Cat Eye Set 48 - I haven't used them yet, I am building up my collection of methacrylate free polishes. I love the colors though and can't wait to play with them. This set is confirmed by the company to be free of isobornyl methacrylate as well as HEMA, HPMA, and TPO.TLDR; Some of the Aimeili polishes are free of methacrylates, some are not. If you have allergies, make sure you only order polishes with free returns and check the ingredients as soon as you get them.I have allergic reactions to Sensationail, ibd, and Gelish polishes, so I’ve been looking for a polish that avoids all methacrylates and TPO. I am writing one review for all the polishes I’ve ordered from Aimeili in my quest for allergy free gel nails. My experience with the polishes:The quality of Aimeili polishes is great, easy to do thin coats but doesn’t flood the cuticles. Customer service answers questions about ingredients quickly. I was confused by the different labels on the actual bottles, thinking the black bar indicated allergen free, but there seems to be no correlation between label and ingredients.Not all of their polishes are methacrylate free. In fact ALL of their basecoats have isobornyl methacrylate. I’m very grateful that I can wear some of their polishes, though. Even though I can’t wear their basecoats I’m wearing 2 coats of a color polish (036) with their no-wipe top coat, without any allergic reaction. It starts chipping after 48 hours, of course, but I am looking into basecoats from Sundara Nails. I’m also going to try Orly Bonder as a base under Aimeili gels. Will update if those work. (UPDATE: Sundara has an excellent Gentle Rubber Basecoat that works well with the Aimeili gels - no allergies!)-------------------------------------------Aimeili methacrylate free polishes:Aimeili No Wipe TopcoatAimeili Matte TopcoatAIMEILI Soak Off UV LED Gel Nail Polish - Soft Pink (036) 10mlAIMEILI Sheer Nude Hema Free Gel Nail Polish Soak Off U V LED Neutral Skin Tone Gel Polish Colors for Nail Art Home DIY Gel Nail Manicure Kit Set Of 4pcs X 10ml - Kit Set 22AIMEILI Soak Off U V LED White Gel Nail Polish - Studio White Arctic White (011) 10mlAIMEILI Neon Gel Nail Polish Set Summer 12 Colors Gel Polish Hot Pink Orange Bright Nail Polish Gel Neon Yellow Green Purple LED Gel Nail Kit Nail Art DIY Manicure Gifts for Women DIY Salon Kit Set 24AIMEILI Gel Nail Polish Hema Free Glitter Gel Polish for Nail Art Gel Set Of 4pcs X 10ml - Kit Set 30AIMEILI Hema Free Solid Gel Nail Polish 12 Colours Sparkle Solid Nail Gel UV LED Soak Off Solid Cream Gel Polish Set 5-----------------------------------Aimeili polishes containing methacrylate:Aimeili Base CoatAIMEILI Hema Free Rubber Base Gel For Nails, Soak Off U V LED Clear Sheer Gel Nail Polish, 4 in 1 Nail Strengthen/Enhance/Base Coat/Color Gel Polish - (434) 10mlAIMEILI Clear Building Nail Gel Builder Base for Nail Repair Nails Extension Nail Strengthen, No Need Slip Solution Quick Extension Gel AIMEILI Nail Prep Bond Primer, U V LED Gel Foundation for Acrylic Powder and Builder Nail GelAIMEILI Fall Gel Nail Polish Red Glitter Emerald Green Black Golden Nail Polish Gel Gifts for Women, Set of 12pcs X 8ml - Kit Set 5AIMEILI Soak Off U V LED Fall Gel Nail Polish Set for Halloween Nail Art Gifts, Wine Brown Neutral Gel Nail Polish Set Of 12pcs X 8ml - Kit Set 4AIMEILI Reflective Gel Nail Polish Soak Off Reflective Glitter Gel Polish Holographic Diamond Glitter Nail Polish Kit Set of 12pcs X 8ml - Kit Set 7------------------------------------------------------The boxes of 6 piece sets list ingredients for both Color Coats and Builder Base. I emailed Aimeili and they confirmed that the Cat Eye polish (set 48) and Galaxy Paranoid polish (set 18) have the Color Coat ingredients and DO NOT contain isobornyl methacrylate. I’m going to guess that the same is true of set 21, and I’m keeping all 3.Sets that list both methacrylate free Color Coat ingredients and Builder Base ingredients with methacrylate:AIMEILI Gel Nail Polish Soak Off U V LED Gel Nail Lacquer, Black Wine Red Blue Glitter Color Gel Set Of 6pcs X 10ml - Kit Set 21AIMEILI Galaxy Paranoid Collection Soak Off Clear Glitter Gel Nail Polish Color for Christmas Gift Set Of 6pcs X 10ml - Kit Set 18AIMEILI Cat Eye Gel Nail Polish Soak Off U V LED Hema Free Nail Polish Nail Art Manicure Color Set Of 6pcs X 10ml - Kit Set 48Hope this helps!
