Description

  The present invention relates to a cleansing composition that can be suitably used even on a wet face or hand.

  Cleansing compositions are cosmetics used for makeup removal and the like, and are roughly classified into aqueous cleansing agents and oil-based cleansing agents. Since the water-based cleansing agent does not contain oil or contains a trace amount, the oily feeling during use is small, but the cleansing power is poor. On the other hand, an oil-based cleansing agent does not contain water or contains a trace amount, and since it is excellent in cleansing power, it can be used suitably for makeup removal and the like.

  The oil-based cleansing agent is a reverse micelle oil solution mainly composed of an oil-based component and a surfactant, and the surfactant forms an aggregate in the oil with the hydrophilic portion inside. When a trace amount of water is blended with the oil-based cleansing agent, the water is solubilized in the vicinity of the hydrophilic portion and maintains a transparent state as a whole.

For example, JP-A-2004-238376, JP-A-2005-162691, and JP-A-2005-194249 mainly comprise a liquid oily component and a surfactant, and optionally contain a trace amount of water. Oily cleansing agents are described.
JP 2004-238376 A JP 2005-162691 A JP 2005-194249 A

  However, since oil-based cleansing agents usually have a small water solubilization amount, for example, when a relatively large amount of water is present, the solubilization limit is easily exceeded, and an emulsion is formed to form a two-phase solution. To do. When such two phases exist, the oil-based cleansing agent becomes white as a whole due to the difference in the refractive index of each phase. The cloudy state not only gives the user a visually unpleasant impression, but also causes a reduction in cleansing power and a feeling of use.

  In addition, some oil-based cleansing agents, when used on wet faces or hands, form higher-order molecular aggregates such as liquid crystals and thicken them, and also reduce the massage performance required for cleansing agents. There are things to do.

  The object of the present invention is to solve the above problems. That is, an object of the present invention is to provide an oil-based cleansing agent that is transparent and capable of exhibiting massage performance without forming a high-order molecular aggregate to increase viscosity.

The purpose of the present invention is based on the total weight of the composition
(A) 5 to 35% by weight of at least one ester oil having an organic value of less than 400 and an inorganic value of less than 100, or an organic value of 400 or more and an inorganic value of 100 or more,
(B) selected from mono- or polyesters of polyols and polyoxyalkylene glycol ethers having at least 3 carbon atoms and saturated or unsaturated fatty acids having from 8 to 24 carbon atoms, and from 76 to 86 At least one surfactant having a saponification number of 10-30% by weight, and (C) at least one diol 9-25% by weight
Is achieved by a cleansing composition comprising

  The amount of the ester oil (A) based on the total weight of the composition is preferably 10 to 25% by weight.

  The amount of the (C) diol based on the total weight of the composition is preferably 10 to 20% by mass.

  Furthermore, the cleansing composition of the present invention may contain 10 to 50% by weight of mineral oil based on the total weight of the composition.

  Furthermore, the cleansing composition of the present invention may contain 0.5 to 5% by weight of water relative to the total weight of the composition.

  The composition is applied to a keratin material such as skin or hair and used for cleansing the keratin material.

  The cleansing composition of the present invention is transparent, and even if a relatively large amount of water is present, it does not become cloudy or thickens by forming higher molecular aggregates, so that the massage performance does not deteriorate. Even a wet face or hand can be suitably used. Therefore, the cleansing composition of the present invention can be used even in a bathroom or shower room.

  Further, since the cleansing composition of the present invention forms an oil-in-water emulsion upon rinsing, it can be easily washed away with water, and it is unpleasant to the skin after use by removing excessive sebum. Does not leave a feeling of dryness.

  The cleansing composition of the present invention has a predetermined amount of (A) an organic value of less than 400 and an inorganic value of less than 100, or an organic value of 400 or more and an inorganic value of 100 or more.

  (A) The kind of at least one ester oil having an organic value of less than 400 and an inorganic value of less than 100, or an organic value of 400 or more and an inorganic value of 100 or more is not particularly limited, Any ester oil can be used as long as it has an organic value of less than 400 and an inorganic value of less than 100, or an organic value of 400 or more and an inorganic value of 100 or more. Here, the ester is a reaction product of a saturated or unsaturated fatty acid and an alcohol, and the fatty acid means a carboxylic acid having 4 or more carbon atoms. The fatty acid may be a mono fatty acid or a poly fatty acid. Similarly, the alcohol may be a monoalcohol or a polyalcohol.

Here, the “organic value” and the “inorganic value” are values specific to a compound that are generally used for preparing a graph known as an organic conceptual diagram. The organic concept diagram was proposed by Dr. Satoshi Fujita, and its details are described in "Pharmaceutical Bulletin", vol.2, 2, pp.163-173 (1954), "Chemical domain" vol.11, 10 , pp.719-725 (1957), “Fragrance Journal”, vol.50, pp.79-82 (1981), etc. That is, methane (CH ₄ ) is used as the root of all organic compounds, and all other compounds are regarded as derivatives of methane, and certain numbers are set for the number of carbon atoms, substituents, transformation parts, rings, etc. The score is added to obtain an organic value and an inorganic value, and these values are plotted on a diagram with the organic value on the X axis and the inorganic value on the Y axis. This organic conceptual diagram is also shown in “Organic Conceptual Diagram-Basics and Applications” (by Yoshio Koda, Sankyo Publishing, 1984).

“Organic values” and “inorganic values” are also described, for example, in the following documents:

In more detail, in order to calculate the organic value of a compound, a methylene group is considered as a unit and is evaluated by the number of carbon atoms. A carbon atom or a —CH ₃ , —CH ₂ — or ═CH— group is calculated as a value of 20. Hydrogen atoms are not considered. The presence of rings, branches, or ethylenic or acetylenic unsaturation in the organic compounds is known in the literature, in particular “Pharmaceutical Bulletin”, vol. 2, 2, pp. 163-173 (1954), p. 167. Is taken into account when calculating the organic value of the compound according to the corresponding organic value.

  In order to calculate the inorganic value of a compound, the hydroxyl group is considered as a standard group, to which a value of 100 is given. This value of 100 correlates with the distance between the boiling point curve for the alkane series as a function of the number of carbon atoms in the alkane and the boiling point curve for the linear saturated primary monoalcohol analog for the alkane.

The inorganic value of the substituent X (expressed as Ix) is determined by the graph. This value Ix is primarily determined by measuring the boiling point (bp) of the linear alkane and the boiling point (bpx) of the analog of the linear alkane substituted with the substituent X, and then the difference ΔTx = bpx− It is calculated by calculating bp and secondly measuring the boiling point (bpOH) of the analogue substituted with the primary alcohol group and then calculating the difference ΔT _OH = bpOH-bp. Value Ix is equal to the ratio of the difference ΔTx for the difference [Delta] T _OH, the ratio are all multiplied by the inorganic value equal to 100 hydroxyl groups.

  The inorganic values of many substituents are described in various documents, especially in the above documents. The inorganic value of a compound is calculated by adding the inorganic value of the substituent present in the compound. For example, certain substituents, such as the substituents -Cl or -F, can be defined as organic values as shown on page 167 of "Pharmaceutical Bulletin", vol. 2, 2, pp. 163-173 (1954). It has both inorganic values.
