ISONATURANE™ 12, OUR NATURALLY SOURCED ISODODECANE

Up until now, long lasting makeup required one key ingredient to be efficient. It was derived from petroleum: isododecane.Therefore, your waterproof mascara or long wear lipstick could not be truly “natural”…

Thanks to a patented biotechnology-based process, we were able to produce the very same ingredient from 100% natural renewable resources. We called it ISONATURANE™12. 

It is the first isododecane made from natural origin, and it is at the heart of every LAST product. Its efficiency is similar to the isododecane derived from petroleum.

For the first time, our LAST French makeup products can be up to 99.8% natural without compromising on their long wear efficiency. Our sustainable makeup range is nothing but environmentally conscious products with a long lasting finish.

WHAT IS ISODODÉCANE?


it is the key to long lasting and waterproof makeup.

It is the number one ingredient in proportion in products such as waterproof mascaras, no-transfer eyeshadows or long wear lipsticks.

It can represent up to 50% of these formulas in volume. Most often, it will be the first listed ingredient on these products.

HOW DOES IT WORK?


It makes color pigments soluble so they can better attach themselves to the skin – like a real mesh – and then nearly instantly evaporate.

As a result, colors are easily applied and dry to the touch on the skin, free from transfer in seconds only.

It does not dissolve in water, which enables us to achieve waterproof formulas.

It is the only molecule that provides these benefits to long lasting makeup.

HOW WAS IT MADE WITHOUT PETROLIUM?


Our team of scientists has successfully managed to convert plant resources (beetroot, corn, wheat, agricultural and forest waste) into isododecane thanks to biotechnology.

They selected and grew bacteria in an ideal environment and “taught” them how to convert plant-based sugar into isobutene through a unique fermentation process. Isobutene then leads to a 100% natural isododecane, fit for use in cosmetics.

We are particularly proud as it is the first time that this molecule is created without petrochemistry. It is a great leap ahead for sustainable makeup and to drive progress towards a better world.

WHAT ARE THE ENVIRONMENTAL BENEFITS OF ISONATURANE™ 12?


Our technology reduces the carbon footprint of our products.

Indeed, the method we use to get bio-sourced isododecane is a virtuous circle: the plants from which it is produced capture CO2. They are converted into isododecane that is incorporated into LAST products.

Once used, they lead to CO2 releases which the plants capture once again.

Over time, CO2 emissions will be reduced between 50 to 80%, compared to the use of petroleum, depending on the natural resources and the process used.

IS ISODODÉCANE GOOD FOR SKIN?


This cosmetic ingredient offers a health safety guarantee and therefore a sustainable French makeup.

Its safety has been known and well-documented for decades. In the exact same way, our natural-based and quality approved isododecane is a pure, stable and inert molecule.

About fifteen analyses have been conducted by specialized and independent professionals, all confirming the product’s high level of purity.
