Description

Composition comprising thermoplastic hollow particles

Technical Field

The present invention relates to a composition for an aerosol, preferably a cosmetic composition, and more preferably a skin cosmetic composition, comprising thermoplastic hollow particles for keratin materials such as the skin.

Background

Cosmetic compositions, such as skin care and make-up compositions having matte effect properties, are commonly used to address the problem of shine caused by excess sebum and to improve the long-term staying power of make-up, such as that provided by the composition, as make-up has a tendency to deteriorate visually over the course of a day. They give the skin a dull appearance, due to the ability to scatter light on the skin surface. They can also be used to lighten skin imperfections such as micro-scars (microreliefs), wrinkles, fine lines and pores or color changes.

Conventional compositions, known as matt-effect compositions, usually contain powders which absorb sebum (see WO 2004/000212 or JP-T-2005-529976). Among the matt powders of natural or synthetic origin which may be mentioned are in particular fillers such as talc, starch, mica, silica, nylon powder and poly (methyl methacrylate). This type of filler has the disadvantage of not imparting a natural or transparent appearance by imparting a powdered or even plaster-like appearance to the skin and aggravating skin imperfections. In addition, if the composition includes an oil or oily component, the matte effect provided by the powder is often worsened.

Some conventional matte effect compositions may be provided in the form of an aerosol with a spray device. However, sebum absorbing powders in matte effect compositions may clog the nozzle of the spray device. If the composition includes an oil or oily component, the nozzle may be easily clogged with powder that may aggregate with the oil or oily component that may be used as a binder.

TABLE 1

Comparative examples 1 to 7

The following compositions according to comparative examples 1 to 7 shown in Table 2 were prepared by mixing the ingredients shown in Table 2. The numerical values of the amounts of the ingredients shown in table 2 are all based on "wt%" as the active material.

TABLE 2

Comparative examples 8 to 14

The following compositions according to comparative examples 8 to 14 shown in Table 3 were prepared by mixing the ingredients shown in Table 3. The numerical values of the amounts of the components shown in table 3 are all based on "wt%" as an active material.

TABLE 3

[ evaluation ]

The compositions according to examples 1 to 3 and comparative examples 1 to 14 were evaluated as follows.

(Matt)

Each of the compositions according to examples 1 to 3 and comparative examples 1 to 14 was applied to a substrate sheet (comparative card) so that the composition formed a layer having a thickness of 100 μm. After leaving the substrate at room temperature for 24 hours, the gloss intensity was measured with a gloss meter (CM-2600 d, Konica Minolta) at a reflection intensity of 60 degrees at an incident angle. The gloss intensity is classified according to the following criteria.

High: <50

The method comprises the following steps: 50-80

Low: >80

The results are shown in tables 1 to 3.

(transparency)

Each of the compositions according to examples 1 to 3 and comparative examples 1 to 14 was applied to a transparent PET sheet (BYK sheet) so that the composition formed a layer having a thickness of 25 μm. After leaving the substrate at room temperature for 24 hours, the light transmittance (%) was measured with a transparence meter (BYK guard ner Hazeguard plus, Toyo Seiki). The light transmittance was classified according to the following criteria.

High: >90

The method comprises the following steps: 90-85

Low: <85

The results are shown in tables 1 to 3.

(results)

The compositions according to examples 1-3 comprising thermoplastic hollow particles (acrylonitrile/methyl methacrylate/vinylidene chloride copolymer) are capable of providing excellent matt and transparent appearances, although they comprise an oil (isononyl isononanoate). Thus, the compositions according to examples 1 to 3 were found to have good cosmetic properties, in particular for the skin. In addition, it can be understood from examples 1 to 3 that even a small amount of thermoplastic hollow particles can provide excellent matte and transparent appearance.

The compositions according to comparative examples 1 to 4, 7 and 10 to 12 respectively comprised polymethylsilsesquioxane, methyl methacrylate crosspolymer, Nylon-12, synthetic wax, boron nitride, silica (and) polydimethylsiloxane and kaolin, instead of the thermoplastic hollow particles of examples 1 to 3, and therefore, the compositions according to comparative examples 1 to 4, 7 and 10 to 12 could not provide excellent matte effect.

The compositions according to comparative examples 5, 6, 8 and 9 respectively include corn starch, trimethylsiloxysilicate, silica and silica silylate, instead of the thermoplastic hollow particles of examples 1 to 3, and thus, the compositions according to comparative examples 5, 6, 8 and 9 can provide some matte effect. However, the compositions according to comparative examples 5, 6, 8 and 9 provided less matte effect than the compositions according to examples 1 to 3.

The composition according to comparative example 13 includes titanium dioxide instead of the thermoplastic hollow particles in examples 1 to 3, and thus the composition according to comparative example 13 cannot provide transparency.

The composition according to comparative example 14 included zinc oxide instead of the thermoplastic hollow particles of examples 1 to 3, and therefore, the composition according to comparative example 14 provided matte and transparency inferior to those provided by the compositions according to comparative examples 1 to 3.

[ spray test ]

The compositions according to examples 1-3 were spray tested using a conventional spray apparatus.

Each composition according to examples 1-3 (30%) was mixed with n-butane (70%) as propellant. The mixture was filled into a container. The container is then mounted in an aerosol device such that the nozzle of the device is connected to the container by a tube. Specifically, one end of the tube is connected to a nozzle and the other end of the tube is immersed in the mixture of the composition and propellant in the container.

The composition is discharged from the aerosol device as an aerosol by being ejected from the nozzle. After 30 seconds of spraying, the nozzle was not clogged.

The composition is discharged from the aerosol device as an aerosol by spraying from a nozzle, as above, for 1-3 months per day. The nozzle was not clogged.
