Ingredients Explained

Oryza Sativa Starch is an absorbent and used to mattify the skin. It is a natural carbohydrate and the main component of rice. A more common name for this ingredient is 'rice starch'.

Rice starch is created by steeping broken grains in a caustic soda.

Rice extract has many skin benefits. Read more about rice extract here.

Hydrogenated Castor Oil (aka "castor wax") is what you get when castor oil is turned into a wax.

Its dominant fatty acid is ricinoleic acid, giving it both emollient and mild humectant properties.

According to EU CosIng, this ingredient helps soften skin, keep oil and water stay mixed, and thickens products.

Hydrogenated castor oil at 30% did not trigger a positive patch-test reaction and is well-tolerated.

Since this ingredient is based on an 18-carbon fatty acid, it falls into the chain-length range that Malassezia can feed on and may not be fungal acne safe.

Sodium Bicarbonate has a more famous name: Baking soda.

In cosmetics, it is used to adjust the acidity. Due to its white crystalline solid form, it can also be an abrasive (exfoliator).

This ingredient is water-soluble.

Citric Acid is an alpha hydroxy acid (AHA) naturally found in citrus fruits like oranges, lemons, and limes.

Like other AHAs, citric acid can exfoliate skin by breaking down the bonds that hold dead skin cells together. This helps reveal smoother and brighter skin underneath.

However, this exfoliating effect only happens at high concentrations (20%) which can be hard to find in cosmetic products.

Due to this, citric acid is usually included in small amounts as a pH adjuster. This helps keep products slightly more acidic and compatible with skin's natural pH.

In skincare formulas, citric acid can:

While it can provide some skin benefits, research shows lactic acid and glycolic acid are generally more effective and less irritating exfoliants.

Most citric acid used in skincare today is made by fermenting sugars (usually from molasses). This synthetic version is identical to the natural citrus form but easier to stabilize and use in formulations.

Hydrated Silica is a type of silicon dioxide. It is called 'hydrated silica' because it is silica with extra bonded water atoms.

It is an absorbent and abrasive, meaning it is exfoliating.

Silica is often used for absorption and can help reduce shine when products are applied.

This ingredient is also known as sea fennel. It is a coastal plant extract with plant compounds like chlorogenic acid. This plant contains both "water" and "oil" parts.

One small human study (12 people over the age of 50) found formulas containing sea fennel biomass showed faster recovery of barrier function / TEWL after the barrier was deliberately disrupted.

A 2025 paper reported improved markers of regeneration in a UV-weakened full-thickness skin model using both water and oil parts. Markers include thicker epidermis, higher loricrin, and more collagen-related signals compared to an oil-only extract.

Broader phytochemical reviews describe antioxidant and anti-inflammatory activity in experimental models.

The plant's essential oil side can contain fragrant terpenes that can irritate sensitive skin, but many skincare formulas focus more on antioxidants like chlorogenic acid.

Caprylic/Capric Triglyceride (aka MCT Oil) is a lightweight emollient, solvent, and texture enhancer. It is considered a skin-softener by helping to prevent moisture loss.

Though it behaves like an oil, it is not technically one due to its chemical composition. One perk of this ingredient is that 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. Just 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.

This ingredient is treated as the gold standard fungal acne safe oil. Even though it is coconut derived, the problematic lauric acid is stripped out.

This leaves just caprylic (C8) and capric (C10) acid. These chain lengths actually trend antifungal; a 2020 study found caprylic acid was enough to disrupt Malassezia furfur cell membrane, with a caprylic acid derivative damaging membrane structures at concentrations as low as 0.2%.

Parfum is a catch-all term for an ingredient or more that is used to give a scent to products.

Also called "fragrance", this ingredient can be a blend of hundreds of chemicals or plant oils. This means every product with "fragrance" or "parfum" in the ingredients list is a different mixture.

For instance, Habanolide is a proprietary trade name for a specific aroma chemical. When used as a fragrance ingredient in cosmetics, most aroma chemicals fall under the broad labeling category of “FRAGRANCE” or “PARFUM” according to EU and US regulations.

The term 'parfum' or '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 by INCI standards.

One example is Calendula flower extract. Calendula is an essential oil that still imparts a scent or 'fragrance'.

Depending on the blend, the ingredients in the mixture can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.

Parfum can also be used to mask or cover an unpleasant scent.

The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.
