The Science of Eyelash Extensions Adhesive
Adhesives - The science behind it.
Cyanoacrylate- This is the main ingredient in our adhesives. It is a colorless liquid that’s easily polymerized and used as a powerful, fast-acting adhesive. It is most commonly used in medical glues, like liquid bandages. This is what makes the adhesive stick. Cyanoacrylate is what gives us a wide range of viscosities, or textures (from thin to thick) and will determine what viscosity the adhesive will be. Cyanoacrylate undergoes a chain reaction called polymerization when exposed to moisture. This is what will cure the adhesive, and that’s exactly why you need some moisture or humidity in the air while you do lashes. If the area you are working in is too dry, the glue will not be able to dry or cure. This is also the reason your glue drop may dry faster or slower depending on the temperature and humidity of your work area.
Hydroquinone - This is a weak acid which prevents the adhesive from curing immediately. It is commonly found in many facial and skin care products. Hydroquinone finds the free radicals that will cure the adhesive and stops the polymerization or curing process. This helps control the reaction in the bottle and allows the adhesive to last longer, giving it a longer shelf life while still in your bottle, even after opening.This ingredient has unfortunately undergone a bad reputation due to it being used in whitening skin creams in high concentrations. Our adhesives only contain a very small amount (less than 1%) which results in much better stability, making it smooth in consistency and clump resistant.
PMMA aka Polymethyl methacrylate - This ingredient provides the elasticity or flexibility within the adhesive.
Carbon Black - Gives the deep black color. Carbon black is found in many food products as well and is not toxic. The purpose of carbon black is to add pigmentation.
Understanding your glue ingredients is so important... Not only will it take you from lash artist to lash alchemist, understanding how your glue ingredients work will help you maintain the best retention possible! Keep the dropper on your glue bottle clean of residue, and always put the cap back on tightly. Make sure that you follow the recommended humidity and temperatures for your glue, and always store your glue in a cool dark place, out of the sun. Don’t forget to shake that bottle vigorously for at least 30 seconds before using.
