Description

PERSONAL CARE DISSOLVABLE FILMS

Field

The present invention relates to personal care products and methods of making and using the same.

Background

Personal care films offer a convenient platform for delivering compositions, such as for skin care, hair care, or cosmetics applications. Such films are designed to quickly dissolve upon contact with water or aqueous compositions provided by the end user. An important goal in the industry is that the performance of these films will rival that of their conventional wet counterparts, while providing the greater portability and convenience of a film.

The success of a cosmetic, including personal care films, depends in great measure on the way it feels to a user. Thus, speed of dissolution and sensory attributes, such as ease of spreading, speed of absorption, texture, skin moistness, heaviness, amount of grease, amount of tack, quickness of drying, overall skin feel, and overall appearance are critical factors. For example, if the product dissolves too slowly, it becomes gummy and lumpy and does not provide uniform film. In the past, personal care films have been developed that dissolve quickly, but have not attained tactile properties that would lead to a successful product.

Thus, what is needed are personal care films with even more desirable consumer properties. Summary

In one embodiment, the present invention provides personal care dissolvable films comprising water soluble film forming agent, cosmetically acceptable plasticizer, and detackifying agent. In another embodiment, the present invention provides an eye care composition dissolvable film, comprising a water soluble film forming agent, a cosmetically acceptable plasticizer, and a detackifying agent.

Detailed Description In one embodiment, the present invention provides a personal care dissolvable film, comprising a water soluble film forming agent, a cosmetically acceptable plasticizer, and a detackifying agent.

"Personal care" refers to compositions that are to be topically applied to a person. Examples of personal care compositions include skin care and cosmetic products (e.g., facial cream, moisturizers, lotions, sunscreens, foundation, mascara, eye-liner, lipstick, and the like), nail care products (such as polish and conditioners), and hair care products (including styling gels and hairsprays). A "personal care dissolvable film" is a readily dissolvable film containing a personal care composition. In one embodiment, such a film dissolves in less than a minute when wet with water or aqueous compositions and rubbed between fingers for example.

"Cosmetically acceptable" refers to ingredients typically used in personal care compositions, and is intended to underscore that materials that are toxic, irritating, or unpleasant smelling when present in the amounts typically found in personal care compositions are not contemplated as part of the present invention. The term "water-soluble film forming agent" includes polymers with a solubility in water, measured at 25°C, of at least 0.1 gram/liter (g/L). This solubility is preferably at least 1 g/L.

Examples

The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention. All percentages are by weight unless otherwise specified.

Example 1

Exemplary personal care dissolvable films contain the components recited in TABLE 1. "%" indicates percent by weight of film-forming composition.

TABLE 1

Part A ingredients are combined and mixed at a temperature of about 90⁰C until the polymer completely hydrates and dissolves. Then the Part A is cooled to room temperature. Part B ingredients are added to Part A one by one and mixed until the dispersion is uniform. The rest of ingredients are added to the batch in order and mixed until uniform.

The resulting composition is cast via conventional methods.

Example 2

Exemplary personal care dissolvable films contain the components recited in TABLE 2. Values are in percent by weight of film-forming composition.

TABLE 2

Part A ingredients are combined and mixed at a temperature of about 90⁰C until the polymer completely hydrates and dissolves. Then the Part A is cooled to room temperature. Part B and Part C ingredients are added to Part A one by one and mixed until the dispersion is uniform. Part E is premixed until it is uniform then is added to the batch and mixed until uniform.

The resulting composition is cast via conventional methods.

Example 3

A film-forming composition was made substantially according to the protocol described in Example 1, Batch 2. The "wet" film-forming composition was then diluted to a 35% solution (3.5 g of formula and 6.5 g deionized water) to obtain the same viscosity as the benchmark conventional liquid formula, SUDDEN CHANGE Under Eye Serum, as the wet film-forming formula contains higher solids content. A liquid to liquid comparison for sensory properties was deemed convenient, as no known commercial dissolvable film used as anti-aging eye gel / serum or anti-aging facial lotion exists.

Ten panelists applied 0.05 g of each sample to a marked area on their right or left forearms. Upon initial application, each sample was evaluated for ease of spread, speed of adsorbtion, slip, tackiness, firming property, smoothing of fine line wrinkles (once dry), and overall appearance. The evaluation scale was 0-10, with 10 being outstanding. The diluted Batch 2 outperformed SUDDEN CHANGE Under Eye Serum for all attributes recorded (spread, adsorption, slip, tackiness, smoothing, and overall) except firming, for which it was a point less.

The exceptional performance of the diluted Batch 2 is surprising. Generally, such a product would be expected to have unpleasant tactile properties due to the high quantity of film forming polymer. One of the major drawbacks of previously known film products was the poor sensory properties. Additionally, it is difficult to achieve quick dissolving films for leave-on products because of the low concentration of surfactant in the formula. However, the presently claimed film compositions overcome these problems. Without intending to be bound by theory, the detackifier component appears to reduce the tackiness of the film, increase the dissolution rate of the film (through action as a filler to break down the continuous film), provide a soft focus effect to mask skin wrinkles, and thicken the oil phase to improve the texture of the formula.

Example 4

Exemplary personal care dissolvable films contain the components recited in TABLE 3. "%" indicates percent by weight of film-forming composition.

TABLE 3

Part A ingredients are combined and mixed at a temperature of about 90⁰C until the polymer completely hydrates and dissolves. Then the Part A is cooled to room temperature. Part B ingredients are added to Part A one by one and mixed until the dispersion is uniform. Six panelists evaluated samples of the film-forming formulas according to the protocol described above in Example 3, applying 0.05 g of each sample to a designated area on their right or left arms and evaluating the formulations for tackiness. Batches 5-7 were preferred to the comparative batch ("Compar."), especially when the formulas closed to dry, where Batches 5-7 were noted to have a silkier feel and more natural look as compared to the comparative formula.

It is understood that the present invention is not limited to the embodiments specifically disclosed and exemplified herein. Various modifications of the invention will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the scope of the appended claims. Moreover, each recited range includes all combinations and subcombinations of ranges, as well as specific numerals contained therein. Additionally, the disclosures of each patent, patent application, and publication cited or described in this document are hereby incorporated herein by reference, in their entireties.
