Description

DEVICE COMPRISING AN OXIDATIVE COMPOSITION FOR DYEING KERATINOUS FIBERS FIELD OF THE INVENTION

The present disclosure relates, in general, to personal care products, and more particularly, to devices and compositions for dyeing keratinous fibers. The present disclosure further relates to a method for dyeing keratinous fibers.

CONTEXT OF THE INVENTION

Oxidative permanent hair dye products are widely used for coloring hair and covering gray hair. Typically, these products include compositions having an oxidative dye and a developer with an oxidizing agent. However, these compositions having varying consistencies face problems as they do not always form a homogeneous mixture during mixing during application. This in turn affects the cosmetic properties of the product, as it fails to achieve uniform dyeing of the fibers.

In addition, the dye and developer are packaged separately and must be mixed before application. Among commercially available products, it is already known to use two-compartment devices in the form of a sachet to package the dye and developer separately. These products with varying rheologies often pose problems in achieving optimum spreadability on the hair.

It is desirable to achieve a creamy texture and uniform consistency in compositions. However, the use of thickeners or rheological modifiers poses a stability problem in oxidizing compositions. These stability problems can be attributed to the high reactivity of these thickeners with oxidizing agents.

In addition, the dye and developers are generally required to remain on the hair for a development time of approximately 30 to 60 minutes, for color development. It is highly desirable to reduce this development time to obtain faster coloring of the hair, especially without compromising the color uptake by the keratin fibers. The generally known oxidative compositions must have a development time of approximately 60 minutes, which makes hair dyeing a time-consuming process.

Therefore, there is a need to improve the convenience of use of these devices while providing dyeing and cosmetic properties in a short time.

In one aspect of the present disclosure, there is provided a device (100, 300 or 400) comprising a first compartment 202 and a second compartment (204), each defined in a closed envelope (102, 302 or 400a and 400b) having flexible walls, wherein said first compartment (202, 310 or 402) comprises a first composition (208) in the form of an emulsion, preferably an oil-in-water emulsion, comprising at least one oxidative dye, at least one fatty compound other than fatty acids, and at least one first surfactant; and said second compartment (204, 312 or 404) comprises a second composition (210) in the form of an emulsion, preferably an oil-in-water emulsion, comprising at least one oxidizing agent and at least one second surfactant.

Referring now to the figures, The illustrates a perspective view of an example of a device 100, according to embodiments herein. This embodiment is the preferred embodiment of the device according to the invention. As illustrated in , the device 100 is composed of a closed envelope 102, consisting of at least two flexible side walls 104a and 104b (collectively or individually referred to as 104) secured together along their peripheral edges 106, defining a sealed perimeter 108 and an interior volume. The sealed perimeter 108 has at least four ends 110a, 110b, 110c and 110d (collectively or individually referred to as 110). Preferably, the sealed perimeter 108 has a width of between 5 and 15 mm.

The device 100 may also include an opening means, for example by tearing or cutting with a pair of scissors. According to a preferred embodiment, the opening means is a pre-cut line 112, for example, from a first end 110a of the sealed perimeter 108 to a second end 110b of the sealed perimeter 108, as illustrated in . When the device 100 is torn along the pre-cut line 112, the interior volume of the device unseals and defines two distinct openings 212 and 214, a first opening 212 of a first compartment 202 and a second opening 214 of a second compartment 204. Preferably, the two openings 212 and 214 are adjacent.

In one embodiment, the device 100 may be torn along the pre-cut line 112 using a tool such as a pair of scissors. Alternatively, in another embodiment, the pre-cut line 112 may be produced by laser and may then be easily torn without a tool.

Each flexible sidewall 104a and 104b is comprised of at least one sheet of polymeric film. The sheet of polymeric film may be either a single layer or a multilayer polymeric film. The layers of polymeric film may have a different structure.

The length of the sides 104a and 104b preferably ranges from 100 to 200 mm, and more preferably from 120 to 160 mm.

The width of the sides 104a and 104b preferably ranges from 100 to 200 mm, and more preferably from 120 to 200 mm.

There illustrates a front view of the device of the . There illustrates that the pre-cut line 112 begins at the first end 110a of the sealed perimeter 108 and ends at the second end 110b of the sealed perimeter 108.

There illustrates a schematic view of the device 100 in an open state. The open state refers to a state where the interior volume of the device 100 is unsealed by tearing a portion of the device 100 along the pre-cut line 112. The interior volume of the device 100 is divided into at least two distinct compartments 202 and 204, separated from each other by at least one interior wall 206.

According to the present invention, at least one of the compartments 202 contains a first composition 208, and the second compartment 204 contains a second composition 210.

In other words, the first compartment 202 containing the first composition 208 is separated from the second compartment 204 containing the second composition 210 by the inner wall 206. The first composition 208 and the second composition 210 are therefore contained in two different compartments 202 and 204 and cannot be mixed.

Preferably, the device 100 is divided into two separate compartments 202 and 204.

According to this embodiment, the two compartments 202 and 204 are joined by a wall, preferably the inner wall 206.

