COSMETIC COMPOSITIONS COMPRISING A TALC PARTICULATE
Cosmetic compositions comprising a talc particulate which is used in the cosmetic composition as a colour booster, coverage enhancer, opacity enhancer, cohesion enhancer and/or crack prevention additive.
1 . A cosmetic composition comprising a talc particulate having a d 50laser of at least about 5.0 μm and a lamellarity index of at least about 1.0,
wherein the talc particulate comprises less than about 20% aluminium, based on the weight of the talc particulate.
2 . A cosmetic composition for application to human skin, said cosmetic composition comprising
a colourant and
a colour boosting amount of a talc particulate,
wherein the talc particulate boosts the colour of the cosmetic composition
(i) such that a lower amount of the cosmetic composition may be applied to any given surface area of the skin without loss of colour, and/or
(ii) such that the colour density of the cosmetic composition is boosted compared to the cosmetic composition absent the talc particulate, and/or
(iii) a lower amount of colourant may be used without loss of colour density compared to the cosmetic composition absent the talc particulate.
3 . A method for modifying the visual appearance of a facial feature, comprising applying, to the facial feature, a cosmetic composition comprising colourant and a colour boosting amount of a talc particulate.
4 . A method according to claim 3 , wherein the presence of the colour boosting amount of the talc particulate boosts the colour such that
(i) a lower amount of the cosmetic composition may be applied to any given surface area of the facial feature without loss of colour, and/or
(ii) a lower amount of colourant may be used without loss of colour density.
5 . (canceled)
6 . A cosmetic composition according to claim 1 , wherein the cosmetic composition is a cohesion enhancer.
7 . A pressed powder cosmetic comprising the cohesion enhancer of claim 6 .
8 . (canceled)
9 . A powdered cosmetic compact comprising the cosmetic composition of claim 1 .
10 . A pressed powder cosmetic comprising a crack prevention additive, wherein said crack prevention additive comprises the cosmetic composition of claim 1 .
11 . (canceled)
12 . The pressed powder cosmetic of claim 10 , wherein the powdered cosmetic compact is manufactured by a wet pressing method, and wherein: the talc particulate is uncoated or the pressed powder cosmetic comprises an on-based binder.
13 . A method for preventing cracking of a pressed powder cosmetic, the method comprising incorporating a talc particulate in slurry form in a pressed powder cosmetic compact precursor, and wet processing said precursor to produce a pressed powder cosmetic.
14 . A pressed powder cosmetic comprising the cosmetic composition of claim 1 , wherein the cosemic composition is a colour booster, cohesion enhancer and crack prevention-additive.
15 . A cosmetic composition comprising a coverage and/or opacity enhancer, wherein said coverage and/or opacity enhancer comprises the cosmetic composition of claim 1 .
16 . A cosmetic composition for application to human skin according to claim 2 , wherein the talc particulate has a d 50laser of at least about 5.0 μm, a lamellarity index of at least about 1.0, and an aluminium content of less than about 20%, based on the weight of the talc particulate.
17 . A cosmetic composition for application to human skin according to claim 16 , wherein the cosmetic composition is a foundation or concealer.
18 . (canceled)
19 . A cosmetic composition for application to human skin according to claim 16 , wherein the coverage and/or opacity enhancer is present in amount sufficient to provide: (i) full coverage when applied to human skin, and/or (ii) an opacity of at least about 70%.
20 . A cosmetic composition according to claim 1 , wherein the talc particulate has a d 50laser of at least about 10.0 μm, a lamellarity index of at least about 1.0 and an aluminium content of less than about 10%, based on the weight of the talc particulate.
21 . A cosmetic composition according to claim 1 , wherein (i) the talc particulate has a lamellarity index of at least about 2.0, and/or (ii) the talc particulate has an aluminium content of no greater than about 5%.
22 . A cosmetic composition according to claim 1 , wherein the talc particulate is surface treated.
23 . (canceled)
24 . (canceled)
25 . A cosmetic composition according to claim 20 , wherein wherein the talc particulate is a surface treated talc particulate.
26 . A cosmetic composition according to claim 25 , wherein the talc particulate has a d 50laser of at least about 10.0 μm and wherein the talc particulate comprises less than about 10% aluminium, based on the weight of the talc particulate.
