Stability
Methylbutenes are highly volatile liquids and are known to polymerize upon extended storage. They are also classified as highly flammable.
Safety
Safety Profile
Primarily identified as chemical intermediates and industrial solvents, methylbutenes are not commonly recognized as active skincare ingredients. Dermal toxicity is currently 'not determined'. Specific isomers, such as 2-Methyl-2-butene, have been described as 'mildly toxic' and possess a 'disagreeable odor'. The EPA lists 'METHYLBUTENE (MIXED ISOMERS)' with an 'Approved' FDA status; however, this refers to its general substance classification, not a specific cosmetic safety assessment. The Cosmetic Ingredient Database (CosIng) categorizes methylbutenes solely as a solvent.

Verdict
Due to its primary classification as an industrial chemical intermediate, undetermined dermal toxicity, flammability, volatility, and potential mild toxicity for some isomers, methylbutenes are not suitable for precision skincare formulations.