The inner wall 206, according to the present invention, is included in the interior volume of the closed envelope 102. The inner wall 206 has at least four edges. Each of the four edges of the inner wall 206 is connected to at least one end 110 of the sealed perimeter 108. For example, a first edge of the inner wall 206 may be connected to the first end 110a, a second edge of the inner wall 206 may be connected to the second end 110b, a third edge of the inner wall 206 is connected to the third end 110c, and a fourth edge of the inner wall 206 is connected to the fourth end 110d.

The terms "seal" or "perimeter sealed" as used herein refer to a permanent bond between two sheets of polymeric film or between two parts of a sheet folded over itself. This sealing may be achieved by fusing and/or blending the two sheets or parts together. In other words, the seal between the two sheets or parts cannot be opened without damaging the walls formed by the two sheets or parts. The edge sealing may be achieved by methods that are generally known and clear to those skilled in the art. The first and second compositions may be loaded into the first and second compartments, respectively, by methods generally known in the art. Various techniques and equipment are generally known in the art for sealing, filling and otherwise packaging or manufacturing devices, pouches, etc. that may be used to make the various embodiments herein.

The inner wall 206 ensures impermeability between the first compartment 202 and the second compartment 204, preventing the first composition 208 contained in the first compartment 202 from mixing with the second composition 210 contained in the second compartment 204.

In the open state, when a user applies pressure to the closed envelope 102, the two compartments 202 and 204 allow the discharge of the first composition 208 through the first opening 212 and the second composition 210 separately, through the second opening 214, preferably simultaneously and/or at a similar speed.

There illustrates a perspective view of a second embodiment of a device 300, according to the invention. As illustrated in , the device 300 is composed of a closed envelope 302, consisting of at least two flexible side walls 304a and 304b (collectively or individually referred to as 304) secured together along their peripheral edges 306, defining a sealed perimeter 308 and an interior volume. The interior volume is divided into at least two distinct compartments 310 and 312, separated from each other by at least one seal 314. According to the present invention, at least one of the compartments 310 contains the first composition 208, and the second compartment 312 contains the second composition 210.

In other words, the first compartment 310 containing the first composition 208 is separated from the second compartment 312 containing the second composition 210 by the seal 314. The seal 314 may be formed by sealing the flexible sidewalls 304a and 304b together. The flexible sidewalls 304a and 304b may be sealed together, for example by a heat or ultrasonic process.

The first composition 208 and the second composition 210 are therefore contained in two different compartments 310 and 312 and cannot be mixed.

Preferably, the device 300 is divided into two separate compartments 310 and 312.

The sealed perimeter 308 has at least four ends 316a, 316b, 316c, and 316d (collectively or individually referred to as 316). In an exemplary embodiment, the sealed perimeter 308 may have a width of between 5 and 15 mm.

The seal 314, according to the present invention, is included in the interior volume of the closed envelope 302. Each of the two ends of the seal 314 is connected to at least one end 316 of the sealed perimeter 308. As illustrated in Figure 1, one of the ends of the seal 314 is connected to the first end 316a, while the other end of the seal 314 is connected to the second end 316c of the sealed perimeter 308.

The device 300 may also include an opening means for each compartment 310 and 312. According to a preferred embodiment, the opening means comprises a first pre-cut line 318, for example, from a first end 316a of the sealed perimeter 308 to a second end 316b of the sealed perimeter 308, for the first compartment 310 as illustrated in FIG. . Further, the opening means comprises a second pre-cut line 320, for example, from a first end 316a of the sealed perimeter 308 to a second end 316d of the sealed perimeter 308, for the second compartment 312 as illustrated in FIG. . When the device 300 is torn along the pre-cut lines 318 and 320, the interior volume of the device becomes unsealed.

In one embodiment, the device 300 may be torn along the pre-cut lines 318 and 320 using a tool such as a pair of scissors. Alternatively, in another embodiment, the pre-cut lines 318 and 320 may be laser-produced and may then be easily torn without a tool. The first compartment 310 may be opened by tearing a portion of the device 300 along the first pre-cut line 318 and the second compartment 312 may be opened by tearing a portion of the device 300 along the second pre-cut line 320. Accordingly, the first compartment 310 and the second compartment 312 may be opened separately.

There illustrates a perspective view of the apparatus 300 when the apparatus 300 is folded along the seal 314. When the apparatus 300 is folded along the seal 314, a consumer can unseal the interior volume by tearing a portion of the apparatus 300 along the pre-cut lines 318 and 320 together. Further, when a consumer applies pressure to the closed envelope 302 and when the interior volume of the device 300 is unsealed, the two compartments 310 and 312 allow the discharge of the first composition 208 and the second composition 210 separately, preferably simultaneously and/or at a similar speed. Preferably, the device can be folded along the seal 314 before unsealing the interior volume, in order to facilitate the unsealing and discharge of the compositions. Therefore, the device 300 facilitates the unsealing of the interior volume of the device 300 and the discharge of the first composition 208 and the second composition 210.

