Ingredients Explained

Masking, Perfuming, Skin Conditioning

This ingredient is also known as castor oil. It is a skin conditioning ingredient.

The star component of castor oil is ricinoleic acid, an unusual fatty acid that makes up ~80-92% of its composition.

In skincare, it is an emollient that dries down to a solid film with water-binding properties. This helps keep skin hydrated and helps reduce transepidermal water loss (TEWL).

A 2026 dermatology review pulls together its broader uses:

Human clinical testing found this ingredient to be non-irritating and non-sensitizing.

Because castor oil contains fatty acids in the C11-24 range, this ingredient may not be fungal acne safe.

At this time, the literature does not support castor oil in regrowing hair. A 2022 systematic review found no strong evidence that it supports hair growth and only weak evidence that it improves hair shine.

Castor oil itself carries "perfuming" and "masking" function tags according to the official CosIng database. This is because of its mild odor and odor-dampening properties.

Masking, Skin Conditioning

This ingredient is a lightweight emollient, solvent, and texture enhancer. It is considered a skin-softener by helping the skin prevent moisture loss.

It helps thicken a product's formula and makes it easier to spread by dissolving clumping compounds.

Caprylic Triglyceride is made by combining glycerin with coconut oil, forming a clear liquid. Though it behaves like an oil, it is not technically one due to its chemical composition. It is very stable, resistant to oxidation, and unlikely to go rancid. In practice, that translates to a long shelf life and a consistently elegant skin feel.

While there is an assumption Caprylic Triglyceride can clog pores due to it being derived from coconut oil, there is no research supporting this. Be sure to patch test if you have concerns.

Fractionated coconut oil and MCT Oil are both listed as Caprylic/Capric Triglyceride according to INCI. This is because INCI names are based on the ingredient’s final chemical composition and not its marketing name or source.

Emollient, Skin Conditioning

Bis-Diglyceryl Polyacyladipate-2 is a synthetic emollient that works as a lanolin substitute.

This ingredient is a great vegan option for those avoiding animal-derived ingredients.

It mostly stays on the surface of skin where it helps hydrate due to its large molecular size and low water solubility.

Due to it being derived from fatty acids, this ingredient may not be Malassezia or fungal acne safe.

Euphorbia Cerifera wax comes from a shrub in Northern Mexico. It is used to stabilize formulations and has emollient properties.

Emollients form a thin layer on top of skin to prevent water from evaporating, keeping skin and lips hydrated.

According to a manufacturer, this wax can range from a yellow/brown color to translucent.

Abrasive, Absorbent

Silica, also known as silicon dioxide, is a naturally occurring mineral. It is used as a fine, spherical, and porous powder in cosmetics.

Though it has exfoliant properties, the function of silica varies depending on the product.

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.

Emollient, Masking

Octyldodecanol is a fatty alcohol sourced from plant oils like coconut or palm (or made synthetically).

It is:

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.

Emollient

Lanolin Oil comes from lanolin. The solid version of lanolin oil is lanolin wax.

As an emollient, it creates a thin barrier on the skin. This barrier prevents moisture from escaping to keep skin hydrated.

This ingredient may not be Malassezia folliculitis, or fungal acne safe.

Pentaerythrityl Tetraethylhexanoate is an emollient that helps make your skin smooth and hydrated. It specializes in creating a non-oily and "wet" feeling on skin.

This ingredient comes from isostearic acid, a saturated fatty acid. It is a synthetic ingredient.

Emollient, Emulsifying

Cera alba is beeswax, or the wax used by bees to make honeycombs. It is a texture-enhancer and emollient. A study from 2003 found beeswax to be a stronger emollient than ingredients such as petroleum jelly.

As an emollient, beeswax helps hydrate the skin by creating a barrier on top. This barrier traps moisture in.

Emulsifiers help prevent ingredients from separating. This helps create consistent texture.

The structure of beeswax is mainly long-chain alcohols and the esters of fatty acids.

There are three types of beeswax: yellow, white, and absolute. Yellow is pure beeswax taken from the honeycomb. White beeswax is created by filtering or bleaching yellow beeswax. Absolute beeswax is created by treating beeswax with alcohol. Beeswax used in cosmetics are purified.

Beeswax has been used throughout history and even in prehistoric times. Some common uses for beeswax still used today are making candles, as a waterproofing agent, and polish for leather.

Emulsion Stabilising

Microcrystalline Wax is derived from petroleum through a de-oiling process, then highly refined and purified before use in cosmetics.

In skincare formulations, it is used to improve texture and create a smooth, even consistency. It also helps stabilize products by preventing ingredients from separating.

Skin Conditioning, Skin Protecting

Oryza Sativa Bran Extract comes from the outer layer of a rice kernel. It is a byproduct of milling rice, or the operation to produce a whole grain rice product.

This ingredient has moisturizing properties due to its components of polysaccharides and omega-3 fatty acids. It also contains calcium, selenium, phosphorus, iron, and zinc.

