Description
BACKGROUND
This application is directed to an improved cosmetic composition for use on the body.
Aging, along with environmental conditions, such as heating and air conditioning, exposure to the sun, and pollution, exert severe stress on the skin, resulting in dryness of the skin, accumulation of cellulite, wrinkles, and other cosmetically undesirable effects. Although a number of cosmetic compositions for use on the body already exist, there is a need for a simple to apply and effective cosmetic treatment that simultaneously provides multiple functions, including hydration, protection, and soothing of the skin, anti-free radical activity, along with anti-cellulite or firming activity, as appropriate. It is especially desirable that such a treatment can be prepared in alternative formulations that can be modified to meet the particular needs of each user.
SUMMARY

Homogenization mixing is then discontinued, and the mixture is pumped out into a stainless steel drum and covered; the mixture is stored in a hot room at 60.degree. overnight.
After the kettle used for Mixture V is cleaned, Mixture III (witch hazel, horsetail extract, ivy extract, chamomile extract, capsicum extract, vegetal amino complex, comfrey extract, Aloe vera gel, and the four types of microcapsules) is loaded into the kettle and mixed with sweep mixing until uniform. Mixture IV (carrageenan, xanthan gum, and 1,3-butylene glycol) is premixed in a separate container with a propeller mixer. Mixture IV is then added to Mixture III with vigorous mixing, and fast homogenization mixing with moderate sweep mixing is performed for approximately 90 minutes until the combination is smooth. The bottom of the kettle should be checked for complete dispersion. Homogenization mixing is then discontinued, and slow sweep mixing is continued until the end of the day. The combination of Mixtures III and IV is then allowed to sit in the kettle overnight. All these steps are to be completed on the first day of manufacture.
On the second day, Mixture V is removed from the hot room and mixed with a propeller mixer until homogenous; if the mixture is not completely melted, it is to be reheated to 60.degree.-65.degree. C. with propeller mixing.
Mixture V is then pumped into the kettle containing Mixtures III and IV. During pumping, slow speed homogenization mixing is performed. When pumping is complete, moderate sweep mixing and fast homogenization mixing are performed for 30-60 minutes until the combination of Mixtures III, IV, and V is smooth. Homogenization mixing is then discontinued.
Before being added, the combination of Mixtures I and II must be smooth, homogenous, and free of lumps. The combination of Mixtures I and II is then pumped into the kettle containing a combination of Mixtures III, IV, and V. Fast sweep mixing is performed for 60 minutes.
The batch is then run through a Gaulin homogenizer at a setting of 1000 psi into stainless steel drums. The kettle is then cleaned, and the batch is pumped into it.
Mixtures VI (the complex of phenoxyethanol, methylparaben, ethylparaben, propylparaben, and butylparaben) and VII (methylnicotinate) are added to the batch with moderate sweep mixing; mixing is continued for 30 minutes.
Mixture VIII (triethanolamine and demineralized water) is premixed and added to the batch. The batch is then mixed with sweep mixing at fast speed for 60 minutes until the batch is homogeneous.
Mixture IX (fragrance) is then added to the batch kettle with sweep mixing at moderate speed until the batch is uniform. At this point, sweep mixing is to be discontinued completely. The batch is then dropped from the kettle into tightly sealed stainless steel drums and stored in the cold room.
ADVANTAGES OF THE INVENTION
Cosmetic compositions according to the present invention simultaneously provide totally comprehensive hydrating, protecting, soothing, and anti-free radical activity, plus firming or anti-cellulite activity, or both, according to the microcapsules used in the particular composition. The use of microcapsules provides for long term sustained release of the active ingredients, giving significantly longer duration of activity. The use of both hydrophilic and lipophilic microcapsules provides comprehensive moisturizing, addressing both water and lipid shortages of the skin. Most moisturizers address water shortage, some address lipid shortage, but so far no one has addressed both using a slow release, long term mechanism for addressing both. This is accomplished together with providing firming, anti-cellulite and anti-free radical effects in some formulations where necessary.
Although the present invention has been described in considerable detail with regard to certain preferred versions thereof, other versions are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the preferred versions contained herein.
