Description

Self-effervescent peel-off cleansing mask

FIELD OF DISCLOSURE

The present invention relates to a self-effervescent peelable cleansing mask composition.

CONTEXT

A goal of the cosmetics industry is to deliver highly effective products to consumers that provide benefits to the skin, such as moisturizing, hydrating, whitening, cleansing, and so on.

Among all the compositions for caring for keratinous materials, in particular the skin, masks are known for their high penetration efficiency on keratinous materials. But they use a certain amount of water in order to eliminate them.

Therefore, the object of this disclosure is to create a cleansing mask product that not only provides deep cleansing properties, but also helps to limit water consumption.

In view of the above remarks, it would be beneficial to provide a skin cleansing mask composition that uses less water than a traditional cleansing mask. Here we present such a composition which forms a film on the skin which can be peeled off from the surface of the skin in one piece without the use of water and which also has a unique sensory aspect of self-effervescence. Furthermore, the auto-effervescent action is accomplished without the use of perfluorinated compounds, which are known to cause several environmental and health issues. It will also be unique in its ability to have a good deposit of active ingredients for the skin.

Without being tied to any theory or mechanism, it is suggested that the self-effervescence that begins upon contact with the skin is due to the rapid evaporation of the volatile silicone oil when the raw formula is spread thinly.

It should be understood that the foregoing general description and the following detailed description are both exemplary and explanatory, and are not restrictive of the invention.

DETAILED DESCRIPTION OF THE DISCLOSURE

This disclosure relates to compositions for cleansing the skin.

The cleansing mask compositions of the present disclosure, in their broadest sense, typically include the following:

1. from about 8 to about 20% by weight of a polyvinyl alcohol;
2. from about 0.2 to about 10% by weight of at least one sugar alcohol;
3. from about 0.1 to about 50% by weight of at least one surfactant;
4. from about 0.2 to about 2% by weight of at least one or more hydrophobically modified polymers;
5. at least one silicone oil; And

in which the composition ensures the action of auto-effervescence

wherein the weight percentages are based on the total weight of the cleaning composition.

The cleansing composition disclosed herein begins to be self-effervescent immediately after applying the composition to the skin. In some embodiments, the self-effervescent composition is self-effervescent within 10 seconds of applying the cleansing composition to the skin. Auto-effervescence then lasts at least about 3 minutes, at least about 3.5 minutes or more. After the composition dries to a film in less than about 10 minutes, the cleansing mask can be peeled off the skin in one piece.

As used herein, the term "peelable" means that the product peels off the skin. The combination of ingredients creates a peel-off film or peel-off mask.

As used herein, the terms "peelable mask" and "peelable" are used interchangeably throughout this disclosure.

As used herein, the term "self-effervescence" means that it is a composition which bubbles only when applied in a thin layer to the skin without the addition of any other stimuli. outside.

As used herein, the term "critical micellar concentration" refers to the chemical concentration at which aggregates begin to self-assemble.

polyvinyl alcohol

As used herein, the term "polyvinyl alcohol" means, within the scope of the present disclosure, a polymer comprising -CH2CH(OH)- groups with 1,3-diol linkages and/or 1,2- diol.

The polymer that provides the action of forming the peelable film must have a high elongation at break, so that the film formed is flexible and not brittle. It should also have medium adhesion, so that it binds the gel into a film but can still be easily lifted from the skin.

Polyvinyl alcohols are typically produced by hydrolysis of polyvinyl acetate via transesterification. The degree of hydrolysis of commercial products is variable, often around 87%, but there are also products with a degree of hydrolysis of 100%. There are also copolymers with monomers other than vinyl acetate, such as ethylene/vinyl alcohol copolymers.

The polyvinyl alcohol polymers as thickening polymers are preferably chosen from homopolymers or copolymers with vinyl acetate, the latter corresponding in particular to a partial hydrolysis of the polyvinyl acetate.

One can for example use the products of the Selvol range sold by SEKISUI SPECIALTY CHEMICALS under the names SELVOL™ ULTRALUX FF, Selvol™125, Selvol™ 103, Selvol™ 325, Selvol™ 523, Selvol™ 540, Selvol™ 205, Selvol™ 203, Selvol™ Polyvinyl Alcohols 805, Selvol™ Polyvinyl Alcohols 823, Selvol™ Polyvinyl Alcohols 840, Selvol™ Polyvinyl Alcohols 203S, 205S, 523S and 540S.

The following procedure was used for the formulation of the table above.

Solvents and preservatives were mixed at 20-25 C. Polyvinyl alcohol was added to the tank with maximum agitation. 20 grams of cold water were added per 100 grams of formula. The solution was heated to 80 C, maintaining maximum possible agitation without foaming, and allowed to mix until the gel pieces were no longer visible. The cetyl hydroxyethyl cellulose was dispersed in glycerin and then added to the tank. The solution was cooled to 25-30 C with stirring. The surfactants were mixed in 10 grams of water per 100 grams of formula and then added to the tank. The disiloxane was added to the tank and homogenized for 15 minutes.

