The system can include: a conduit having a first dimension with an inlet and outlet; an extruder having an inlet and an outlet located within the conduit, an extruder orifice having a second dimension that is smaller than the first dimension; a carrier fluid reservoir coupled with the conduit inlet; an extruder reservoir coupled with the extruder inlet; and a particle collector fluidly coupled with the conduit outlet, wherein the particle collector has a collector inlet with a first temperature and a collector outlet with a second temperature. The method can include flowing carrier fluid through the extrudate conduit; extruding wax with the extruder into the carrier fluid that is flowing through the extrudate conduit such that the extrudate separates into extrudate segments separated from each other by carrier fluid segments; and flowing the extrudate into the particle collector so as to form wax particles.

The present invention relates to self-healing shells incorporating amphiphilic molecules having metal-coordinating group(s) reversibly cross-linked with metal cations.

Related treatments are also disclosed.

The present invention relates to a self-emulsifiable composition including a monoacyl phospholipid, a diacyl phospholipid, oils and fats, and a polyhydric alcohol, in which the content ratio between the monoacyl phospholipid and the diacyl phospholipid is in the range of monoacyl phospholipid:diacyl phospholipid=1:9 to 9:1 as a mass ratio.

Systems for preserving a cosmetic formulation and for preventing growth or survival of microorganisms on a cosmetic formulation include a cosmetic container and a cosmetic formulation disposed therein and having an argon gas reservoir which is formed within the cosmetic formulation such that rupturing the reservoir releases argon gas onto an adjacent cosmetic-air interface and displaces oxygenated air therefrom. Methods for manufacturing and preserving a cosmetic formulation include preparing a cosmetic formulation that is free of exogenous chemical preservatives but may contain natural preservatives, forming the argon gas reservoir, and sealing a container containing the cosmetic formulation in a nonvacuum, argon gas environment to form an argon gas blanket in the container headspace. The argon gas reservoir can be formed as microbubbles or a chimney of argon gas disposed vertically in the container or as other discrete pockets within the formulation and/or container.

A method for making highly soluble Stevia sweetener compositions is described. The resulting sweetener compositions readily provide high concentration solutions, and also possess superior taste qualities. The compositions can be used as sweeteners, sweetness enhancers, and flavor enhancers in foods, beverages, cosmetics and pharmaceuticals.
