It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product. So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation. You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated! This ingredient is also known as castor oil. It is a skin conditioning ingredient. The star component of castor oil is ricinoleic acid, an unusual fatty acid that makes up ~80-92% of its composition. In skincare, it is an emollient that dries down to a solid film with water-binding properties. This helps keep skin hydrated and helps reduce transepidermal water loss (TEWL). A 2026 dermatology review pulls together its broader uses: Human clinical testing found this ingredient to be non-irritating and non-sensitizing. Because castor oil contains fatty acids in the C11-24 range, this ingredient may not be fungal acne safe. At this time, the literature does not support castor oil in regrowing hair. A 2022 systematic review found no strong evidence that it supports hair growth and only weak evidence that it improves hair shine. Castor oil itself carries "perfuming" and "masking" function tags according to the official CosIng database. This is because of its mild odor and odor-dampening properties. We don't have a description for Acetamide Mea yet. Hydrolyzed Keratin is derived from keratin. Keratin is a large protein that is naturally found in our hair and skin. Studies show keratin is able to seal broken hair cuticles, helping to prevent split ends and breakage. As a humectant, hydrolyzed keratin helps draw moisture from the air to your hair and skin. This helps keep your skin and hair hydrated. Jojoba oil is one of the most well-studied plant-derived ingredients in cosmetics. It is an emollient with a special structure. Because it is made up of 97-98% wax esters, it closely mirrors the linear monoesters found in human sebum. This makes it skin compatible, non-greasy, and lightweight. Unlike other plant oils, jojoba wax doesn't easily penetrate skin. It mostly works in the uppermost layers as an emollient. This just means it forms a light barrier on the skin to help retain moisture. Formulations with jojoba esters up to 90% reduced transepidermal water loss (TEWL) and increased barrier recovery by 81% (outperforming bisabolol at 47%). Besides barrier support, the science also suggests jojoba to have anti-inflammatory effects and potential applications for skin infections, aging, and wound healing. Fun fact: Indigenous cultures have used jojoba as a moisturizer and to help treat burns for centuries. Fungal acne: The Malassezia yeast is known to metabolize fatty acids in the C11-24 range and jojoba's dominant fatty acid components fall into this range. This ingredient may not be fungal acne safe.
