Oral care compositions containing a peroxide and a 2-acrylamido-2-methylpropane sulfonic acid polymers, copolymers, or cross polymers. The oral care compositions can also contain a fluoride ion source and a flavor.

An improved erasable tattoo ink and a method and apparatus for removing tattoos using an energy transfer photodisruptive mechanism whereby efficiency of the transfer of energy from a low energy light source to a higher energy donor and then to a tattoo pigment molecule for photodecomposition of the ink color pigmentation is optimized.

The present invention provides a foamable composition for administration to the skin, body surface, body cavity or mucosal surface, e.g., the mucosa of the nose, mouth, eye, ear, respiratory system, vagina or rectum, and methods of using such a composition to treat, alleviate, or prevent a disorder of the skin, body cavity, or mucosal surface. The foamable oil in water nano emulsion composition includes: (a) a nano oil globule system, comprising substantially of sub-micron oil globules; (b) about 0.1% to about 5% by weight of at least one stabilizing agent selected from (i) a non-ionic surfactant, (ii) an ionic surfactant, or (iii) a polymeric agent; and (c) a liquefied or compressed gas propellant at a concentration of about 3% to about 25% by weight of the total composition, water and optional ingredients. Upon release from an aerosol container, the foamable composition forms and expanded foam suitable for topical administration.

Compositions for delivering materials, such as a biological material, sand, soil, metal, water, sea water, holy water, synthetic or biological polymers, cremated ash, ceramics, animal or plant tissue, or another physiologically compatible component having personal significance to an individual are described herein. The material(s) are encapsulated in an inert, non-bioerodible, hydrophobic, polymeric material. Methods of making microparticles encapsulating the personalizing substance and methods of use are also provided. The personalizing substance may be encapsulated in a polymeric non-bioerodible microparticle. The encapsulated personalizing substance may be combined with a carrier for delivery to an individual's skin. In some embodiments, the personalizing substance is added to a tattoo ink and incorporated in a tattoo created on an individual's skin. Following injection in the skin, the encapsulated material remains in the microparticles, and is not released over time.

The invention described herein includes a self-neutralizing amino acid-based cationic composition that includes: from 10 wt % to 70 wt % of an amino acid-based cationic ester of formula (I):

##STR00001##

where R.sub.1 is a branched or linear alkyl group having 1 to 10 carbon atoms, R.sub.2 is a linear or branched carbon chain having 10 to 50 carbon atoms, where X.sup. represents a conjugate base; from 2 wt % to 25 wt % of an anhydrous buffering agent comprising a salt formed from a strong base and a weak organic acid; and a nonionic amphiphile having 10 to 35 carbon atoms in an amount sufficient to total 100 wt % of the composition. The composition may be in anhydrous solid form and may be a dispersion of particles of the anhydrous buffering agent in a mixture of the amino acid-based cationic ester and the nonionic amphiphile.

An oral care composition comprising zinc phosphate, stannous fluoride and an organic acid buffer system, as well as methods of using the same.

A multicomponent composition for coloration of materials such as keratin fibers, keratin material, keratin textiles including but not limited to hair, eyebrows, eyelashes, skin, nails and animal fiber textiles is disclosed. The multicomponent composition comprises a first component of a CDI link compound having inert or reactive termini and having at least two groups capable of in situ combination with carbodiimide which preferably are acid groups, a second component of a polycarbodiimide terminated by inert or reactive groups, a third component of a polyamine. Optional additional components are also disclosed.
