Ingredients higher up in an ingredient list are typically present in a larger amount. Alpha-Isomethyl Ionone is a fragrance. It can be synthetically created or naturally occurring. The scent of Alpha-Isomethyl Ionone is described as "flowery" but can also be "woody". Naturally occurring Alpha-Isomethyl Ionone may be found in Saccharomyces cerevisiae, or the yeast used to make wine and bread. The term 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term. For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance. This water-soluble silicone is used for its hydrating and softening properties. It is used to add a silky feel to skincare products and has great benefits for haircare. In haircare, this ingredient: Adds shine Protects color Offers thermal protection Boosts hair strength Does not build up as easily This ingredient is a preservative and often used for it's anti-static properties. You'll most likely see this ingredient in hair conditioners. It does not cause irritation or sensitization in leave-on products at 1-5%. Carbomer is a synthetic thickening and gelling agent. It's basically the ingredient that gives a lot of serums, gels, creams, and sunscreens their smooth, non-sticky texture. Although legally permitted at very high levels, carbomers are normally used at concentrations below 1%. It also needs to be neutralized to actually thicken, and because it is a large molecule, it doesn't really penetrate the skin barrier. Allergy-wise, the risk is very low. Clinical studies show carbomers have low potential for skin irritation/sensitization even at concentrations up to 100%. A 2024 UK study patch-tested 1,302 patients and found true allergy to the parent group of carbomer to be rare with no confirmed relevant reactions. This ingredient is a preservative, antimicrobial, and emulsifier. It is often used in cosmetics for its ability to cleanse, condition, and reduce static. Cetrimonium chloride is a quaternary ammonium salt, meaning it has a water-soluble structure. Citric Acid is an alpha hydroxy acid (AHA) naturally found in citrus fruits like oranges, lemons, and limes. Like other AHAs, citric acid can exfoliate skin by breaking down the bonds that hold dead skin cells together. This helps reveal smoother and brighter skin underneath. However, this exfoliating effect only happens at high concentrations (20%) which can be hard to find in cosmetic products. Due to this, citric acid is usually included in small amounts as a pH adjuster. This helps keep products slightly more acidic and compatible with skin's natural pH. In skincare formulas, citric acid can: While it can provide some skin benefits, research shows lactic acid and glycolic acid are generally more effective and less