Oryza Sativa Bran Extract contains numerous antioxidants such as ferulic acid. Antioxidants help fight free-radical molecules. Free-radical molecules are capable of damaging our cells and other genetic material.

Skin Conditioning

Camellia Oleifera Seed Oil comes from a green tea plant native to China. It is closely related to Camellia sinensis. Both plants have very similar properties. This plant also has similar properties to olive oil.

This ingredient is rich in oleic acid. This makes it an effective moisturizer. By creating a thin film on the skin, Camellia Oleifera Seed Oil traps moisture within. This helps keep your skin smooth and hydrated.

The antioxidant and soothing properties of this ingredient come from Vitamin E and polyphenols.

The seed oil comes from the dried kernels of the plant.

Emollient, Masking, Skin Conditioning

Theobroma Cacao Seed Butter comes from the Theobroma cacoa, or Cacao tree. Cacao trees are native to tropical landscapes.

Like other plant butters, Cacao seed butter is an emollient. Emollients help soothe and soften your skin. By creating a barrier to trap moisture in, emollients help keep your skin hydrated.

Cacao seed butter contains antioxidants known as polyphenols. Antioxidants help fight free-radical molecules by stabilizing them. Unstable free-radicals may cause damage to your skin cells. Antioxidants may help with anti-aging.

Theobroma Cacao Seed Butter can be bad for acne prone skin.

Emollient, Skin Conditioning

Vitis Vinifera Seed Oil comes from the grape vine. Grape seeds are a byproduct of creating grape juice or wine.

The components of grape seeds have many skin benefits. Research has found it to be antimicrobial and anti-inflammatory. It also contains many potent antioxidants such as Vitamin E , Vitamin C, proanthocyanidins, polyphenols, flavonoids, and anthocyanins. Proanthocyanidin has been shown to help even out skin tone.

Antioxidants help fight free-radical molecules. Free-radical molecules are capable of damaging our cells and other genetic material. Antioxidants help stabilize free-radicals by donating extra electrons. Grape seed extract may help reduce the signs of aging.

The antimicrobial properties of grape seed may help treat acne. However, more research is needed to support this claim.

Grape seed has also been found to help absorb UV rays. Grape seed extract should not replace your sunscreen.

The fatty acids of grape seed oil give it emollient properties. Emollients help soothe and soften your skin by creating a film. This film traps moisture within, keeping your skin hydrated.

Skin Conditioning

This ingredient is also known as shea butter. It is a plant-derived extract from the nuts of the Africa shea tree and one of the most well-studied emollients.

Because it has a high concentration of fatty acids (primarily oleic, stearic, and linoleic) it is able to form a protective barrier on the skin's surface. This helps seal in moisture and prevents transepidermal water loss (TEWL).

In vitro research found an increase in skin hydration by 58% and a decrease in TEWL by 37.8% after 24 hours of applying this ingredient (pretty impressive for a single ingredient!).

Besides hydration, shea butter also contains triterpenes that have anti-inflammatory potential. In particule, lupeol cinnamate has shown the highest anti-inflammatory activity in vivo.

Shea butter also contains vitamins A and E which may contribute to antioxidant activity.

While Shea Butter has an SPF rating of about 3-4, it is not a sunscreen replacement.

This ingredient may not be fungal acne safe because its fatty acids fall within the C11-C24 range that the Malassezia yeast can metabolize.

Masking, Skin Conditioning

Carthamus tinctorius seed oil comes from safflower, one of humanity's oldest crops.

Safflower seed oil contains a high percentage of linoleic acid and oleic acid. It also contains Vitamin E. These three components are effective moisturizers.

Vitamin E helps nourish your skin's lipid barrier. It is also a potent antioxidant. Antioxidants help fight free-radical molecules, or unstable molecules that may damage your skin cells.

Due to its high fatty acid content, this ingredient may not be malassezia folliculitis safe.

Thoughout history, safflower has been used for dying fabrics and in food as a saffron substitute.

Masking, Skin Conditioning

Citrus Aurantium Dulcis Peel Oil is oil from the peel of an orange fruit.

Limonene and linalool make up the majority of oils from citrus peels. Limonene has a "citrus" fragrance. Citrus peels also contain flavonoids, which have anti-inflammatory properties.

Citrus peel is also a rich source of flavonoids. Flavonoids are natural antioxidants and help protect your skin against damage. Flavonoids are a group of compounds naturally found in vegetables and fruits.

The term 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term. For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance.

Emollient, Skin Conditioning

Helianthus Annuus Extract comes from the common sunflower.

Sunflowers are rich in vitamin E. Studies show sunflowers contain antimicrobial and antioxidant properties.

The fatty acids found in sunflowers include (from highest amount to least): linoleic acid, myristic acid, palmitic acid, stearic acid, arachidic acid, oleic acid, and linolenic acid.

These fatty acids hydrate your skin. Emollients create a film on the skin to prevent moisture from escaping.

Skin Conditioning

Though this ingredient might sound like a juicy fruit extract, it's actually the fat pressed from the mango seed kernel (or the pit). In skincare, it behaves more like shea butter and cocoa butter than like a plant active.

