Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Ascorbyl Palmitate is a fat-soluble form of vitamin C (Ascorbic Acid) made by combining it with palmitic acid.
It is able to blend easily into creams and oil-based formulas because it dissolves in oils rather than water.
As you may know, regular vitamin C is notorious for breaking down when exposed to sunlight and air. Ascorbyl Palmitate is more stable and degrades at a slower rate.
Research on whether it converts efficiently into active vitamin C once it's applied on your skin is still limited. Some in-vitro studies suggest it may support collagen production, but it is not considered one of the stronger vitamin C derivatives, like:
Due to the palmitic acid base, this ingredient may not be fungal acne safe. Comedogenic studies have also shown this ingredient to have a rating of 2.
It's also worth keeping in mind that comedogenic and irritancy ratings are tested on individual ingredients, not finished formulas. The final product's formulation, concentration, and other ingredients all play a role in how something actually behaves on your skin.
Learn more about Ascorbyl PalmitateThis 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.
Learn more about Caprylic/Capric TriglycerideEthylhexyl Palmitate, also known as octyl palmitate, is created from 2-ethylhexyl alcohol and palmitic acid. It is a fatty acid ester.
The fatty acid content of Ethylhexyl Palmitate makes it an emollient. Emollients help soften and hydrate your skin by trapping moisture within.
Ethylhexyl Palmitate is also used to help improve the texture of cosmetics. It helps other ingredient dissolve in products and help disperse ingredients more evenly.
You'll likely find this ingredient in sunscreen, as it is often used to mix UV-blocking ingredients such as avobenzone and ethylhexyl triazone.
It can also help stabilize the fragrances in a product as a fragrance fixative.
Ethylhexyl Palmitate can be used to substitute mineral oil.
Due to its high fatty acid content, it may not be fungal-acne safe.
Learn more about Ethylhexyl PalmitateThis ingredient comes from a fatty acid (lauric acid) and amino acid (lysine). It is used to add a silky feel to cosmetics.
According to a manufacturer, its fatty acid base leaves a silky feeling on the skin. It also has emollient properties because of this. Emollients help soften skin by preventing water from evaporating.
Lauroyl lysine is barely soluble in water.

Methicone is a type of silicone and is a simpler form of dimethicone.
Silicones are used to enhance the texture of products and have emollient properties. Methicone is used to give products a silky texture and improves spreadability.
Nylon-12 is a polymer. It is derived from 12-aminododecanoic acid, an omega-amino fatty acid
According to a manufacturer, it is a talc substitute. Like talc, nylon-12 gives products a satin feel. The manufacturer also claims this ingredients does not block pores and has moderate oil absorption.
This ingredient may not be reef-safe.
Learn more about Nylon-12This ingredient is also known as PMMA. It is a polymer microsphere, composed of tiny, perfectly spherical particles formed from repeating units.
In cosmetics, PMMA is mainly used to give a soft or blurring effect. The transparent particles are able to scatter light and help reduce the appearance of fine-lines and imperfections.
PMMA is also able to enhance the texture of products by add a smooth feel.
Learn more about Polymethyl MethacrylateThis ingredient is a preservative with antimicrobial properties. It is the sodium salt of dehydroacetic acid.
It is especially effective at preventing bacterial and fungal growth in low concentrations.
Talc is a clay mineral. It helps absorb moisture and improve the texture of products. Like other types of clay, Talc can have a slight exfoliating effect on skin. Talc can be added to increase the volume of products.
Some Baby powders are made by combining talc with corn starch. The word "talc" comes from Latin and originates from Arabic. Talc is a mineral commonly found throughout the world.
If you have any concerns about using talc, we recommend checking out the FDA's official page.
Learn more about TalcZea Mays Starch is starch made from corn. You might know this as cornstarch . It is used to thicken a product. It can replace talc as an absorbent.
The pH of cornstarch is 5.92.
Cornstarch is a common food ingredient used to thicken soups or to make corn syrup.
Learn more about Zea Mays StarchThis ingredient is a combination of red, black, and yellow iron oxide pigments. This combination of colors is usually found in foundation, because it results in a "skin" color.
The EU typically uses CI numbers for colorants when applicable, such as CI 77489. In the US, iron oxides are regulated as color additives and "iron oxides" is the most commonly used name in US cosmetic practice.
A 2021 paper looked at skincare formulations containing iron oxides and found that they reduced transmission of blue light when measured optically. In simple terms, the pigment particles helped block or scatter part of the visible light spectrum in lab testing and the authors suggest this could translate into better protection against blue-light-related skin effects.
There is also clinical and experimental research showing that tinted products containing iron oxides can reduce visible light-induced pigmentation:
Please note, whether a product reduces visible or blue light depends on things like:
In the EU's CosIng database, iron oxides are only listed as a colorant. CosIng groups ingredients by their main cosmetic role, such as colorant, preservative, or UV filter.
Though studies say iron oxides can "attenuate blue light", they're describing an optical property and not an officially recognized cosmetic function.
So CosIng isn’t contradicting the research. It’s just classifying iron oxides by what they officially are: pigments that add color.
