gel produced by any process described in U.S. Patent Application No. 11/274,450 filed on November 15, 2005 the contents of which are incorporated herein in their entirety.

[0049] The examples below are given for the purpose of illustrating the invention of the instant case. They are not being given for any purpose of setting limitations on the embodiments described herein. All weights are weight percent based on the total weight of trisiloxane-containing composition unless stated otherwise.

EXAMPLES

[0050] Preparation of the following trisiloxane-containing compositions in Table

Octylsalicylate 0 0 20.00 20.00 [0051] When spraying Comparative Example I and Example I onto surface,

Comparative Example I shows clear signs of run-down, while Example I does not, as exemplified in FIGURES I and II in the drawings section below. Comparative Example I has a run-down on the above-identified scale of 2. Example I has run-down on the above-identified scale of 0.

[0052] As can be clearly seen, the formula with cyclopentasiloxane starts to rundown, while the formula with ETS stays in place. Here in both cases, a well primed pump spraying system was used once and applied from 10.16 centimeters away from the substrate which was notebook paper.

[0053] In order to accommodate for the possibility that the ETS containing formulations do not just not run down because they deposit less materials on the top of the substrate surface, and in order to eliminate the effect of variations from spray to spray, the following control experiments were run:

[0054] From 10.16 centimeters away, the above experiment was repeated, aiming at lined and previously carefully weighed out notepad paper. Five sprays of each of the formulations Comparative Example I & Example I were delivered, and the so delivered mass of material was obtained by gravimetry:

[0055] Comparative Example I: 0.581 grams (g) was deposited with five sprays

=> 0.58 lg/5 = 0.1162g per spray deposited. Since a run-down phenomena could also depend on the volume deposited, these results were corrected for the density of the formula, which was determined to be 0.9777g/rnl, using a Mettler/Paar DMA46 Calculating Digital Density Meter =o 0.1162g/0.9777g/ml = 0.1189ml per spray deposited.

[0056] Example I: 0.622g was deposited with five sprays => 0.622g/5 = 0.1244g per spray deposited. With the density determined as described above, the following volume was deposited: 0.1244g/0.9107g/ml = 0.1366ml per spray deposited. [0057] In addition, all experiments were carried out with different spray pumps of the same type (Qosmedix Corporation, Edgewood, New York, United States white spray mister with clear overcap Model #29717, spray pump made of polypropylene and bottle is made of polyvinylchloride) to eliminate any possible effect of the pump itself.

[0058] Clearly, as can be seen from the above, the ETS formulas do not deposit less than the cyclopentasiloxane formulas, hence the no-run-down effect is genuinely due to the beneficial presence of the ETS.

[0059] Spraying Comparative Example I onto hydrated vitro-skin and measuring the resulting sun protection factor using a Labsphere UVlOOO Light Simulator yields a sun protection factor of 11, while Example I gives a sun protection factor of 13 under the same conditions.

[0060] This serves as a principal example that use of trisiloxanes disclosed herein, as exemplified but not limited to 1,1,1,3,5,5,5- heptamethyl-3-ethyltrisiloxane (ETS), delivers measureable enhanced properties in various sprayable applications.

[0061] Figures 3 and 4 in the drawings section below shows that this no-rundown-effect when using ETS is not formulation dependant, but rather a generic benefit of the ETS. Figures 3 and 4 are included to show that the ingredient ETS is the main factor responsible for the decrease in run-down in the Examples over the Comparative . Examples. Comparative Example II has a run-down on the above-identified scale of 3. Example II has run-down on the above-identified scale of 0. All the examples and comparative examples herein were sprayed using a well-primed spray bottle. Comparative Example II and Example II were applied from the same distance as Example I and Comparative Example I. All of the data in Table 1 was weight percent data based on the total weight of the trisiloxane-containing composition in each of the respective examples and comparative examples. Example II and Comparative Example π were applied using the same number of sprays as indicated in Example I and Comparative Example I.

[0062] Here once again, the formula with cyclopentasiloxane does show significant run-down, while the one with ETS stays in place. Figures 1-4 are xerographic reproductions of photographs of patterns resulting from the application of compositions within (Examples I and II) and other compositions outside (Comparative Examples I and II) the scope of the disclosure herein, said photographs being taken shortly after (1-6 seconds) application of said compositions.

[0063] While the above description comprises many specifics, these specifics should not be construed as limitations, but merely as exemplifications of specific embodiments thereof. Those skilled in the art will envision many other embodiments within the scope and spirit of the description as defined by the claims appended hereto.
