Caprylyl Glycol is a humectant and emollient, meaning it attracts and preserves moisture.
It is a common ingredient in many products, especially those designed to hydrate skin. The primary benefits are retaining moisture, skin softening, and promoting a healthy skin barrier.
Though Caprylyl Glycol is an alcohol derived from fatty acids, it is not the kind that can dry out skin.
This ingredient is also used as a preservative to extend the life of products. It has slight antimicrobial properties.
Learn more about Caprylyl GlycolThis ingredient is a cleansing agent, surfactant, and foam booster. It considered an alternative to traditional sulfates (Sulfosuccinate) and is allowed in "sulfate-free" products.
According to a manufacturer, this ingredient is mild and can be used in baby and bath options.
We don't have a description for Laureth-21 yet.
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.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
Propylene Glycol is an odorless, colorless liquid. As a humectant, it helps skin retain moisture. It also aids in delivering active ingredients.
Another role of this ingredient is preventing a product from melting or freezing. Propylene glycol also adds antimicrobrial properties to a product, elongating product lifespan.
This ingredient is considered an organic alcohol and commonly added into both cosmetics and foods.
Those with sensitive skin or conditions may develop a rash when using this ingredient.
Learn more about Propylene GlycolThis ingredient is a preservative with antimicrobial properties. It is the sodium salt of dehydroacetic acid.
It is especially effective at preventing bacterial and fungal growth in low concentrations.
Sodium Lauryl Sulfate (SLS) is a sulfate with surfactant properties.
The surfactant property make it a great foam creator and cleansing agent. Surfactants help bind ingredients that normally do not mix.
Some studies have shown skin irritation due to prolonged SLS use.
Sodium Laureth Sulfate (SLES) is a milder version of SLS.

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. Stay hydrated!
