Do not use with: There aren’t any components recognized to work together poorly with isoparaffin.

What’s Isoparaffin?

“Isoparaffin is a branched-chain of saturated hydrocarbons derived from petroleum,” explains Petrillo. Or, merely put, it is a sort of petroleum-derived mineral oil. In skincare and cosmetics, isoparaffin is usually present in moisturizers, sunscreen, lip merchandise, foundations, cleansers, deodorants, make-up removers—just about all over the place, provides Frieling. This isn’t solely as a result of it is used as an emollient to assist pores and skin appear and feel clean but in addition for formulation causes; isoparaffin is a texture enhancer that may assist create thick, creamy formulation that will not really feel greasy on the pores and skin, notes Frieling. And, as a result of it is made up of simply hydrogen and carbon atoms, it is not very reactive; it performs properly with most different components, one other attribute that accounts for its reputation and prevalence within the skincare world.

Advantages of Isoparaffin for Pores and skin

The advantages of isoparaffin all come all the way down to its emollient and semi-occlusive properties. “As an emollient ingredient, isoparaffin helps to restore the pores and skin barrier by filling in areas between the corneocytes, or useless pores and skin cells, that are held collectively by a lipid matrix,” says Petrillo. Consider these cells as bricks and that lipid matrix as mortar; isoparaffin and different emollients assist to fill in cracks in that mortar to maintain the pores and skin barrier sturdy and intact. And a powerful pores and skin barrier is important for preserving potential irritants from entering into the pores and skin and pure moisture from escaping.

Equally, isoparaffin is not that totally different from different components that assist forestall moisture loss, akin to petroleum and lanolin, says Howe. All of those molecules are too massive to penetrate deep into the pores and skin and as an alternative sit on prime of the stratum corneum, the uppermost layer of the pores and skin, the place they create an occlusive movie or seal that locks in moisture. The distinction? “Isoparaffin does not include the identical sort of ‘smothering sensation’ as you get with different, heavier occlusive components,” says Howe. (Therefore why it is so usually added into wealthy and heavy lotions and lotions, the place it retains them from feeling greasy or cheesy.)

Facet Results of Isoparaffin

“Whereas it’s thought-about a non-irritating ingredient, some pores and skin allergy symptoms have been linked to isoparaffin,” cautions Frieling, who provides that these with delicate pores and skin might wish to take a go. (When doubtful, patch testing any new product or ingredient in your interior forearm for just a few days is all the time good earlier than placing it in your face.)

In response to Frieling, isoparaffin by itself is a non-comedogenic ingredient, but it surely’s nonetheless a good suggestion to keep away from it when you have oily or acne-prone pores and skin. As is the case with different related, occlusive components, it does not break down simply, and there is a danger of it trapping oil and micro organism within the pores and skin, says Petrillo.

Then there’s the large, elephant-in-the-room security query. All the consultants we spoke with agree that isoparaffin is taken into account a protected ingredient. The Environmental Working Group ranks it at one out of 10 on their security scale (with 10 being probably the most probably harmful or dangerous). Petrillo notes that the Beauty Ingredient Overview (CIR) has concluded it is protected to be used in cosmetics, whereas Howe factors out that the FDA even permits it for use immediately in some meals, for instance, as a coating on fruit. That being stated, the security questions come into play as a result of this can be a petroleum-derived ingredient. As such, there is a potential danger of contamination from a carcinogenic (learn: cancer-causing) substance generally known as 1,4-dioxane. This comes with the danger of pores and skin allergy symptoms in and of its personal proper, but it surely’s additionally a neurotoxin, respiratory toxin, and kidney toxin, says Frieling. That is admittedly pretty regarding and is why you are unlikely to see isoparaffin in so-called “clear” magnificence merchandise.

Methods to Use It

On the finish of the day, take into account that isoparaffin is extraordinarily widespread; most skincare merchandise include, on the very least, a small quantity, says Frieling. And sure, when you have delicate or acne-prone pores and skin (or try to stay with squeaky-clean merchandise), you might wish to take the time to learn ingredient labels and keep away from it as a lot as doable. On the flip facet, when you have additional dry, flaky pores and skin, you may probably profit from its emollient properties greater than anybody else. However broadly talking, most of us can take into account this an ingredient that falls extra into the impartial class than the rest. “It is neither an ingredient it’s worthwhile to hunt down neither is one which it’s worthwhile to keep away from,” says Howe.
