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
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.
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.
Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.
Topically, glycerin does several things at once:
Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.
Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.
This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.
Just know very high concentrations (>40%) can feel tacky in low humidity.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.
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.
Polyglyceryl-3 Methylglucose Distearate is a plant-derived emulsifier whose only job is to keep the oily and watery parts of a formula blended so it doesn't separate into layers.
It's compatible with a wide-range of active ingredients and especially good at making emulsions survive heat/freeze cycles.
Typical use concentrations range from 2-3% and it works across a pH of 4.5-8.5.
This ingredient has been found safe to use in cosmetics and has a low irritation profile.
Because it's build on stearic acid, it may not be fungal acne safe. Stearic acid is a C18 fatty acid that falls within the range (C11-24) that Malassezia can feed on.
T-Butyl Alcohol (aka tert-butanol) is a small, clear, camphor-smelling alcohol.
It has two main jobs:
On the safety side, it's well-studied and has a solid track record. Human repeat-insult patch testing showed no skin irritation or sensitization even at 100%.
Typical use levels are pretty tiny, usually less than 1%.
You might see some fear-mongering around this ingredient:
Studies in male rats showed kidney effects but that's because of a rat-specific protein that humans don't make. So this study isn't really relevant to humans.
Though it's not a typical fragrance like parfum, it does have a natural scent. That's why the official COSIng database lists it as 'perfuming' ingredient. It can be used to modify the scent of a formula.
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!
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.
