Air freshener Based on 99 % isopropyl alcohol and fragrance oil only !
I am trying to develop my Air Freshener which was contains
- 10 % fragrance oil
- 10 % tween 20
- preservative
- 20 % isopropyl alcoholafter problems in Solubility and separation and trying many emulsifiers and not good Stabilities and masking or weakness of the fragrance . Besides foam forming with filling by the machine. and make the floor wet after spraying by the normal trigger spray !!!!
i am thinking ???? to replace the formula by :
- 99% isopropyl alcohol
- fragrance oilWhat is your opinion , what you think ?
rather than the Cost !? -

@bahey I assume the rest of your formula is mainly water, rigth? If that’s the case, I’d prefer to increase the level of your alcohol rather than to increase the solubilizer. Increasing alcohol will let fragrance bloom, while increasing the solubilizer in a water-based system will make some of the fragrance be solubilized and not available for performing properly.

That’s which i meant .
I had increased solubilizer and it masks the fragrance. So i am thinking do add only alcohol and fragrance and increase the price -
hi there
For a normal Air Freshener, 10 % Perfum is way too much. if scent sensation is not good enough with lower concentrations you should find a better spray nozzle that distributes the product finer to the air so that it will not separate so fast from the air (Aptar has something in the portfolio for that). normally I would say perfume for an air Freshener is between 1-3 % more is a lot.
pure Isopropyl is possible but not necessary if you dissolve your perfume in isopropyl alcohol you can start adding water in small portions until it gets foggy. then choose 5 % less water and you will be mostly fine and still able to add some water, which is more Price-efficient.
although you may encounter issues with labeling if you use that big amount of Iso you will be flammable and you need to label that which can be difficult because there is much non-flammable Air Freshener in the market at least as long as you are not in an Aerosol can.
hope that helps

Is there a reason you are not using ethanol?. You won’t be able to mask the pungent IPA odor, no matter how much fragrance you use.
If ethanol is not an option ask your suppliers for a low foam tensioactive. A water soluble defoamer would be easy to get and incorporate at low cost. -

Really helps me alot ,
Many Thanks for your very valuable suggestions Dear ,the main reason of this option is the availability of ISO in my country plus no any separation probabilities.
and for uses i found that the floor doesn’t get wet with normal formulas based on water , doesn’t stain the clothes and carpets .
and I suggest the we can use less perfumes concentration.i am still trying
thanks again -
@bahey first I go with @DAS why using ipa I guess ethanol is much better, then I will not go with @ketchito for his choice because according to my experience in such level 10% of fragrance you did not need some ingredient that bloom you fragrance so for you case I will just using peg 40 it will almost solve your problem.
-
Hello, I know this is an older thread but I just happened upon it. I saw your comment about using peg 40 or hydrogenated castor oil in the room freshener to help with the fragrance.
I have never seen this used before. Could you please explain the logic and effectiveness? I’m curious as to how and why this works. Thank you!

@Fekher Solubilizers trap oils (like the ones in fragrances), so the more solubilizer you add, the more fragrance will be trapped in it (due to their partition coefficient), not letting the fragrance completely bloom upon aplication.
When you use a mixture of water and high quantities of alcohol (like perfumes do), you let your media generate enough solvency so fragrance ingredients are solvated rather than solubilized.

Just jumping onto this old thread.
Is there a need to add water at all? Could I just use alcohol?
The reason I ask is for shelf life. I’m looking at adding a preservative since I’ve been making one with a higher amount of water in it. But the preservative apparently lasts 12-18 months. I wonder if I could get a longer shelf life by just using alcohol, and how that would affect the room spray?

Wich is the best formulation for air freshener liquid according to your experiences. Please share the knowledge to make a genius product.

Hello. I make a room freshener. I do use alcohol. Isopropyl… Because I have not tried ethanol yet. Can easily be remedied with Everclear or another pure alcohol from the liquor store that is at least 190 proof.
N
ot sure what you said your preservative is, but as long as you have at least 20% alcohol (100% alcohol) in your product it will act as the preservative.
If a solublizer inhibits your fragrance, you could omit it and “shake vigorously prior to use”.
I personally would not omit water all together… The alcohol preserves and assists in evaporation so surfaces do not get wet.
Someone in this thread suggested Hydrogenated Castor oil. I am interested in the logic and effectiveness of this.
Also, for best fragrance results, be sure to use a combination of notes in your Essential oils. High, Medium, and Low. This really helps with staying power.
And…. Instead of water, use HYDROSOL! Or floral water.
I also make room fresheners that are NOT liquid. Let me know if you are interested. I would happily share my formula.

Thank you for sharing your experience with us, i’m going to make one~

Would you be able to share the formula with me?

neither needs a preservative
