Use of stinging cells/capsules for the delivery of active agents to keratinous substances
US Patent 7998509
Publication Date: Aug. 16, 2011
Assignee: NanoCyte Inc.

According to one aspect of the present invention there is provided a method of delivering an active agent into a keratinous substance, the method comprising applying a composition comprising the active agent disposed in or around at least one stinging capsule to an outer surface of a non-skin keratinous substance and triggering a discharge of the at least one stinging capsule to thereby deliver the active agent into the non-skin keratinous substance.

According to another aspect of the present invention there is provided a method of delivering an active agent into a keratinous substance, the method comprising applying a composition including, at least one active agent onto an outer surface of a non-skin keratinous substance, applying at least one stinging capsule to the outer surface of the non-skin keratinous substance and triggering a discharge of the at least one stinging capsule to thereby deliver the active agent into the keratinous substance.

According to yet another aspect of the present invention there is provided a method of delivering an active agent into a keratinous substance, the method comprising preconditioning a non-skin keratinous substance by administering into the non-skin keratinous substance at least one stinging capsule and triggering a discharge of the at least one stinging capsule to thereby deliver tubule of the at least one stinging capsule into the non-skin keratinous substance thus preconditioning the non-skin keratinous substance for subsequent delivery of the active agent and subsequently administering the active agent onto the non-skin keratinous substance, thereby effecting the delivery of the active agent into the keratinous substance.

Process for the photoprotective treatment of artificially dyed keratin fibers by application of a liquid water/steam mixture
US Patent 7998464
Publication Date: Aug. 16, 2011
Assignee: L'Oreal S.A.

The present disclosure relates to a process for treating keratin fibers artificially dyed by direct dyeing or by oxidation dyeing, such as human hair, which comprises the application to the keratin fibers of a composition not containing any oxidation dye or any oxidizing agent and comprising at least one protective agent with a log P of less than or equal to 6, and then the application to the fibers of a liquid water/steam mixture at a temperature of at least 35° C. The present disclosure also relates to the use of the process for protecting keratin fibers artificially dyed by direct dyeing or by oxidation dyeing, such as human hair, against the action of atmospheric agents, such as against the action of light.

Hair dye preparation composition
US Patent 7998223
Publication Date: Aug. 16, 2011
Assignee: Hoyu Co., Ltd.

A hair dye composition is provided that comprises a first agent containing an oxidation dye and an alkaline agent, and a second agent containing hydrogen peroxide, the hair dye composition being used after mixing the first agent and the second agent. The hair dye composition contains 1.0 to 5.0% w/w of an ascorbic acid compound and 0.3 to 1.6% hydrogen peroxide. The alkaline agent is contained in an amount of from 3.0 to 30 mmol per 100 g of the hair dye composition.

Cosmetic compositions comprising a polymer and a colorant
US Patent 7998222
Publication Date: Aug. 16, 2011
Assignee: The Proctor & Gamble Company

The disclosed cosmetic composition, suitable for use on mammalian skin, hair and nails, contain a polymer and a colorant. The polymer of the composition mitigates staining caused by the colorant, and the polymer and colorant are opposite in charge. The present invention is also directed to methods of mitigating skin staining through using the cosmetic compositions.

Hair follicle targeting compositions
WIPO Patent Application WO/2011/095970
Publication Date: Aug. 11, 2011
Assignee: J.P.M.E.D. Ltd. and D. Friedman

This invention provides topical pharmaceutical or cosmetic compositions, and uses thereof in treating a disease or condition of the hair follicle. The compositions of this invention are emulsions of an oil-in-polyol with a mean particle size of below one micron, and further comprising at least one oil, one polyol and one stabilizer.

Cosmetic or dermopharmaceutical composition containing Pseudoalteromonas ferment extract
US Patent Application 20110195103
Publication Date: Aug. 11, 2011
Assignee: Lipotec S.A.

Disclosed is cosmetic or dermopharmaceutical compositions containing Pseudoalteromonas ferment extract for the treatment and/or care of the skin, scalp and/or nails, preferably to improve the barrier function of the skin, scalp and/or nails, and specifically for the treatment and/or care of those conditions, disorders and/or pathologies of the skin, scalp and/or nails associated with an alteration in the keratinization process.

Peptides useful in the treatment and/or care of skin, mucous membranes, scalp and/or hair and their use in cosmetic or pharmaceutical compositions
US Patent Application 20110195102
Publication Date: Aug. 11, 2011
Assignee: Lipotec S.A.

This invention relates to peptides capable of inhibiting the activity of reactive carbonyl species (RCS) and to cosmetic and pharmaceutical compositions containing these peptides and their use in the treatment and/or care of skin, mucous membranes, scalp and/or hair, preferably for the treatment and/or care of said conditions, disorders and/or diseases of the skin, mucous membranes, scalp and/or hair which are the result of RCS generation.

Porous, dissolvable solid substrate and surface resident coating comprising water sensitive actives
US Patent Application 20110195098
Publication Date: Aug. 11, 2011
Assignee: RW Glenn Jr., KM Kaufman, JC Dunbar, JM Gardlik and BP Murphy

The present invention relates to personal care compositions, especially those personal care compositions in the form of a personal care article that is a porous dissolvable solid substrate. The porous dissolvable solid substrate has a surface resident coating comprising a water sensitive active that can deliver a consumer benefit.

Personal care compositions have traditionally been sold as liquid products. These liquid personal care products typically comprise a substantial amount of water in the formula. Traditionally it has been difficult to include water sensitive actives which are chemically incompatible or hydrolytically sensitive, due to the nature of the aqueous environment of the liquid product. By eliminating the aqueous environment (the solvent), the personal care products of the present invention have improved shelf stability of water sensitive chemically incompatible and hydrolytically sensitive actives.

During usage, the consumer adds water to the personal care product, which activates the water sensitive actives to deliver their consumer desirable benefit at the desired point of time of product application. Additionally, the personal care product of the present invention expands the number and type of cosmetic actives that can be employed by the formulator and enables the delivery of new consumer benefits which have previously been difficult to achieve without dual compartment packaging or by the consumer having to mix differing compositions in a multi-step process. Such consumer benefits are “water activated” and include, but are not limited to, self-lathering (effervescence), self-warming, gradual hair lightening/blonding, gradual hair coloring and visual color change of the product.

Hair building solid agent
US Patent Application 20110195039
Publication Date: Aug. 11, 2011
Assignee: Pangaea Laboratories Ltd.

Disclosed is a method of treating hair comprising applying a hair building solid agent for use on or with one or more of hair, skin and hair building solids for altering and/or maintaining the electrostatic charge of the hair and/or skin such that it has a substantially negative polarity. The method further comprises applying hair building solids to hair before and/or during and/or after applying the hair building solid agent. The hair building solid agent is applied as a spray on to the hair and/or skin and/or hair building solid.

Two-Phase Composition for Improving Curl Retention
