ABSTRACT:

FIELD OF THE INVENTION
The present invention relates generally to a cream base for use in a variety of cosmetic compositions. More particularly, the present invention relates to a cream base that has a powdery finish and feel when applied to the skin. This cream base is preferably used to deliver fragrance, more preferably microencapsulated fragrance, to the skin.
BACKGROUND OF THE INVENTION
Various cosmetic base compositions are known in the art, including powders, lotions, gels, sticks and creams. While the lines of demarcation between these types of base compositions are at times inexact, each type is seen by consumers as having different positive and negative attributes. For example, powders are often viewed as drying and hard to control. Lotions can be perceived as overly wet, requiring time to dry, and can also be perceived as greasy or oily. Creams can be seen as excessively heavy. Thus, a demand exists for products that combine the positive attributes of more than one such cosmetic base, without the perceived limitations. Certain such products have been commercialized, including “dry lotions”. However, no product is known that successfully provides a creamy base that has good payoff and leaves a silky, powdery finish when applied to the skin.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a cosmetic cream base composition that leaves a silky, powdery finish when applied to the skin.
It is another object of the present invention to provide such a cosmetic cream base that has good payoff, namely in releasing a proper amount of product (sufficient but not excessive) to the applicator when light pressure is applied to the cosmetic by the applicator.
It is a further object of the present invention to provide such a cosmetic cream base that is suitable for delivery of microencapsulated fragrance to the skin.
It is still another object of the present invention to provide a cosmetic cream base that is suitable for delivery of other cosmetic ingredients, such as treatment agents and non-microencapsulated fragrances, to the skin.
Accordingly, the present invention is a cream composition that includes about 10 to about 30 weight percent of a wax component having ozokerite, myristyl myristate, petrolatum, and hydrogenated castor oil; about 30 to about 50 weight percent of a powder component having a starch selected from the group consisting of corn starch, oat starch and combinations thereof; and a volatile component having a volatile selected from the group consisting of cyclomethicone, isoeicosane and combinations thereof. The cream composition preferably includes a microencapsulated fragrance.
