OK Light Thanks but which one? I am sorry to ask again but I wanna at least have all the correct ingredients to start out with...

GoddessOfEarth

What is that for: "CORRECTION: 1 tbsp HQ to 4 tbsp EUCERIN." ?

You know that's over 20%!

GoddessOfEarth

Ahh, I saw that BHP store on line. I was searching online before I found a shop locally.


PinkMoscato,

From that site, these are the choices:

Photographers' Formulary | Hydroquinone - 100 | 10-0670 100G

Photographers' Formulary | Hydroquinone - 1 lb | 10-0670 1LB

Photographers' Formulary | Hydroquinone - 10g | 10-0670 10G

Photographers' Formulary | Hydroquinone - 30g | 10-0670 30G

how is that over 20%, she explained that 5 tablespoons of eucerin is 100% lotion base and u have to replace one tablespoon out of the 5 with HQ to make a 20% concentration, so thats 4 tablespoons of eucerin and 1 tablespoon of HQ to make a 20% that sounds about right.

GoddessOfEarth

I was wondering about the 1 tablespoon HQ to 4 tablespoons Eucerin. That's a 25% mixture.

Just wondering about that line or if I missed something.

ondine

25% would be 3 parts eucerin & 1 part HQ. bec 1/4 of the mixture would be HQ

20% is 4 parts Eucerin & 1 part HQ bec 20% x 5 = 100% does that make the correction clearer? I hate when I make a typo that muddles what I'm trying to say. I need to become a better typist! Sorry again, guys!

PaulWalk

guys i was was wondering what would be 10% im not really good at maths? then?

PinkMoscato

I ALSO want to try a 10%.. anything higher than that sacres the crap outta me..

ondine

For a 10% concentration, you need to decide on the total amt of cream you want. Then, you divide that total amt by 10 from there, you need to SUBTRACT 10% from the total amt of cream. Then, you REPLACE that 10% of cream with HQ. Here's a simple example:

9 tbsp of Eucerin & 1 tbsp of HQ powder = a 10% concentration.

You might use 1 imperial cup as your total amt. Then, using google (or a calculator) it'll tell you how many mls makes exactly 10% of 1 cup. Just make sure to REMOVE this amt from your total cream volume & REPLACE it with this same amt of HQ.

PaulWalk

kk i kinda get it so im gunna by the 5lb Hydroquinone Formulary so i will simply just use one tablespoon of hq and 9 of Eucerin into my contanier? and that would be my week supply? soz for all the ques again just want to get it right the first time

ondine

No problem: I screwed up several times B4 getting something I really liked. Here's how to make your 10% HQ cream:

-in yr heat proof glass measuring cup, place 5 tbsp Eucerin lotion.

- add 1 tbsp of the HQ powder.

- on top of this add 4 more tbsp Eucerin lotion.

Cover with plastic wrap leaving a small opening for steam to escape.

place container in a pot of water = in depth to the level of your cream. Heat on the stove at med/high heat. When it boils, allow it to sit boiling for a while. Stir on occasion to ensure even blending & melting of the HQ. Use a thermometer (a lab one, a meat thermometer or a candy thermometer will do) to ensure it reaches 170 degrees. Stir well & recover with plastic, leaving a steam escape space. Remove pot from heat to cool. When warm, transfer blend to an opaque pump bottle. THis should make approx 1 week's worth when applying all over the body. This, of course, will vary depending upon the height & size you are. I am just under 5'2" & I weigh 100lbs. If you're 6'2" & weigh 200 lbs, well...you'll run out faster! Since it is so fast & easy to make, it doesn't matter that much.

ladydanielle

tiny gurl you ondine! I thank you so much for this recipe.

ondine

YEP! Tiny I am. Try it out & report back! If you can think of a way to improve it, then go for it. I'm thinking of adding a 0.5% concentration of RA (IF I can find a reliable source for raw Tretinoin!)

ninasky

i see - i guess the volumes are adequate then. I am not sure how much PG it would contain, i always thought percentage would be too low to dissolve HQ but then again i dont use eucerin.

i also notice some of you guys measure in ML and not grams. It is an important thing to note that 100ml of lotion may not necessarily be the same as 100g of lotion. Also I have never used tbsp it just goes easily wrong for me lol

Water/weight is more or less equal to eachother; 1g=1ml. This is how the ML was measured. However lotion is 'lighter' and you may find that more lotion is required for the correct concentration.

I am not too bothered with DPG, but i think it matters with lotion as this is my experience. Again, I factor in DPG into my compound, so my process is slightly different.

I would advise weighing in grams, the HQ is measured in grams, the lotion should be measured in grams also for the right HQ:lotion ratio and concentration.

I just think this is the part of mixing that could go wrong for new compounders, therefore causing them problems on application.

Eg 10g HQ + 100g lotion = 10% concentration

10g HQ + 100ml lotion (could equal 75g) = higher concentration ???

To be honest, 10% concentrations dont have to be that accurate - its when you go above and attempt to mix 20%.

...and im in UK, probably why it said i was up at 4am that time. Would never be caught up at that time lol

GoddessOfEarth

Eg 10g HQ + 100g lotion = 10% concentration <<<< I use that ratio, also. Well, in millileters.

I, just, bought the Eucerin lotion. I hope it's correct. It's the Original.


I hope you 'new' mixers have your:

Goggles
Masks
Gloves
Thermometer
Heat-Proof Beaker
Gram Scale(If you want to, actually, weigh your product...Ebay)
Pot/Pan you will use ONLY for your mixture

LightenNLift

if you didnt have a gram scale, how would that equation u listed convert to tablespoon or teaspoon?

GoddessOfEarth

You can use google for the utensil you're using. Hmm.. I'd say look up teaspoon/tablespoon of salt/sugar and see how many grams/millileters it equals.

Example: How many tablespoons of sugar is 20 grams.


But, since you're, already, doing a ratio, that should be ok, too.

ondine

1/2 tsp = 2.5 ml
1 tsp = 5 ml
1 tbsp = 15 ml

Hope this helps!

just wanted to weigh in. i tried compounding the sepi white. it is apparently very difficult to obtain the correct temps in order to get it to melt. I thought I was there and eventually tested my compound. It turned my skin a greyish pallor which took a lengthy time to clear. Just be careful to test on less prominent place on your body.
