Coralhaze Idol Aegyo-Sal Maker

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.

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

It is considered non-comedogenic and vegan-friendly.

This ingredient has a well-established safety record by the CIR Expert Panel for Cosmetic Ingredient Safety.

Synthetic Waxes are straight/branched-chain hydrocarbons with no ester bond or fatty acids. That means there is nothing for the Malassezia yeast to feed on.

It is considered non-irritating on the skin.

Isododecane's role as a solvent makes it a great texture enhancer. It spreads smoothly on skin and does not leave a sticky feeling behind. Isododecane also helps prevent color transfer in makeup products.

Isododecane is not absorbed into skin.

The chemical name for this ingredient is 2,2,4,6,6-PENTAMETHYLHEPTANE.

The cosmetic grade stuff is highly refined with a solid safety record. The CIR Expert Panel has repeatedly reaffirmed this ingredient to be safe in current practices of use and concentration.

The worry about carcinogenic compounds only applies to industrial grades, not the purified version used in skincare.

Despite its reputation, the highly reformed form is non-comedogenic and doesn't penetrate deeply into skin.

The good news for fungal-acne prone folks: the Malassezia yeast feeds on fatty acids and lipids and paraffin doesn't contain any of these (so there's nothing for the yeast to metabolize). This ingredient is considered fungal acne safe.

Zinc Stearate is hydrophobic and repels water.

This ingredient can be sourced from non-animal or animal sources. It is best to reach out to the brand to see where they source this ingredient from.

This ingredient is generally safe for use in cosmetics with one nuance: some grades of candelilla wax can naturally contain benzyl alcohol at concentrations high enough to require declaration under EU labeling rules. This isn't a concern for most people but relevant for those with fragrance sensitivities.

Candelilla wax contains fatty acids (mainly C31) and wax esters that can be used by the Malassezia yeast, so this ingredient may not be fungal acne safe.

You might see Euphorbia Cerifera "Cera" instead of "wax". This is because some brands, databases, or labels use it interchangeably; they're the same ingredient.

You'll likely see this in many BHA products because this is the go-to solvent for salicylic acid.

This ingredient is typically used at levels between 2-20%.

Regarding fungal acne:
In 2019, this ingredient was tested against multiple Malassezia species (the yeast that causes fungal acne) and showed no growth.

Synthetically created Ci 77491 is considered safer than those naturally found. This is because the synthetically created version may contain less impurities. Iron oxides are generally non-toxic and non-allergenic.

Hectorite is a rare, white clay mineral.

As a co-emulsifier, its "head" and "tail" sit at the oil-water interface. But overall, the short C8 tail and not being water soluble means it doesn't really have the muscle to emulsify a formula on its own. That's why you'll often see it paired with a primary emulsifier like Cetearyl Glucoside.

Interestingly, Glyceryl Caprylate acts as a preservative booster. This is because its fatty-acid backbone disrupts microbial lipid membranes. It shows excellent activity against bacteria and yeast but is weaker against mold.

Typical concentrations range from 0.5-1% and this ingredient is generally non-irritating.

Because this ingredient has a C8 fatty acid chain, it is outside the range that the Malassezia yeast metabolizes (making it fungal acne safe).

Because it is not a free-fatty acid, this ingredient is fungal acne safe (there's nothing for Malassezia to feed on).

Studies show this ingredient to be safe for cosmetics. When it is undiluted, it can cause skin irritation. (It is always diluted in skincare and makeup). This ingredient is water-soluble.

Propylene Carbonate is created from propylene glycol and carbonic acid.

This is due to how structurally similar it is to what your skin already produces.

Though it is mostly an emollient that helps soften and hydrate skin, it also has some humectant and occlusive action. Humectants help the skin retain moisture while occlusives seal it in, making squalane a triple-threat moisturizer.

Research shows it has antioxidant capabilities that help protect against stressors like UV exposure, specifically UVA induced oxidative stress. This study also found that it supports collagen biosynthesis in human dermal fibroblasts.

No clinical study has reported significant adverse effects and irritation reactions are very rare from this ingredient (even at 100% concentration).

Overall, it's a fantastic ingredient for hydration and is suitable for all skin types.

This depends on the source. Squalane can be derived from both plants and animals. Most squalane used in skincare comes from plants.

Please note: the source of squalane is only known if disclosed by the brand. We recommend reaching out to the brand if you have any questions about their squalane.

