The present invention relates to a particle containing cellulose or a cellulose derivative as a main component, which comprises having a wrinkle-like or fold-like uneven structure on a surface thereof, a method for producing the same, and cosmetics containing said particles.
Porous fine particles have been used in a wide range of fields as various kinds of additives such as abrasives, matting agents (light diffusing agents), carriers, water absorbing materials, fillers, anti-blocking agents, etc., depending on the material, shape, physical properties, etc.
Among porous fine particles, microbeads generally refer to fine particles (particles having several μm to several hundred μm) made of plastics such as polyethylene, polypropylene, etc., and have widely been used for perfumery such as toiletry products (for example, face wash, body wash), oral care products (for example, dentifrices), cosmetics (for example, foundation), etc. Specifically, microbeads have been used as a scrubbing agent to enhance a massage effect and a cleaning effect in toiletry products such as face wash, body wash, etc., and in cosmetics such as foundation, etc., for example, they are used for developing a defocus effect (also referred to as a soft focus effect) that scatters reflected light in multiple directions, and corrects defects of skins such as spots, wrinkles, freckles, color unevenness, and the like (for example, see Patent Documents 1 and 2).
However, in recent years, it has been feared that microbeads pass through sewage treatment and flow out into rivers and oceans, and are taken up by living organisms to adversely affect the ecosystem. Since it is almost impossible to collect the microbeads once they flow into the environment, it has been required to replace the microbeads made of plastics with an environment-friendly material such as biodegradable plastic, a natural material, etc. As such a material, for example, porous resin fine particles containing a polyester-based thermoplastic resin having biodegradability as a main component have been reported (for example, see Patent Document 3). Also, as microbeads derived from natural materials, cellulose particles have been known (for example, see Patent Document 4).
However, since existing cellulose particles are hard and inferior in light scattering property, further improvement of these properties has been demanded for use in perfumery. That is, an object of the present invention is to provide a cellulose particle which is a natural material and is soft, and has excellent light scattering properties.
As a result of intensive studies by the present inventors, they have found that particles obtained by spray-drying a dispersion liquid of cellulose or a cellulose derivative, in particular, plant-derived cellulose nanofiber is appropriately suppressed in crystallization degree, and has a wrinkle-like or fold-like uneven structure on a surface thereof so that it is soft and excellent in light scattering properties and oil absorption properties, whereby the present invention has been completed. The present invention is as follows.
The particle of the present invention is appropriately suppressed in the crystallization degree, and has a wrinkle-like or fold-like uneven structure on the surface thereof, so that it is soft and is suitable for adding to cosmetics that comes into direct contact with skin. In particular, the particle of the present invention is excellent in oil absorption properties, so that it is suitable for adding to cosmetics containing an oily component(s) and an oily base(s), and it has also excellent optical characteristics (light scattering properties) that the incident light is uniformly light scattered, so that it can be expected to exhibit a defocus effect (also called a soft focus effect) by formulating it into cosmetics such as a foundation, etc.

A particle diameter of the particles of the present invention can be appropriately set depending on the desired use of the particles and, for example, it is distributed in the range of 0.5 to 500 preferably in the range of 1 to 200 more preferably 2 to 100 and particularly preferably in the range of 5 to 80 and an average particle diameter is, for example, in the range of 5 to 40 and preferably in the range of 5 to 30 Incidentally, in the present invention, the particle size means a value measured by a scattering type particle diameter distribution measurement device, and an average particles diameter means an arithmetic mean diameter calculated from the obtained particle size distribution.
In another aspect, the particles of the present invention are characterized in that a light scattering rate represented by the following formula (1) is in the range of 50 to 200%.
