Ingredients Explained
Diisostearyl Malate is an emollient and most often used in lip products. It comes from isostearyl alcohol, a fatty acid, and malic acid, an AHA.
As an emollient, Diisostearyl Malate helps create a thin film on your skin to trap moisture in. This helps keep your skin soft and smooth.
C12-15 Alkyl Benzoate is made up of Benzoic Acid and long chain alcohols. It has a low molecular weight.
C12-15 Alkyl Benzoate is an emollient and texture enhancer. Due to its solubility, it is often used in sunscreens to help evenly distribute active ingredients.
As an emollient, C12-15 Alkyl Benzoate helps soften and hydrate your skin. Emollients create a film on your skin that traps moisture within.
This ingredient has been reported to cause eye irritation.
Learn more about C12-15 Alkyl BenzoatePentaerythrityl Tetraisostearate is derived from isostearic acid. It is an emollient and emulsifier.
The highest concentration of this ingredient is found in lipsticks.
This ingredient is minimally water soluble and may not be Malassezia folliculitis, or fungal-acne safe.
Learn more about Pentaerythrityl TetraisostearateOctyldodecanol is a fatty alcohol. It is primarily used to enhance the texture of products.
As an emulsifier, Octyldodecanol helps prevent the oils and waters from separating. It also prevents ingredients from creating foam when shaken.
Octyldodecanol is created by reducing fatty acid to an alcohol.
Due to its high molecular weight, it does not get absorbed into the skin.
Learn more about OctyldodecanolSynthetic Wax is created from fossil fuels such as natural gas. It is used to enhance texture, adjust pH, and as an occlusive.
It may also be used as an abrasive ingredient to exfoliate the skin.
Synthetic Wax may not be fungal acne safe.
Learn more about Synthetic WaxPolyisobutene is a synthetic polymer made from isobutene.
It is a film-forming agent and helps bind ingredients together.
Polyisobutene is not absorbed by the skin.
Learn more about PolyisobutenePhenyl Trimethicone is a silicon-based polymer. It is derived from silica.
Phenyl Trimethicone is used as an emollient and prevents products from foaming.
As an emollient, it helps trap moisture in the skin. It is considered an occlusive.
Learn more about Phenyl TrimethiconeBeeswax is natural wax produced by honey bees and can be synthetically created. It consists mainly of fatty acid esters and long-chain alcohols.
In cosmetics, beeswax is a emollient. Due to its waxy structure, it creates a protective barrier. This barrier prevents water from evaporating off the skin.
This may not be a good ingredient for oily skin. We recommend speaking with a professional if you have concerns.
Beeswax cannot be removed with water, but can be taken off with an oil cleanser.
Beeswax is also antiseptic and contains vitamin A.
Learn more about BeeswaxCi 77891 is a white pigment from Titanium dioxide. It is naturally found in minerals such as rutile and ilmenite.
It's main function is to add a white color to cosmetics. It can also be mixed with other colors to create different shades.
Ci 77891 is commonly found in sunscreens due to its ability to block UV rays.
Learn more about CI 77891Microcrystalline Wax is created by de-oiling petroleum. It is highly refined and purified before being added to cosmetics.
Microcrystalline Wax is used to enhance the texture and create even consistency. It helps stabilize a product by preventing ingredients from separating.
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.
Learn more about Tocopheryl AcetateMica refers to a group of silicate minerals. Mica crystals are easily split to give products a shimmer. These crystals are able to reflect light to temporarily give your skin a glowy look.
Mica is found to be safe. 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.
Mica can be naturally found throughout the world. However, some sources of mica may be controversial. In 2016, mica mined in the Jharkhand state in India was found to be using child labor. However, companies are able to source ethical mica affiliated with international organizations that monitor the mica supply chain.
Learn more about MicaPolyethylene is a synthetic ingredient that helps the skin retain moisture. It is a polymer.
