Parfum is a catch-all term for an ingredient or more that is used to give a scent to products.

Also called "fragrance", this ingredient can be a blend of hundreds of chemicals or plant oils. This means every product with "fragrance" or "parfum" in the ingredients list is a different mixture.

Synthetic beeswax is created to be identical in structure to beeswax. It possesses the same occlusive and emulsion properties.

A blend of fatty acid esters, fatty acids, and alcohols are used to create synthetic beeswax. Whether or not this ingredient is vegan depends on the source. Sometimes, lanolin is used for its creation.

Silica Silylate is a siloxane polymer, meaning it is made up of silicon and oxygen atoms. It is not soluble in water.

This ingredient is a white powder with oil-absorbing, emollient, and anticaking properties.

Ethylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.

You might see Ethylhexylglycerin often paired with other preservatives such as phenoxyethanol. Ethylhexylglycerin has been found to increase the effectiveness of these other preservatives.

Ultramarines are a group of synthetic pigments. They can be either blue, green, pink, red, or violet.

Mineral sources are often used to create ultramarines. The FDA regulates this ingredient due to it potentially containing (trace) amounts of heavy metals.

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 

Trisodium Ethylenediamine Disuccinate is used to help stabilize a product.

It is a chelating agent, meaning it helps prevent metal ions from binding to other ingredients. This prevents unwanted reactions in products. Metal ions can come into a product via the water ingredient. They are found in trace amounts and are not known to be harmful.

Triethoxycaprylylsilane is a silicone used to bind and stabilize ingredients.

As an emulsifier, it helps prevent ingredients from separating. This can help elongate the shelf life of products.

Aluminum Hydroxide is a form of aluminum. It can be naturally found in nature as the mineral gibbsite. In cosmetics, Aluminum Hydroxide is used as a colorant, pH adjuster, and absorbent.

As a colorant, Aluminum Hydroxide may add opacity, or reduce the transparency. Aluminum hydroxide is contains both basic and acidic properties.

Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.

A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.

This ingredient is also known as Euphorbia Militaris Flower Extract, crown of thorns, or the Christ Plant.

Sodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.

Like hyaluronic acid, it is great at holding water and acts as a humectant. This makes it a great skin hydrating ingredient.
