Embodiment 1

[0076] Example 1: Hydrogel Compositions

[0077] An example of a hydrogel preparation according to the invention uses the ingredients shown in Table 1.

[0078] Table 1: Composition 1

[0079]

[0080] Composition 1 was prepared as follows.

[0081] Glycerin Premix

[0082] Step 1: Glycerin, carrageenan, and carob (carob) gum were placed in a beaker. Stir the composition with a spatula until a uniform consistency is reached.

[0083] water box

[0084] Step 1: In a second beaker, heat water to 85°C.

[0085] Step 2: Add Potassium Sorbate, Chlorphenesin, Phenoxyethanol, and Ethylhexylglycerin to the water in a second beaker and mix until all components are well dissolved / dispersed.

[0086] full mixture

[0087] Step 1: Add the aqueous mixture ("aqueous phase" above) to the glycerin premix while agitating the composition solution and maintaining it at 85°C for a minimum of 10 minutes to form a hydrogel of uniform consistency.

[0088] Step 2: The temperatur...

Embodiment 2 and 3

[0090] Examples 2 and 3: Reactively printable compositions

[0091] Application of the active benefit agent to the patch substrate can be accomplished by printing on one or more areas of the patch substrate. For water-soluble active benefit agents, the formulation can be printed onto areas of the mask where the formulation contains one or more benefit agents. An example of a printable formulation containing a water-soluble benefit agent is shown below:

[0092] The following compositions according to the present invention (ie, Compositions 2 and 3) were prepared using the ingredients shown in Table 2 and Table 3, respectively.

[0093] Table 2: Composition 2

[0094]

[0095]

[0096] Disperse the Niacinamide, Chlorphenesin, Phenoxyethanol, and Ethylhexylglycerin in the water and mix until all ingredients are completely dissolved (some slight heating helps to disperse).

[0097] Table 3: Composition 3

[0098]

[0099] To prepare the composition, add acetylg...

Abstract

A personalized topical application patch includes a patch substrate having a plurality of isolated regions; and one or more active benefit agents disposed at least one of the plurality of isolated regions.

Description

technical field [0001] The present invention relates to devices and methods for preparing and providing to a user a personalized topical application patch having spatially isolated regions for active benefit agents. Background technique [0002] Currently, many active substances are applied to substrates in batches, so that there is no site-specific application. This limits customization in and on the surface of the substrate. Accordingly, the specific treatment is applied over the entire body or surface of the article. Problems inherent in the foregoing include (1) overuse of actives (i.e., application to unnecessary areas); (2) potential adverse events from actives in unintended areas; (3) reduced (4) negative interactions between benefit agents or incompatible benefit agents and (5) limitations of product personalization. [0003] Therefore, there is a need to tailor the spatial arrangement of active substances on topically applied patches, especially in materials comm...
