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, Emulsion Stabilising

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.

This ingredient is biodegradable and non-toxic. This ingredient is commonly found in baby shampoos.

Decyl Glucoside is sometimes used to stabilize the UV filter Tinosorb.

Learn more about Decyl Glucoside
Antioxidant, Skin Conditioning

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.

Tocopheryl Acetate is commonly found in both skincare and dietary supplements.

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.

Emollient, Emulsifying, Perfuming

Glyceryl Oleate is the ester of glycerin and oleic acid. This ingredient is mainly an emollient and emulsifier.

Emollients soften and hydrate the skin by creating a thin film on top to trap in moisture. As an emulsifier, glyceryl oleate helps stabilize formulations by preventing ingredients such as oil and water from separating. According to a manufacturer, this ingredient helps helps thicken water-in-oil formulations, shower gels, and hair shampoos.

In some products, this ingredient may be used as a fragrance / perfuming ingredient. The scent of this ingredient is described to be "waxy".

Glyceryl oleate is created from oils rich in oleic acid, such as peanut oil and olive oil.

This ingredient may not be malassezia folliculitis safe.

Antimicrobial, Astringent, Masking

Alcohol comes in many different forms. Different types of alcohol will have different effects on skin. This ingredient is usually an astringent alcohol.

These alcohols are drying on the skin. They may strip away your skin's natural oils and even damage your skin barrier. Astringent alcohols may also irritate skin.

Other types of astringent alcohols include:

According to the National Rosacea Society based in the US, you should be mindful of products with these alcohols in the top half of ingredients.

Any type of sanitizing product will have high amounts of alcohol to help kill bacteria and viruses.

Fatty alcohols come from plant oils such as coconut oil. These can help hydrate the skin and are non-irritating. Some fatty alcohols include cetyl and stearyl alcohol.

Preservative

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.

Both potassium sorbate and sorbic acid can be found in baked goods, cheeses, dried meats, dried fruit, ice cream, pickles, wine, yogurt, and more.

You'll often find this ingredient used with other preservatives.

Learn more about Potassium Sorbate
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.

Good and cheap! Recommend a double-wash of the scalp/roots only (suds will automatically wash the mids and ends of the hair). Do not condition the roots after (only the mids and ends). This will make it so you only have to wash your hair every 3 days or longer
