Apply aromatic plant oil chemistry to beauty treatments

Assessment tool

Version 1.0
Issue Date: March 2024


This unit applies to beauty therapists in facial, body, hand or foot massage treatments, exercising judgement in planning and selecting appropriate products, services, equipment and techniques.

This unit describes the performance outcomes, skills and knowledge required to identify and apply aromatic plant oil chemistry to the blending of preparations for use in beauty treatments.

In order to select and blend aromatic plant oils for aromatic face and body treatments the therapist is required to develop a thorough knowledge of their characteristics. This unit describes the process of identifying the properties, origins and therapeutic profiles of a limited range of aromatic plant oils and carrier oils that may be selected and blended.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the following is essential:

applying common names, botanical names and plant family of twelve selected aromatic plant oils

applying properties and profiles of minimum of twelve aromatic plant oils

applying organic chemistry in selecting and preparing aromatic plant oils for use in range of beauty treatments

applying knowledge of properties of carrier oils and additives

applying knowledge of appropriate ratios of aromatic plant oils to carrier oils, additives and other mediums for use in a range of beauty treatments

applying safe work practices when storing and handling ingredients

accurately and legibly recording relevant data.

Context of and specific resources for assessment

Assessment must ensure:

that competency is consistently demonstrated over a period of time and observed by the assessor or the technical expert working in partnership with the assessor as described in the Assessment Guidelines

that competency is demonstrated in the workplace or a simulated workplace environment in a range of real work situations which may include client interruptions and involvement in other related activities normally expected in the workplace.

Assessment must ensure access to:

an environment, which includes as a minimum:

aromatic plant oils preparation and storage area

range of aromatic plant oils, carrier oils and additives

text and online information relating to application of aromatic plant oils in beauty treatments

product information and safety data on range of aromatic plant oils, carrier oils and additives

a range of clients with different aromatherapy treatment requirements.

For further guidance on the use of an appropriate simulated environment, refer to the Assessment Guidelines in this Training Package.

Methods of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

observation of learner performing a range of tasks in the workplace or a simulated work environment, over sufficient time to demonstrate handling of a range of contingencies, including:

evaluating carbon backbone and functional groups of selected aromatic oils

identifying proportions of carrier oils and additives for aromatic plant oil blends for use in beauty treatments

consistent application of workplace policies and procedures and safe work practices when storing and handling ingredients

case studies, written and oral questioning or interview to test knowledge of such things as:

common names, botanical names and plant family of twelve selected aromatic plant oils

properties and profiles of a minimum of twelve aromatic plant oils

application of organic chemistry in selection and preparation of aromatic plant oils for use in a range of beauty treatments

properties of carrier oils and additives

appropriate ratios of aromatic plant oils to carrier oils, additives and other mediums for use in a range of beauty treatments

uses of aromatic plant oils

completion of workplace documentation relevant to applying aromatic plant oil chemistry to beauty treatments

third-party reports from technical experts

completion of self-paced learning materials, including personal reflection and feedback from a trainer, workplace coach or supervisor.

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

SIBBBOS505A Blend and apply a range of aromatic plant oils for beauty treatments

SIBBCCS407A Interpret the chemical composition and physical actions of cosmetic products.
