Provided are a cleaner base containing a solid composition including a solid surfactant and a water-soluble polymer, a gel cleaning composition having a viscosity of greater than or equal to about 50 cPs including the cleaner base containing a solid composition and water, and a method for preparing the gel cleaning composition.

A frozen serum and applicator thereof is disclosed, including a mold having a first half releasably engaged with a second half. When engaged, the first half and the second half form a reservoir therebetween to accept a volume of a serum. The serum is frozen within the mold to produce a frozen serum having at least one receiver molded thereon to releasable engage with an applicator configured to permit the frozen serum to be rolled. An opening is provided on the mold to permit the serum to be disposed within the reservoir.

A composition is disclosed that includes pure silk fibroin-based protein fragments that are substantially devoid of sericin, wherein the composition has an average weight average molecular weight ranging from about 17 kDa to about 38 kDa, wherein the composition has a polydispersity of between about 1.5 and about 3.0, wherein the composition is substantially homogeneous, wherein the composition between 0 ppm to about 500 ppm of inorganic residuals, and wherein the composition includes between 0 ppm to about 500 ppm of organic residuals.

A kit includes a multi-phase oral composition for whitening teeth and an electromagnetic radiation source. The multi-phase oral composition for whitening teeth includes from about 0.002% to about 30%, by weight of the multi-phase oral composition, of a discontinuous aqueous phase having a bleaching agent, where a concentration of the bleaching agent is up to 10%, by weight of the multi-phase oral composition, and at least about 50%, by weight of the multi-phase oral composition, of a continuous hydrophobic phase of petrolatum. The electromagnetic radiation source is capable of directing electromagnetic radiation with one or more wavelength in the range from about 200 nm to about 1700 nm toward at least one tooth. The electromagnetic radiation source emits electromagnetic radiation in a range from about 100 mW/cm.sup.2 to about 250 mW/cm.sup.2.

The invention described herein includes a self-neutralizing amino acid-based cationic composition that contains an amino acid-based cationic ester, a nonionic amphiphile, and an anhydrous buffering agent. In an embodiment, the composition, when dispersed or dissolved in an aqueous solvent, provides a resultant solution/dispersion having a pH of greater than about 4. The amino acid-based cationic ester may be a reaction product of (i) an amino acid having a non-polar side chain, and an amine group that has been neutralized with an acid; with (ii) a long chain fatty alcohol. Also included within the scope of the invention are methods of preparing a self-neutralizing amino acid-based cationic composition, such method including combining an amino acid-based cationic ester, a nonionic amphiphile and an anhydrous buffering agent. The resulting composition is in an anhydrous solid form. Formulations containing the amino acid-based cationic ester and/or a composition that includes it, are also disclosed.

A device to deliver an oral care substance to a tooth surface or a gingival tissue surface includes a body and an oral care substance. The body is orally acceptable and malleable, including beeswax and having a first surface configured to be applied to the tooth surface and/or the adjoining gingival tissue surface. The first surface is configured to adhere to the tooth surface and/or the adjoining gingival tissue surface. The oral care substance is deposited on the first surface and/or impregnated into the body, the substance being configured to contact the tooth surface and/or the adjoining gingival tissue surface.

This invention relates to solid oral care compositions, for example a tablet, comprising a comprising a sugar alcohol and a lubricant. In certain aspects the invention is directed to solid oral care compositions that are tablets that comprise a lubricant, wherein the lubricant comprises a poloxamer, as well as methods of use and related kits.

A depilatory wax additive and process. The depilatory wax additive may modify a depilatory hard wax composition to include visual, olfactory, or skin treatment components. A depilatory wax additive may include molded hard wax component and glitter, a color modifier, a scent modifier, or a skin treatment. A preexisting hard wax composition of solid particles may be heated to a liquid. The depilatory wax additive may be added to the liquefied preexisting hard wax composition, mixed, and heated to disperse the glitter, a color modifier, a scent modifier, or a skin treatment in the wax mixture.

The present invention relates to a solid phase cosmetic composition comprising a freeze-dried component of a composition comprising a functional component and a basic amino acid. A solid phase component according to the present invention has excellent re-dissolvability, and exhibits insignificant changes in the hardness and pH of the composition for dissolving the solid component even after re-dissolution, and thus a cosmetic having excellent stability can be provided.
