ISANA Lippenpflege

Older ingredient lists label it as "Octyl Stearate" and it turns up the most often in makeup products.

Industry data shows usage concentration goes up to ~40% in makeup and up to 10% in moisturizer or sunscreen.

Human repeat insult patch tests with a 25.9% lip gloss and 38.8% eyebrow pencil found no sensitization. A formula with 7.6% was also not an irritant, sensitizer, and was found to be non-phototoxic across 56, 19, and 27 subjects respectively.

True contact allergy to it is rare.

This ingredient shows up on a lot of "pore-clogging" lists but there's no real evidence behind that. It doesn't even have a comedogenic rating from an actual study; the numbers you'll find online come from blogs citing other blogs.

Ratings for other ingredients mostly come from a 1980s rabbit ear test. This test doesn't translate well to human skin or to real products because the ingredient sits at a much lower percentage.

Some people still find it breaks them out. So if that's you, definitely trust your skin.

The Malassezia yeast has been found to grow in the presence of fatty acids, fatty acid esters, and fatty alcohols with chains longer than 12 carbons. Ethylhexyl Stearate releases stearic acid, an 18-carbon chain, which is right inside that range; this ingredient may not be fungal acne safe.

In comedogenic testing, Beeswax scored a 0-2, which is on the low end. Whether or not a product clogs your pores really comes down to the formula as a whole (not any single ingredient on its own) and your skin.

Beeswax is not vegan since it is animal-derived. It cannot be removed with water, but can be taken off with an oil cleanser.

People with a known Propolis allergy also report to have reactions from beeswax.

Beeswax's wax esters are derived primarily from palmitic and oleic acid (C16 and C18:1). Both of these fall within the C11-C24 feeding window.

The Malassezia yeast can potentially cleave these esters and release usable fatty acids, so this ingredient may not be fungal acne safe. However, not everyone will react to this ingredient.

This ingredient is often coated with metal oxides like titanium dioxide. Trace amounts of heavy metals may be found in mica, but these metals are not harmful in our personal products.

Mica has been used since prehistoric times throughout the world. Ancient Egyptian, Indian, Greek, Roman, Aztec, and Chinese civilizations have used mica.

Safety-wise, the CIR Expert Panel has concluded it to be safe in cosmetics when formulated to be non-irritating and non-sensitizing.

Free stearic acid is a C18 fatty acid that the Malassezia yeast can substrate, so this ingredient may not be fungal acne safe.

This ingredient does have a comedogenic rating of 2-3, 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.

Preclinical research has found that topical avocado oil increased collagen synthesis and reduced inflammation during wound healing, giving it some skin-repairing credibility.

The unsaponifiable fraction of the oil is also interesting: studies on avocado unsaponifiables showed that it helped skin produce more collagen and other structural compounds that support healing.

The CIR Expert Panel has found this ingredient to be non-irritating in formulations.

This ingredient may not be fungal acne safe. This is because the oleic acid content falls within the range that Malassezia can use as a food source.

This ingredient does have a comedogenic rating of 0-3, but this doesn't mean a formula with this ingredient will clog pores. Human testing has proved that any finished product with a comedogenic ingredient won't automatically make you break out; it really comes down to concentration, formula, and your skin.

Here is the official definition from the The International Cosmetic Ingredient Dictionary and Handbook:

“Aroma is a term for ingredient labeling used to identify that a product contains a material or combination of materials normally added to a cosmetic to produce or to mask a particular flavor.”

INCI shows the only purpose of aroma to be "flavouring".

However, due to regulation differences, some companies may use aroma in place of parfum.

In Canada, this ingredient only has to be listed in concentrations above 1%.

Ci 77891 is commonly found in sunscreens due to its ability to block UV rays.
