What Is Squalane?

Squalane (C₂₃₀H₆₂) is a unique category in cosmetic ingredients — it is technically not an oil at all. It is a fully saturated, branched-chain hydrocarbon containing no fatty acids or glycerol (the defining components of traditional carrier oils). This fundamental structural difference positions squalane as a biomimetic emollient that closely replicates a natural component of human sebum, offering exceptional skin compatibility and a universally well-tolerated feel.

Our squalane is olive-derived, extracted from the unsaponifiable fraction of olive oil (0.5–1.1%) as a sustainable co-product of the food industry. It is COSMOS approved, solvent-free, and represents the premium, plant-based alternative to shark-derived squalane. Because it is 100% saturated with no double bonds, squalane cannot oxidize or go rancid — making it one of the most stable ingredients in cosmetic formulation.

Unique Chemistry: Not a Fatty Acid Oil

Unlike traditional carrier oils (triglycerides composed of glycerol + fatty acids), squalane is a simple hydrocarbon chain consisting only of carbon and hydrogen atoms.

Chemical Formula	C₂₃₀H₆₂ (30 carbons, 62 hydrogens)
Structure Type	Branched-chain saturated hydrocarbon (triterpene derivative)
Molecular Weight	422.81 g/mol
Fatty Acids	None — contains zero oleic, linoleic, palmitic, or any other fatty acids
Glycerol Backbone	None — not a triglyceride; cannot be saponified; saponification value: 0
Saturation	100% saturated — all single bonds; no double bonds; no oxidation sites; cannot go rancid

From Squalene to Squalane

Squalene (with an “e”) naturally comprises ~12% of human sebum but is highly reactive due to 6 double bonds. Squalane (with an “a”) is the hydrogenated, fully saturated version — delivering all the biomimetic benefits without oxidation risk.

Property	Squalene (unstable)	Squalane (stable)
Formula	C₂₃₀H₅₀	C₂₃₀H₆₂
Double Bonds	6 (highly reactive)	0 (chemically inert)
Oxidation Risk	High — forms harmful peroxides	None — no oxidation sites
Shelf Life	Short; degrades rapidly	18+ months, often 5+ years
Cosmetic Use	Not suitable as-is	Premium cosmetic ingredient

Sensory Profile

Skin Benefits

The following describes cosmetic properties based on ingredient research and traditional formulation use — not medical claims.

Biomimetic Hydration — Triple-Action Moisturization

Squalane closely mimics a natural component of human sebum, making it instantly recognized and accepted by skin. Its biomimetic structure provides emollient (softens and smooths skin surface), humectant-like (supports moisture attraction), and mild occlusive (supports moisture retention and helps reduce transepidermal water loss) properties — all in a single, lightweight ingredient.

Barrier Support & Moisture Retention

Squalane is associated with supporting the skin’s natural lipid barrier and reducing transepidermal water loss (TEWL) in cosmetic research. It is naturally present in healthy skin sebum composition, contributing to its exceptional compatibility with barrier-compromised, dry, and sensitive skin.

Support for Mature-Looking Skin

Squalane is commonly used in formulas targeting the appearance of fine lines, loss of elasticity, and dullness in mature-looking skin. Well-hydrated, barrier-supported skin is associated with a more supple, radiant, and youthful appearance. Squalane’s antioxidant-supportive character (from olive-derived natural gamma-tocopherol) contributes to its antioxidant-rich profile.

Calming & Skin Comfort

Squalane is often included in formulas designed to help the skin look and feel calmer, more comfortable, and more settled. Its biomimetic, non-irritating character makes it well-suited for sensitive, reactive, eczema-prone, and post-procedure skin. Hypoallergenic and non-sensitizing.

Sebum-Supportive & Non-Comedogenic

With a comedogenic rating of 0, squalane is completely non-comedogenic. Its sebum-mimicking character supports a more balanced skin environment without adding excess heaviness or contributing to congestion. Well-suited for oily and acne-prone skin that needs hydration without pore-clogging risk.

Antioxidant & Environmental Defense

Olive-derived squalane retains natural gamma-tocopherol from its source, contributing to antioxidant-rich care. Squalane is well-suited for formulas targeting the appearance of dullness and skin stressed by environmental exposure.

Hair, Scalp & Beard Care

Squalane’s lightweight, silky character makes it ideal for hair and scalp care. It conditions without build-up, supports the appearance of enhanced shine and more manageable hair, and is well-tolerated for scalp comfort. Lightweight, non-greasy finish suitable for all hair types.

Frequently Asked Questions

Can squalane clog pores?

No. With a comedogenic rating of 0, squalane is completely non-comedogenic and safe for all skin types, including the most acne-prone skin. Its biomimetic structure is recognized by skin as a natural sebum component.

Is squalane the same as squalene?

No. Squalene (with an “e”) is the unsaturated form with 6 double bonds that naturally occurs in human sebum but oxidizes easily and forms harmful peroxides. Squalane (with an “a”) is the hydrogenated, fully saturated version that is exceptionally stable and cannot oxidize or go rancid.

Is squalane an oil?

Technically, no. Squalane is a pure hydrocarbon (C₂₃₀H₆₂) with no fatty acids or glycerol, so it is not a triglyceride oil. However, it has an oily texture and functions as a luxurious emollient. Products can be labeled “oil-free” while containing squalane.

Can I use squalane if I have oily skin?

Yes. Squalane is well-suited for oily skin because its biomimetic character closely mimics natural sebum, supporting a more balanced, comfortable complexion. It provides essential moisture without contributing to congestion or pore-clogging.

Is squalane good for the appearance of fine lines?

Yes. Squalane is commonly used in formulas targeting the appearance of fine lines, loss of elasticity, and dullness in mature-looking skin. Well-hydrated, barrier-supported skin is associated with a more supple, radiant, and youthful appearance.

What’s the difference between olive-derived and shark-derived squalane?

Chemically, they are identical (C₂₃₀H₆₂). However, olive-derived squalane is sustainable, ethical, plant-based, and COSMOS approved. It is extracted from the unsaponifiable fraction of olive oil as a co-product of the food industry, making it the premium, clean beauty choice.