It is also typically used within product formulations to help bind solid ingredients together and thicken oil-based ingredients. When added to balms and emulsions, it helps increase the melting point temperature.
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 āFRAGRANCEā or āPARFUMā 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.
Learn more about ParfumTitanium dioxide is a mineral UV filter widely used in sunscreens and cosmetics.
It is one of only two UV filters officially classified as āmineralā by regulatory agencies, the other being zinc oxide.
Titanium dioxide provides broad-spectrum protection mostly in the UVB and UVAII range, with some protection in the UVAI range.
While its UVA protection isnāt as strong as zinc oxideās, the difference is minor.
A common myth is that mineral UV filters reflect UV light. However, modern research shows titanium dioxide absorbs UV radiation like chemical filters (~95% absorption & 5% reflection).
Thanks to its non-irritating nature, titanium dioxide is suitable for sensitive, acne-prone, or redness-prone skin. It is unlikely to cause "eye sting" like other sunscreen ingredients.
A major drawback of this ingredient is its white cast and thick texture. This is why mineral sunscreens often leave a white cast and are less cosmetically elegant than chemical/hybrid sunscreens.
To improve white cast and spreadability, micronized or nano-sized titanium dioxide is often used.
There are ongoing concerns surrounding nano-titanium oxide's impact on marine ecosystems.
There is no conclusive evidence that any form of titanium oxide (or any other sunscreen ingredients) will cause harm to marine ecosystems or coral reefs. The science is still developing but many consumers are keeping a close eye on this issue.
Please note, many destinations have reef-safety sunscreen rules. For instance, the U.S. Virgin Islands advises all visitors to use non-nano mineral sunscreens.
Nano mineral sunscreens once raised safety concerns about absorption into skin.
Extensive research has shown that they do not penetrate healthy or damaged skin; they remain safely on the surface and the top layer of dead skin (stratum corneum).
You'll likely find titanium dioxide bundled with alumina, silica, or dimethicone. These ingredients help make titanium dioxide highly photostable; this prevents it from interacting with other formula components under UV light.
Learn more about Titanium DioxideSynthetic Fluorphlogopite is the synthethic version of mica. It consists of fluorine, aluminum and silicate.
Synthetic Fluorphlogopite is used to add volume to products.
It is considered non-irritating on the skin.
Learn more about Synthetic FluorphlogopiteTin Oxide is an inorganic oxide used to add opacity and volume to a product. In nature, it is already found in mineral form. The main ore of tin is an opaque and shiny mineral called casseterite.
Tin Oxide helps remove translucency in a product, or make it more opaque. Besides adding opacity, tin oxide is used for bulking to add volume.
Ci 77492 is also hydrated iron III oxide. It's sole purpose is to give a yellow hue to products.
Iron III oxides are classified as inorganic chemicals for coloring.
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.
Learn more about CI 77492Ci 75470 is a bright-red pigment. It is AKA carmine.
Carmine is derived from insects such as the cochineal beetle. This ingredient has been used as a natural dye for over 2000 years.
This ingredient is used to impart a blue color. It is not water-soluble.
It goes by two different names:
1. Ferric Ferrocyanide: a synthetic dark blue pigment
2. Ferric Ammonium Ferrocyanide: a synthetic blue pigment, also called Prussian blue
In the EU, both of these colors must be labeled as 'CI 77510'.
Learn more about CI 77510Ci 77491 is also hydrated iron III oxide. It's sole purpose is to give a red/pink hue to products.
Iron III oxides are classified as inorganic chemicals for coloring.
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.
Learn more about CI 77491Triethoxycaprylylsilane is a silicone used to bind and stabilize ingredients.
As an emulsifier, it helps prevent ingredients from separating. This can help elongate the shelf life of products.
Triethoxycaprylylsilane is often used to coat mineral sunscreens ingredients to help give a better feel. It also helps reduce oxidative stress in sunscreens.
