Carrier Oils and Dilution Flashcards

Which carrier oil has the highest oleic acid content and is known for its exceptional skin penetration and moisturizing properties?

Answer: Olive oil

Olive oil has a very high oleic acid content (55–83%) which contributes to its deep moisturizing and skin-softening properties.

Jojoba 'oil' is technically classified as which type of substance?

Answer: A liquid wax

Jojoba is technically a liquid wax ester, not an oil, making it extremely shelf-stable and resistant to rancidity.

Which carrier oil is cold-pressed from grape seeds and is known for its light texture and high linoleic acid content?

Answer: Grapeseed oil

Grapeseed oil is light, non-greasy, rich in linoleic acid, and is a popular choice for massage and blending due to its neutral scent.

What is the primary concern when using a carrier oil with a short shelf life, such as rosehip seed oil?

Answer: Rancidity, which can irritate skin and degrade essential oil quality

Carrier oils high in polyunsaturated fatty acids like rosehip oxidize quickly, leading to rancidity that can irritate skin.

Which carrier oil, derived from a nut, is particularly recommended for dry, mature, and sensitive skin types due to its emollient properties?

Answer: Sweet almond oil

Sweet almond oil is rich in oleic and linoleic acids, making it highly emollient and gentle enough for sensitive and mature skin.

Fractionated coconut oil differs from regular coconut oil primarily because it:

Answer: Remains liquid at room temperature and has an extended shelf life

Fractionation removes long-chain fatty acids from coconut oil, leaving medium-chain triglycerides that stay liquid and resist rancidity.
