How to make fragrance last longer in hair when using shampoo?
Hello, It’s me again.
Today I want to ask: When we do the shampoo, how to make fragrance last longer in hair?
A friend said if I mix fragrance with silicone before adding to shampoo, the fragrance will last longer. Is it right? -

1501 Hi you can use perfume fixatives like Glucam P 20, also use bottom notes like Sandal wood & resins.
Good luck Catherine Pratt -

Do you know the ratio between Fragrance and Gluco P20? Someone said it’s 5:1, another said 1: 0.6

Hello, speaking of Glucam P20, do you have an experience with it? I am interested of this ingredient as a humectant, instead of using glycols - propylene, pentylene. A local supplier sell this ingredient.

+1 for this comment. Oud and Vanillin are also pretty ‘fixative’ in their olfactive profiles.

I found that if you use too much Glucam P 20 it will dull the scent. Usually from my reading, around 5% is added calculated from the fragrance usage rate… so not much.

@1501 I think @”Dr Catherine Pratt” makes a good call with Glucam P20 there, and 1 - 2% w/w is more than enough @Cafe33. I’ll add though that deposition of fragrance oils parallels deposition of any other oil onto the hair, so your surfactant composition is a key factor not to be overlooked. Des Goddard wrote extensively on the topic of coacervate dilution-deposition of actives and oils, as has Dr. Bob Lockhead.

Yes, my apologies, I remember now. 5% resulted in dull fragrances. The usage rate I read about is 1-5% calculated on the basis of the fragrance.

I was searching for different humectants to use and came across Glucam P-20 and it was advertised as a powerful humectant. So I used it in a moisturizer and when I smelled the moisturizer I was shocked by the scent because I hadn’t added any fragrances and the only new ingredients I had used were potassium azeloyl diglycinate and Glucam P 20, and sure enough I opened the bottle of Glucam and found that odd smell. I thought something was wrong with it and did a little research to find out it’s used as a fragrance fixative.
It does have a nice skin feel, where it has a light emollient feel, but the scent is off putting for me, but I also have a really strong sense of smell. I can’t remember how much I used in it, without looking through my formulas. If you add fragrance to your formula it probably wouldn’t be bad, or if you used a small percentage in your formula.
I was searching the forum to see if anyone has used it in a perfume. I am going to do a little experimenting with it and see if it helps top notes last longer and if it gives the fragrance more body.