Though squalane is often called an oil, it’s technically not one. It is a hydrocarbon, meaning it is only made of carbon and hydrogen. True oils are triglycerides and made of fatty acids and glycerol.

The term “oil-free” isn’t regulated so companies can define it however they want. Some exclude all oils, while others just avoid mineral oil or comedogenic oils.

Squalane has a comedogenic rating of 1 from the original 1972 study that tested raw ingredients under occlusion on rabbit ears. This system is not standardized or peer-reviewed, and using the raw ingredients is very different from how diluted cosmetic formulations are used on human skin.

A comedogenic rating of 1 means it is "unlikely to clog pores" according to the original rating system.

The overall formula of a product matters more than the individual ingredients on whether or not it will cause clogged pores.

Unsaponifiables have high antioxidant potential due to the tocopherols, carotenoids, and phenolic acids that help protect skin from free radical damage. On the other hand, linoleic acid supports the skin's barrier by replenishing ceramides and reducing transepidermal water loss.

A manufacturer-sponsored clinical study found that a cream with 2% of this ingredient increased skin moisturization by 48.6% after 1 hour and 34.2% after 24 hours.

Using this cream twice-daily for 4 weeks showed meaningful improvement in dryness, roughness, and desquamation (the shedding of dead skin cells).

Keep in mind this is a small, industry-funded study so it'd be great to see independent replication. However, the mechanism is consistent with well-establish linoleic and phytosterol research.

While this ingredient is generally considered safe, those with an Asteraceae/Compositae plant allergy should patch test this ingredient.

Fungal acne: this ingredient is not considered safe for fungal acne because the Malassezia yeast preferentially metabolizes in the C11-24 range. Linoleic acid falls into this range at C18.

As an emollient, it helps trap moisture in the skin. It is considered an occlusive.

Synthetically created CI 77492 is considered safer than those naturally found. This is because the synthetically created version may contain less impurities. Iron oxides are generally non-toxic and non-allergenic.

The term "Hydrogenated Vegetable Oil" is an umbrella term and can refer to a variety of vegetable oils and blends of: sunflower oil, soybean oil, olive oil, coconut oil, palm oil, and more.

Due to the differences in vegetables, the benefits may vary.

You'll typically find this ingredient in amounts between 0.1-20%.

Polyisobutene is not absorbed by the skin.

Depending on the concentration, it can drastically change the texture of a product from pasty solid (like lipstick) to sprayable liquid.

The CIR Expert Panel for Cosmetic Ingredient Safety has concluded this ingredient to be safe in cosmetics. The highest reported use concentration is 14.2% in lipsticks.

It plays well with most ingredients and is typically used at 0.1-1%. However, concentrations up to 50% have been reported in moisturizers.

This ingredient is typically used at low levels (up to 2.5% in eyeshadow and 1% in lipstick).

One thing worth noting: a controlled study found this ingredient applied under occlusion to acne-prone subjects increased microcomedones. Just keep in mind this was under occlusive conditions and don't reflect how most products are used day-to-day.

For most people, this is a well-tolerated and lightweight ingredient.

This ingredient may not be fungal acne safe because it is an ester of palmitic acid, a C16 fatty acid that falls within the C11-24 range that Malassezia can metabolize.

This ingredient is sourced from plant-based oils like soybean or rapeseed.

Clinical studies found no signs of irritation from this ingredient.

Since Isostearic Acid is an 18-carbon fatty acid, it is in the range that Malassezia can feed on. This ingredient may not be fungal acne safe.

You might have seen sources that this ingredient is comedogenic. The original comedogenic testing on rabbit ear actually tested the ester, Isopropyl Isostearate and not Isostearic acid itself. There has been no comedogenic testing done on this ingredient, but it may be worth patch testing if you have acne-prone skin.

This ingredient is generally considered non-toxic, non-irritating, and has low absorption potential.

You might have heard that this ingredient clogs pores. This reputation comes from the older rabbit ear studies which are more sensitive than human skin to clogging.

Dermatologist Dr. Zoe Draelos has also confirmed in a peer-reviewed paper that products containing comedogenic ingredients are not necessarily comedogenic themselves.

A small subset of people (~2%) may experience contact sensitivity so patch testing is a reasonable idea if you have reactive skin.

Since this ingredient is an ester of myristic acid (a C14 fatty acid), it falls within the carbon chain range that is known to feed Malassezia. This ingredient may not be fungal acne safe.
