Essential Oil Safety Information


Essential oils are very concentrated solutions that have been extracted from plants and it’s our priority to give you a safe way of using them. You can rest assure that each of our products have been safety checked by a substances and mixtures specialist. Each product has potential allergens listed, so you can make an informed decision about using individual products and all our blends comply with EU safety regulations. Following the steps outlined below will ensure that you safely enjoy the benefits that essential oils offer.

Classification, labelling and packaging (CLP)

Classification, labelling and packaging of substances and mixtures (CLP) is the European legislation that requires all retailed substances and mixtures (including essential oil blends) to be safety checked and any have any hazards and/or potential allergens clearly listed on each product. Read More.

We only use 100% natural ingredients and have gone to great lengths to give you complete transparency as to the natural chemicals contained within each blend.

The process of CLP is lengthy and costly, but your safety is our number one priority. We display all CLP information on each product under the heading ‘CLP Safety information’, so you can view this information before making a purchase. This information is also attached to every product.

We also hold Safety data sheets (SDS) for each blend and are available should they required. Please contact or call +44 (0)20 7931 9662 or write to Twoodle Co Ltd, 7 Queen Mary’s Buildings, Stillington Street, London, SW1P 1EF, if you have any questions.

Do not use on your skin and do not take internally or ingest any Twoodle Co essential oil products. If swallowed, seek immediate medical advice or contact a poison centre.

Carcinogenic Essential Oils

Our products do not contain any carcinogenic ingredients. A carcinogenic substance has the potential to damage the human genome at a cellular level. According to Robert Tisserand, author of the book Essential Oil Safety, there has never been any recorded instance of an essential oil causing cancer in humans. However, our customers safety comes first and for this reason, there are several essential oils we do not use as they contain carcinogenic properties.

Personal Safety

Fire Safety: Keep our products away from open flames, heat sources, sparks or hot surfaces.

Skin Safety: All of our products are designed for the purpose of scenting your home and are not for use as a cosmetic. Should any ingredients come into contact with your skin, wash with warm soapy water. If any irritation or inflammation occurs, seek medical advice. If any of our products come into contact with broken skin and a reaction occurs or persistent irritation or inflammation occurs, seek medical advice.

Eye safety: Avoid using any of our products near eyes as some essential oils can cause eye irritation, which could cause lasting damage if not washed. In the event any essential oil product coming into contact with eyes, immediately rinse with cold water for several minutes and seek medical advice if any irritation or inflammation occurs.

Essential Oils – Phototoxicity

As our products are not intended for use on skin, this is for your information only. When skin comes into contact with certain cold pressed citrus essential oils, particularly oils that contain furocoumarins (FCFs), (natural occurring chemicals found in some essential oils), and then exposed to ultraviolet light, phototoxicity (or photosensitisation) can happen. Should any of our products come into contact with your skin, wash the area with warm soapy water immediately. If irritation occurs, seek medical advice. For more information, READ HERE.

The Bergamot essential oil used by us has had the Bergaptene and Furanocoumarins (FCFs) removed and will not cause phototoxicity. Although Grapefruit does also contain FCFs, it contains 24 times less than Lime, Lemon and Bitter Orange.


In the event of a spillage, wipe the affected surface immediately to prevent the essential oil blends from causing damage.


Our products are designed to fully evaporate during use. However, should the need arise to dispose of any essential oil products, they should be disposed of safely and responsibly. Check the product label and contact your local authority for information on how to safely dispose of essential oils.
