Hydrogenated polydecene (HP) is the collective name of a group of multifaceted emollients (PolyAlphaOlefins) derived from a polydecene hydrogenation process. The level of hydrogenation impacts the properties of the resulting compounds, so there are numerous ingredients INCI marked as hydrogenated polydecene, which have different sensory profiles, dispersion ability, and spreadability.
Pure and completely safe, the HPs are oily, inescapable cosmetic ingredients suitable for all skin types, specifically sensitive ones. Formulations with these chemically inert compounds will enjoy silky and velvety sensations. Excellent wetting capabilities of Hydrogenated polydecene are ideal for suncare and make-up applications and completely innocuousness - ideal for babies and sensitive skins. Extraordinary pigment dispersion properties provide improved color uniformity and spreadability for cosmetics.
HPs are unique classes of ingredients that can be a good alternative for silicones, mineral oils, petrolatum, and polybutene, providing brighter, clearer, and non-comedogenic final products with lesser irritating potential and high stability in a wide range of pH systems.
Safety
In vivo tests with 22 volunteers with atopic and dry skin who were applied Hydrogenated polydecene twice daily for 28 days showed no intolerance or irritation and a positive effect on dryness, scaling, and roughness.Dermal penetration of HP showed no percutaneous absorption deeper than the external skin layer.
Ingredient products
There is a wide range of hydrogenated polydecenes with different viscosities and feels. They can offer exciting possibilities for cosmetic formulations with attributes such as softness, emollience, moisturizing, non-occlusivity, and lubricity without greasiness. The fully hydrogenated polydecenes are inert and safe; they do not irritate even the most sensitive skin.
The branched molecule of hydrogenated polydecene enables excellent spreadability and pigment-wetting capacity. As such, it is ideal for sun care and color care applications. It is a colorless and odorless ingredient suitable for lipsticks and lip glosses. As a non-sensitizing ingredient, it can be used for baby and mother care products, even in the nipple areas of breastfeeding mothers.
Hydrogenated polydecene offers sophisticated textures in most cosmetic applications. A silky, non-greasy feel with good spreadability and dry out compares this ingredient to Vegetable Squalene or Cyclomethicone C6.
Photostable Hydrogenated polydecenes are compatible with most cosmetic ingredients. They are inert and will not react in a comprehensive pH range. They are soluble in most non-polar solvents. They are generally compatible with ethers, esters, fatty alcohols, saturated and unsaturated triglycerides, mineral hydrocarbons, and cyclomethicones but not with silicon oils. Hydrogenated polydecenes can replace photo-reactive esters or mineral oils containing many unwanted compounds.Due to the characteristic kinematic viscosity, Hydrogenated polydecenes offer a constant behavior in both hot and cold processes. Friction coefficient testing shows superior lubricating properties even at very low temperatures.
Hydrogenated polydecenes are versatile ingredients used in skin, color, sun, and hair care applications. They are safe lipid phases for emulsions and lotions and excellent pigment dispersers in foundations, lipsticks, and suncare products. They offer binder properties in pressed powers, conditioning in hair care, and slip-in massage products. They have no odor so that they can be used in aromatherapy, hypoallergenics, and baby products.
What are the benefits of Hydrogenated Polydecene?
Ingredients marked as Hydrogenated Polydecene are extremely stable to oxidation, thermal attack, and pH extremes. In addition, these colorless, odorless, and non-comedogenic PAO products provide a broad range of skin-feel properties.
This line of ingredients may fill today's personal care market needs by providing several potential attributes in personal care applications:
- Provide a broad range of spreadability values that may be used to customize skin feel.
- Stable over a broad pH range for the easy formulation of acidic alpha- and beta-hydroxy acids containing creams as well as very high pH hair relaxers.
- Compatible with a wide range of personal care ingredients, including certain sunscreen active ingredients and silicones.
- It can be readily incorporated into a broad range of skin and hair care formulations.
