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!

This ingredient is considered an organic alcohol and commonly added into both cosmetics and foods.

Those with sensitive skin or conditions may deliver a rash when using this ingredient.

Peg-40 Hydrogenated Castor Oil is derived from castor oil and polyethylene glycol (PEG). It is used as a emollient and emulsifier.

As an emulsifier, it helps prevent ingredients from separating. It also helps make the other ingredients more soluble; it is often used to solubilize fragrances. This increases spreadability and elongates shelf life in a product.

Emollients help soothe and soften the skin. They do this by creating a protective film on your skin. This barrier helps trap moisture and keeps your skin hydrated. Emollients may be effective at treating dry or itchy skin.

This ingredient may or may not be vegan, depending on the source.

Peg-40 Hydrogenated Castor Oil may not be fungal-acne safe. We recommend speaking with a professional if you have any questions or concerns.

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

  • It is a solvent, meaning that it helps to dissolve other ingredients. This also enhances the absorption of the product into one's skin.
  • It is a humectant, which means that it helps attract moisture into the skin.
  • It helps improve product application.

Overall, Butylene Glycol is a safe and well-rounded ingredient. It is unlikely to irritate skin, and works well with pretty much all other ingredients.
