PRIORITY AND RELATED APPLICATION

[0001] This patent application claims benefit of priority to United States Patent Application Serial No. 16/668,494, filed on October 30, 2019, entitled " DRIP-FREE CLEANSING MASK WITH ENHANCED ACTIVE DEPOSITION," the disclosure of which is incorporated by reference as if fully rewritten herein.

FIELD OF THE DISCLOSURE

[0002] The present disclosure relates to a cleansing mask composition. More particularly, the disclosure relates to a drip-free cleansing mask with enhanced active composition.

BACKGROUND

[0003] Cosmetic cleansing and shampoo formulations are valued by a wide range of consumers. They often contain sulfate-based surfactants which facilitate the cleansing process by decreasing: the surface tension of water and thus allowing water to adhere to the dirt on the skin or hair. However, these products, due to the presence of surfactant in the composition, have a tendency of making the skin or hair too dry and, therefore, consumers prefer to use products that don’t contain sulfate-base surfactants. But, sulfate-free cleansers are difficult to thicken sufficiently to afford the good sensory properties. Such cleansers do not remain on the hair or skin during and/or after application, and can drip and run into the user’s eyes, mouth, ears or nasal passages. This lends to an unpleasant consumer experience. Currently two approaches are employed to thicken sulfate-free cleanser formulas. One involves using high levels of non-sulfate surfactants to benefit from the self-assembling properties of such ingredients. This approach is most common, but it is also costly. The second approach involves using high levels of rheology modifiers; however, these components can adversely impact the properties of the composition by decreasing the ease of distribution of the composition. [0004] Therefore, it is an object of the present disclosure to create a cleansing product that provides not only an aesthetically appealing attribute upon application, but also advantageously remains in place on the keratinous surface to which it is applied so that it does not drip or run. As mentioned before, the cleansing compositions are easy to apply, drip free, and are also unique in their ability to have a good deposition of skin active ingredients.

DETAILED DESCRIPTION OF THE DISCLOSURE

[0020] The instant disclosure relates to compositions for cleansing the skin.

[0021] The cleansing mask compositions of the instant disclosure, in their broadest sense, typically include the following: a) from about 0.4 to 9 wt.% of a first thickener chosen from non-acrylate base rheology modifier; b) from about 0.2 to about 2 wt.% of a second thickener chosen from acrylic- or acrylate based thickeners; c) from about 2 to 25 wt.% of at least one surfactant; d) a skin care active ingredient; and wherein the composition has a loss modulus absolute value (G”) and a storage modulus absolute value (G’); wherein the weight percentages are based on the total weight of the cleansing mask composition.

[0022] The cleansing masks compositions of the instant disclosure exhibit a surprisingly drip free behavior once applied on the skin.

[0023] Without being bound by theory, it is believed that the specific combination describes in the present disclosure participates in the no dripping behavior as well as in the deposition of the skin active ingredients on the skin. Additionally, without wishing to be bound by theory, it is believed that the deposition of the salicylic acid helps oily skin and/or acne.

[0024] As used herein, the term “deposition” means that the skin active ingredient is building up onto the skin after application, and remains after rinsing away the product.

[0025] As used herein, the term “no drip” or “drip free” means that the composition once applied on the skin does not run off the surface of the skin where the cleansing mask is applied.

[0026] As used herein, the term “essentially sulfate free” means that, while it is preferable that no sulfate is present in the compositions of the invention, it is possible to have very small amounts of sulfate in the compositions, provided that these amounts do not materially affect the advantageous properties of the composition. In particular, “essentially sulfate-free anionic surfactant” means that no traditional sulfate-based anionic surfactants are used in the composition and that the surfactant does not contribute sulfate to the composition. Most preferably, the compositions contain no sulfate. To the extent any sulfate is present in the compositions, it is present at an amount of less than about 2.0% by weight, typically less than about 1.5% by weight, typically less than about 1.0% by weight, typically less than about 0.5% by weight, more typically less than about 0.1% by weight, based on the total weight of the composition. To the extent present, the sulfates in such compositions are typically contributed by components other than the anionic surfactant.

[0027] Thickeners

[0028] Non-Acrylates based Rheology modifier

[0029] The composition includes a non-acrylate based rheology modifier. The non-acrylates based rheology modifier exhibits a unique rheology in which the storage modulus and loss modulus are inverted relative to a traditional oil-in-water emulsion, i.e. the loss modulus is greater than the storage modulus. In compositions exhibiting both storage and loss moduli, the storage modulus measures elasticity (i.e., stored deformation energy) and partly describes the solid like behavior and the loss modulus measures viscosity (i.e., deformation energy lost during flow) and partly describes the fluid-like behavior. Systems in which the loss modulus greater than the storage modulus exhibit fluid-like behavior. In an embodiment, the composition exhibits an inverted storage and loss moduli, which do not cross during storage or use, allowing the composition to exhibit fluid-like behavior at essentially all times.

[0030] The rheology modifiers are typically in the form of an aqueous gel. Although the gel is solid in appearance the higher loss modulus allows the gel to exhibit fluid like behavior and recovery from mechanical stress.

