Aqueous mixtures can include cellulose nanocrystals and sulfonated polyester, where a glass transition temperature (T.sub.g) of the sulfonated polyester is greater than 25° C. In some instances, exemplary aqueous mixtures also include one or more additives, such as pigment. Exemplary aqueous mixtures can be applied as a film that is typically hydrophobic and resilient against water at room temperature. Upon application of warm water, such as at temperatures of from about 30° C. to about 60° C., the film can be removed with no or limited abrasion and/or with no or little removal oils.

A cosmetic activator system for activating a cosmetic is provided including: an activator having an energy source configured to emit an energy pulse and a controller; and an imprinter having an imprint pattern and at least one activation element configured to be in communication with the energy source, wherein the imprinter is configured to create an imprint on the cosmetic.

The present invention generally relates to systems and methods for treating vitiligo. In one set of embodiments, the present invention comprises a composition comprising pyruvic acid and/or a pyruvate salt. The composition may be formulated for application to the skin of a subject, for instance, as a gel, lotion, cream, ointment, soap, or stick. In some cases, the composition may comprise a lecithin, such as phosphatidylcholine. In certain embodiments, the lecithin is present as a liquid crystal, and/or in liposomes, micelles, or other vesicles. Other aspects of the present invention are generally directed to methods of making or using such compositions, methods of promoting such compositions, kits including such compositions, or the like.

A method of producing cosmetic skin dye, including a) extracting the liquid contained in the pecan husks, b) separating the extracted liquid in oil and sediments by means of natural sedimentation, c) homogeneously mixing said sediments with oil of the pecan husks to produce said skin dye, and d) applying the cosmetic skin dye in the skin of a user. The pecan husks are obtained from an unripe pecan. A higher concentration of sediments in the homogenous mixture produces a darker shade of cosmetic dye.

Disclosed is a self-invertible inverse latex having an aqueous phase, including: a) a cross-linked anionic polyelectrolyte (P) including: —at least one first monomer unit derived from at least one monomer selected from the elements of the group consisting of acrylic acid, methacrylic acid, 2-carboxyethyl acrylic acid, itaconic acid, maleic acid, 3-methyl 3-[(1-oxo-2-propenyl)amino]butanoic acid, the carboxylic function of the monomers being in the free, partially salified or totally salified acid form; and —at least one monomer unit derived from a polyethylenic cross-linking monomer (AR); b) ethylenediamine disuccinic acid in the form of trisodium salt.
