Ingredients higher up in an ingredient list are typically present in a larger amount. Sorbic Acid is a preservative that stops your product from spoiling by stopping microbes from growing. As a preservative, it's kind of a specialist: it has a broad spectrum of activity against yeast and molds but is weaker against bacteria. That's why it's often paired with another preservative to cover that gap. This ingredient is also pretty picky about pH; it performs best at pH 6.5 or below. At the right pH level, sorbic acid is "active" and can slip through the outer wall of a microbe. Once inside, it turns the cell's interior more acidic to shut down the microbe from the inside. The EU caps this ingredient at 0.6% while the CIR has concluded it's safe at concentrations up to 1%. It's most often used around 0.05-0.2% in cosmetics. Though this ingredient is considered low-sensitizing and well-tolerated, a very small number of people may have a contact allergy to it. Be sure to patch test if you have a history of allergies towards preservatives. 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 liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated! Xanthan gum is used as a stabilizer and thickener within cosmetic products. It helps give products a sticky, thick feeling - preventing them from being too runny. On the technical side of things, xanthan gum is a polysaccharide - a combination consisting of multiple sugar molecules bonded together. Xanthan gum is a pretty common and great ingredient. It is a natural, non-toxic, non-irritating ingredient that is also commonly used in food products.
