A method of producing a lip cosmetic, comprising the steps of: (i) mixing an oligomer (ingredient (a)) produced from behenic acid, eicosane diacid, and a glycerin condensate, a polyol (ingredient (b)), and water (ingredient (c)) to prepare a solution containing ingredients (a), (b), and (c); (ii) mixing an ester oil (ingredient (d)) composed of a carboxylic acid having 2 to 36 carbon atoms and an alcohol having 1 to 36 carbon atoms, being in a liquid or paste form at ordinary temperature, and having a viscosity of 300 mPa&#xb7;s or more at 25&#xb0; C. and an oligomer (ingredient (e)) produced from behenic acid, eicosane diacid, and glycerin to prepare a solution containing ingredients (d) and (e); and (iii) mixing the solution containing the ingredients (a), (b), and (c) and the solution containing the ingredients (d) and (e).

Methods of producing a lip cosmetic

The invention provides a gel-type water absorbent with rich flexibility and elasticity, with less variation in strength of gel during preservation, with low viscosity of sol, with easy processability, having a physical property with extremely less water discharge, and having functions of water absorbency and water solubility. The gel-type water absorbent contains a tamarind seed polysaccharide including 90% or more dietary fiber, 1% or less protein and 1% or less ash; and a water-soluble organic substance including at least one or more of a polyhydric alcohol and water-soluble surfactant.

Gel-type water absorbent

An esterification reaction product obtained by esterifying dipentaerythritol and a 12-hydroxystearic acid polymer and having a hydroxyl value of 20 to 70 mg KOH/g and an acid value of 3 mg KOH/g or less. The esterification reaction product has a high-water holding property and a pigment-dispersing property.