There illustrates a perspective view of a third embodiment of a device 400. As illustrated in , the device 400 is composed of two separate closed envelopes 400a and 400b. One closed envelope 400a defines a first compartment 402 and another closed envelope 400b defines a second compartment 404. According to the third embodiment, the two compartments 402 and 404 are not joined together. According to the present invention, at least one of the compartments 402 contains the first composition 208, and the second compartment 404 contains the second composition 210. In one embodiment, the first compartment is defined in a first sachet and the second compartment is defined in a second sachet, distinct from the first sachet.

Each closed envelope 400a and 400b may include an opening means. According to a preferred embodiment, the opening means includes a pre-cut line 406a and 406b as illustrated in . When the closed envelope 400a is torn along the pre-cut line 406a, the first composition 208 can be released from the device 400 by applying pressure to the closed envelope 400a. When the closed envelope 400b is torn along the pre-cut line 406b, the second composition 210 can be released from the device 400 by applying pressure to the closed envelope 400b. The pre-cut lines 406a and 406b can be similar to the pre-cut lines 318 and 320.

Therefore, in one embodiment, the device (100, 300 or 400) comprises the first compartment (202) and a second compartment (204) each defined in a closed envelope (102, 302 or 400a and 400b, respectively) having flexible walls.

According to a preferred embodiment, the closed envelope 102, as well as the closed envelopes 302, 400a and 400b, are made of at least one sheet of polymeric film folded on itself and sealed on its corresponding peripheral edges 106, 306 and so on. In other words, according to this particular embodiment, the two flexible side walls 104a and 104b are made of the same sheet of polymeric film, which can be either a single-layer or multi-layer polymeric film.

Preferably, the polymeric film sheet is a multilayer polymeric film comprising at least two different or identical polymeric film layers. Thus, the polymeric film sheet has a laminated structure and the polymeric film layers are superimposed on each other.

Composition 3 (not an emulsion) includes 0.06% by weight of tetrasodium etidronate, 0.03% by weight of sodium salicylate, 6% by weight of hydrogen peroxide, 0.04% by weight of tetrasodium pyrophosphate, 2.28% by weight of cetearyl alcohol, 0.85% by weight of trideceth-2 carboxamide MEA, 0.5% by weight of glycerin, 0.57% by weight of ceteareth-25 and to make up to 100% by weight of water.

Results: The results of the viscosity test are shown schematically in Table 4. The viscosity of Composition 2 was found to be different from that of Composition 3. The difference in viscosities of Compositions 3 and 2 was found to facilitate improved cosmetic properties and user convenience, according to the present embodiment. It was observed that the distribution of Composition 1 and Composition 3 was uneven due to the difference in viscosities thereby affecting the cosmetic properties and user convenience. This difference and improved properties can be attributed to the carefully selected combination of ingredients in Composition 2 within the specified weight ranges as disclosed herein. For example, Composition 2 includes a combination of surfactants such as ceteareth-33, and ceteareth-60 myristyl glycol which was not present in Composition 3. Furthermore, Composition 3 was not an emulsion unlike Composition 2 as disclosed herein.

Furthermore, when comparing the viscosities of the combined compositions, i.e., Blends 1 and 2, it was observed that Blend 1 had a creamy consistency as compared to Blend 2, thereby contributing to a better user feel, and improved and uniform spreadability of the mixture/product on the keratinous fibres. This also resulted in a difference in the colour delivery, as the product is intended to be applied by hand, i.e. without the need for a brush or bowl. The creamy consistency made it possible to pick up the composition by hand for mixing and application on the keratinous fibres.

Assessment of coloring.

The coloration obtained by mixture 1 and mixture 2 (see example 3) was evaluated using the L system^*, has^*, b^*. Assessment of color can be done visually or read on a spectrocolorimeter (such as Minolta CM3600d, illuminant D65, angle 10°, SCI values) for colorimetric measurements of L^*, has^*, b^*. In this system L^*, has^*, b^*, L^*represents the color intensity, a^*indicates the green/red color axis and b^*indicates the blue/yellow color axis. The lower the value of L, the darker or more intense the color. The higher the value of a^*is high, the redder the shade; the higher the value of b^{* East}the higher the value, the more yellow the shade. The variation in coloration between colored strands of natural white hair that are not treated (control) and after treatment or coloring is defined by ΔE^*, corresponding to the color uptake on keratinous fibers, according to the following equation:

In this equation, L ^* , a ^* and b ^* represent the values measured after dyeing of natural hair comprising 90% white hair and L ₀ ^* , a ₀ ^* and b ₀ ^* represent the values measured for untreated natural hair comprising 90% white hair.

The higher the ΔE value, the greater the color difference between the control strands and the dyed strands and the greater the color uptake.

Results: The results of the coloring test are shown schematically in Table 5. A clear difference is observed on the strands with the 2 mixtures Mixture 1 and Mixture 2. It was found that Mixture 1, having a ΔE of 43.99, had better color uptake on the keratinous fibers compared to Mixture 2, having a ΔE of 40.39 . The higher color uptake was obtained thanks to Mixture 1, i.e. the product according to embodiments herein, with a reduced pause time. In addition, the color intensity was better with Mixture 1 (L* significantly smaller for Mixture 1).
