Hydrogenated Poly(C6-14 Olefin) is a high-purity synthetic hydrocarbon that functions as a non-greasy emollient and skin-conditioning agent. This ingredient provides a silky, smooth texture to formulations and serves as an effective alternative to Squalane or Mineral Oil due to its superior stability and skin-feel.

- Primary Benefits: Exceptional emollience, prevents trans-epidermal water loss (TEWL), provides a luxurious slip without greasiness, and enhances the spreadability of sunscreens and heavy creams.
- Potential Risks: Generally considered inert and non-reactive, though excessive use in very oily skin types may feel slightly occlusive for some individuals.
Biological Action & Cosmetic Profile
Chemically classified as a branched-chain aliphatic hydrocarbon, this polymer consists of saturated carbon chains. Its primary biological function is the reinforcement of the skin’s lipid barrier. By filling the gaps between desquamating corneocytes, it smooths the skin surface and prevents the evaporation of moisture from the deeper dermal layers. Unlike many natural botanical oils, this synthetic hydrocarbon lacks double bonds, making it highly resistant to oxidation and rancidity when exposed to light and air.The sensory profile of this ingredient is characterized by a “velvety” feel. It is frequently utilized in high-end formulations to mimic the biological compatibility of human sebum. In color cosmetics and sun protection products, it serves as an excellent pigment dispersant, ensuring that active ingredients like Titanium Dioxide or Zinc Oxide are distributed evenly across the skin without clumping or streaking.Formulators value this ingredient for its ability to modify the viscosity of oil-based phases. It can replace Isododecane or Isohexadecane when a more substantive, long-lasting emollience is required. Because it is chemically inert, it does not interfere with the activity of sensitive molecules like Retinol or Ascorbic Acid.
Routine Integration
- Synergies: Works exceptionally well with humectants like Glycerin or Sodium Hyaluronate by “locking in” the water they attract. It also pairs effectively with Ceramide Np and Cholesterol to mimic the natural skin barrier.
Clinical Consensus & Safety
The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated the safety of hydrogenated polyolefins several times, most recently in 2019. The panel concluded that Hydrogenated Poly(C6-14 Olefin) is safe for use in cosmetics in the present practices of use and concentration. Clinical tests indicate it is non-sensitizing, non-irritating, and non-phototoxic. Because of its high molecular weight and lack of reactivity, it does not penetrate the skin barrier into the bloodstream, making it a preferred choice for sensitive skin formulations.
Is Hydrogenated Poly(C6-14 Olefin) the same as mineral oil?
No. While both are hydrocarbons, Hydrogenated Poly(C6-14 Olefin) is a fully synthetic polymer designed for a specific molecular weight and purity, whereas Mineral Oil is a complex mixture derived from petroleum refining. This ingredient often provides a lighter, more modern “silicone-like” skin feel compared to traditional mineral oil.
Does this ingredient cause acne or clogged pores?
Current dermatological consensus and comedogenicity testing suggest it is non-comedogenic (rated 0-1). It stays on the surface of the skin to provide protection without entering or obstructing the pore lining.
Is it considered a “clean” or “safe” ingredient?
Yes, it is highly regarded for safety in both the EU (CosIng) and the USA. It is often used in hypoallergenic products because it lacks the impurities or allergenic potential found in some natural plant extracts or essential oils.
