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, adding a binder such as water and a non-ionic surfactant, and grinding it into a powder using a high-speed mixer. To increase solubility, the water content of powdered soaps prepared in this way is usually kept at approximately 7 to 15%. However, such powdered soaps have poor flowability and / or feel. Therefore, these powdered soaps are preferable only when used as laundry detergents requiring high solubility and can be dispensed 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 pleasant feel while maintaining solubility, making the powdered soap suitable for personal care applications.

Other embodiments of the present invention include a powder soap comprising a plurality of particles, each of the particles comprising: a cationic polymer; a clay; and a fatty component; wherein the plurality of particles has a d77 value of 840 microns. Other embodiments of the present invention include a method for forming a hand soap / body soap / hair soap, the method comprising a) forming a mixture of a polyquat, a clay, and a fatty component; and b) processing the mixture into a plurality of discrete particles.

According to some embodiments, the mixture may further comprise one or more liquid carriers (e.g., water, non-aqueous solvent) to aid in stirring 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), thus separating the mixture into smaller particles that form the plurality of discrete particles of 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, the plurality of discrete particles can be collected.

EXAMPLES A first experiment was conducted to test the dissolving performance of the soap granules of the present invention. The first experiment included soap granules of four different formulations, as shown below in Table 1. Table 1 ινΐΛ / a / zuzz / uu / Comp. Ex. 1 Ex. 1 Ex. 2 Ex. 3 % by weight Clay - 0.05-0.25 0.1-0.5 0.1-1 Polyquaternium - 0.1-1 0.1-1 0.1-1 Fat component 99.9 % by weight 98.5-99.5 98.5-99.5 98-99 Titanium dioxide 0.1% by weight 0.05-0.25 0.05-0.25 0.05-0.25 Each formulation was then processed into particles that have a size distribution as shown in Table 2. Table 2 iviA / a / zuzz / uu i ym Particle Percentage Particle Size 10% > 1.4 mm 77% 0.84 mm to 1.4 mm 10% 0.5 mm to <0.84 mm 0.4% 0.29 mm to <0.5 mm 0.6% < 0.29 mm The particles from each compound, Example 1 and Examples 1-3, were then subjected to a dissolution test. Equal amounts of each compound were hand-shaken while exposed to constant amounts of tap water, simulating a handwashing exercise. Each compound included a total of ten (10) samples, and the samples for each compound were averaged to provide a final ranking of how each formulation performed in the dissolution test. The rankings for each compound are tabulated below in Table 3. Table 3 Comp. Ex. 1 Ex. 1 Ex. 2 Ex. 3 Dissolution Passing Score 40% 50% 70% 50% Dissolution Rank 4th 2nd (tied with Ex. 3) 1st 2nd (tied with Ex. 1) Sensation / Conditioning Passing Score 60% 50% 70% 70% Sensation / Conditioning Rank 3rd 4th 1st (tied with Ex. 3) 1st (tied with Ex. 2) As the data described in Table 3 (above) demonstrate, the addition of a clay and a polyquat resulted in better dissolution rates, with Examples 1-3 dissolving at faster rates than Comparative Example 1. However, the mere presence of clay alone did not result in superior dissolution rates, as it was surprisingly found that the fastest dissolution rates occurred closer to 0.25 wt% clay, with dissolution rates decreasing as the amount decreased (approximately 0.1 wt%) or increased (approximately 0.5 wt) relative to the 0.25 wt% amount.Additionally, it was surprisingly discovered that with the amounts of polyquat and clay in Example 2, the best feel and conditioning performance for the powdered soap was also obtained, thus providing an unexpected synergy between the presence of clay and polyquat in the powdered soap composition.
