Beauty Kitchen Natruline Natural Lip TreatmentIngredients explained
Castor oil is sourced from the castor bean plant native to tropical areas in Eastern Africa and the Mediterranean Basin. It is an age-old ingredient (it’s over 4,000 years old!) with many uses including as a shoe polish, food additive and motor lubricant. You would be reasonable to think that putting shoe polish on your face wouldn’t be the best idea, but it turns out castor oil has some unique properties that make it a stalwart in thick and gloss-giving formulas (think lipsticks and highlighters).
So what is so special about it? The answer is its main fatty acid, called ricinoleic acid (85-95%). Unlike other fatty acids, ricinoleic acid has an extra water-loving part (aka -OH group) on its fatty chain that gives Castor Oil several unique properties. First, it is thicker than other oils, then its solubility is different (e.g. dissolves in alcohol but not in mineral oil), and it allows all kinds of chemical modifications other oils do not, hence the lots of Castor oil-derived ingredients. It is also more glossy than other oils, in fact, it creates the highest gloss of all natural oils when applied to the skin. Other than that, it is a very effective emollient and occlusive that reduces skin moisture loss so it is quite common in smaller amounts in moisturizers.
While it is very unlikely (and this is true for pretty much every ingredient), cases of reactions to castor oil have been reported, so if your skin is sensitive, it never hurts to patch test.
A chemically modified version of castor oil that results in a solid, waxy material that serves as an emollient and consistency building material.
It also has some unique moisturizing properties as it is both occlusive and humectant. The former one is common for oils and waxes and it means that it sits on top of the skin hindering water to evaporate out of the top layers. The latter one, the humectant property, is surprising and comes from the unique property of ricinoleic acid (the dominant fatty acid in castor oil) having an extra water-loving -OH group on its otherwise oil-loving fatty chain. We have some more info about this at castor oil, so if you are interested, read on here.
A vegetable wax coming from the leaves of the Brazilian tropical palm tree, Copernicia cerifera. Similar to other waxes, it is used to stabilize and give body to products, or to keep stick type formulas solid. It is the hardest natural wax with a high melting point (around 85C) and high gloss making it a great wax choice for lip products.
It's the yellow, solid stuff that you probably know from beeswax candles. It's a natural material produced by honey bees to build their honeycomb.
As for skincare, it's used as an emollient and thickening agent. It's super common in lip balms and lipsticks.
