摘要:
Disclosed is a solid cosmetic composition (e.g., a cream composition) containing an active cosmetic material (e.g., a deodorant active, an antiperspirant active, a sunscreen, an insect repellent and/or an anti-fungal agent) and a silicone gel material. The silicone gel material includes (a) a volatile silicone material and (b) an organopolysiloxane material as a gelling agent, able to form a gel after being mixed with the volatile silicone material. The organopolysiloxane material can be a reaction product of a vinyl-terminated siloxane polymer and a hydride cross-linking agent. The composition can be formed by mixing the active cosmetic material and silicone gel material at ambient temperature. The compositions do not need particulate or clay thickeners or waxy gelling agents.
摘要:
A method for forming a diffuse visual pattern of two or more product components in a container. The method includes providing a filler/mixer having a mixing chamber with up to about 10 mixing elements. A container is positioned after the mixing chamber on a container support that is capable of rotating the container. The components are fed into the mixing chamber to form a mixture. The mixture is fed into the container while it is rotated and concurrently separated from the mixing chamber.
摘要:
A dispenser (100) having a reservoir (210) containing a composition (211) comprising a first substance (220) and at least one bead (230) immersed in the first substance, the bead comprising a shell (231) containing a second substance (232); a dispensing conduit (320) for dispensing the composition from the reservoir; and a rupture member (330) disposed within the dispensing conduit, the rupture member comprising at least one aperture (331 A-C) and at least one barb (332) extending into the aperture, the at least one barb rupturing the shell of the at least one bead as the composition flows through the at least one aperture.
摘要:
Described are methods for preparing compositions that include the steps of (a) premixing a cationic guar gum in water; (b) adding a surfactant component to the premix of (a); (c) adding about 1 to about 3 weight % of salt to the mixture obtained in (b); (d) applying shear to the mixture obtained in (c) at a shear rate not exceeding about 20 sec−1 to form a spherulite composition; and (f) mixing an oil phase with the spherulite composition. Also included are compositions prepared by this process.
