Abstract
Abstract A dual-phase toilet bar is provided having a first portion that is at least translucent and a second portion that is opaque.Each portion of the bar has at least 80% by weight of its components identical. The opaque portion incorporates a solid particulate opacifying agent. A process is also disclosed wherein a clear composition is poured into a mould to partly fill same. Thereafter, an opaque composition is poured into the remaining volume of the mould, this composition being essentially identical to the clear composition but also including a small amount of solid particulate opacifying agent. Alternatively the opaque composition may be poured first into the mould followed by the clear composition. <IMAGE>

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
68 words
A dual-phase toilet bar comprising: (i) a first portion that is at least translucent; and (ii) a second portion that is opaque, said second portion achieving opacity through incorporation of from about 0.01 to about 10% of a particulate opacifying agent, the first and second portions having at least 90% by weight of their ingredients being identical and joining one another only along a single curvilinear shaped surface.
Claim 2
Dependent Claim
68 words
A dual-phase toilet bar comprising: (i) a first portion that is at least translucent; and (ii) a second portion that is opaque, said second portion achieving opacity through incorporation of from about 0.01 to about 10% of a particulate opacifying agent, the first and second portions having at least 90% by weight of their ingredients being identical and joining one another only along a single curvilinear shaped surface.
Claim 3
Dependent Claim
27 words
The bar according to claim 1 wherein at least 99% by weight of the ingredients of the first portion are identical to those of the second portion.
Claim 4
Dependent Claim
28 words
The bar according to claim 1 wherein the solid opacifying agent is selected from the group consisting of titanium dioxide, alumina, zinc oxide, calcium carbonate and combinations thereof.
Claim 5
Independent Claim
172 words
A method for preparing a toilet bar formed at least 30% thereof with a clear first portion and at least 30% thereof with an opaque second portion, said portions adjoining one another only along a single curvilinear shaped surface, the method comprising the steps of: (i) preparing a clear soap composition; (ii) pouring said clear soap composition into a mold to fill said mold to a level no higher than 90% of its capacity thereby forming said clear first portion; (iii) pouring a second soap composition into said mold onto said clear first portion at a time when said poured clear first portion has maturated to a level just short of hardening, said second soap composition being opaque having at least 80% by weight of its ingredients identical to that of said clear soap composition, and additionally including from about 0.5 to about 10% by weight of a solid opacifying agent thereby forming said opaque second portion; and (iv) cooling and hardening the clear and opaque portions to obtain said toilet bar.
Claim 6
Independent Claim
172 words
A method for preparing a toilet bar formed at least 30% thereof with a clear first portion and at least 30% thereof with an opaque second portion, said portions adjoining one another only along a single curvilinear shaped surface, the method comprising the steps of: (i) preparing a clear soap composition; (ii) pouring said clear soap composition into a mold to fill said mold to a level no higher than 90% of its capacity thereby forming said clear first portion; (iii) pouring a second soap composition into said mold onto said clear first portion at a time when said poured clear first portion has maturated to a level just short of hardening, said second soap composition being opaque having at least 80% by weight of its ingredients identical to that of said clear soap composition, and additionally including from about 0.5 to about 10% by weight of a solid opacifying agent thereby forming said opaque second portion; and (iv) cooling and hardening the clear and opaque portions to obtain said toilet bar.
Claim 7
Dependent Claim
27 words
The method according to claim 4 wherein at least 99% by weight of the ingredients of the first portion are identical to those of the second portion.
Claim 8
Dependent Claim
28 words
The method according to claim 4 wherein the solid opacifying agent is selected from the group consisting of titanium dioxide, alumina, zinc oxide, calcium carbonate, and combinations thereof.
Claim 9
Independent Claim
177 words
A method for preparing a toilet bar formed at least 30% thereof with a clear first portion and at least 30% thereof with an opaque second portion, said portions adjoining one another only along a single curvilinear shaped surface, the method comprising the steps of: (i) preparing a clear soap composition; (ii) preparing an opaque soap composition, said opaque soap composition having at least 80% by weight of its ingredients identical to that of said clear soap composition, and additionally including from about 0.5-10% by weight of a solid particulate opacifying agent; (iii) pouring said opaque soap composition into a mold to fill the mold to a level no higher than 90% of its capacity thereby forming said opaque second portion; (iv) pouring said clear soap composition into said mold onto said opaque second portion at a time when said opaque second portion has maturated to a level just short of hardening, said clear soap composition thereby forming said clear first portion; and (v) cooling and hardening the first and second portions to obtain the toilet bar.
Claim 10
Independent Claim
177 words
A method for preparing a toilet bar formed at least 30% thereof with a clear first portion and at least 30% thereof with an opaque second portion, said portions adjoining one another only along a single curvilinear shaped surface, the method comprising the steps of: (i) preparing a clear soap composition; (ii) preparing an opaque soap composition, said opaque soap composition having at least 80% by weight of its ingredients identical to that of said clear soap composition, and additionally including from about 0.5-10% by weight of a solid particulate opacifying agent; (iii) pouring said opaque soap composition into a mold to fill the mold to a level no higher than 90% of its capacity thereby forming said opaque second portion; (iv) pouring said clear soap composition into said mold onto said opaque second portion at a time when said opaque second portion has maturated to a level just short of hardening, said clear soap composition thereby forming said clear first portion; and (v) cooling and hardening the first and second portions to obtain the toilet bar.
Claim 11
Dependent Claim
