Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Skin Conditioning, Solvent

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. If you see this, drink a glass of water. Stay hydrated!

Cleansing, Foaming

This 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.

Cleansing, Foaming

Sodium Lauryl Sulfoacetate is an organic salt with a naturally sweet odor. It is an alternative to traditional sulfates and is commonly found in "sulfate-free" products.

In cosmetics, this ingredient is used to increase the volume of foam, emulsify ingredients, and as a cleansing agent.

As a cleansing agent, sodium lauryl sulfoacetate helps reduce the surface tension of dirt, oil, and other pollutants so they can be rinsed away easily.

Cosmetic Ingredient Review found this ingredient to irritate the eyes and skin in concentrations of 0.18% and 0.7%.

Learn more about Sodium Lauryl Sulfoacetate
Cleansing, Emulsifying, Foaming

Sodium Lauroyl Sarcosinate is a cleansing agent and emulsifier. It is a surfactant derived from sarcosine, and a common source is coconut oil. As a surfactant, Sodium Lauroyl Sarcosinate helps lift dirts, oil, and other molecules to be washed away. In leave-on products, this ingredient is used as an emulsifier. Emulsifier help prevent ingredients such as oils and waters from separating.

Sodium Lauroyl Sarcosinate is also commonly found as a foaming agent in shampoo, toothpaste, and shaving foam. It is amphiphilic, meaning it loves both water and fats.

Emollient, Emulsifying, Skin Conditioning

Glycol Distearate serves as a pearlizing or opacifying agent in cosmetic products.

It's often included in cleansers and haircare products to give them a lustrous or shimmering appearance.

It is derived from stearic acid, a natural fatty acid commonly found in vegetable oils and animal fats.

Glycol Distearate isn't fungal acne safe.

Emulsifying, Emulsion Stabilising

We don't have a description for Cocamide Mea yet.

Buffering, Masking

Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).

As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and even out skin tone.

If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.

We don't have a description for Divinyldimethicone/Dimethicone Copolymer yet.

Masking, Preservative

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 benzoate works as a preservative by inhibiting the growth of bacteria inside of cells. It prevents the cell from fermenting a type of sugar using an enzyme called phosphofructokinase.

It is the salt of benzoic acid. Foods containing sodium benzoate include soda, salad dressings, condiments, fruit juices, wines, and snack foods.

Studies for using ascorbic acid and sodium benzoate in cosmetics are lacking, especially in skincare routines with multiple steps.

We always recommend speaking with a professional, such as a dermatologist, if you have any concerns.

Polyquaternium-7 is a light to clear colored liquid. It is commonly found in haircare products for its film-forming and anti-static properties.

According to a manufacturer, it is a non-paraben and specially developed for negatively charged surfactant systems. This makes it a great hairstyle holder and helps to improve wet hair detangling without adding buildup.

This water-soluble silicone is used for its hydrating and softening properties. It is used to add a silky feel to skincare products and has great benefits for haircare.

In haircare, this ingredient:

  • Adds shine
  • Protects color
  • Offers thermal protection
  • Boosts hair strength
  • Does not build up as easily

Polyquaternium-10 is an ammonium salt of hydroxyethylcellulose. It is a white and granular powder used as a film-former and anti-static agent.

This ingredient is commonly found in hair conditioning products. According to a manufacturer, its positive charge makes it great for absorbing hair proteins. The manufacturer also states this ingredient helps with curl retention.

For haircare friends: this ingredient is not a silicone.

Humectant, Skin Conditioning, Solvent

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.

Preservative

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.

Masking, Perfuming

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.

For instance, Habanolide is a proprietary trade name for a specific aroma chemical. When used as a fragrance ingredient in cosmetics, most aroma chemicals fall under the broad labeling category of “FRAGRANCE” or “PARFUM” according to EU and US regulations.

The term 'parfum' or 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.

For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance by INCI standards.

One example is Calendula flower extract. Calendula is an essential oil that still imparts a scent or 'fragrance'.

Depending on the blend, the ingredients in the mixture can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.

Parfum can also be used to mask or cover an unpleasant scent.

The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.
