The present invention provides nanoparticle compositions including one or more peptides. The present invention achieves transdermal delivery of such peptides without the need for peptide modification, or for use of chemical or mechanical abrasion or disruption of skin.

The present disclosure provides compositions comprising decontaminating compounds, and pharmaceutically acceptable salts thereof and methods of treating or preventing a contamination in a mammal, in particular, the composition can include a mixture of polyvinyl acetate and povidone, a coblock polymer of ethylene oxide and propylene oxide, a polyvinyl alcohol, or combinations thereof, and an aqueous suspending agent.

Provided are a pigment dispersion liquid for cosmetics having excellent dispersibility of carbon black and aging stability, and an aqueous liquid cosmetic using the same, which is suitable for hair dyes and the like. The pigment dispersion liquid for cosmetics contains, at least, water, a water-soluble organic solvent, carbon black, and a (methacryloyl ethylbetaine/acrylates) copolymer, and a ratio of the water to total solvents is 30 to 95% by mass.

This invention relates to stabilizer concentrates which improve the stability of mono- and/or diesters of mono- and/or diethylene glycol wax dispersions in personal care compositions, wherein the stabilizer concentrates comprising hydrogenated castor oil and betaines and are free of anionic surfactants.

It is an object of the present invention to provide a personal care composition having not only a low environmental impact and a good skin feel but also a high cleansing property. The object can be achieved by a personal care composition containing water and low substituted hydroxypropyl cellulose, wherein the low substituted hydroxypropyl cellulose has an average particle size (D.sub.50) on a volume basis by dry laser diffraction of 30 μm to 200 μm and an aspect ratio equal to or more than 1.0 and less than 5.0, and the like.

The present disclosure relates to the field of carrier and delivery systems for active molecular compounds. In particular, the present disclosure provides suspension formulations of aqueous dispersions for delivery to subjects (e.g., by injection).

One of the purposes of the present invention is to provide an aqueous dispersion comprising a cosmetic pigment, which aqueous dispersion is stable with time, capable of forming a film with sufficient water resistance (water repellency), and provides a stable cosmetic preparation which does not cause caking; and a method for preparing the aqueous dispersion. The present invention provides an aqueous dispersion of a cosmetic pigment, water and hydroxypropylmethyl cellulose phthalate, wherein the cosmetic pigment is surface-silylated with an alkyltrialkoxysilane. The present invention further provides a method for preparing an aqueous dispersion containing the cosmetic pigment having a surface-silylated with an alkyltrialkoxysilane.

Colloidal silver particles are incorporated into emulsions and other compositions that find use, for example, as pharmaceutical and dermatological serums, creams, lotions and ointments.

The present invention is directed to targeted delivery of a cold slurry underneath a patient's skin to improve the cosmetic appearance of the skin. The “target” tissue can be muscle tissue that when cooled cannot contract and cause wrinkles/lines in the skin to appear. The target tissue can also be adipose tissue that causes overlying tissue to sag and form wrinkles/lines. The cold slurry induces apoptosis, and reduces the size of the tissue, and causes the connective tissue supporting the skin to thicken and tighten, thereby reducing wrinkles/lines. Skin can also be tightened with cold slurry injected into the dermis layer of the skin or within the layers of the oral mucosa making a cold slurry treatment ideal for reducing the appearance of baggy skin after a patient loses weight and or for treating obstructive sleep apnea. Cold slurry can also be used to treat cellulite and acne.

The present disclosure relates to a topical skin care composition comprising colloidal oatmeal in combination with a Vincetoxicum officinale extract and/or a Populas alba extract. The present disclosure further relates to methods of treating symptoms of itch, redness, flaking, dryness, and/or roughness of the skin, scalp, and/or mucous membrane using such topical skin care compositions.
