Methods of making personal care compositions, such as dentifrices, involving the addition of rheology modifiers at a later stage in the personal care composition formation process.

Late stage addition of rheology modifier

The present invention generally relates to microparticles and, in particular, to systems and methods for encapsulation within microparticles. In one aspect, the present invention is generally directed to microparticles containing entities therein, where the entities contain an agent that can be released from the microparticles, e.g., via diffusion. In some cases, the agent may be released from the microparticles without disruption of the microparticles. The entities may be, for instance, polymeric particles, hydrogel particles, droplets of fluid, etc. The entities may be contained within a fluid that is, in turn, encapsulated within the microparticle. The agent may be released from the entity into the fluid, and then from the fluid through the microparticle. In such fashion, the release of agent from the microparticle may be controlled, e.g., over relatively long time scales. Other embodiments of the present invention are generally directed to methods of making such microparticles, methods of using such microparticles, microfluidic devices for making such microparticles, and the like.

Methods for encapsulation of actives within droplets and other compartments

A rinsable personal care composition includes (a) 0 to 75 weight percent of a composition surfactant; (b) 0.01 to 99 weight percent of a skin benefit agent or emollient; (c) 0.01 to 20 weight percent of a hydrophobically modified non-platelet particle; and (d) 0 to 99% water.

Personal care compositions containing hydrophobically modified non-platelet particles

Disclosed are personal cleansing compositions, and corresponding methods of application, wherein the compositions comprise (A) a cleansing phase containing a cleansing surfactant and water; and (B) an active phase containing lipophilic carrier and preferably a skin active agent; wherein the cleansing and active phases are physically separated from one another by one or more packaging barriers, located in the same or separate packages. Preferred embodiments are further defined by selected lipophilic carrier rheologies, defined active phase particulates for improved skin feel, and selected chronic skin active agents for use in the active phase. These compositions and corresponding methods provide improved cosmetics, skin feel, and/or skin active efficacy.
