Peptide-Based Systems for Delivery of Cosmetic Agents
US Patent Application 20100247590
Publication date: Sept. 30, 2010
Assignee: Johnson & Johnson (New Brunswick, NJ, US); E. I. Du Pont De Nemours and Company (Wilmington, DE, US)

This invention relates to compositions and systems comprising peptide-based reagents for delivery of cosmetic benefit agents to human hair, skin or nails. The invention is directed to cosmetic systems comprising a peptidic component comprising at least one binding domain that binds to human hair, skin or nails with a Kd or MB50 value of 10−5 molar or less, and which further comprises the first part of an affinity pair; and a stable dispersion of particulate benefit agent having average particle size of between about 0.01 micron and about 75 microns and the second part of the affinity pair. The at-least one binding domain has a greater binding affinity for the human hair, skin or nails than it has for the particles of the dispersion. Methods of using the cosmetic delivery systems of the invention are also described, including the application of a benefit agent and the removal of the benefit agent from human hair, skin or nails.

Pigmentation-Regulating Compounds
US Patent Application 20100247587
Publication date: Sept. 30, 2010
Assignee: Lipotec S.A. (Gavá-Barcelona, ES)

The applicant of the present invention has found that 6-substituted 7-methoxy-2,2-dimethylchromanes are capable of reducing the amount of melanin produced by the melanocytes by means of the inhibition of the enzyme tyrosinase and, in turn, to protect against damage caused by UV radiation. The invention provides a simple, effective and risk-free solution for treating, caring for and/or cleaning skin, hair and/or nails, comprising a mammal a 6-substituted 7-methoxy-2,2-dimethylchromane.

The cosmetic or pharmaceutical compositions containing the compounds of the present invention or their cosmetically or pharmaceutically acceptable salts can be used in different types of formulations for topical or transdermal application, and they can also be incorporated by means of techniques known by persons skilled in the art in different types of solid accessories such as, for example and in a non-limiting sense towelettes, hydrogels, adhesive (or non-adhesive) patches or face masks. They may also be incorporated in different makeup products such as, for example and in a non-limiting sense makeup bases, makeup removal lotions, makeup removal milks or under eye concealers, among others.
