How To: Strawberry Glycerine Extract




It's summer and it's strawberry season around these parts of Scandinavia. I've been waiting for the ripest, plumpest, freshest strawberries to be available so I could make this glycerine extract.

And here they are - fresh picked and deliciously aromatic.

Shall we get busy?

Glycerine Extract Ingredients

This is a very simple process and requires only

  • fresh strawberries
  • glycerine
  • preservative 


Water to Glycerine Amounts

Glycerine extracts are commonly made with dried plant materials that are reconstituted with water, then added to the glycerine.

The usual ratio of water-content to glycerine for an extract is 50/50.

For this batch I used

49.8 % Glycerine
49.7 % Strawberry
0,5 % Preservative (I used benzyl alcohol)

Even though fresh strawberry is 'only' about 92% water, I went with a 50/50 ratio of strawberry to glycerine..

Aroma Zone's glycerine extract how-to recommends adding 0,6% broad spectrum preservative, storing the final extract cool, and using within 6 months.

A few of you have asked me about this, and I'll be answering your questions about glycerine as a preservative in an upcoming post.

Meantime, here's a peek at the process of my strawberry glycerine ecxtract.

(those extra strawberries in the bowl in the background? What a shame they wouldn't fit into the jar. We simply had to eat them for dessert)


Method

Making a strawberry glycerine extract is easy peasy.

  • Sterilize the jar and your equipment
  • Slice the strawberry
  • Weigh the strawberry
  • Weigh and add glycerine
  • Add preservative
  • Place lid on jar
  • Keep jar in a dark and not too warm area
  • Agitate the jar daily for 7-10 days

Tip: Always always measure your ingredients by weight - this is the only accurate way to be sure of your amounts in any formula.


When it's Time to Strain

Here's what you need to strain

  • Bottle for your extract
  • Funnel
  • Filter 
  • Receptacle to strain into














As soon as the liquid has run through the filter, transfer the extract to a bottle, put on a label with a date and enjoy your fabulous extract!

What to Use it For

You can use this extract in place of glycerine in any formula. It adds a delicious scent of fresh strawberry. I've been adding it to skin tonic made on a rose hydrosol base, tried it in a light cream, and in a shower gel.

Do Tell

What do you use your glycerine extracts in? Which kinds of extracts have you made - and which are your favorites?

What about a baby spritz? I've just made one, some kind of alcohol-free cologne for a friend of mine who's just given birth, a mix of strawberry, orange and lemon flesh and pineapple.
20% extract to dilute in distilled water and preserve accordingly.
No alcohol, funny scent and lovely for this summer, for boys and girls
Enjoy!

Hey, quick question...where can i find benzyl alcohol?? Ive been looking for it and i havent had any luck! Ive looked on lotion crafter and WSP... could you share with me where to get it, please?


Thank you,

Marie

Hi Marie - I buy mine form a local Danish supplier (Urtegaarden - they are in the links on the sidebar), but if you can find a preservative called Cosgard - this contains beryl alcohol and is broad spectrum as well. You could also use phenonip. Be sure to use at your SUPPLIERS recommended dosage. I hope this helps!

Forgive me -- these autocorrect thingies drive me nuts sometimes.. I wrote BENZYL alcohol above.

Kimberley Jane said...

Do you use your extracts in the heated water phase or in cool down? :)

Lise M Andersen said...

You could go either way - depending on the extract. With strawberry, I'd go with cool down

Marina said...

I tried using this extract in face cream at 5 % in water phase.But it didn't smell strawberries at all so i increased at 30% ( I know it's sounds crazy) I thought it will be very sicky but I actually like it.Do you think it's ok a ding that much in water phase or I shall keep it in cool down at 2%?

Lise M Andersen said...

Hi Marina - It sounds like a lot using 30%, and without knowing the other ingredients in your formula it's hard for me to comment. If you want the full benefit of the scent you might want to add it at cooldown.

Maybe you can use the spritz for young children, but ideally you wouldnt want to use it on infants less than a year old because the is the high risk of development of skin allergies to these fruits.

Hi Marie - many cosmetics ingredients suppliers carry benzyl alcohol ☺

Hi Lise,

1.Glycerites are usually considered as a substitute to avoid alcohol based ingredients right,so i see you have used benzyl alcohol as preservative.Any other alcohol free alternatives to help preserve a glycerite?

2.Is the preservative needs to be added as i read glycerine itself is a preservative?
Kindly guide,as i have just started with glycerites and you have been an inspiration to start with it!

Lise M Andersen said...

Hi Jeevana - Benzyl alcohol is a broad spectrum preservative that is ethanol free-- meaning: benzyl alcohol is alcohol free. You are correct that glycerine is a preservative but needs to be used at a higher dose if it is to function as a stand alone preservative. I am writing a guide about calculating preservatives for glycerites that I hope to finish so on and will offer in my shop as soon as it is published :)
