|This HLB (Hydrophile-Lipophile Balance
System) Calculator requires very little input and will save many precious
hours for those who do HLB calculations by hand. The following describes
the basic use of the HLB Calculator.
The Calculator is made up of four
parts. All ingredients are added to the phases by using convenient
drop down menus. There are four separate tabs (Water Phase, Oils &
Waxes, Emulsifiers and Miscellaneous) that have many ingredients already
in them. Any ingredients not found will need to be entered into the
respective tab for that phase. When you leave the tab it will automatically
put the items in alphabetical order.
Water Phase Enter all ingredients
that go into the water phase excluding water. Since water percentage
is automatically calculated, the total of the formula will always equal
Oil & Waxes Phase Enter all
ingredients that would be included in this phase. HLB is automatically
added. Enter the percentage of total for that oil/wax and the overall
portion of HLB that the oil contributes to the mix will be calculated.
Emulsifying Phase HLB is achieved
by balancing the two emulsifiers to achieve the weighted HLB of the oils
from the oil phase. The program will not allow the use of emulsifiers that
would produce an incorrect balance. First enter the percentage of total
for the emulsifiers. The actual percentage of each emulsifier will be calculated
based on the weighted HLB of the oils and waxes. The first emulsifier should
have an HLB lower than the weighted HLB of the oils and waxes. The
second emulsifier should have an HLB higher than the weighted HLB of the
oils and waxes. There are normally wide ranges of emulsifiers that
meet those requirements.
Misc. Phase This phase is for Fragrance,
Essential Oils and preservatives.
A bonus with this calculator is the
Formulary tab. All the values from the calculator are carried over into
the Formulary tab. By entering the size of the batch and the units,
i.e. 16 oz, the weight of each ingredient for the recipe will be calculated.
Next, print out the page and the recipe is ready!
The HLB Calculator is to be used
by people that already know the HLB System or are in the process of learning
it. The HLB System is not a foolproof system. Its a tool.
There are a number of ingredients that have different required HLB values
and HLB values. For example: Lecithin has a HLB value of 4-9 depending
on the manufacturer. You will need to know the required HLB of your
Lecithin according to the manufacturer it was purchased. A large
list of required HLB and HLB values is included in this calculator.
The user will have to change any values that may differ from the ones in
the calculator to reflect the values of the ingredients the formulator
Detailed instructions are included
with the calculator. This calculator is a Microsoft
Excel workbook and has been tested with Excel 2000 and Excel XP. Due to
the nature of this product, refunds will not be given.
