Ingredients Explained
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!
Learn more about WaterThis ingredient is a low-molecular weight gas using as a propellant in foams, sprays, and mousses.
It is not intended to interact with skin in a meaningful way as it evaporates almost immediately after dispensing and only leaving behind the actual product formula.
If it does somehow make it onto your skin, it is chemically inert and does not penetrate or get absorbed into skin. Safety assessments note that adverse skin reactions to this ingredient are uncommon.
Learn more about IsobutaneVP/VA Copolymer is a synthetic polymer made by joining two smaller molecules (vinylpyrrolidone and vinyl acetate) into a larger chain.
It is mainly used as a film-former and fixing agent. When a product dries, it creates a thin and flexible layer on the skin, hair, or nails. This film helps hold hairstyles into place, adds a smooth feel to skin, and traps moisture to reduce dryness.
Irritation is rare at normal concentrations and it doesn't penetrate deeply into skin.

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.
Propane is a gas derived from petroleum and natural gas. In cosmetics, its only used as an aerosol propellant (it pushes your product out of the can when you press the nozzle).
That's why you'll find it in hair sprays, dry shampoos, deodorants, mousses, shaving foams, and sunscreen sprays.
It is volatile, meaning it only remains on skin for less than 10 seconds before evaporating. It doesn't really linger long enough on skin to act as a skincare ingredient in any meaningful way.
Hairspray concentrations are between 6-17%.
The CIR Expert Panel concluded it to be safe as a cosmetic ingredient under present concentration and usage.
Learn more about PropaneCocamidopropyl Betaine is a fatty acid created by mixing similar compounds in coconut oil and dimethylaminopropylamine, a compound with two amino groups.
This ingredient is a surfactant and cleanser. It helps gather the dirt, pollutants, and other impurities in your skin to be washed away. It also helps thicken a product and make the texture more creamy.
Being created from coconut oil means Cocamidopropyl Betaine is hydrating for the skin.
While Cocamidopropyl Betaine was believed to be an allergen, a study from 2012 disproved this. It found two compounds in unpure Cocamidopropyl Betaine to be the irritants: aminoamide and 3-dimethylaminopropylamine. High-grade and pure Cocamidopropyl Betaine did not induce allergic reactions during this study.

According to a manufacturer, this ingredient's stability is decreased by strong acid or alkali.
Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.
It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
Ethylhexylglycerin is created from glycerin. It is a multitasker ingredient that:
The CIR Expert Panel found minimal skin absorption or sensitization of any kind in a safety assessment. Though this ingredient is considered well-tolerated, a small number of cases of allergic dermatitis have been published since 2002. Just be sure to patch test if you are unsure.
Industry-reported use ranges from 8% in rinse-off products and 2% in leave-on formulations.
