Cosmeto-Textile Nanocapsule Treatment
topic
Cosmeto-textiles incorporate skin-active agents (retinol, vitamin E, aloe vera, caffeine, collagen peptides) in PMMA or chitosan nanocapsules (100–300 nm, 60–75% core content) applied to hosiery and intimate apparel at 10–25 g/m² via padding with polyurethane binder. Body heat (34–37°C skin surface) and friction during wear trigger capsule rupture, releasing active ingredients at 1–5 µg/cm²/h over 8–12 hours of wear. Clinical studies demonstrate 15–25% reduction in skin roughness (Ra measurement) and 10–20% improvement in skin hydration (Corneometer) after 4 weeks of daily wear. EU Cosmetics Regulation 1223/2009 governs claims and ingredient safety. Wash durability of 15–25 cycles limits service life. Premium cosmeto-textile hosiery retails at €30–80/pair versus €5–15 for conventional equivalents.
