| Why do we use it in formulations? | Isododecane is incredibly useful in liquid cosmetics - We’d call it indispensable. It is an excellent choice for liquifying cosmetics that we need to set quickly (liquid lipstick, liquid eyeliner, etc.) as it sets quickly but spreads beautifully before setting. It is also an excellent solvent for strong film-forming silicone resins like trimethylsiloxysilicate. |
| Do you need it? | If you want to make liquid cosmetics it is necessary. |
| Strengths | Fantastic fast-evaporating emollient. |
| Alternatives & Substitutions | Nothing, really. Cyclomethicone is also slippy and volatile, but doesn’t have the same dry-touch finish as isododecane and that finish can be absolutely instrumental to the performance of cosmetics like liquid lipsticks and eyeshadow primers. |
| Tips, Tricks, and Quirks |
Its weightless feel and fast evaporation speed make it an excellent addition to many products where we want great spreadability but no residual weight - think cosmetics and hair products. Isododecane is a great solvent, which makes it fantastic for cleaning up hard-to-clean messes! We find it brilliant for cleaning up stubborn smudges of colorful cosmetics. |
