The world of manicure has evolved radically, moving from a search for perfection and mirror shine at all costs to a more eco-friendly and nail-friendly approach. Long-described for its problematic ingredients and the risks it posed to nail health, the traditional semi-permanent varnish is now competed with organic varnish formulas. But what exactly is organic varnish? What do these new generation varnishes contain? And how can I recognize a good organic varnish? We answer all your questions to help you find the best options for a durable and efficient manicure.
What is a semi-permanent organic varnish?
Definition
The term "in the first place" is organic varnish does not mean that the varnish is 100% natural or contains natural ingredients from organic farming. Let's say that bio-based varnish. When you talk about semi-permanent organic varnish, therefore, a long-lasting varnish, where a majority of ingredients are derived from plant biomass.
Unlike traditional semi-permanent varnish manufacturers who supply solvents, plasticizers and other components to the petrochemical industry, organic varnish brands are seeking to vegetable alternatives. The objective is twofold:
Use Renewable resources and reduce the carbon footprint of the product.
Propose healthier and more nail-friendly formulas without degrade the performance of semi-permanent varnish.

With semi-permanent natural varnishes, opt for an eco-responsible and non-toxic varnish formula.
What distinguishes it from a semi-permanent traditional varnish
As we have just mentioned, the major difference lies in the chemical composition. Where a traditional semi-permanent varnish contains solvents, plasticisers and synthetic resins that may present risks of irritation or allergy in contact with the skin, bio-based gel varnish favours the use of a plant alternatives without health risk.
The following are examples of natural alternative ingredients and bio-sourced solvents that make up the formula of the semi-permanent varnish Green Flash™ of the Manucurist :
• Nitrocellulosis, key ingredient that guarantees strength and shine is derived from the cotton.
• Ethyl acetate, solvent that ensures the fluid application of the varnish, is produced from the sugar cane.
• Another solvent, theButyl acetate is extracted from cassava.
• Acetyltributylcitrate, a plasticizing agent that ensures the flexibility of the varnish, comes from the maize.
• Stearalkonium bentonite which stabilizes the viscosity of the varnish is derived from theclay.

Sugar cane, cotton, corn... our vegetable alternatives to oil-derived solvents and plasticizers.
Another advantage that distinguishes these natural varnish formulas: their composition allows for a ultra-soft and express withdrawal - I'm not. With a classic semi-permanent, the removal is done by sanding or applying acetone for 10 to 15 minutes, which can leave the nail in a sad state. With Green Flash™, the varnish withdraws with a soft solvent, made of peel-off 1-2 minutes per hand, without sanding or acetone, and especially without damage to the nail. A real revolution!
Substances to be avoided absolutely
Reading theINCI label (the one that specifies the composition of the varnish on the back of the bottle) must be your first reflex when you buy a nail polish, especially if it is manufactured outside the European Union. Whatever the varnish marks, check that they do not contain substances at risk such as:
• Methylacrylate monomers (HEMA, DI-HEMA TMHDC) : highly used in the first formulae of semi-permanents for their ability to form a very solid film on the nail, these molecules have proved highly sensitizing. Since 2021, the EU has banned them in the manufacture and sale of cosmetic products.
• Substances classified as CMR (carcinogens, mutagens, reprotoxics): this category includes: endocrine disruptors As a result, the Commission has not yet taken into account the fact that the Union industry is not in a position to meet its obligations under the Treaty. TPO, toluene, dibutyl phthalate (or DBP), formaldehyde, hydroquinone, xylene, ethyl tosylamide, benzophenone, styrene, phenoxyethanol.
• The camphor is also a toxic component as it can cause serious side effects in the event of overexposure or ingestion.

With this commitment, Green Flash™ has always been ahead of the development of European cosmetics regulations and Manucurist is a pioneering brand of responsible and sustainable beauty.