[0031] In various embodiments, the rheology modifiers may be

- nonionic associative polyurethane polyethers:

Preferably, the nonionic associative polyurethane polyethers comprise at least two lipophilic hydrocarbon-based chains containing from 6 to 30 carbon atoms which are separated by a hydrophilic block, it being possible for the hydrocarbon-based chains to be side chains or chains at the end of the hydrophilic block. In particular, it is possible for one or more side chains to be envisaged. In addition, the polymer may comprise a hydrocarbon-based chain at one end or at both ends of a hydrophilic block.

The polyurethane polyethers may be multiblock, in particular in triblock form. The hydrophobic blocks may be at each end of the chain (for example: triblock copolymer having a hydrophilic central block) or distributed both at the ends and in the chain (for example, multiblock copolymer). These same polymers may also be graft polymers or star polymers.

The nonionic fatty-chain polyurethane polyethers may be triblock copolymers, the hydrophilic block of which is a polyoxyethylene chain comprising from 10 to 500 and preferably from 10 to 300 oxyethylene groups.

In a first variant, use may be made of a polyurethane polyether derived from the polycondensation of:

- the polycondensate of polyethylene glycol containing 136 mol of ethylene oxide, stearyl alcohol polyoxyethylenated with 100 mol of ethylene oxide and hexamethylene diisocyanate (HDI) especially with a weight-average molecular weight (Mw) of 30000 or 40000 (INCI name: PEG-136/steareth-100/HDI copolymer), such as the product sold under the name Rheoluxe 811 or Nuvis FX 1100 (formerly Rheolate® FX 1100) by the company Elementis.

In a second variant, use may be made of a polyurethane polyether derived from the polycondensation of: (i) a polyethylene glycol comprising from 130 to 200 mol of ethylene oxide,

(ii) a monoalcohol comprising from 8 to 22 carbon atoms, especially decyl alcohol or stearyl alcohol, and

(iii) a diisocyanate containing from 6 to 20 carbon atoms, chosen especially from methylenebis(4-cyclohexyl isocyanate) (SMDI) and hexamethylene diisocyanate (HDI), and preferably SMDI.

Such polyurethane polyethers are, for example:

- a polycondensate of polyethylene glycol containing 150 or 180 mol of ethylene oxide, stearyl alcohol and methylenebis(4-cyclohexyl isocyanate)

(SMDI) (INCI name: PEG-150/stearyl alcohol/SMDI copolymer), such as the product sold at 15% by weight in a matrix of maltodextrin (4%) and water (81%) under the name Aculyn 46 by the company The Dow Chemical Company;

- a polycondensate of polyethylene glycol containing 150 or 180 mol of ethylene oxide, decyl alcohol and methylenebis(4-cyclohexyl isocyanate) (SMDI) (INCI name: PEG-150/decyl alcohol/SMDI copolymer), such as the product sold at 35% by weight in a mixture of propylene glycol (39%) and water (26%) under the name Aculyn 44 Polymer by the company The Dow Chemical Company.

In a third variant, use may be made of a polycondensate of polyethylene glycol containing 200 mol of ethylene oxide, ether of polyethylene glycol containing 10 mol of ethylene oxide and/or of methylglucose, ether of polyethylene glycol containing 6 mol of ethylene oxide and of tridecyl alcohol, hexamethylene diisocyanate, and containing C16-C20 alcohol end groups, such as the product sold under the name Avalure® Flex 6 Polymer by the company Lubrizol (INCI name: Polyurethane-62).

Use is preferably made of the polyurethane polyethers described previously as examples.

[0047] Surfactants

[0048] The surfactant can result from a combination of different surfactants, including anionic, nonionic, and amphoteric (zwitterionic) surfactants. Anionic surfactants carry a negative charge on the polar head group. These surfactants are typically used for their detergency properties. They are highly effective at removing dirt and oil from the hair and scalp. Nonionic surfactants are those that have no (or very little) residual electric charge. These surfactants can perform a variety of functions, such as emulsion stabilization, mild detergency and viscosity modification. Amphoteric (zwitterionic) surfactants are dual-charged (have both a positive and negative charge on the molecule). Many amphoteric surfactants display pH-dependent charge behavior, having one charge at a lower pH and the opposite charge at a higher pH. These types of surfactants tend to be mild both to skin and hair. They can also provide foam-boosting properties in combination with anionic surfactants, which enhances lather.

[0049] The surfactant of the instant disclosure includes: (i) one or anionic surfactants; and (ii) one or more amphoteric surfactants. The surfactant system may also optionally include: (iii) additional miscellaneous nonionic surfactants.

[0050] The total amount of surfactants in the instant disclosure may be present in the ranges from about 2 to about 25 wt.%, by weight percentages based on the total weight of the cleansing mask composition. On some embodiments, the total amounts of surfactants maybe from about 4 to about 12 wt.%, by weight percentages based on the total weight of the cleansing mask composition.

[0051] The total amount of surfactants in the instant disclosure may be present from about 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 , 12, 13, 14 to about 14, 15, 16, 17, 18, 19, 20, 21 , 22, 23, 24, or 25 wt.%. by weight percentages based on the total weight of the cleansing mask composition.

