Nooni Snowflake Whipping Cleanser Versus bareMinerals Poreless Clay Cleanser

This ingredient is considered safe at present practices of use and concentration and repeated insult patch test with 50% Glycol Distearate on 125 subjects found no evidence of skin irritation, hypersensitivity, or acute toxicity.

Typical use concentrations range from 0.1-10%.

Because it's an ester of stearic acid, it falls into the range that Malassezia likes to metabolize. This ingredient may not be fungal acne safe.

Most kaolin is a white color, but may be pink/orange/red depending on where it comes from.

The name 'kaolin' comes from a Chinese village named 'Gaoling'. Kaolin clay comes from rocks rich in kaolinite. Kaolinite, the mineral, has a silicate layered structure. Kaolinite is formed from chemical weathering of aluminum siilicate minerals.

Besides skincare, kaolin is commonly used to make glossy paper, in ceramics, toothpaste, and as medicine to soothe stomach issues.

Research indicates that this ingredient posts a low risk of irritation and sensitization.

Industry survey data collected for this ingredient puts real-world usage concentrations anywhere from 0.00002% to 20% (most of the high end sits in rinse-off products).

Myristic Acid is not a recognized contact allergen and there are no published case reports of allergic contact dermatitis to it. Human testing found it to be non-irritating at 100% and at 40-50% in mineral oil. There are complaints about high-Myristic-acid cleansers leaving a tight feeling behind, but that has more to do with soap chemistry and pH than an allergy.

This ingredient does have a comedogenic rating of 3, but this doesn't mean a formula with this ingredient will clog pores.

Human testing has proved that any finished product with this ingredient won't automatically make you break out; it really comes down to concentration, formula, and your skin. Some people still find it breaks them out. So if that's you, definitely trust your skin.

Since myristic acid is a C14 fatty acid, it falls within the range that Malassezia can metabolize (C11-24), and therefore may not be fungal acne safe.

Japanese manufacturers will sometimes call this ingredient PEG 1540.

On a cellular level, it disrupts the cell membranes of microbes by poking holes that make the cell leak. This shuts down the chemical reactions the microbe needs to make energy so it can no longer survive.

Another perk of this ingredient is that it stays functional across a wide pH range (3-10).

You'll often see it paired with boosters like Ethylhexylglycerin; one study showed that a 1:9 ratio of Ethylhexylglycerin to Phenoxyethanol damages bacterial membranes as effectively as doubling the Phenoxyethanol concentration on its own.

Typical use concentrations range from 0.3-1% depending on the formula, and this ingredient is capped at 1% int the EU.

Safety-wise, the fear mongering does not hold up to the evidence. The EU's Scientific Committee on Consumer Safety and FDA consider it safe as a preservative at up to 1%, including for children of all ages.

Adverse systemic effects only showed up in animal studies at exposures roughly 200x higher than what people get from cosmetics. And despite its very widespread use, this ingredient is a rare sensitizer and allergic reactions are uncommon.

An expert safety panel reviewed it and found it safe when formulations are made to be non-irritating.

As a pH adjuster, it's typically used well under 1% though regulatory caps go much higher: 5% in nail cuticle removers and 2-4.5% in hair straighteners.

Though there is some concern for irritation from raw or high pH material, a well-balanced formula will be a non-issue for the vast majority of people.

The unique structure of silica enhances the spreadability and adds smoothness, making it a great texture enhancer.

It is also used as an active carrier, emulsifier, and mattifier due to its ability to absorb excess oil.

In some products, tiny microneedles called spicules are made from silica or hydrolyzed sponge. When you rub them in, they lightly polish away dead skin layers and enhance the penetration of active ingredients.

It is able to lift away oil and grime and make a nice lather without stripping your skin, so it's a good pick for sensitive skin.

Safety-wise, it has a good record. The CIR Expert Panel has concluded this ingredient to be safe in cosmetics and concentrations go up to 11% in leave-on products or 13% in rinse-off products.

Despite being derived from coconut oil, this ingredient is fungal acne safe. It's a water-soluble surfactant with no fatty oils or esters left intact on skin for the Malassezia yeast to feed.

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!