{in the formula (1), the reflection intensities at angles of 20°, 70° and 5° mean intensities of the reflected light at angles of 20°, 70° and 5° of a light receiver when light is incident from a certain angle after setting the sensitivity of the light receiver is set to an arbitrary value (which is referred to as a sensitivity adjustment value) when light is incident on particles at an angle of -30° with the normal direction to the partice being 0°. }
Here, the light scattering rate is calculated in accordance with the above-mentioned formula (1) described in WO 2010/092890. For example, when the light scattering rate at the incident angle of light is −30° is to be calculated, first, the normal direction of the surface against which the sample is pressed is 0°, and after the sensitivity of the light receiver at the time of incident of light to the sample from an angle of −30° is set to be an arbitrary value (which is referred to as a sensitivity adjustment value), the intensities of the reflected light at the angles of 20°, 70° and 5° of the light receiver are measured. Then, while maintaining the initial sensitivity adjustment value, the intensities of the reflected light at the angles of 20°, 70° and 5° of the light receiver at the time of incident of light to the same sample from an angle of −45° are measured. In the case of an incident angle of −60°, a relative intensity is similarly measured, and the light scattering rate is finally calculated.
When the light scattering rate represented by the above-mentioned formula (1) becomes 100%, the graph showing reflection intensity shown in the
The particles of the present invention has a reflected light intensity having higher uniformity despite of having a wrinkle-like or fold-like uneven structure on the surface thereof. The particles of the present invention are characterized in that the light scattering rate is in the range of 50 to 230%. At each observation of light incident angles of −30°, −45° and −60°, preferably the light scattering rate is in the range of 50 to 230% in either one of the incident angles, more preferably the light scattering rate is in the range of 50 to 230% in arbitrary two incident angles, and further preferably the light scattering rate is in the range of 50 to 230% in all of the incident angles. The light scattering rate of the particles of the present invention is preferably in the range of 50 to 200%, more preferably in the range of 70 to 190%, and further preferably in the range of 75 to 190%. This means that the particles of the present invention can enable more uniform omnidirectional reflection and, for example, when the particles of the present invention are used as an additive for cosmetics, it can be expected to develop a defocus effect.
In particular, in a measurement of distribution of the reflected light, it is preferable that a ratio of the maximum intensity of the reflected light in the vicinity of specular reflection (for example, within an angle of specular reflection ±10°, preferably within an angle of specular reflection ±5°) to the incident light, to the maximum intensity of the reflected light in the vicinity of the incident light (for example, within an angle of incident light ±10°, preferably within an angle of incident light ±5°) is in the range of 0.5:1 to 2:1, and preferably in the range of 0.5:1 to 1.8:1. When the intensity of specular reflection is in such a range, it can be expected to exhibit excellent optical characteristics, in particular, the defocus effect when the particles of the present invention are used as an additive for cosmetics (in particular, an additive for a foundation).
(Crystallization Degree)
In another aspect, the particles of the present invention are characterized in that a crystallization degree is 80% or less.

(wherein I22.6 and I18.5 indicate diffraction intensities at diffraction angles 2θ of 22.6° and 18.5°, and I22.6, blank and I18.5, blank each indicate diffraction intensities of only the glass capillaries at diffraction angles 2θ of 22.6° and 18.5°.)
Crystallization degree of cellulose type II crystal form (%)={(I20.0−I20.0, blank)−(I15.0−I15.0, blank)}/(I20.0−I20.0, blank)×100 (3)
(wherein I20.0 and I15.0 indicate diffraction intensities at diffraction angles 2θ of 20.0° and 15.0°, and I20.0, blank and I15.0, blank each indicate diffraction intensities of only the glass capillaries at diffraction angles 2θ of 20.0° and 15.0°.)
When the crystallization degree of the cellulose particles is high, strength is generally improved but flexibility is lowered, so that the crystallization degree is desirably suppressed appropriately. Accordingly, the crystallization degree of the particles of the present invention is 80% or less, preferably 75% or less, and more preferably 70% or less. On the other hand, the crystallization degree of the particles of the present invention is 20% or more, preferably 25% or more, and more preferably 30% or more.