The fatty acid makeup of mango seed butter makes it special; it's typically rich in stearic acid and oleic acid, with small amounts of palmitic and linoleic acid. This combo helps it melt on skin, feel creamy, and leave behind a protective "seal" that slows down water loss.

It also contains a small amount of "extras" like tocopherols (vitamin E) and phytosterols, which are often used to support skin soothing.

Due to its fatty acid content, this ingredient may not be fungal acne safe.

Rosa Canina Seed Oil comes from the seeds of the dog-rose plant. It is an emollient.

Emollients help hydrate your skin by trapping moisture in. They create a thin film on the skin to prevent moisture from escaping.

Rosa Canina Seed Oil contains phenolic compounds, carotenoids, Vitamin C, linoleic acid, and other fatty acids.

Due to the fatty acid content, this ingredient may not be fungal-acne safe.

Antimicrobial, Masking, Skin Conditioning

This is a botanical extract from the rosemary plant (the same one you cook with). In skincare, it mostly works as a skin conditioning agent.

Its activity comes from a handful of polyphenols, carnosic acid, carnosol, and rosmarinic acid. Almost 90% of the antioxidant activity of this ingredient can be attributed to canosol and carnosic acid.

These compounds protect your skin two ways:

1) They fight off free radicals, or the unstable molecules from things like sun and pollution that age and damage skin.
2) They help calm inflammation by switching off the chemical signals that tell skin to get red and irritated.

Lab studies also suggest that rosmarinic acid may help protect collagen and slow sugar-related damage to it.

The Cosmetic Ingredient Review has concluded rosemary-derived ingredients to be safe when formulated to be non-sensitizing.

Rosemary can occasionally cause allergic contact dermatitis (due to carnosol), so be sure to patch test if you have reactive or fragrance-sensitive skin.

Emollient, Skin Conditioning

Jojoba oil is one of the most well-studied plant-derived ingredients in cosmetics. It is an emollient with a special structure.

Because it is made up of 97-98% wax esters, it closely mirrors the linear monoesters found in human sebum. This makes it skin compatible, non-greasy, and lightweight.

Unlike other plant oils, jojoba wax doesn't easily penetrate skin. It mostly works in the uppermost layers as an emollient. This just means it forms a light barrier on the skin to help retain moisture.

Formulations with jojoba esters up to 90% reduced transepidermal water loss (TEWL) and increased barrier recovery by 81% (outperforming bisabolol at 47%).

Besides barrier support, the science also suggests jojoba to have anti-inflammatory effects and potential applications for skin infections, aging, and wound healing.

Fun fact: Indigenous cultures have used jojoba as a moisturizer and to help treat burns for centuries.

Due to its fatty acid content, Jojoba oil may not be fungal acne safe.

Antioxidant, Masking, Skin Conditioning

Tocopherol is a fat-soluble antioxidant known as Vitamin E.

You'll find this ingredient in the vast majority of skincare (for good reason). It works to neutralize free radicals, or unstable molecules generated by UV exposure, pollution, and other environmental stressors, before they can cause oxidative damage to your skin cells.

Topically applied tocopherol has been shown to protect against UV damage by ramping up the skin's own natural defense enzymes.

It also acts as a skin conditioning agent; some studies show that regular topical use can improve the skin's water-binding capacity over 2-4 weeks.

This ingredient is especially loved for being a team player. When combined with Vitamin C, the photoprotective effect of both ingredients roughly doubles and the combo also helps reduce UV-induced DNA damage.

This ingredient has some brightening potential but it's more of a prevention ingredient than spot-fader. Cell studies show it can slow down melanin production but it's worth noting that it's not the most powerful brightener out there.

In formulations, it also serves as a stabilizer that helps protect other oxidation-prone ingredients from degrading.

Concentrations usually range from 0.1-1% in most leave-on products.

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.

Skin Conditioning

Ethylhexylglycerin is created from glycerin. It is a multitasker ingredient that:

The CIR Expert Panel found minimal skin absorption or sensitization of any kind in a safety assessment. Though this ingredient is considered well-tolerated, a small number of cases of allergic dermatitis have been published since 2002. Just be sure to patch test if you are unsure.

Industry-reported use ranges from 8% in rinse-off products and 2% in leave-on formulations.

Emollient, Humectant, Skin Conditioning

Caprylyl Glycol is a humectant, skin conditioner, emollient, and preservative booster derived from either caprylic acid or synthetically created.

Typical use levels vary from 0.3-1% as a preservative booster and go up to 2% to condition skin.

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

Limonene is a fragrance that adds scent and taste to a formulation.

It's found in the peel oil of citrus fruits and other plants such as lavender and eucalyptus. The scent of limonene is generally described as "sweet citrus".

Limonene acts as an antioxidant, meaning it helps neutralize free radicals.

When exposed to air, oxidized limonene may sensitize the skin. Because of this, limonene is often avoided by people with sensitive skin.

The term 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term. For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance.
