CCAP Blending and Formulation Flashcards

In aromatherapy, a 'top note' essential oil is best characterized by:

Answer: A light, fresh scent that evaporates quickly within 30–60 minutes

Top notes evaporate fastest due to small, volatile molecules and provide the initial impression of a blend, typically lasting 30–60 minutes.

Which of the following carrier oils is BEST suited for a client with acne-prone or oily skin?

Answer: Jojoba oil

Jojoba is technically a liquid wax that closely mimics skin sebum, is non-comedogenic, and is ideal for oily or acne-prone skin without clogging pores.

A standard safe dilution for a full-body massage blend intended for a healthy adult is:

Answer: 1–3%

A 1–3% dilution is the generally accepted safe range for full-body application on healthy adults, reducing sensitization risk while maintaining therapeutic efficacy.

When blending essential oils for an elderly client with sensitive skin, the dilution rate should be:

Answer: Lower than for a healthy adult (0.5–1%)

Elderly clients often have thinner, more permeable skin and reduced detoxification capacity, so lower dilutions (0.5–1%) minimize sensitization and systemic overload.

What is the primary clinical purpose of using a synergy blend versus a single essential oil?

Answer: To achieve combined or enhanced therapeutic effects through constituent interactions

Synergy blends are designed so that the combination of multiple essential oils produces an additive or synergistic therapeutic effect greater than any single oil alone.

Which of the following is the correct procedure before applying a new essential oil blend to a client for the first time?

Answer: Conduct a patch test on the inner forearm and wait 24–48 hours

A patch test on a small skin area, left for 24–48 hours, is the standard procedure to screen for contact sensitization before full application of a new blend.
