Ingredients higher up in an ingredient list are typically present in a larger amount. Acacia Senegal Gum has skin soothing, thickening, and formulation stabilizing properties. It comes from the Acacia tree that is native to sub-Saharan Africa. This is a synthetic polymer. It helps improve the texture of products by adding thickness and gel-like feel. It is also an emulsifer, meaning it prevents ingredients such as oil and water from separating. It also helps evenly disperse other ingredients. Polyhydroxystearic Acid is a vegetable-derived soft wax made from castor oil. It's an emulsion stabilizer, thickener, and film former. You'll likely see it in sunscreens because it helps disperse pigments and UV-reflecting minerals like titanium dioxide and zinc oxide evenly. Depending on the concentration, it can drastically change the texture of a product from pasty solid (like lipstick) to sprayable liquid. The CIR Expert Panel for Cosmetic Ingredient Safety has concluded this ingredient to be safe in cosmetics. The highest reported use concentration is 14.2% in lipsticks. Polysorbate 60 is used to help stabilize products. It is a surfactant and emulsifier. These properties help keep ingredients together in a product. Surfactants help reduce surface tension between ingredients with different states, such as liquids and solids. Emulsifiers help prevent oils and waters from separating. Polysorbate 60 is sorbitol-based and created from the ethoxylation of sorbitan. Ethoxylation is a chemical reaction used to add ethylene oxide. Sorbitan is a the dehydrated version of sorbitol, a sugar found in fruits. In this case, the 60 comes from reacting 60 units of ethylene oxide with sorbitan. Polysorbates are commonly used in medicine and foods. Sorbitan Isostearate is an emulsifer. It is created from isostearic acid and sorbitol. As an emulsifier, it keeps the water and oil ingredients from separating. This keeps formulas stable and smooth. In a 24 hour occlusive patch test on 56 subjects, 10% sorbitan isostearate was completely non-irritating. Most formulas use less than 10%. Because it's a fatty acid ester, it may not be fungal acne safe since the Malassezia yeast can utilize it as a nutrient source. Triethoxycaprylylsilane is a silicon-based surface modifier that makes sunscreens feel silky and makeup stay put. Its main job is to coat mineral particles like titanium dioxide, zinc oxide, and color pigments in a thin, oily layer so they spread smoothly, don't clump, and stick to skin better. This ingredient is typically used at low levels (up to 2.5% in eyeshadow and 1% in lipstick). Water. 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 liq
