Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Benzalkonium Chloride (aka BAC) is a preservative that has been around since the 1930's. It is also a surfactant that gives it mild cleansing and antistatic properties.
BAC works because it carries a positive electrical charge that attract the negative charge of microbe cells (like a magnet). Once BAC sticks to a microbe, it breaks the microbe cell's outer wall and scrambles its proteins to kill it.
The maximum usage percentage for this ingredient is 0.1% in both the EU and Chinese cosmetic regulations.
The CIR Expert Panel has concluded it to be a safe antimicrobial agent in concentrations up to 0.1% and it is permitted up to 3% in rinse off hair products.
BAC can be irritating at higher concentrations but a true allergy to it is pretty rare. Be sure to patch test if you have a damaged skin barrier or just sensitive skin.
Because it's a cation, it is incompatible with anionic surfactants like SLS (they neutralize each other).

This ingredient has been deemed safe for use in cosmetic formulations at concentrations up to 5%, and up to 10% in hair dyes. You'll typically see 0.5-2% in most rinse-off or leave-on products.
As a preservative, it works by disrupting the membrane of microbial proteins. This helps keep bacteria and fungi from growing in your products.
The sensitization picture is actually quite assuring as well:of nearly 71,000 patients patch tested with benzyl alcohol, only 0.21% showed a positive reaction with most of them being weakly positive.
This led researchers to conclude that benzyl alcohol cannot be regarded as a significant contact allergen.
It is worth noting this ingredient is classified as one of the EU's regulated fragrance allergens and restricted to 1% in finished products.
Labels must also declare it in concentrations above 0.001% in leave-on products and 0.01% in rinse-off products.
At concentrations around 5%, localized redness and itching can appear as a direct irritant response and not as a true allergic reaction.
Learn more about Benzyl AlcoholCyclopentasiloxane, or D5, is a silicone used to improve texture of products and trap moisture.
D5 is considered lightweight and volatile. Volatile means it evaporates quickly after application. Once evaporated, D5 leaves a thin barrier that helps keep skin hydrated.
It is also an emollient. Emollients help soften the skin and prevent water loss. Silicones create a silky texture in products. D5 helps other ingredients become more spreadable.
Studies show D5 is safe to use in skincare products. We recommend speaking with a skincare professional if you have concerns.

This ingredient is soluble in water.
Potassium Phosphate is the term for the salts of potassium and phosphate ions. Our bodies naturally create and use potassium phosphate.
In cosmetics, potassium phosphate is used to adjust the pH level of products. Our skin has a natural pH level. Maintaining this pH level is important for our skin barrier. If the skin barrier is disrupted, our skin can experience dehydration and irritation.
This ingredient is used in medicine to help treat low blood levels of phosphorus.

You'll most likely find this ingredient in cleansers where it is used to create a gel-like texture. As an emulsifier, it also prevents ingredients from separating.
You might see people debate whether Sodium Chloride is comedogenic, but there actually haven't been any comedogenic tests done on it. Either way, the overall formulation of a product matters a lot more than any single ingredient.
You might see this ingredient used in scrubs as a primary exfoliating ingredient.

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. Remember to stay hydrated!
