Description
The present invention relates to new cream oxter compositions, said composition contains structure wax material.Especially, the present invention relates to the antiperspirant deodorant compositions that the part is used for human body skin, said composition contains structure wax, clay and shelters oil.
The underarm composition of known local usefulness contains for example polysiloxane of non-volatile polysiloxane fluid, and described polysiloxane fluid makes compositions have lubrication, and the solid that exists in the compositions is had masking action.Described solid example comprises hidroschesis active matter matter.The effect of said composition can not be subjected to having a strong impact on of non-volatile polysiloxanes.The example of described compositions is seen EP 28853 (Procter ﹠amp; Gamble company).
Known some the alkylsiloxane wax that in underarm composition, also comprises.That EP 549223 (DowCorning) has described is bar-shaped, walk pearl and spraying uses underarm composition, said composition to contain some chain alkyl silicone waxes.It is said that this wax provides required characteristic for prescription, for example the hardness of Gai Shaning, contrast (reduced) brighten, improve dermal sensation and with the compatibility of other components.
Our common unsettled UK Patent Application 9506039.8 has been described the Arrcostab siloxane wax and has been used to improve the sense quality of underarm composition such as the purposes of dermal sensation.
The prescription of above-mentioned prior art has been described suspension composition, and said composition is preferable over known emulsion compositions usually, has found that known emulsion compositions produces undesirable dermal sensation, for example sticking or wet sensation.Suspending agent can make flour for example the antiperspirant active composition be suspended in effectively in the compositions to improve the bin stability of its effect and compositions.
But many suspensions of prior art have caused other for example frosted senses of unhappy sensation to skin, and have caused the visible deposition on skin and fabric in the sensation of improving some aspect of skin (for example reducing wet sensation).
In order to address this problem, EP 135315 (Mennen company) has described no clay antiperspirant products, and this product contains Y 7175 and gellant.Yet, lack deflocculating agent and can make product, and viscosity reduces, and that the reduction of viscosity is a cream is undesirable at high temperature and long-time still unstable down.
