Embodiment 1

[0079] (Gel-based sugar scrub)

[0080] Table 1 provides non-limiting examples of gel-based sugar scrubs of the present invention. It was found that the use of surface-treated silica (silylated silica) and polyethylene glycol produced a gel matrix, which compared to what was originally expected to allow a large amount of sugar to be present in the matrix. Without wishing to be bound by theory, it is believed that the silylated silica helps to keep the sugar suspended throughout the gel matrix. The dispersion remained stable under the conditions of the stability test (no coalescence or "clumping" of sugar). The remaining ingredients provide tactile and rheological properties to the gelled dispersion. It is worth noting that the stable dispersion is substantially oil-free (e.g., less than 5 wt% oil, preferably 2 wt% or less oil, oil such as jojoba ester).

Description

[0001] Cross references to related applications [0002] This application claims the rights of U.S. Provisional Patent Application No. 62 / 090630 filed on December 11, 2014, titled "Gel-based Sugar Scrub". The entire content of the cited application is incorporated herein by reference without waiving the rights. [0003] Background of the invention [0004] A. Field of invention [0005] The present invention generally relates to oil-free sugar scrubs, which can be used to exfoliate, cleanse or moisturize skin. Sugar scrubs consist of a gel with granulated or granulated sugar evenly dispersed throughout the gel matrix. [0006] B. Background technology [0007] Several skin moisturizing and / or exfoliating compositions containing sugar or other exfoliants are currently available. These compositions have various disadvantages: unpleasant tactile properties (for example, heavy, greasy or sticky), instability problems, skin irritation problems, or insufficient moisturizing ability.
