A type of fatty alcohol. Fatty Alcohols are most often used as an emollient or to thicken a product. They are usually derived from natural fats and oils and therefore do not have the same drying or irritating effect as traditional alcohols.

Butylene Glycol Cocoate isn't fungal acne safe. It can be bad for dry skin.

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 

This ingredient is an emollient, solvent, and texture enhancer. It is considered a skin-softener by helping the skin prevent moisture loss.

It helps thicken a product's formula and makes it easier to spread by dissolving clumping compounds.

Hydroxyacetophenone is antioxidant with skin conditioning and soothing properties. It also boosts the efficiency of preservatives.

This ingredient is not irritating or sensitizing.

Tocopheryl Acetate is AKA Vitamin E. It is an antioxidant and protects your skin from free radicals. Free radicals damage the skin by breaking down collagen.

One study found using Tocopheryl Acetate with Vitamin C decreased the number of sunburned cells.

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.

Acrylates/C10-30 Alkyl Acrylate Crosspolymer is a synthetic polymer. It is used to thicken and improve the texture of products. Due to its properties, it can prevent water and oil ingredients from separating.

Tetrasodium Glutamate Diacetate is a chelating agent. Chelating agents help prevent metal ions from binding to other ingredients. This helps prevent unwanted effects and reactions from a product. These metal ions may come from water and are found in miniscule amounts.

Tetrasodium Glutamate Diacetate can also help other preservatives be more effective.

Bakuchiol is a plant-derived antioxidant (it's vegan!). It is often called the replacement for retinol although it is not part of the same family.

It has similar effects as retinol: skin smoothing, reducing discoloration, and preventing wrinkles. It does not cause as much irritation as traditional retinoids.

We don't have a description for Caramel yet.

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.

Tremella Fuciformis is also known as snow mushroom. This ingredient comes from the sporocarp, which is also the fruit body of the fungi.

Snow mushroom has hydrating and antioxidant properties.

Lactobacillus is a type of bacteria with skin conditioning properties. This ingredient has antibacterial and antifungal properties (that's why we can eat fermented foods).

Mannitol is a sugar alcohol. It is a humectant and moisturizes the skin. In vitro (not tested on a living organism), mannitol displays antioxidant properties.

When found in aqueous solutions, mannitol tends to become acidic. This is because it loses a hydrogen ion. This is why mannitol can often be found with pH adjusting ingredients, such as sodium bicarbonate.

Phosphatidylcholine is a type of phospholipid. Phospholipids are naturally found in our skin as they are the main component of cell membranes. Phospholipids are skin-replenishing.

This ingredient can be found in the Lecithin of soybeans.

Retinyl palmitate is a form of retinoid. Retinoids are the superstar class of anti-aging ingredients that include tretinoin and retinol.

This particular ingredient has had a bumpy year with its rise and fall in popularity.

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.
• It has mild preservative properties.

Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.

Cetyl Alcohol is a fatty alcohol. Fatty Alcohols are most often used as an emollient or to thicken a product.

Its main roles are:

Potassium Sorbate is a preservative used to prevent yeast and mold in products. It is commonly found in both cosmetic and food products.

This ingredient comes from potassium salt derived from sorbic acid. Sorbic acid is a natural antibiotic and effective against fungus.

Sodium Benzoate is a preservative. It's used in both cosmetic and food products to inhibit the growth of mold and bacteria. It is typically produced synthetically.

Both the US FDA and EU Health Committee have approved the use of sodium benzoate. In the US, levels of 0.1% (of the total product) are allowed.

Decyl Glucoside is a glucose-based surfactant and emulsion stabilizer. It is created by reacting glucose with the fatty acids from plants.

Surfactants help clean the skin by trapping oil, sebum, and dirt to be washed away. As an emulsion stabilizer, it stabilizes the ingredients in a product by preventing them from separating.

Lauryl Glucoside sugar- and lipid-based cleansing agent. It is created from glucose and lauryl alcohol.

Lauryl Glucoside makes it easier to rinse oil, dirt, and other polluants away.

CI 19140 is also known as Tartrazine. Tartrazine is a synthetic dye used in cosmetics, foods, and medicine to add a yellow color.

Tartrazine is created from petroleum and is water-soluble.

Lactobacillus Ferment is created by fermenting the Lactobacillus bacteria. It helps keep our skin's natural barrier and microbiome healthy.

Studies show lactobacillus ferment to be effective at repairing the skin barrier. Having a healthy skin barrier helps keep your skin healthy and hydrated. It also protects against bad bacteria.

Chances are, you eat sodium chloride every day. Sodium Chloride is also known as table salt.

This ingredient has many purposes in skincare: thickener, emulsifier, and exfoliator.
