Makeup Remover Oil Stick
Hello everyone, I’m having a hard time getting
emulsion for my makeup remover oil stick.I have read lots of article on O/W and W/O
emulsion and I assumed my current formula is W/O. And I would like to make it
in a stick form.I think I understand how O/W HLB calculation
work so far and able to complete O/W formula with good emulsion. However, when
I try to do W/O formula that is where I got lost. I read something saying for
each oil/waxes/lipid RHLB will be difference in W/O formula and I can’t seem to
find any value table or calculation method on the internet.1. Are they using the same formula and same HLB
value for each lipid type to calculate W/O emulsion?2. Lots of material on internet saying W/O HLB
range is 46, if I were to use same calculating method as O/W, I don’t get
anything near 46 as my lowest oil has HLB of 7 so it won’t get any lower.3. I tried lots of experiment, blending Tween60,
Span60, PEG40, Tween20, PEG7 cocowash (not all at the same time) but 2 or 3
surfactants to get HLB between 4.7 to 13 nothing seem to get any good emulsion
(at the appropriate %). I assumed good emulsion mean both water and oil
blended until it get clear no cloud (the reason I thought this is because when
I get it to clear, I got smooth cream (solid) consistent that I wanted. But the
only time I would get my current formula to clear is where I add 20%30%
span60. yes I got the consistent I wanted but it probably isn’t sufficient (too
much span60).4. How do I know how many % of emulsion I need
in the formula? I have read a lot saying there is no complete formula and some
said 25% of lipid but if I do W/O then that will be lots emulsion?5. You kind advice on what emulsion agents I
need to use and how many % to get good emulsion on the formula below will be
much appreciated.Here is my formula, the rest of the % I left for
emulsion agents (don’t know if it is too much, please advise.)Phase 1 (water phase)
Natural Liquid Soap 18% (consisting of Potassium Hydroxide, Oil, Water)
Silica 4%
Butylene Glycol 3%
Propylene Glycol 5%Phase 2 (lipid phase)
Polyethylene Wax 8%
Sunflower Oil 28%
Cetyl Ethylhexanoate 9%Phase 3 (emulsion agent)
PEG7 Coco Wash 5.00%
This is where I have
problem withPhase 4 (Fragrance, Extracts, preservative)
Aloe Vera Extract (water soluble) 3.95%
Turmeric Extract 0.15%
Essential Oil 1%
Fragrance Oil 0.9%
Phenoxyethan + EHG 1%1. I heat
Phase 1 and 2 separately and put Phase 1 into Phase 2 (I assumed that what we do for W/O?)2. I then put Phase 3 in there and stir, when it get thick, I
put it back in double boiler.3. When it become liquid (preferably clear liquid, this is
where I have the problem) I take it out of double boiler and let it cool a bit
and put Phase 4 then stir and put in my twist up container.Any help or recommendation will be much appreciated, and thank
you in advance for your valuable time.
