Alcohol Denat.

What it does: Antimicrobial, Astringent, Masking, Solvent

Community Rating: Very Disliked

Alcohol Denat. is an alcohol with a denaturant property. It is created by mixing ethanol and other additives. It has a low molecular weight and will evaporate quickly. This helps other ingredients become better absorbed and dry once applied.

Alcohol Denat. is volatile and may cause irritation. It helps draw out natural oils in skin and dry out your skin.

One study from 2005 found adding emollients to propanol-based sanitizer decreased irritation.

Alcohol is antibacterial by nature. This can help preserve products and increase their shelf life.

Other types of astringent alcohols include:

Water

What it does: Skin Conditioning, Solvent

Community Rating: Loved

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. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

Methylpropanediol

What it does: Solvent

Community Rating: Mixed

Methylpropanediol is a synthetic solvent and humectant.

As a solvent, it helps dissolve other ingredients, helping to evenly distribute ingredients throughout the product. This ingredient has also been shown to have antimicrobial properties which makes it a preservative booster.

Methylpropanediol is able to add a bit of moisture to the skin. It also helps other ingredients be better absorbed into the skin, such as salicylic acid.

Glycolic Acid

What it does: Buffering

Community Rating: Loved

Glycolic Acid is arguably the most famous AHA with research to back up its benefits. Its main role is to peel the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and look more even.

Glycolic Acid has shown to boost collage production, a protein that helps skin stay firm. Overall, Glycolic Acid helps with improving uneven tone, rough patches of skin, fine lines, wrinkles, and sun damage. It also increases skin hydration by playing a role in creating molecules that create hyaluronic acid naturally.

When applying Glycolic Acid, it is normal to feel slight stinging. The pH value and concentration of glycolic acid play a role in the effectiveness of the product.

Recent studies have shown Glycolic Acid may protect the skin against UV damage. However, you should always wear SPF, especially when using exfoliants.

Diisopropyl Adipate

What it does: Emollient, Masking, Skin Conditioning, Solvent

Diisopropyl Adipate comes from isopropyl alcohol and Adipic Acid.

It is a solvent and emollient. As a solvent, it is used to help other ingredients dissolve into the solution. It is also often used to soften hard ingredients.

Emollients help hydrate the skin by creating a thin barrier. This thin barrier prevents moisture from escaping.

Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).

If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.

As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and look more even.

Sodium Hydroxide

What it does: Buffering

Community Rating: Mixed

Sodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective.

In small amounts, sodium hydroxide is considered safe to use. However, large amounts may cause chemical burns due to its high alkaline.

Your skin has a natural pH and acid mantle. This acid mantle helps prevent harmful bacteria from breaking through. The acid mantle also helps keep your skin hydrated.

"Alkaline" refers to a high pH level. A low pH level would be considered acidic.

Community Rating: Disliked
