A changing color composition in the form of a gel for caring for and/or making up keratin materials is disclosed. The composition comprises in a physiologically acceptable medium, a) from 0.1 to 10% by weight preferably from 0.5 to 10% more preferably from 1 to 5% by weight relative to the weight of the composition of microcapsules containing releasable colorant(s), said microcapsules comprising: a core comprising one organic material, at least one layered coating surrounding said core, the layered coating comprising at least one polymer at least one colorant, and advantageously at least one lipid-based material, b) at least 3% by weight, preferably at least 5% by weight, more preferably at least 8% by weight and advantageously at least 10% by weight relative to the weight of the composition of an aqueous phase comprising water and at least one compound chosen from polyols, glycols and C2-C8 monoalcohols, and mixtures thereof, and c) at least one hydrophilic gelifying agent.

The invention relates to new anti-wrinkle and anti-aging nanoformulations, composed of non-toxic mesoporous silica nanoparticles, natural plant extracts (as the case may be: pomegranate oil, fennel oil, rosemary oil, chamomile oil, jojoba oil, rosehip oil), biological active agents (acetyl hexapeptide-8, aspartic acid), vitamins and others. Additionally, the present invention relates a new method for preparing the nanoformulations by co-encapsulating its active agents within a multilayer nanocarrier, thereby, enhancing their delivery through the skin barrier and their controlled accumulation at the desired site.

In certain embodiments, the active molecules are co-incorporated into an inner polymeric shell (silica derivatives) and onto its surface, followed by, the protection of an outer layer of chitosan-TAT (GRKKRRQRRRPQ). The active ingredients are crossed through the skin barrier using the disclosed delivery system to promote cell growth, skin rejuvenation and wrinkle removal.

An oil-enclosed powdery composition includes an oil-enclosable powder; further comprising; a platy powder, aluminum hydroxide coating the platy powder, having a surface of a specific surface area of at least 10 m.sup.2/g, and a fluorine compound coating the aluminum hydroxide; and an oil droplet having at least 50% by mass of hydrocarbon oil based on a total oil component and at least 2.010.sup.2 N/m of a surface tension value as a total oil component; wherein the oil-enclosable powder encompassing the oil droplet is like powder having an average particle size of 10 to 150 m and the oil-enclosed powdery composition is liquefiable by inunction.

An aqueous liquid cosmetic containing 1 to 20% by mass of (A) a flake aluminum powder coated with a layer containing a silicon compound; 0.5 to 10% by mass of (B) a polycarboxylic acid-based dispersant having a mass-average molecular weight of 10,000 or less; and 1 to 40% by mass of (C) a film-forming polymer emulsion in terms of a solid content is provide. Normally, the aqueous liquid cosmetic contains at least 40% by mass of water, and further may optionally contain (D) a color pigment as another ingredient. This aqueous liquid cosmetic is suitable for eye makeup applications such as eyeliners, eyebrows, eye colors, and the like.

Disclosed is a composition having a substrate comprising metal oxide particles. The substrate has a coating thereon that includes an organic dispersant present in a amount that renders the substrate self-dispersible. Also disclosed is a composition, such as a cosmetic composition, that includes that self-dispersible coated substrate, and a process that includes coating a particulate metal oxide with an organic dispersant to render the metal oxide self dispersible.

The instant invention relates to a composition for cosmetic raw material containing microcapsule containing at least one encapsulated material comprising at least one core and at least one layered coating surrounding the core, and the encapsulated material being at least one particle having a high wet point and being optionally porous, and being only released from the microcapsule when the composition is applied onto a keratin material, such as keratin fibers or skin. The invention further relates to a method for preparing the composition for cosmetic raw material containing microcapsule containing at least one encapsulated material comprising at least one core and at least one layered coating surrounding the core, and the encapsulated material being at least one particle having a high wet point and being optionally porous, and being only released from the microcapsule when the composition is applied onto a keratin material, such as keratin fibers or skin.
