    摘要: A water-resistant suntan gel comprising an alcoholic solvent, a sunscreen agent, emollients, a selected acid which enhances the binding ability of the gel film to the skin and a gelling agent for the solvent. The composition prevents sun damage to the skin and promotes an even tan. The composition forms a film on the skin, which film is water insoluble yet easily removable.

    摘要: A clear viscous and gelled antiperspirant solution comprising a gell solution of an alcoholic solvent and a gelling agent for the solvent, an antiperspirant dissolved in the gel solution, and a small but effective amount of emollient. The gelled antiperspirant can be applied easily. The antiperspirant is held effectively within the smooth film formed by the gelling agent. The gelling agent is a cellulose-based derivative modified with polyoxypropylene groups and substituted with acetyl groups.

    摘要: An overprint lacquer comprising a solvent, a resin, a plasticizer, and a gelling agent. The gelling agent is hydroxypropylcellulose acetate. The coatings of this gel-containing lacquer show improved adhesive characteristics and improved durability when compared with conventional overprint lacquers that have higher nitrocellulose content. Also, the viscosity of the lacquer is more readily controllable due to the presence of the gelling agent.