Examples

[00131] The following examples illustrate the present invention but are not intended to limit the scope of the invention.

Table 1 : Inventive Examples

[00132] The Inventive Examples in Table 1 were prepared according to the procedure as follows. The solvents/carriers were mixed with water, then the thickeners(s) were added until well-dispersed. The pH was adjusted to neutralize the thickener(s) (if necessary). Actives were then added and mixed into the batch Surfactant(s) were then added and batch was stirred until uniform. The rheology modifier(s) were then added and mixed until batch was uniform. Finally, any other preservatives, additives, and fragrance were added, if present. Once well-mixed and uniform, the batch was complete.

[00133] Evaluation of the rheology of the composition Table 2: Comparative Examples

[00134] Experiments

[00135] Rheological Measurement

[00136] The rheological measurements of the compositions were conducted with a TA Instruments Discovery HR-2 Hybrid Rheometer. Experiments were performed with a 40 mm diameter parallel plate geometry with 1 mm gap, and at a controlled temperature of 25°C throughout sample acquisition. After loading, sample was equilibrated for 1 min. Then, an amplitude sweep experiment was performed at a frequency of 1 Hz and a % oscillation strain ranging from 0.01 to 1000. Data was analyzed using TRIOS software. (See Fig. 1)

[00137] Interpretation

[00138] The loss modulus absolute value G” for Inventive Ex.1 (squares, dashed line) was less than 3 times the storage modulus absolute value G’ for the same formula (squares, solid line). See Fig.1. Inventive Ex.1 showed good spreading over the skin and a drip-free texture.

[00139] The loss modulus absolute value G” for Comparative Ex. 7 (triangles, dashed line) was significantly higher than the storage modulus absolute value G’ for the same formula (triangles, solid line) See Fig.1.

[00140] The Comparative Ex. 7 exhibited very poor spreading on skin and was not able to be uniformly applied. It is important to note that the absolute values of G’ and G” in Pa is not a key attribute for the instant disclosure; it is the ratio between them that is important. That is, the G” and G’ were greater for the Inventive Ex. 1 than the respective values of G” and G’ for the Comparative Ex. 7; however, the spreading was easy and drip-free for the Inventive Ex. 1 because G” was less than three times G’.

[00141] Note: The relevant % oscillation strain region correlating to skin care application (i.e., rubbing product on skin) for the measurements is represented in a box for clarification.

[00142] Evaluation on skin

[00143] A known amount of composition was picked up with finger and applied to the forearm while elevated and parallel to the ground. A thick layer was applied and rubbed onto skin surface and rubbed gently in a back and forth motion for 3 seconds. During application, records were collected if the formulation remained smooth or if any unacceptable ‘pilling’ or ‘balling up’ took place. Then, any dripping was assessed by observing over a time period of a few minutes any migration of the formula downward (away from the initial application site) due to gravity.

[00144] Interpretation

[00145] Comparative Ex. 7 contained the same amount of rheology modifier (i.e. Steareth-100/PEG-136/HDI Copolymer) as Inventive Ex. 1 , as well as the other ingredients, the only difference is the absence of a second thickener. When compared to Inventive Ex. 1 , it was observed that when the rheology modifier was present without any other thickener, the cleansing mask didn’t drip, but was too thick and couldn’t be spread easily onto the skin. [00146] Comparative Ex. 8 contained no rheology modifiers, but contained the same amount of thickener as Inventive Ex. 1 as well as the other ingredients.

When compared to Inventive Ex. 1 , it was observed that when the rheology modifier is not associated with the second thickener, the cleansing mask was too thin and was dripping once applied onto the skin.

[00147] According to the results described above, the association of a first thickener such as a non-acrylate based rheology modifier with a thickener such as an acrylic- or acrylate based thickener within a certain range exhibited an unexpected aesthetic appeal as well as advantageously remained in place on the skin, i.e. didn’t drip or run from the surface on which it was applied.

[00148] Evaluation of Deposition of Skin Care Active Ingredient

[00149] The Inventive Examples were evaluated to measure the deposition of the skin care active ingredients onto the skin after being applied and rinsed off and compared to several commercially available products (Benchmark Product 1 and Benchmark Product 2)

[00150] The measurements were done with an analytical team. The Inventive Examples were applied to a person’s forehead for 10 min, then rinsed off. Then, a few outer layers of skin were removed with tape stripping. The collected layers were analyzed with HPLC to quantify salicylic acid that was deposited on skin. The results are represented in Table 3 below.

Table 3

[00151] The deposition of salicylic acid observed for the Inventive Ex.1 containing 1.5% of Salicylic Acid was 47.71 ug. The deposition of salicylic acid observed for the commercially available products containing 2% of salicylic acid was between 35 ug and 37.21 ug. The formulas containing 1.5% surprisingly exhibited a higher salicylic deposition compared to the commercially available products containing 2% of salicylic acid. Therefore, it appeared that the deposition of salicylic acid increased with the inventive examples. The combinations of a thickener such as a non-acrylate based rheology modifier with an acrylic- or acrylate based thickeners presented in the present disclosure surprisingly improved the deposition of salicylic acid.
