Disclosed are polymers (polyaspartic acid derivatives) containing, in the molecule, 1 mol % or more of at least one repeating unit selected from the group consisting of repeating units represented by the following formulas (1) and (2).
These polymers are useful in the preparation of hair-treating compositions and cosmetic compositions having excellent hairdressing properties and good biocompatibility.
According to the present invention, there is provided cosmetics or external preparations for skin which comprises, as the effective ingredient, a chemical peeling agent, a bactericide, an anionic surfactant or a cationic surfactant component in combination with a compound capable of mitigating the irritation, inflammation, etc. of the skin caused by these components.
The present invention is skin cosmetics, external preparations for skin or hair cosmetics which are characterized by containing the following components (A) and (B) or it is skin cosmetics or external preparations for skin which are characterized by containing the following components (C) and (D)
Components (A) and (C): one or more members selected from a cystine derivative and salt thereof
Component (B): one or more of members selected from a chemical peeling agent, a bactericide and an anionic surfactant
Component (C): a cationic surfactant
There is provided a cosmetic composition, which stably includes disintegrable particles and is excellent in feeling upon use. A gel cosmetic composition, which has a pH of 4 to 9 and includes the following components (A), (B), (C), (D), and (E):
(A) disintegrable particles obtainable binding water-insoluble primary particles by use of a water-soluble binder;
(B) 15% to 70% by weight of polyol;
(C) a thickening polymer compound having a carboxy group;
(D) less than 1% by weight of water-soluble salts; and
(E) water.

A highly transparent water-soluble film is provided. The water-soluble film contains a PVA resin as a major component, and has not more than 50 dark defects each having a diameter of 1 to 5 mm per a 5 cm × 5 cm area thereof as observed under crossed Nicols after being uniaxially stretched under the following conditions (α):
(α) a test piece cut out of the water-soluble film to a size having a length of 25 cm and a width of 13 cm is clamped with chucks spaced 11 cm from each other longitudinally of the test piece in a stretching machine, and is uniaxially stretched at a stretching rate of 3 mm/second to a stretch ratio of 1.2 at a temperature of 23°C at a humidity of 50%RH.
The present invention relates to the provision of salt-sensitive particles capable of improving the feeling of effects at the time of use of an oil agent to be blended in a cleaner or the like and a method for producing the same, and so on.
The present invention provides the following [1] to [4].
[1] Salt-sensitive particles containing an oil agent having a solubility in 100 g of water of less than 1 g and an acid-modified polyvinyl alcohol, wherein the oil agent is dispersed in the salt-sensitive particles.
[2] A cleaner containing the salt-sensitive particles as set forth in [1].
[3] A method for cleaning a skin, a hair, or a clothing, including using the cleaner as set forth in [2].
[4] A method for producing the salt-sensitive particles as set forth in [1], including a step of preparing an emulsion composition containing an oil agent having a solubility in 100 g of water of less than 1 g and an acid-modified polyvinyl alcohol; and a step of removing the water from the emulsion composition.
