Ingredients higher up in an ingredient list are typically present in a larger amount. Butylene Glycol (or BG) is used within cosmetic products for a few different reasons: Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients. Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness. Caprylic/Capric Triglyceride (aka MCT Oil) is a lightweight emollient, solvent, and texture enhancer. It is considered a skin-softener by helping to prevent moisture loss. Though it behaves like an oil, it is not technically one due to its chemical composition. One perk of this ingredient is that it is very stable, resistant to oxidation, and unlikely to go rancid. In practice, that translates to a long shelf life and a consistently elegant skin feel. While there is an assumption Caprylic Triglyceride can clog pores due to it being derived from coconut oil, there is no research supporting this. Just patch test if you have concerns. Fractionated coconut oil and MCT Oil are both listed as Caprylic/Capric Triglyceride according to INCI. This is because INCI names are based on the ingredient’s final chemical composition and not its marketing name or source. This ingredient is treated as the gold standard fungal acne safe oil. Even though it is coconut derived, the problematic lauric acid is stripped out. This leaves just caprylic (C8) and capric (C10) acid. These chain lengths actually trend antifungal; a 2020 study found caprylic acid was enough to disrupt Malassezia furfur cell membrane, with a caprylic acid derivative damaging membrane structures at concentrations as low as 0.2%. Coco-Caprylate/Caprate is a lightweight ester created from coconut oil fatty acids, caprylic acid, and capric acid. It is an emollient that helps soften skin and reduce transepidermal water loss (TEWL). What sets it apart from heavier emollients is its ultralight, non-greasy feel. Once applied, this ingredient dries down quickly and leaves a dry, silky finish behind. This also helps improve spreadability and texture. This ingredient has an excellent safety-record and is non-irritating. Typical concentrations for cosmetics range from 0.5-62%. Research on Malassezia growth found no growth on fatty acid esters with chain lengths shorter than 12 carbons (it prefers C11-24). Since Coco-Caprylate/Caprate is built on C8 and C10 fatty acids, it is out of the range that Malassezia metabolizes, and therefore safe for fungal acne. Coconut Alkanes is a lightweight, plant-derived emollient and solvent made from the fatty acids of coconut oil. It spreads easily and adds a soft, silky, non-greasy slip, then evaporates rather than sinking into skin. Due to this behavior, it's prized as a natural and renewable replacement for silicones. Typical use concentrations can go anywhere up to 20%. The CIR Expert P
