CCAP Blending and Formulation Flashcards

In a clinical aromatherapy context, 'base notes' in a blend serve primarily to:

Answer: Slow the overall evaporation rate and anchor the blend

Base notes have heavy, large molecules that evaporate slowly and act as fixatives, prolonging the overall aromatic presence of a blend on skin.

A CCAP practitioner is formulating a respiratory support inhaler for a hospitalized patient. The MOST appropriate method of application is:

Answer: Personal nasal inhaler stick with 15–20 drops of essential oil blend

A personal nasal inhaler stick delivers targeted inhalation therapy safely without exposing other patients or staff to the aroma in shared clinical spaces.

Which carrier oil is MOST appropriate for a client requiring rapid skin absorption for a clinical massage treatment?

Answer: Sweet almond oil

Sweet almond oil has a light texture, medium absorption rate, and is well-tolerated by most skin types, making it one of the most versatile clinical massage carriers.

When preparing an aromatherapy blend for a client with a known nut allergy, which carrier oil should be AVOIDED?

Answer: Sweet almond oil

Sweet almond oil is derived from almonds (tree nuts) and poses a potential allergic risk for clients with tree nut allergies — jojoba or grapeseed are safer alternatives.

In clinical aromatherapy formulation, what is the purpose of using anhydrous emulsifiers like polysorbate 20 when creating a water-based product?

Answer: To properly disperse oil-soluble essential oils into aqueous products

Emulsifiers like polysorbate 20 allow oil-soluble essential oils to disperse evenly in water-based formulations, preventing separation and ensuring uniform dosing.

What is the recommended maximum percentage of essential oils in a blend intended for direct inhalation from a steam bowl?

Answer: 1–3 drops per bowl of hot water

Steam inhalation uses 1–3 drops in a bowl of hot water; more than this creates mucous membrane irritation from highly concentrated volatile constituents.
