Moisture mist spray for the hair

Hi,
I'm trying to formulate a moisturizing spray for the hair and I don't know if I'm thinking down the right lane. I have used the following formula for several days and I'm noticing that my hair has taken on a strange texture (kinda gummy when wet) and I can't describe what it feels like when dry. Kinda like it has a film on it or something. Anyway can someone help guide me as to what I have overlooked or what I have done wrong?

Formula is as follows:
Purified water 69.45%
Aloe Vera powder- 200x .35%
Gluconolactone and Sodium Benzoate 1.75%
Herbal extract blend 7.5%
1,3-Propanediol 5.45%
Glycine Betaine - Beet Sugar extract 3%
Hyaluronic acid - 1% solution 10%
Chia seed extract 2%
Fragrance oil .5%

Herbal blend consists of:
Horsetail leaf extract 
Sage leaf extract 
Nettle leaf extract 
Rosemary leaf extract 
Chamomile flower extract 
Lavender flower extract 

If I did my calculations correctly, the total amount of sodium hyaluronate would be .1% since the solution was 1% or am I thinking about that all wrong?

Any advice would be greatly appreciated. 

Tim

    How did you manage to get that high a level of HYA to mist-spray I wonder? Must be the lowest MW grade I guess? Anyhow, I'd put my money on that and the betaine. When I read "film" I think "polymer" and that HYA is the only member present. Glycine betaine absorbs very strongly to keratin, therefore the "gummy".
  • Thank you, ChemicalMatt for your reply. 

    To answer your questions, the spray was not much of a mist but the solution did spray out - more of a direct stream kinda. I do not know what grade of Sodium Hyaluronate was used as the 1% solution was pre-mixed and purchased from Formulator Sample Shop. It was a bit of a gel-like solution. The Glycine Betaine that I have was purchased from Ingredients To Die For and I have been able to use it successfully in a cleansing conditioner formulation but it is a rinse off type of product. The mist spray is a leave-in product. 

    If I were to remove the HYA and Glycine Betaine, would the aloe vera juice be enough to provide a moisturizing effect? What about using Panthenol or Hydroxypropyltrimonium Honey?

    pH not withstanding, that is very poor preservation.
  • Hi PhilGeis.

    Is the type of preservative not good or the amount is not enough? Any advice is welcome.
