摘要:
Described is a fragrancing composition having fragrancing components that are not activated until, e.g., application to the skin of a human. The composition is alkaline or (if anhydrous) capable of producing an alkaline pH when in contact with water, prior to application, and includes (1) a vehicle for application of the composition, and (2) at least one potential fragrance that is at least one compound having little or no odor in the alkaline composition but which, e.g., is hydrolyzed in a lower pH environment to produce compounds having a relatively strong aroma. Upon application of the alkaline composition to the skin surface, the strong buffering capacity of the skin (the surface of which has a normal pH of 5.5-7.0) neutralizes alkalinity of the composition (lowers pH) so as to restore normal skin surface pH; the potential fragrance is then hydrolyzed at the lower pH to release the compound having relatively strong aroma. The potential fragrance can be incorporated as a component of a transparent (clear) deodorant stick composition for application to human axillary regions, the fragrance being released after application to the body.
摘要:
The invention is directed to a cosmetic product comprising a powder/oil dispersion having high levels of cosmetic powder. More particularly, it is directed to an antiperspirant where at least part of the powder content is an astringent, such as aluminum chlorhydrate. By using one or more cationic or nonionic surfactants in an oily vehicle, a highly concentrated, stable dispersion having relatively low viscosity and creamy consistency, with a dry, non-oily feel is obtained.

The composition is alkaline or (if anhydrous) capable of producing an alkaline pH when in contact with water, prior to application, and includes (1) a vehicle such that when the composition is in contact with water, prior to application, the composition is at an alkaline pH; and (2) at least one potential fragrance that is at least one compound having little or no odor in the alkaline composition but which, e.g., is hydrolyzed in a lower pH environment to produce compounds having a relatively strong aroma. Upon application of the alkaline composition to the skin surface, the strong buffering capacity of the skin (the surface of which has a normal pH of 5.5-7.0) neutralizes alkalinity of the composition (lowers pH) so as to restore normal skin surface pH; the potential fragrance is then hydrolyzed at the lower pH to release the compound having relatively strong aroma.

摘要:
A package for a stick product, such as an antiperspirant stick, comprises a barrel for containing the stick, the barrel having an opening through which the stick can be exposed for use, and a product support member for supporting the end of the stick product opposite the end of the stick which is to be exposed. The support member is movable for adjusting the amount of the stick product which is exposed for use through the barrel opening. An applicator surface is provided about the periphery of the opening of the barrel for application and rubbing in of a visible amount of product. The package, including the applicator surface, allows the consumer to rub the product in while avoiding contacting the underarm with the relatively narrow edge of the barrel. The quantity of product being applied can also be accurately controlled using the package. The surface of the product support member has a configuration, in cross section, like that of the applicator surface adjacent the periphery of the opening, so that the product can be used to the bottom of the stick.
