Abstract
The invention, in part, relates to skin care or hair care compositions containing a source of carbon dioxide. The carbon dioxide is conveniently entrained in a gel-network, or liquid crystalline phase, immediately prior to skin or hair application. A substantial portion of the carbon dioxide will be lost from the product upon application to the skin or hair. However, a sufficient amount of carbon dioxide will remain in the product to stimulate oxygen flow to the outer layers of the skin with the apparent retardation of skin aging. The present invention also relates to the field of hair treatment and particularly to the removal of chemically bound residues and mineral deposits from hair. Hair may act as a sink for environmental minerals and heavy metals. In addition to undesirable changes in color and appearance, environmental minerals may have an adverse effect on chemical hair treatments. Mineral deposits in tap water may strip away highlights, darkening hair to a brassier hue. In both skin and hair care products, the liberated carbon dioxide also functions to facilitate the delivery of active or functional substances to keratinous substrates, such as skin and hair.
