One more question for Butch

[Guest guest]

I saw an old post you commented on and I can't remember what the

origianl post was about to find your reply BUT this is something I've

wondered about and you touched upon it in that post:

 

When blending oils together is it possible to blend oils that share

much of the same chemical makeup thereby exposing yourself to too much

of a particular chemical? I don't know if I'm expressing my thoughts

right here-it's not about " blending " as in for scent or to gain a

certain therapeutic effect but blending oils together for whatever

purpose that may somehow expose the user to too much of a chemical

whose exposure should perhaps be limited? Perhaps this isn't even an

issue with eo's but since these are chemicals we are working with it's

something I've wondered about. I remember your comment had something

to do with this and I wish I could remember to post as a reference.

Thanks, Susan

As I am on the list tonight, thought i would save Butch from replying

to this one. By blending different oils you can easily go over the top

with a given chemical as far as safety is concerned. The formula you

gave is a good example where by blending several citrus peel oils you

can get a big hit of d-limonene.

 

To do safety assesment on formulas you need a working knowledge of the

basic chemical constituents of the oils you are using, plus the ability

to do some pretty complicated arithmetic.

 

I may be wrong here, but to me it looks like you are trying to get

information off this newsgroup on stuff that you should be taking a

course on. Much of the kind of exact data you need is not to be found

on the internet, but is in expensive specialist books and journals.

Hence the reason it is not free. Cosmetic chemistry and perfumery

courses in the UK, for example, are run out of Universities. My friend

Wanda Sellar took one on this subject and it took a lot of dedicated

work over some period of time. Does not mean people can't play around

as I said earlier, but to do it safely you need proper documentary

knowledge.

I have absolutely looked into a cosmetic chemistry course but they are

not offered individually, at least not that I have found, but only as

part of a degree program-a degree which I am not interested in

obtaining. I would truly prefer something in the natural

healing/natural beauty products field and am taking a course beginning

this month at a local college. My question came up because I so often

see people post a question, as I did, about a product with a certain

number of eo's in them or links to sites with lotions, creams, etc

with many eo's as part of the ingredients. I see so many sellers on

line and in health food stores selling personal care products loaded

with eo's. Then I see your posts and Butch's posts talking about the

need for safety and I wonder how many of these sellers have any

knowledge of chemistry and wonder can the products be safe. I also

think that if I wish to try making soaps, etc that I don't even want

to attempt it until I understand what I'm putting in them. That's

what lead me here to begin with-the desire to stop using products

loaded with chemicals I have no understanding of and try to use/make

something with less ingredients that can still be effective and

enjoyable. By the way, if I choose to take courses is there a way to

tell who is teaching the real stuff? On the down side, you and Butch

do such a great job pushing safety and looking out for the quacks, it

has made me very skeptical before I've even begun trying to learn

something! Susan

It's another day and I was giving your question and my answer some more

thought. As I have said many times on this group, people must never

ever rely on what internet sellers of products claim for them. There

are now tens of thousands of such web sites with I reckon 95 percent

knowing very little about what they sell. That is why I keep plugging

away at people that they cannot live by the " sound bite " philosophy

when dealing with health issues or product safety.

 

These newsgroups and others are crammed with people who come

across as knowledgable yet they have had no training of any kind in

what they talk about. That particularly applies to the majority of

those selling essential oils and so called 'natural perfumes'. The old

hands on this group know them well.

 

Safety when dealing with individual oils is fairly simple if you have

got the basic information. Assessment of blends is another ballgame as

it does require a good knowledge of essential oil chemistry. That is

why I never give a straight answer as far as formulas are concerned,

otherwise all and sundry would be expecting very time consuming answers

to such questions and without any payment for my time.

 

I hope that is a little clearer than what I said last night when I was

about to hit the sack.
