Description

PERSONAL CARE COMPOSITIONS BACKGROUND Powdered soaps are typically produced by preparing an aqueous soap solution, drying the solution using a spray-drying or similar method, then adding a binder such as water and a non-ionic surfactant, and grinding it into a powder with a high-speed mixer. To increase solubility, the water content of powdered soaps prepared in this way is usually kept to approximately 7 to 15%. However, such powdered soaps have poor flowability and / or feel. Therefore, these powdered soaps are preferably used only as laundry detergents that require high solubility and can be scooped with a measuring cup. To improve flowability, the water content is between 1% and 3%.Therefore, there is a need for a powdered soap that can exhibit good flowability and a good feel and maintain solubility; in this way, a powdered soap suitable for personal care applications is manufactured.

The mixture can be gently stirred until the various components are uniformly distributed throughout. According to some embodiments, the mixture may further comprise one or more liquid carriers (e.g., water, non-aqueous solvent) to aid in the stirring of the various components. Once stirred, the mixture can be dried to remove the liquid carrier. The resulting dry mixture can then be subjected to mechanical stress (e.g., grinding), which breaks the mixture down into smaller particles that form the plurality of discrete particles of the powdered soap. Non-limiting examples of grinding include subjecting the dry mixture to a high-speed mixer, a Henschel mixer, or a Loedige mixer. After milling, a variety of discrete particles can be collected. In some embodiments, these particles may be screened to remove small or large particles unsuitable for powdered soap. In other embodiments, the particles are not screened. The resulting powdered soap can then be distributed into the reservoir of a soap dispenser. For example, the soap dispenser could be a bag, box, or other airtight container.
