A <strong>vernis \u00e0 ongles de marque en flacons carr\u00e9s<\/strong> (pensez aux lignes de luxe ou aux marques ind\u00e9pendantes d'architecture) attire l'attention.

Le ph\u00e9nom\u00e8ne BIAB : La viscosit\u00e9 d\u00e9termine le r\u00e9cipient<\/h2>\n\n\n\n<p>Le changement le plus significatif de l'\u00e8re 2024-2026 est l'explosion des <strong>vernis \u00e0 ongles \"builder in a bottle\" (constructeur dans une bouteille)<\/strong> (BIAB).<\/p>\n\n\n\n<p>BIAB est un hybride : plus \u00e9pais que le vernis en gel, mais plus doux que le gel dur. Il est con\u00e7u pour renforcer la structure des ongles naturels. En raison de ses propri\u00e9t\u00e9s thixotropiques uniques (il est \u00e9pais lorsqu'il est statique, mais coule lorsqu'il est bross\u00e9), il n\u00e9cessite une approche d'emballage sp\u00e9cialis\u00e9e.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">L'exigence d'un col large<\/h3>\n\n\n\n<p>Les bouteilles de polissage standard sont souvent dot\u00e9es d'un col 13\/415. Cependant, pour les <strong>vernis \u00e0 ongles \"builder in a bottle\" (constructeur dans une bouteille)<\/strong>, mais c'est insuffisant.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Le facteur \u201cessuyage\u201d :<\/strong> Le BIAB porte une lourde charge sur le pinceau. Si le col est trop \u00e9troit, l'utilisateur ne peut pas essuyer efficacement l'exc\u00e8s de produit sur la tige. Les filets sont alors inond\u00e9s de produit.<\/li>\n\n\n\n<li><strong>Le risque de gu\u00e9rison :<\/strong> Contrairement \u00e0 la laque qui s\u00e8che \u00e0 l'air, le BIAB durcit sous l'effet de la lumi\u00e8re UV. Si le r\u00e9sidu salissant sur les fils est expos\u00e9 \u00e0 la lumi\u00e8re du soleil, m\u00eame ambiante, pr\u00e8s d'une fen\u00eatre, il cr\u00e9e une liaison r\u00e9ticul\u00e9e permanente.
