Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse.
It is a:
Humectant, drawing moisture into the skin
Emollient, helping to soften skin
Solvent, dispersing and stabilizing formulas
Preservative booster, enhancing the antimicrobial activity of other preservatives
Acrylates/C10-30 Alkyl Acrylate Crosspolymer is a synthetic polymer. It is used to thicken, emulsify, and improve the texture of products.
As an emulsifier, it helps stabilize oil-in-water emulsions to give products an elegant feel when applied.
It can also form a thin protective film on skin. One study found that a formula using this polymer helped slow down how quickly other ingredients (like DEET) were absorbed through skin.
A 2024 study of over 1,300 patients confirmed that sensitization to this ingredient is rare. It is also non-mutagenic and has a clean track record.
Behenyl Alcohol is a type of fatty alcohol (these are different from the drying, solvent alcohols).
Fatty Alcohols have hydrating properties and are most often used as an emollient or to thicken a product. They are usually derived from natural fats and oils; behenyl alcohol is derived from the fats of vegetable oils.
Emollients help keep your skin soft and hydrated by creating a film that traps moisture in.
In 2000, Behenyl Alcohol was approved by the US as medicine to reduce the duration of cold sores.
Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.
Caprylyl Methicone is a synthetic and lightweight silicone fluid. It gives products a silky, dry-touch finish without the heaviness of pure oils.
Though the EU CosIng Database lists this ingredient as a skin conditioner, it is also used for sensory reasons. It spreads easily, cuts greasiness, and reduces tackiness.
This ingredient is volatile which means it will mostly evaporate (but it evaporates slower than older cyclomethicones, like Cyclotetrasiloxane).
Typical concentration ranges from 1-30% depending on if it's being used to tweak the feel of a product or acting as the main emollient.
Dibutyl Adipate is a lightweight, oil-soluble ester that acts as an emollient and solvent. It helps products spread more easily and leaves a soft, silky, dry-touch finish without being greasy.
You'll likely see this ingredient in sunscreens because it does a nice job dissolving UV filters and keeping them evenly distributed.
This ingredient has been found to be safe as used in cosmetics, wasn't a skin or eye irritant in clinical patch testing, and wasn't phototoxic.
In a clinical comedogenicity test, this ingredient tested negative so it isn't likely to clog pores.
Typical use levels are about 5-8% for sunscreens + nail products, but can range from 0.005%-8% depending on the product.
Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB) is a chemical UV-A absorber. It is formulated for high UVA protection (320-400 nm).
DHHB is well-liked for:
DHHB has been approved by the EU, Japan, Taiwan, and South America for use up to 10%. Unfortunately, it has not been approved for use in the US or Canada due to slow regulatory processes.
This ingredient is soluble in oils, fats, and lipids.
Diethylhexyl Butamido Triazone (aka Iscotrizinol) is an oil-soluble organic UV filter that mainly absorbs UVB and a bit of UVA II light.
This ingredient is great at preventing sunburn but doesn't cover the deep UVA I range. This is why it's often paired with a UVA filter like Avobenzone or Bemotrizinol.
Two of its biggest selling points are efficiency and stability:
Most of the other chemical filters are considered "photostable" if they can last for two hours.
Because this ingredient is oil-loving, it can sit neatly into the oil phase of emulsions and shines in water-repellent/water-resistant formulations.
The EU and Canada allow it to be used up to 10% and Japan allows it up to 5%.
Unfortunately, it's not yet an FDA approved sunscreen agent so you won't be able to find it in sunscreens in the US.
Safety-wise, it has a pretty solid record: the EU's Scientific Committee on Consumer Safety (SCCS) has reviewed it and found low skin absorption, no capacity to produce skin irritation or photo-irritation.
In vitro testing has found less than 0.1% of the applied dose is absorbed by the skin over 24 hours (mostly due to its large molecule size).
Fun fact: This ingredient even has anti-inflammatory properties similar to those of ketoprofe, an anti-inflammatory medication.
Ethylhexyl Triazone (aka Octyl Triazone) is an oil-soluble organic UVB filter. It has peak absorption around 314 nm, right in the middle of the UVB range.
This ingredient is described as one of the most effective UVB filters available and small concentrations are enough to deliver a high SPF thanks to its strong UV absorbing power.
Formulators love it for its stability; its ability to filter UV stays practically unchanged even under intense radiation and it can also help boost the photostability of less stable filters like avobenzone.
It's also a great pick for water resistant products because it's insoluble in water and has a good affinity for keratin.
Because it's a big, heavy molecule, the European Scientific Committee has found to to have very low dermal penetration and negative results for allergenicity.
In vitro testing also showed a low absorption rate and clean results on irritation.
Typical use levels are 1-5% with 5% being the maximum in the EU, Japan, and other markets that allow it. However, this ingredient is not approved yet in the US or Canada.
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.
Polyacrylate Crosspolymer-6 is a texture enhancer and pH adjuster.
It is be used to thicken water-based products and create a gel-texture with a velvet feel.
One manufacturer claims this ingredient to have a pH range of 2-8 and to be biodegradable.
This ingredient is also known as Sepimax Zen.
Propanediol is an all-star ingredient. It softens, hydrates, and smooths the skin.
It’s often used to:
Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.
Tromethamine (aka THAM) is a synthetic amino acid that shows up in skincare as a helper ingredient.
It functions as a pH adjuster to help neutralize acidic ingredients and set a formula's pH to the right spot.
This matters a lot because a lot of actives (like vitamin C) needs a specific pH to work well and feel comfortable on skin.
Concentration use ranges from 0.1-1.0% depending on the formula.
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!
