purpurina

Purpurina, commonly known as glitter, refers to small, flat, reflective particles used to add sparkle to crafts, cosmetics, and performances. It is typically made from plastic films such as polyester or organza coated with aluminum or metallic pigments, giving a brilliant mirror-like finish. Particles come in various shapes (flakes, hexagons, circles) and sizes, often ranging from about 0.2 mm to several millimeters. In recent years, biodegradable glitter made from cellulose or polylactic acid (PLA) has been developed as an alternative aimed at reducing environmental impact. Even so, the term biodegradable is not universal and some products only degrade under industrial composting conditions.

Purpurina is used in arts and crafts, cosmetics, fashion and stage designs, and product packaging or decorative items. It is common in party supplies, scrapbooking, and nail art, among others. In cosmetics, it may be used in eye shadows, lip glosses, and body glitter, subject to safety and regulatory guidelines. Care should be taken to avoid contact with eyes and ingestion, particularly for children or in loose particle forms.

Environmental concerns: glitter can contribute to microplastic pollution in waterways and soils, especially when washed or discarded improperly. Biodegradable options using cellulose or PLA exist, but not all are fully compostable in home facilities. Proper disposal typically involves placing glitter-containing items in household trash rather than flushing or recycling due to material mix.
