Cocamidopropyl Betaine is a fatty acid created by mixing similar compounds in coconut oil and dimethylaminopropylamine, a compound with two amino groups.

This ingredient is a surfactant and cleanser. It helps gather the dirt, pollutants, and other impurities in your skin to be washed away. It also helps thicken a product and make the texture more creamy.

Cyclotetrasiloxane is a type of silicone.

Dimethicone is a type of synthetic silicone created from natural materials such as quartz.

What it does:

Dimethiconol is a silicone that resembles the popular dimethicone. Like other silicones, it is an emollient. Emollients create a thin film on skin to prevent moisture from escaping.

This ingredient helps to create a silky texture and improve spreadability. Due to its high molecular weight and thickness, it is often combined with cyclopentasiloxane.

DMDM Hydantoin has antimicrobial and antifungal properties. It is a preservative that works by slowly releasing formaldehyde over time.

So what's formaldehyde?

This ingredient is derived from guar gum.

It is a conditioning ingredient, meaning it helps soften skin and hair.

Iodopropynyl Butylcarbamate is a preservative.

Laureth-23 is created by reacting ethylene oxide with Lauryl Alcohol.

It is a cleansing ingredient. This means it helps lift oils and dirt so they may be rinsed away with water.

Laureth-4 is created by reacting ethylene oxide with Lauryl Alcohol. It is a surfactant and emulsifier.

Surfactants reduce the surface tension of ingredients so they can mix better. Emulsifiers prevent ingredients such as oil and water from separating.

MI is a preservative and known skin irritant. In the past, MI was used for its ability to prevent bacteria, yeast, and fungi growth in low doses.

Nowadays, you'll most likely see MI combined with Methylchloroisothiazolinone (MCI). Trade names for this combination include Kathon CG or Euxyl K 100.

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.

Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.

We don't have a description for Poloxamer 407 yet.

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.

We don't have a description for PPG-9 yet.

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.

Sodium Laureth Sulfate (SLES) is a foaming, cleansing, and emulsifying ingredient. It is created from palm kernel oil or coconut oil. SLES is not the same as sodium lauryl sulfate. It is much milder and less likely to irritate.

SLES helps create foam in personal products. It also prevents ingredients from separating, helping to elongate the shelf life.

We don't have a description for Sodium Polynaphthalenesulfonate yet.

We don't have a description for Tea-Dodecylbenzenesulfonate yet.

Tea-Sulfate is a type of sulfate.

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.

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.

Zinc Pyrithione is a preservative. It inhibits the multiplying of fungal and bacterial cells.

You'll most likely find this ingredient in Malassezia treatments. In the US, this ingredient is most common in anti-dandruff shampoos. However, the European Union has prohibited the use of this ingredient starting in 2022.

Zinc Sulfate has antimicrobial and astringent properties. It is created synthetically from zinc and sulfuric acid.

Despite having ‘sulfate’ in the name, it isn’t a surfactant or cleansing agent like sodium lauryl sulfate. Unlike those sulfates, zinc sulfate doesn’t have the same cleansing or foaming properties.
