Home Cosmetic Science Talk Formulating Phenethyl alcohol

  • Phenethyl alcohol

    I haven’t used phenethyl alcohol. In the forum experts said it smell like rose. 

    My question is can it function as fragrance cosmetic products like cream and lotion? 

    If yes then at what percentage?

    What percentage of phenethyl alcohol will be enough to smell as strong as 0.1% rose fragrance oil in lotion and cream?

    It does smell of roses…however I don’t believe it would make a cost effective fragrance.  I use it as PART of preservative package (head-space), and use it at I believe .35%.  This does NOT carry into the final product, as far as I can tell.

    If you look at a GCMS of rose absolute…it is not uncommon for it to be 50% PHENYLETHYL ALCOHOL

    So….when you smell a rose…you are smelling…phenylethyl alcohol.

    @Graillotion thanks for input. 
    As it work as preservative booster too and i can remove the word fragrance from LoI but still have a beautiful fragrance, a bit extra cost will be ok.

    As i will import it from another country, i wanted to have an estimation that what percentage of it will have about the same smell as 0.1% fragrance oil so i can calculate the in use cost better.

    Have you used it in an emulsion without fragrance oil?

    I use some form of fragrance (EO or FO) in everything, so I guess what I should have said….was at .35% it was completely masked by my fragrance at .5%.

    Therefore I can not help in estimating at what level it would serve as a fragrance.

    @Graillotion What do you mean by this sentence?

    That means….at .35% inclusion rate, I do not smell rose.

    Aahhaa 
    So it will increase the cost a lot because fragrance oil at 0.1% is enough for emulsion smell. 

    Thanks a lot

    Phenethyl alcohol can migrate in to packaging and implements so be sure to get stability data with complete packaged product.

    @PhilGeis which type of plastic does it migrate more? HDPE or PET?

    I don’t have that specific in formation.  My experience has been with a few finished products - the stuff is not so commonly used.

    @Abdullah:

    I use Phenethyl Alcohol quite a bit.  At best, you will get a faint Rose scent to any product that contains it.  Sensitive noses will pick up the scent, but generally most people will not identify it.  If you want to use it, it could function as a dual-purpose Preservative ingredient and “Rose scent booster”, but will not fragrance a product on its own.

    If you pair it with a Rose Hydrosol, that would work.

    Agreed…rose fragrance booster is a good term.  In my face cream I use 3% rose absolute, and I believe the small amount of P alcohol enhances that scent.

    I package that product is glass…so no issues.

    @MarkBroussard that is good to know. 
    As rose absolute as 50% phenethyl alcohol and in my emulsions 0.1% rose FO is enough to fragrance the product i thought 0.2-0.3% phenethyl alcohol would have the same fragrance powder with extra preservative boosting.

    @Abdullah

    The issue is that Rose FO is comprised of numerous constituents that have different rates of evaporation … in fragrance parlance “notes” … Top, Middle, Base.  Phenethyl Alcohol is a pure compound, so it only has one note and will not have the same intensity or linger as long as a Rose FO with all three note components.

    I use 0.3% and, often, no other fragrance ingredients and yes the smell absolutely comes through.