Example 2

(Inventive and Comparative Examples)

The following examples are provided for illustration only and are not intended to be limiting.

The inventive and comparative examples have been studied. Bubble formation, film integrity, film peelability, and silicone suspension were visually assessed. The drying time of the formulas was also measured. The objectives were to invent a product that could:

1) be self-effervescent

2) dry to a film in less than 10 minutes, and

3) Form a film that can be peeled off the skin in one piece with little or no residual product left on the skin.

The peel-off mask is applied in the form of a film that is spread in a thin layer with the fingers on the face. Let it dry for several minutes, then peel it from the face with your fingers. It peels off in one piece as a film. It is typically preferred that this type of mask requires a relatively short drying time to peel off. These peel off masks usually offer deep pore cleansing and skin debris removal functions.

Comp. 3 ) , but with added cleansing function Without PVA, the formula becomes an unstable cleanser with no peeling function and no effervescent action Starch reinforces the formation of the film and the peelability of the formula Without the surfactants, there is no cleaning and no self-effervescent action, indicating that the surfactant micelles help stabilize the silicone

Ex. Comp. 1

Ex. Comp. 1 was a cleansing formula known for its self-effervescent properties, but lacked the ability to peel off. It did not contain polyvinyl alcohol.

Ex. Comp. 2

Ex. Comp. 2 contained polyvinyl alcohol. Adding this ingredient to self-effervescent cleaner (i.e. Ex. Comp. 1) has been observed to extend bubble life, but does not lead to a product that dries to a film peelable.

Ex. Comp. 3

Ex. Comp. 3 was a formula that dried to a peelable film but did not clean up or form any bubbles. The material which provided the self-effervescent action to Ex. Comp. 1, disiloxane, has been added to the formula (i.e. Ex. Comp. 4). It was then observed that even if the material which ensured the action of auto-effervescence in Ex. Comp. 1 was added to the formula, it did not form any bubbles. Therefore, the addition of the material which ensured the action of auto-effervescence to Ex. Comp. 1 to a peel off mask formula was not enough to create a formula that both peels off the skin and is self-effervescent.

Ex. Comp. 5

Ex. Comp. 5 included relevant key elements of the self-effervescent formula (i.e. Ex. Comp. 1) and the peel-off mask (i.e. Ex. Comp. 3). It has been prepared with solvents, preservatives, polyvinyl alcohol, the agent used to induce disiloxane auto-effervescence, and surfactants which ensure the cleaning action. A secondary film former, Hydrogenated Starch Hydrolyzate, has also been added to enhance film formation and peelability. The result is a gel that meets the three objectives of the invention; however, the gel phase separated within 24 hours.

Ex. Comp. 6

Ex. Comp. 6 was comparable to Ex. Comp. 5, but glycerin and a polymeric thickener, xanthan gum, were added to the mix. The result is a thickened gel that also met all three objectives of the invention and experienced phase separation within 24 hours. An alternative polymeric thickener, cetyl hydroxyethyl cellulose (CHEC), was substituted for xanthan gum and the result was a stabilized formula that met all three objectives of the invention, i.e. Ex. invention1. Thus, the choice of the polymeric thickener had an impact on the stability of the invention. Specifically, a hydrophobically modified polymer was needed to stabilize the silicone in the aqueous formula.

Ex. Comp. 7

Ex. Comp. 7 was comparable to Ex. Comp. 6, but there was no cetyl hydroxyethyl cellulose (CHEC). It was observed that without the thickener, the invention phase separated and lost its peelability.

Ex. Comp. 8

When the filmogendisiloxane was removed from Ex. Inv.1, the formula was comparable to a peel off mask (ie Ex. Comp. 3) with added cleansing power. It was not self-effervescent. Thus, a pseudo-stable silicone in the formula but which evaporated quickly when the formula was spread was necessary for the auto-effervescence action.

Ex. Comp. 9

When polyvinyl alcohol was removed from Ex. Inv.1, the formula became an unstable cleanser with no peeling action or self-effervescence. With only polyvinyl alcohol or hydrogenated starch hydrolyzate in Ex. Inv.1, the formula was self-effervescent and dried to a film, but the film did not peel easily from the skin and left residue. Thus, both film formers were needed to obtain a substantial film that could be peeled from the skin.

Ex. Comp. 10

When the film former was removed from Ex. Inv.1, the formula was not self-effervescent or did not clean up well. It would dry into a film that could be peeled off the skin, but was not easily removed and left a residual product. Surfactants were therefore necessary for the cleansing and effervescent action. Additionally, the surfactant concentration must be above the critical micellar concentration of the surfactant mixture to accomplish these actions. The starch enhanced the film formation and the peelability of the formula.

Ex. Comp. 11

Ex. Comp. 11 did not contain any of the surfactants present in Ex.Inventif. 1. Without the surfactants, there was no cleaning action and no effervescence, indicating that the surfactant micelles helped stabilize the silicone.

Further, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Accordingly, it is intended that the invention not be limited to the particular embodiment disclosed as being the best mode contemplated for carrying out the present invention, but that the invention shall include all embodiments falling within the scope of the appended claims. .
