Problems solved by technology

While previously known methods for conditioning the hair and skin by means of a skin-care or hair-care device successfully impart some benefits to the skin and hair, there are drawbacks.
As such, it is difficult for the conditioning agent to separate from the mixture to provide maximum conditioning properties to the contact surface.
As such, repeated use of these compositions can lead to a build-up of undesirable effects, including, for example, a heavy, oily feel to the contact surface.
Additionally, it is often difficult to transfer a significant amount of the agent from the device or product to the skin or hair surface over an extended period of time.
This is because, once the conditioning agent on or near the surface of the device or product has been removed or transferred to the skin or hair, little of any additional benefit is obtained from using the product or device.
The product or device therefore needs to be replaced in its entirety, adding to consumer costs and waste.

Conditioning Release of PDMS onto Hair

[0082]The following example illustrates the release of a conditioning agent (e.g., PDMS) from an immiscible composition contained on a personal care device into a contact surface (hair).

[0083]The immiscible composition discussed above comprising a hydrophobic conditioning agent and a hydrophilic polymeric material was extruded into three personal care devices. More particularly, the devices were hair styling devices, and, specifically, the hair styling devices were brushes.

[0084]The three brushes contained PDMS as the conditioning agent in the immiscible composition. One brush, which was new, was life-tested for 10,000 strokes using means generally available in the art, a second brush, which was also new, was life-tested for 30 strokes using means generally available in the art, and a third brush was environmentally conditioned without stroking a reference hair sample. As used herein, the term “stroke” requires the device to travel a minimum of ...

Conditioning Release of PDMS onto Hair from Device Plate

[0095]The following example illustrates the analysis of a panel of a personal care device coated with the immiscible composition discussed herein.

[0096]The immiscible composition discussed above comprising a hydrophobic conditioning agent and a hydrophilic polymeric material was coated onto a panel of a personal care device. More particularly, the personal care device was a hair straightener.

[0097]The coated panel was placed into a laboratory oven set at 200° C. and allowed to acclimatize for several minutes. A reference hair sample was then utilized to directly wipe the surface of the coated panel of the device. FTIR analysis of the hair following the wipe resulted in the FTIR spectra shown in FIGS. 6A-6C.

[0098]Specifically, FIG. 6A provides the spectrum results for the surface of the coated panel. FIG. 6B provides the spectrum results for the reference hair sample that was wiped across the surface of the coated panel. FIG. 6C...

Abstract

The present disclosure generally relates to a personal care device comprising an immiscible conditioning composition formed by combining a hydrophilic matrix, such as a polymeric material, and a hydrophobic conditioning agent. More particularly, the present disclosure relates to a personal care device comprising a hydrophilic matrix, such as a polymeric material, and a hydrophobic conditioning agent dispersed therein, such as a silicone or a siloxane-based agent suitable for transferring from the device surface, and more particularly the matrix surface, to hair or skin surfaces in contact therewith.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority from U.S. Provisional Patent Application Ser. No. 61 / 141,939, filed Dec. 31, 2008, the entire contents of which is incorporated herein by reference.FIELD OF THE DISCLOSURE[0002]The present disclosure generally relates to a personal care device comprising an immiscible conditioning composition formed by combining a hydrophilic matrix, such as a polymeric material, and a hydrophobic conditioning agent. More particularly, the present disclosure relates to a personal care device comprising a hydrophilic matrix, such as a polymeric material, and a hydrophobic conditioning agent dispersed therein, such as a silicone or a siloxane-based agent suitable for transferring from the device surface, and more particularly the matrix surface, to hair or skin surfaces in contact therewith.BACKGROUND OF THE DISCLOSURE[0003]Conditioning agents are commonly employed to enhance the manageability, health and / or appearance of the...
