Gelatin in stationary (Carbon-free copy paper), adhesives, etc

The special characteristics of gelatine as a protective colloid and the fact that its electrical charge is dependent on pH make it attractive as a wall material in microencapsulation. Gelatine and its derivatives can be used in the encapsulation of:

• Inks for carbon-free copy paper
• Chemicals for multi-component adhesives
• Vitamins for special applications

A further example for the application of special gelatines is the encapsulation of fragrances. A good example is the "scratch & sniff" perfume

advertising in the print media: microencapsulated fragrance oils are processed into printing varnish; when the surface is rubbed, the fragrance is released – all due to gelatine!

*gives paper its fragrance
