Microformulation 
I was looking at a list of ingredients from a leave-in conditioner spray and the product was marketed as natural.

 I was curious what their preservative was because most of the conditioner sprays are going to be mostly water if it’s not for styling. I posted their ingredients.

The preservatives are Grapefruit Seed Extract, Leucidal Liquid filate, Citric Acid, and Sea Buckthorne  and maybe the essential oil blends (I’m assuming that part of the preservation in the seabuckthorn extract could be preserved with sodium benzoate (0.5%), potassium sorbate (0.2%)) ? Because when I looked at it on Making Cosmetics that’s what they used to preserve it at a pH of 3.5-4.5 ) Would the potassium sorbate and sodium benzoate count as part of the blended preservatives they used and is that why seabuckthorne is listed last? Am I wrong for assuming this? Because from what I understand those preservatives would not properly preserve aloe vera with that much water because I see that aloe vera juice is the second ingredient followed by a hydrosol. When I looked at the list of preservatives that Jane Barber put out she said that GSE and Leuconostoc/Radish Root Ferment Filtrate (Leucidal Liquid) was not recommended.  In the case of aloe vera/hydrosol which is very hard to preserve,
she said “it could be done with as much as 50% aloe vera or hydrosol and pass preservative test just ask supplier for the microtest or batch(or Certificate of Analysis) of aloe/hydrosol you buy - check that to see that it is lower than 100 cfu/gram/ml 
no staph, Candida albicans or gram negative bacteria”  At what percentages would all the preservative have to be to be effective if the aloe and hydrosol were 50%? Looking at the list of ingredients I could only speculate but the preservative system must be very good if they are selling it. Your thoughts?
