Cosmetics containing the following components (A) and (B): (A) an oil-absorbing powder having a squalane-absorbing ability of 1 ml/g or more; and (B) a compound having an affinity for component (A) lower than that of sebum, and having an ability to absorb the sebum and release component (B) in exchange for the sebum when the cosmetic is applied onto the skin. These cosmetics can adequately absorb the sebum and thus exhibit excellent effects of relieving or preventing oiliness of the skin and worsening in makeup. By selecting an appropriate compound to be released in exchange for the absorbed sebum, a substance capable of improving the skin qualities such as moistness, tightness, and tension can be allowed to penetrate into the skin. Moreover, a bodily feeling of the removal of the sebum can be imparted to users thereby.

The present invention relates to a phosphorylated glyceryl ether aluminum salt represented by the general formula (1): (wherein Rrepresents an alkyl or an alkenyl group with 8 to 32 carbon atoms; Rrepresents a hydrogen atom, a phosphoric acid residue or &#x2014;CHCH(OR)CHOR(wherein Rand Rare the same as described above, provided that a repeated binding number is 4 at the most when Ris &#x2014;CHCH(OR)CHOR); Xrepresents a hydrogen atom or a phosphoric acid residue, and at least one of Xand Ris a phosphoric acid residue; Y represents an alkali metal atom or an alkaline earth metal atom; m represents a number from 0.3 to 1, and n represents a number from 0 to 1), and an external dermatological agent containing the same. The compound has benefits such as an excellent pore contracting activity and also a good solubility in oil.

Phosphorylated glyceryl ether aluminum salt

Sheet cosmetics including a single-layered aqueous gel sheet having no supporting layer wherein the sheet of 1 mm in thickness has a light transmittance of 70% or more. These sheet cosmetics have high adhesion force to the skin, transparent appearance presenting no sense of incongruity and achieve excellent moistening and cooling effects on the skin.

Sheet cosmetics
