[0073] Combine the ingredients of Phase A using a homogenizer to mix and sieve the colloidal magnesium aluminum silicate into the water. Start heating the water to 75C. Mixing was continued for 20 min at 75C. Then turn off the heat. Add phase B components to phase A, one at a time, as phase A / B continues to cool. When the temperature reaches about 5OC, add phase C while continuing to mix. Mix for 2-3 hours to ensure homogeneity, then pour into containers.

Abstract

A treatment composition for treating human skin that has one or more particulate suspending agents in a concentration of from about 0.05% to about 2.0%, by weight, and one or more film forming polymers in a concentration of from about 0.1% to about 5.0%, by weight. Further, particles in a concentration of from about 1.0% to about 20.0%, by weight; one or more humectants in a concentration of from about 2.0% to about 20.0%, by weight; and, water are provided. The treatment compositions of this invention are used in an applicator having an applicator head having one or more applicator nozzles which may be in a array. The apparatus further has a reservoir containing the treatment composition, a sensor, and a CPU. The sensor takes an image of at least 10 mum2 of skin, the CPU analyzes the image to calculate one or more localized L values of individual pixels or group of pixels of the skin. Then the CPU compares the local L value to a predetermined background L value to identify skin deviations. A skin deviation occurs where the difference between the background L value and the local L value is greater than a predetermined Delta LS value.

Description

technical field [0001] The present invention relates to devices for applying compositions to skin and other keratinous surfaces. The composition can change the color or structure of the keratinous surface. Background technique [0002] There are several reasons for the difference in tone on human skin. Acne, freckles, sun damage and age spots are just some of the common causes of visible imperfections on the skin. Textural differences such as fine lines, wrinkles and scars are also well known. Differences in tone and texture are both noticeable and highly noticeable to the human eye, even if these differences are small. It is known that large areas of skin over and around these differences can be covered with makeup or other concealers. [0003] Furthermore, attempts have been made to more precisely and topically apply compositions that conceal or mask differences in the skin. Hand-held devices that move over the skin have been developed to apply skin treatment composit...
