Problems solved by technology

Previously, however, such water-soluble release polymers had a rapid release profile - releasing the desired component within days of first use, making these polymers unsuitable for lasting the entire life of the oral care implement
Alternatively, such water-soluble release polymers may require low processing temperatures (below 130°C), as such polymers would degrade severely at temperatures above 130°C, destroying the controlled release properties
Such low processing temperatures result in long manufacturing times

Embodiment

[0101] The following experiments were performed to measure the effect of the release additive on the release rate of the water soluble matrix. Experimentally tested formulations containing the following ingredients:

[0102] Water-soluble polymers ("WDPs") which are polyvinylcaprolactam-polyvinyl acetate-polyethylene glycol graft polymers having a processing temperature of at least 130°C

[0103] Cooling sensates ("sensates") - menthol derivatives of N-ethyl-5-methyl-2-(1-methylethyl)cyclohexanecarboxamide

[0104] L-arginine ("arginine")

[0105] Fatty component which is glycol monostearate ("GMS")

[0106] Table 1

[0107]

[0108] The formulation was then prepared by powdering all raw materials, mixing well and then heating at 140°C until the WDP melted and a solid "lump" was obtained. Study the dissolution of these "lumps" to understand the effects of additives, release slits, etc.

Abstract

Described herein is an oral care implement comprising: a handle; and a head coupled to the handle, the head comprising a main body and a release component coupled to the main body, the release component comprising: a water-dissolvable matrix comprising a first polymer having a processing temperature greater than or equal to 130 DEG C; and a release agent comprising a sensate; wherein the release agent is dispersed throughout the water-dissolvable matrix.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Provisional Patent Application Serial No. 62 / 771,639, filed November 27, 2018, which is incorporated herein by reference in its entirety. Background technique [0003] Toothbrushes comprising water soluble release polymers are known to provide release of desired components to the user. The function of such water-soluble release polymers is to provide a user-perceivable response - such as a color change - upon exposure of the water-soluble polymer to water during use. Previously, however, such water-soluble release polymers had a rapid release profile - releasing the desired components within days of first use, making these polymers unsuitable for lasting the entire life of the oral care implement. Alternatively, such water-soluble release polymers may require low processing temperatures (below 130°C), since such polymers would degrade severely at temperatures above 130°C, thereby des...
