Description

  The present invention relates to a cosmetic composition, and more particularly to a cosmetic composition used for a cosmetic having a cream, gel, emulsion or liquid dosage form.

Conventionally, cosmetic compositions generally referred to as creams or emulsions are known.
Such cosmetic compositions, which contain oil as an essential component, are manufactured in a variety of forms, from anhydrous oily creams to water-containing products that are mixed or emulsified with water, but these are blended and adjusted to have a uniform viscosity. The creamy or milky viscosity is used to spread thinly on the skin to exert various skin beautifying effects.
Specifically, in such a cosmetic composition, glycerin, propylene glycol, higher fatty acid, higher alcohol, etc. that are compatible with water, and beeswax, lanolin, which are incompatible with water, in order to exhibit viscosity. Emulsification of vegetable oils, fatty acids, higher alcohols, hydrocarbons, squalane, etc. with water is the basis of the formulation, and by using a lot of oil in this way, oil and moisture are replenished to the skin to crack and dry. In some cases, the skin effect is exhibited by the medicinal effects of appropriately formulated medicinal ingredients.
However, if a lot of oil is used to make it viscous and creamy or milky, it becomes sticky and the feeling of use deteriorates.

Therefore, for the purpose of imparting a shape retention ability (shape retention) to maintain thickening and dispersion stability, for example, water-soluble cellulose derivatives such as methylcellulose and carboxymethylcellulose salts, polyvinyl alcohol, polyvinylpyrrolidone, carboxyvinyl It is known to use polymers, synthetic polymers such as polyethylene glycol, natural polymer polysaccharides such as quince seed, bee gum, xanthan gum, and hyaluronate.
However, since many of these polymer materials are water-soluble, they often have stringiness and are uncomfortable to use, and many have poor salt resistance.

From such a background, there is a demand for a cosmetic composition having a good feeling of use that does not have a sticky feeling derived from an oily component or a water-soluble polymer and has a good stretch.
On the other hand, for example, without regenerating natural cellulose, the cumulative volume ratio of particles having an integrated volume of 50% obtained by hydrolysis and physical pulverization is 0.3 to 6 μm and 3 μm or less. There has been proposed a cosmetic composition that eliminates the feeling of stickiness by using a micronized cellulose material having a weight of 25% or more (Patent Document 1).
However, this cosmetic composition has a lower oily component ratio than conventional cosmetic compositions and can achieve creamy or milky properties, but includes cellulose materials having a large particle size. Therefore, the dispersibility is insufficient and there is a feeling of roughness.

  Therefore, in order to solve such problems, cosmetic compositions using cellulose finely divided into nanosizes have been proposed (Patent Documents 2 and 3).

JP-A-5-32519 JP 2000-26229 A JP 2017-48181 A

However, those described in Patent Documents 2 and 3 have a problem in environmental load and workability because a large amount of sulfuric acid is required for producing cellulose fine particles.
Moreover, since the thing of patent document 2 has the low salt tolerance of the dispersion of a cellulose fine particle, there exists a subject that an application range is restrict | limited greatly, and the thing of patent document 3 suppresses aggregation of a fine cellulose. Therefore, it was necessary to use a water-soluble polymer with stickiness.
As described above, there is still room for improvement in order to realize a cosmetic composition having a good feeling of use that does not have a sticky feeling after application and has a good elongation at the time of application.

  An object of the present invention is to provide a cosmetic composition having a good feeling of use that has no stickiness after application and has a good elongation during application.

In order to solve the above problems, the invention according to claim 1 is a cosmetic composition,
It contains the following components (A), (B) and (C).
(A) Oily component (B) Wood-derived cellulose nanofiber (C) water having an average fiber width of 10 to 100 nm According to the invention according to claim 1, there is no stickiness after coating, and at the time of coating. A cosmetic composition having a good elongation and a good feeling of use can be realized.

The invention described in claim 2 is the cosmetic composition according to claim 1,
The oil component includes one or more hydrocarbons selected from squalane, paraffin, polyethylene wax, microcrystalline wax, liquid paraffin, and mineral oil.
According to the second aspect of the present invention, the same effect as in the first aspect can be obtained. In particular, a cosmetic composition containing a hydrocarbon among oily components often develops a sticky feeling. However, according to the invention described in claim 2, even in this case, the sticky feeling after application is still present. It is possible to realize a cosmetic composition that is free and has a good feeling during use and has a good elongation during application.

  According to the present invention, it is possible to realize a cosmetic composition that has no feeling of stickiness after application and has a good feeling of use and has a good elongation during application.

Cellulose nanofibers (hereinafter referred to as “CNF”) are, for example, wood-derived CNF having an average fiber width (median diameter) of 10 to 100 nm manufactured without chemical modification from softwood pulp. Various kraft pulp and mechanical pulp derived from wood are used. NBKP (conifer bleached kraft pulp) and LBKP (hardwood bleached kraft pulp) are preferably produced as raw materials, but those produced using other pulps as raw materials may be used. Also, kraft pulp such as hardwood kraft pulp (LUKP) and softwood kraft pulp (NUKP), in which ozone treatment with strong oxidizing power effectively functions against lignin that cannot be removed even after delignification treatment, especially In the case of including an enzyme treatment step, hardwood kraft pulp (LUKP) can also be used from the viewpoint of processability in the subsequent step.
As described above, the average fiber width (median diameter) of CNF is preferably 10 to 100 nm, more preferably 10 to 60 nm. When the average fiber width exceeds 100 nm, it is difficult to obtain the effect, and there is no knowledge that those having an average fiber width of less than 10 nm were produced without chemical modification.

  CNF can be obtained without chemical modification by a known method such as refinement treatment of NBKP and rough fibrillation followed by treatment with a high-pressure homogenizer. In addition, you may perform an enzyme process, a chemical process, etc. in the middle process.

Here, a method for measuring the average fiber width of CNF will be described.
First, 100 ml of an aqueous dispersion of cellulose nanofibers having a solid content concentration of 0.01 to 0.1% by mass was filtered with a Teflon (registered trademark) membrane filter, and once with 100 ml of ethanol and three times with 20 ml of t-butanol. Replace.
Next, the sample is freeze-dried and coated with osmium. This sample is observed by an electron microscope SEM image at a magnification of 5000 times, 10000 times, or 30000 times (in this example, a magnification of 30000 times) depending on the width of the constituent fibers. Specifically, two diagonal lines are drawn on the observation image, and three straight lines passing through the intersections of the diagonal lines are arbitrarily drawn. Further, the total width of 100 fibers intersecting with the three straight lines is visually measured. And the median diameter (median diameter) of a measured value is made into an average fiber width. In addition, it is good also considering not only the median diameter of a measured value but a number average diameter and a mode diameter (mode diameter) as an average fiber width, for example.

  Moreover, although the compounding quantity of CNF contained in the cosmetic composition of this invention is adjusted with the function calculated | required, normally the compounding quantity of CNF is 0.05 weight%-10.0 weight as CNF water dispersion slurry. % Is preferable, and more preferably in the range of 0.2% by weight to 5.0% by weight. When the blending amount of CNF is within this range, a cosmetic composition having excellent usability can be realized.
