Description

Overview: Isododecane is a colorless, odorless liquid at ambient temperatures.

Isododecane is a petroleum-derived emollient of 12 carbons in length.

Properties: Melting Point: -81°C (-113.8°F)

Boiling Point: 176 to 192 °C (222.8 to 377.6°F)

Flash Point: 45°C (113°F) closed cup

Auto-Ignition: 410°C (770°F)

Solubility in Water: Slight

Although isododecane is insoluble in water, it is very soluble/miscible with many organic solvents, such as alcohols, ethers, esters, and natural formulation components.

Its low viscosity, density, and relative volatility give skin and body care products good spreadability and smoothness.

Physical Hazards of Isododecane

Isododecane is stable under normal conditions of use. 

Avoid contact with strong oxidizers.

Isododecane is flammable in liquid and vapor form. 

Vapor/gas is heavier than air and may spread along the ground or accumulate in low or confined areas. 

Heating to decomposition may release carbon monoxide, carbon dioxide, and other gases/fumes. 

Avoid heat, open flames, electrostatic discharges, and other potential ignition sources.

Isododecane is an excellent solvent used in various cosmetic and personal care ingredients. 

It has a weightless feel and enhances the spreadability of products. 

Isododecane is considered a solvent and an emollient and will help retain moisture. 

It will also help create a matte finish for lipsticks and foundations.

Isododecane is a synthetic aliphatic hydrocarbon with a branched structure. 

It is a safe, non-irritating, and non-comedogenic cosmetic-grade solvent and emollient with low viscosity, good volatility, spreadability, and drying time. It is a relatively inert, colorless, odorless ingredient suitable for almost all types of skin, hair, sun, and lip care preparations.

Thanks to good solubilizing properties, Isododecane is suitable for cleansing applications which eliminate oil, dirt, and impurities from the skin's surface and effectively remove decorative cosmetics. 

It is compatible and completely soluble with silicones, hydrocarbons, isoparaffin, and mineral spirits.

Isododecane is highly volatile and is usually used in non-residual products. 

It has a low density and low viscosity. 

It can be used as a replacement for oils in emulsions that leave a light non-greasy feeling.

In combination with Isohexadecane or Isoeicosane (which have similar molecular structures), it enables a wide range of skin feel, playtime, and plasticity depending on concentrations and desired results. 

Thanks to high stability, Isododecane is used as an emollient and solid (UV-filter) carrying agent in many sun care applications.

It is a good ingredient for decorative cosmetics including, mascaras, lipsticks, and eyeliners incorporated as a soft emollient, pigment-carrying agent, or plasticizer. 

Isododecane is miscible with silicones, other hydrocarbons, mineral oils, and alcohols. 

In addition, it can be used as a co-solubilizer or co-emulsifier for many non-hydrocarbon materials.

Isododecane is used in mascara, eyeliner, creams, lotions, hair care, conditioners, setting lotions, and hairsprays. It is dermatologically safe and typically used at concentrations of 2-15%.

Formulating Benefits of Isododecane:

Volatile solvent—great for dry-touch or quick-dry formulations, including formulations that work by forming a film (long-wear lipsticks, sunscreens, mascara).

Light Feel.

Non-Greasy.

It has excellent Solvency, which is great for oil cleansers, pigment wetting, active delivery, etc.

Use Levels: 1-100%.

Heat Tolerance: Isododecane can be used in hot process formulations.

Solubility: Oil.

Formulating Ideas: Colour cosmetics, including mascara and lipstick, quick dry skincare, hair oils, cleansing oils, and oil serums with a light touch.

Isododecane has a weightless feel on skin and enhances spreadability of products due to its low viscosity and density.

Isododecane helps prevent evaporation of water from the skin.

Isododecane is an excellent emollient that can be used as replacement to oils in emulsions.

Isododecane is compatible with silicones for imparting shine, slip, and combability for hair care products.

Isododecane conditions hair & skin.

* Silicones are used in many cosmetic applications and have long been considered problematic. 

The cyclic silicone compounds D4 (octamethylcyclotetrasiloxane) and D5 (decamethylcyclopentasiloxane) have been strictly regulated in the EU since 31 January 2020. 

Both cyclosiloxanes are classified as hazardous to water and have been proven non-biodegradable; thus, they accumulate in nature. 

They are also bioaccumulative, meaning that they accumulate in living organisms. 

Other silicone compounds continue to be used in cosmetics, mostly known as cyclomethicones. 

Isododecane, primarily based on renewable raw materials, is an excellent alternative to cyclosiloxanes or silicones.
