Lemon Scented Tea Tree

 

Typical Composition

 

Chemically the oil is characterised by 50% or higher amounts of

citral and around 20% citronellal. The total aldehyde content can go

as high as 90%.

 

Compound Percentage

 

6 me 5 hepten 2 one 1%

linalool 2%

iso pulegol 3%

citronellal 12%

<iso> iso pulegol 1%

cis iso citral 2%

trans iso citral 2%

citronellol 2%

neral 27%

geraniol 3%

geranial 34%

bicyclogermacrene 2%

 

The citronellal has a positive rotation of +10degrees and 20degrees

C, but the lower rotating oils are desired as the citral (geranial

and neral) content should be higher.

 

Uses:

* Can be used as a fragrance raw material. The odour has been

described as a strong pleasant lemon odour with a delightful fresh

rosy tone which is particularly peresistent on dry-down. In 1929

the " Perfumery and Essential Oil Record " suggested its use as a base

for citrus compositions or as a toner and modifier of Rose

Compositions. It was suggested to be an ideal replacement for the

more expensive Verbena oil (1).

* As a natural instect repellant. A 20% solution was found to be

effective against Anopheles farauti. It gave an immediate repellancy

and remained effefctive for 4 hours for at least 50% of the insects.

This is good results for an essential oil (2).

* To improve the odour of Tea Tree Oil, melaleuca alternifolia.

Around 5% can be added to give a noticable improvement in the odour.

When up to 20% is added the is an increased activity against

Staphylococcus aureus when compared with the pure Tea Tree Oil (3).

* As a cosmetic preservative/ It has been shown to be effective as a

preservative in shampoos at 1%

* As an active in natural anti-microbial or as an active in deodorant

products.

* Lemon Scented Tea Tree has been shown to be active against

Aspergillus niger, Vandida albicans and Staphylococus aures. Minimum

Inhibatory Concentration (MIC) values have been recorded as follows

(4):

Aspergillus niger 0.36% w/w

Pseudomonas aeruginosa >2.38% w/w

Candida albicans 0.21% w/w

Staphylococcus aureus 0.08% w/w

 

One small advantage is Lemon Scented Tea Tree is already registered

with ENEICS
