摘要:
An oil-in-water emulsion that is environmentally friendly and also exhibits antimicrobial activity is provided. More specifically, the oil phase of the emulsion includes a botanical oil derived from a plant (e.g., thymol, carvacrol, etc.). Because the botanical oil tends to leach out of the emulsion during storage and before it is used in the desired application, a water-dispersible polymer is also employed in the aqueous phase of the emulsion to enhance long term stability of the oil and, in turn, antimicrobial efficacy. Without intending to be limited by theory, it is believed that the water-dispersible polymer can effectively encapsulate the botanical oil within the emulsion and inhibit its premature release. Once the emulsion is formed, water can then be removed so that it becomes a substantially anhydrous concentrate. In this manner, the water-dispersible polymer will not generally disperse before use and prematurely release the botanical oil. When it is desired, moisture may simply be re-applied to the concentrate to disperse the polymer and activate the release of the botanical oil. Of course, to provide the optimum degree of biocompatibility, the water-dispersible polymer is also a “biopolymer” that is biodegradable and/or renewable.

A wipe that contains a fibrous web on which is coated an antimicrobial composition is provided. The composition includes a botanical oil derived from a plant (e.g., thymol, carvacrol, etc.). Because the botanical oil is volatile and tends to evaporate and lose efficacy during storage and prior to use, a protein is also employed in the composition to enhance long term stability of the oil and, in turn, its antimicrobial efficacy. The protein is “film-forming” in the sense that it tends to form a substantially continuous film when coated onto a surface of the fibrous web. Because such proteins are typically stiff and brittle in nature, a continuous film would restrict the ability of the fibers to move and bend, thereby reducing web flexibility and drape. Thus, it is typically desired that the antimicrobial composition form a discontinuous coating on the fibrous web. In this regard, the present inventors have surprisingly discovered that the addition of an organopolysiloxane can help achieve such a discontinuous coating without adversely impacting the ability of the protein to stabilize the botanical oil. The organopolysiloxane may also enhance the softness and overall handfeel of the wipe.

摘要:
The present invention relates to a wipe suitable for multiple re-use comprising a biopolymer matrix composition, said biopolymer matrix comprising from about 0.1% to about 40% of an essential oil, about 30% to about 95% of a biopolymer, and about 1% to about 50% of a carrier fluid wherein a limited amount of said essential oil can be released from said matrix composition when exposed to a liquid solution; and wherein an additional limited amount of said essential oil can be re-released repetitiously thereafter upon re-use with an additional exposure of a liquid solution to said wipe.
摘要:
The present invention relates to a personal care product comprising a protein matrix wherein said protein matrix comprises at least one protein, at least one probiotic and a carrier fluid.The present invention also relates to the personal care product being a feminine care product particularly aimed at female urogenital health to treat or prevent vaginal infections. Oral and sinus infections, however, may also be benefited by the composition.
摘要:
A cleaning medium or formulation that contains a sporicidal composition is described. The composition includes about 0.1-20% weight/weight of a germinant agent, about 0.01-75% w/w of an antimicrobial agent, in terms of dry or wet total weight, and which is admixed with water to generate a solution with a pH of 3.5-9.5. The composition can help trigger the germination of spores, in particular C. difficile, and subsequently deactivate or kill the spores. A means of applying the cleaning formulation in a medium and process for cleaning are also described.
摘要:
An article has a body facing engagement surface for contacting a wearer's tissue layer. The body facing engagement surface has a first state adapted to inhibit movement of the article with respect to the wearer's tissue layer, and a second state adapted to enhance movement of the article with respect to the tissue layer. The body facing engagement surface is adapted to transform from the first state to the second state upon application of a force greater than a threshold force. The body facing engagement surface has a gripping component that overlies a sliding component in the first state. The gripping component is disposed for engaging and gripping the tissue layer in the first state until a force greater than the threshold force is encountered which transforms the engagement surface to promote relative sliding motion between the engagement surface and the tissue layer.

A contact layer has an engagement surface adapted to contact a user's tissue layer. The contact layer is constructed so that the engagement surface has a first state adapted to inhibit movement of the contact layer with respect to the tissue layer of the user, and a second state adapted to enhance movement of the contact layer with respect to the tissue layer of the user. The engagement surface is adapted to transform from the first state to the second state upon application of a force greater than a threshold force.
摘要:
In a personal care article for contact with human skin, a non-woven substrate of the article has a longitudinal direction, a transverse direction and at least one skin-contact surface. A plurality of surface features is disposed on the at least one skin-contact surface in a sinusoidal wave-form along at least one of the longitudinal direction and the transverse direction of the substrate. The surface features have a height that generally defines an amplitude of the sinusoidal wave-form, and are spaced from each other a spatial distance. This spatial distance is at least in part a function of a movement speed at which the article is to be moved relative to the skin while in contact therewith. In one method of making such a substrate, the movement speed and a temporal frequency are selected and used to determine the spacing between surface features on the skin-contact surface of the substrate.
