Problems solved by technology

However, one problem with multiphase compositions is that one phase may flow more freely than the other when the fluids, especially when the phases forming the composition have different rheological properties (such as different viscosities), which means Over time (under static conditions or in motion) one phase may move relative to another within the vessel
In addition, altering the viscosity of one or more phases may adversely affect the skin feel of multiphase compositions after application

Embodiment approach

[0104] According to another embodiment, the colorant comprises titanium oxide, preferably a titanium dioxide (INCI name) with a name Flamenco Summit Gold Y30D (INCI Name: Mica (and) titanium dioxide) and / or coated with perfluoroalkyl phosphate Titanium dioxide, especially by Daito Kasei Kogyo, name PF5TIO 2 A 100 Sales (INCI Name: Titanium Dioxide (and) C 9 C-C 15 Fluorogenate) and iron oxide coated or uncoated.

[0105] The term "pearl mother" is understood to mean any shape, rainbow-colored or other colored particles, especially from some of the shells in their housings or additional color effects by optical interference.

[0106] Examples of pearl mother include pearl pigments such as mica titanium coated with an oxide, coated mica-chloride, coated mica titanium, based on chloride-based pearl pigment. They may also be mica particles, and at least two continuous layers of metal oxide and / or organic colored substances are superimposed on the surface.

[0186] Use the following method to make a cream phase: in the main vessel, the oil phase component (C 12 -C 15 Alcohoidate, white soft paraffin BP, Abil WE09, Abil EM90 and isopenyl oxides) are combined by stirring at 55 ° C to 60 ° C. In the support vessel, the aqueous component (water, SEQUESTREN, magnesium sulfate BP superparis, preservative, BitRex solution Macfs and moistrid) is combined between 55 ° C to 60 ° C for one to two minutes by stirring. Then, the contents of the support vessel and the main vessel content are slowly combined with the main vessel content, and Water-Pool is not produced. The main vessel content was then cooled to 25 ° C, and then at a minimum of 3500 rpm for 1 minute. Finally, the mixture was carried out for 5 minutes.

[0188] Example 2 - Viscosity Determination

[0189]Determine the viscosity of the gel phase and the cream phase. The viscosity as described in this application is measured using a Cabs RVDV-I Prime viscosity measuring model G experimental table, which is equipped with Heliopath and TBAR rotor C (also known as rotor 93) or condensate for the cream phase. The TBAR rotor B (also known as the rotor 92) is also known as the phase. The viscosity measurement is obtained as follows: (1) Make sure the sample product has a temperature of 23 ° C and is not inflated. The sample exists in a plastic container of 120 ml of capacity; (2) Before the measurement is measured, no rotor is attached to the viscometer, follow the instructions on the screen, automatically zero the viscometer, (3) Select the TBAR rotor C (For cream phase) or TBAR rotor B (for gel phase); (4) Select the rotational speed "10". This will rotate the rotor 10 revolutions per minute; (5) Carefully attach the rotor to the lower...

Abstract

According to the present invention there is provided a multi-phase, fluid skincare composition comprising (a) at least one cream phase; and (b) at least one gel phase; wherein the cream phase and the gel phase are visually distinct phases that are packaged in physical contact; wherein the viscosity ratio of the cream phase to the gel phase is 1.25 or greater: 1 or 1:1.25 or greater, preferably 1.25 or greater: 1; wherein the viscosity of the cream phase is at least 15 Pa-s; wherein the viscosity of the gel phase is at least 10 Pa-s; wherein the cream phase and the gel phase are present in the composition at a level such that the weight ratio of cream phase to the gel phase is within the range of from 65:35 to 35:65; and wherein the viscosity is measured at 23 DEG C. The present invention also provides a collapsible tube having an outlet bore and containing the composition as defined above, wherein the tube is filled such that, when the composition is extruded from the outlet bore, the extruded composition comprises the cream phase and the gel phase that are visually distinct from one another and within a weight ratio of the cream phase to the gel phase of between 65:35 and 35:65 across the cross-section of the extrusion. The present invention also provides a use of the composition defined above for the purpose of one or more of moisturising the skin, including hydrating the skin, improving the radiance of the skin, improving skin suppleness, reducing skin tightness, nourishing skin and / or reducing dryness. The present invention also provides a use of the composition defined above for the purpose of topical application to any one or more of the face, the neck skin and / or the decollete, preferably the face.

Description

Technical field [0001] The present invention relates to a multiphase, a fluid skin care composition comprising a visually different and has a different viscosity of a cream phase and a gel phase, thereby stable during transportation and dispensing during transportation during transportation. . Background technique [0002] One common problem when formulating skin care compositions is how to combine incompatible ingredients. Although such problems can be solved by packaging that includes separate chambers, it may be difficult to manufacture such packaging, which typically requires more original packaging materials that may affect the environment, and not always The composition is delivered in a manner expected by consumers. [0003] Another solution to this problem is to develop multiphase compositions, wherein an incompatible component forms a portion of a phase, and other incompatible components form a portion of further visually different phases. However, when the fluid, especi...
