I agree with you. I would disregard the solid (salt/sugar) portion and

preserve the oil.

Jenn,

Preservatives are always used and percentages are always based on the total

of the formula. In other words you will have 1% preservative and 99% other

ingredients. This is regardless of what those other ingredients may be.

Hope this helps clarify this dilemma for you.

please help - usage of Phenonip...

Hello all! I'm in the process of designing a sugar/salt scrub

recipe and have everything including the Phenonip. I know that

the Phenonip is to be used at a maximum of 1%. My question: is

it to be used at 1% of the OILS in the recipe (or the liquid portion)

or at 1% of the final product (Oils and Salts). It seems to me that

it would be 1% of the oils, as the salt/sugar would be akin to

solid beads in an oily mixture as they only add mass and do not

contribute to the liquid portion. I've totally confused myself! I've

looked in the archives and cannot find the answer. Can anyone

help me with this?

Also, I've heard conflicting data regarding sugar in scrubs

causing infections. I feel this is nonsense, but to be on the safe

side I would like to ask you all.

Thanks so much, this is such a valuable forum

Thank you Maurice and for answering my question. You both gave

me opposite answers, so I'm still a little confused. Sorry.

, I understand what you are saying, about using 1% Phenonip and

99% everything else. That makes sense to me in most cases, but in

this case where the Phenonip concentration will be much higher in the

liquid portion of the scrub due to the bulk of the scrub

being " insoluble " for the most part - then I don't understand. The

oil portion is really what stays on the skin, not the salt, so I

worry that the concentration may be too high. I just want to make

sure that having a concentration higher than 1% in the liquid phase

will be safe.

I apologize if this question seems ignorant - I know I have a lot to

learn still.

Thank you for your help,

Jenn D

You noticed.

,

You are correct. Intuitively, that's what I thought also. But if you

consider the product parameters in Jenn's message, we are dealing with

a mixture, not a solution, of salt and oil.

Assuming you keep the Phenonip at 1%, as you increase the amount of

Salt, you must, therefore, decrease the amount of Oil.

If we look at the extreme cases:

When we have 99% Oil, 1% Phenonip and 0% Salt, then we have 99% Oil,

and 1% Phenonip

And when we have 0% Oil, 1% Phenonip and 99% Salt, then we have 0% Oil,

and 100% Phenonip

I have no idea what percent Oil is in Jenn's formula, but if we assume

that the percentage of Oil is between 44% and 24%, then we have the

following relationships:

44% Oil, 1% Phenonip and 55% Salt, then we have 97.8% Oil, and 2.2%

Phenonip

39% Oil, 1% Phenonip and 60% Salt, then we have 97.5% Oil, and 2.5%

Phenonip

34% Oil, 1% Phenonip and 65% Salt, then we have 97.1% Oil, and 2.9%

Phenonip

29% Oil, 1% Phenonip and 70% Salt, then we have 96.7% Oil, and 3.3%

Phenonip

24% Oil, 1% Phenonip and 75% Salt, then we have 96% Oil, and 4%

Phenonip

I don't believe exceeding a level of 1% Phenonip in the Oil is

warranted.
