What Isopropyl Myristate does

Softens skin and hair
Thins heavy, thick formulas
Helps oil-based ingredients blend

Isopropyl Myristate is made by joining myristic acid, a fatty acid often sourced from coconut or palm kernel oil, with isopropyl alcohol. The result is a clear, light ester with a faint, mild scent.

Formulators reach for it to thin thick ingredients and help creams spread evenly. It also helps other oil-based ingredients blend into a formula. You will often find it in sunscreens, hand creams, hair masks, conditioners and exfoliants, where it leaves skin or hair soft and smooth without a heavy film.

Good for

Suits people who like lightweight lotions, creams and hair products that absorb quickly without a heavy coat.

Does Isopropyl Myristate clog pores?

Individual reactions vary. Some people with acne-prone skin prefer to avoid oil-like ingredients, while others use it without trouble. Watch how your skin responds over a couple of weeks, and choose a water-based product if you prefer something lighter.
