detergent’s smell in my shower gel !!
hi, i ve been facing some issues with my shower gel, i don’t know why adding up to 0.8% of the FO to the formula won’t completely mask the “detergent smell” whereas adding only 0.2% of the same Fragrance oils to a hand wash formula is sufficient. Note that they have roughly the same formula, but the shower gel also contains Plantacare 818, Lamesoft po65 and Polyquat 7 (and NaCl since the handwash is water thin)
Any thoughts? TY!!

Perfuming is not an easy science to learn. I started off with making essential oil perfumes which almost everybody across the board did not like. But after a few years of experience I formulated a widely beloved proprietary scent. My friend who was a professional perfumer’s only advice was to experiment. After years of trying to improve my perfuming skills, I agree that experimenting is the simplest and possibly the only practical thing you can do. Scents are so delicate that there’s no way to judge what will work or why its different in different products. Do you by chance have a scent in mind? For instance certain FO’s or EO’s compliment or mask scents. Geranium is an excellent masking scent. Vetiver, benzoin, vanilla, are powerful anchors. If you’re using a premade FO blend, it is often made with strength in mind, basically it’s supposed to work. I’ve only had to use 1% or more FO’s in products with ingredients that are incredibly strong smelling even in small quantities like coco butter.
If you can let me know what scent profile you’re trying to achieve, I might have an idea.

This is excellent advice !!!!

Perfuming wasn’t my thing so I never got good at it.

Hi, thank you for your reply. The issue is not in the FO since it perfectly works for the other product, i was wondering if the 3 ingredients or the salt may have impacted the final smell, are they known for this or not. PS: i use a ready F. oils given to me so i can’t change them. thanks again !!!

Hi,
Some things come to mind:
1. the fragrance gets somehow “trapped” as the addition of NaCl changes the CMC, and a much larger % of fragrance is needed to overcome that;
2. I would do an knock-out experiment in regards to the three added ingredients- one of them might exacerbate the detergent smell in your formula.
3. I’m still learning, so maybe @ketchito can chime in with some real ideas🙂

hi, thank you for your reply. Yes, you are getting closer to the answer i think, because i suspect the Lamesoft (the Glyceryl Oleate part) and i tried to do that screening and proceed by elimination, but it wasn’t able to determine the difference between them .. my nose is saturated ( i make reed diffusers and body splash at the same time xD)

Hopefully after a walk (fresh air) your nose will “perform” better🙂
It’s always good to learn new things, so is it too much if I ask you to share the “culprit” after you finish your experiments?
Thank you.

@Aniela Your proposals are very real 😀
I especially liked the 1st one. Both bases because of the NaCl (and perhaps the glycosides) could have different micellar structures and therefore, might solubilize differently some fragrance components. Knowing that, perfumers use different chemicals accoding their partition coefficients to design a fragrance for a particular product (that’s not possible with an essential oil).
They other possibility is that the amine content in your PQ-7 could be interfering (or even reacting) with your fragrance.

Yey! I’m pretty smart😁
Joke aside, thank you for confirming my thoughts. I was also tempted to point the polyquaternium 7, based on past experiences with polyquats. I didn’t, because I feel almost like a fraud for not being a chemist/pharmacist/etc, and being less able to express my thoughts in chemical/professional terms.
But I’m working to get there😃
Thank you, again.

Hi, thanks for your reply!
Well, we purchased the FO like any other manufacturer, we started experimenting with the hand wash, it turned out great! then they got FO for Shower gel production too based on that. I didn’t sus my Polyquat7 because it has no odor to it though. Lamesoft smells on it’s own. the final product (shower gel) smells like raw SLES, although it’s the same SLES i use in the hand wash ..

Another thing i failed to mention, hand wash has citric acid i used to buffer, but not the shower gel since it doesn’t need any
