A composition contains n-heptyl-glyceryl ether and at least one further carefully chosen and synergistically active preservative.

Single layer and multilayer vesicles with actives inside are delivered into living tissue. Then, the vesicles are disrupted using ultrasound. The vesicles are used to create an image in the tissue or for the delivery of certain actives to the skin.

The present invention provides nanoparticle compositions comprising AE nanoparticles. The present invention provides AE nanoparticles comprising one or more amphiphilic entities and pharmaceutical compositions comprising AE nanoparticles. The present invention provides methods of manufacturing AE nanoparticles. The present invention provides methods of delivering a biologically active agent to a subject by administering AE nanoparticles containing a biologically active agent to a subject.

The present invention relates to a film-forming composition for skin or hair coating. The film-forming composition for skin or hair coating according to the present invention exhibits a feeling of lightness when applied to skin or hair and has excellent durability to protect skin or hair itself, and also, can protect cosmetic applications to the skin, etc. Also, the present invention separates and prepares silane and water so that a film is formed at the time of application, thereby being convenient in use.

Methods for screening skin cleansers for mildness can include utilization of a volume ratio of vesicles to micelles.

A sunscreen composition includes a sunscreen active, a carrier, and a film former polymer. The sunscreen active may be selected from organic sunscreen actives. The carrier may include an amphiphile monolayer to encapsulate a least a portion of the total amount of the sunscreen active. The film former polymer may include an acrylic film former polymer selected from C.sub.1-C.sub.30 alkyl (meth)acrylates copolymer. Notably, the sunscreen active may provide enhanced photoprotection at relatively low concentration levels when present with the carrier, including the amphiphile monolayer, and the acrylic film former polymer.

The present invention relates to potassium hydrogen alkylhydroxamate compounds and compositions and formulations comprising same, processes for preparing the inventive potassium hydrogen alkylhydroxamate compounds, as well as applications thereof including the use of the inventive compounds and compositions in formulations of products or components of products.

A makeup removal composition includes a blend of oils comprising one or more branched or linear liquid alkanes with carbon chain length of C11 to C20, including isohexadecane and isododecane, and one or more emollient esters, at least one polymeric thickener for a water-based system, at least one polyglyceryl nonionic surfactant and water in a bi-phase micellar system having oily and water phases, the water phase including water present from about 30% to about 70% by weight of the makeup removal composition wherein water and oil are present in a ratio of water to oil from about 1.5:1 to about 1:1.5. The product removed by wiping without rinsing with water.
