Ditto what DeeAnna said. The next step is figuring out the % of butterfat in your formula. If you know what % butterfat is in the cream, use that. If you don’t know, here’s some info from Wikipedia:
45% Manufacturer's cream
36% Heavy whipping cream
30% Whipping cream or light whipping cream
25% Medium cream
So, assuming you have “medium cream”, to formulate on SoapCalc:
(1) KOH
(2) 14 oz
(3) Use the
water:lye ratio button. Type in 3:1 (Failor recipes use this)
(4) Use 0% superfat - Olive Oil is high in unsaponifiables. In LS you want to saponify as much of the fatty acids as possible, hence 0% SF
(6) 75% olive oil, 25% Milk fat, any bovine (scroll up from olive to find this.)
(7) Calculate recipe
On the View page, it should say:
8.4 oz or 237 grams of water (rounded)
2.8 oz or 79 grams of KOH (rounded)
You already have
152 grams of Water (rounded) So 237g minus 152g = 85g of water
50 grams of KOH (rounded) So 79g minus 50g = 29g of KOH
Temperatures are important in making LS. So make your lye solution and allow it to cool to
140°F.
Warm your already made soap to
160°F.
Add the lye solution to the warmed soap while stirring. SB to trace. This may go quickly or up to 45 minutes normally. (Your guess is as good as mine. LOL) Once the lye solution is fully incorporated, you can either stop there, cover it and allow it to cure for 1-2 weeks (CP) or HP by whatever method is most comfortable for you.
Before dilution, you need to test your soap to make sure all the lye has been saponified and there is no excess lye. You can do this by one of two ways.
1) Stick a knife in the soap and then dip it into a glass of water. Stir. If the water is milky, let the soap sit another day or 2 or 3 until the water tests clear, or almost clear before diluting.
2) Put 1 drop of phenolphthalein (10% solution) on the dipped knife. If the drop turns fuschia, there’s still some excess lye present. If it tests clear, you're good to go. Carrie Peterson’s youtube video for making Glycerin LS shows how to test LS with pheno drops at about 5 minutes into the video.

DILUTION
The recommended ratio for 100% olive oil castile paste to water is
15-20% soap to 85-80% (boiling) water for dilution. This is done range top (or crock pot) on Med-Low to Low and may take several hours. The object is not to “cook” the LS, but rather to get the paste to absorb all the water. If a film forms on the surface, add water a little at a time until the film clears. You can break up the paste chunks with a spoon as needed. No matter how sorely tempted (LOL), do not use your SB. Just be patient and let the soap do its thing. This results in thin LS, but that’s just the nature of the beast! You will be surprised how well it lathers. You can then thicken with salt.
Special Tip: You can also use .5 oz. table salt (very important it be plain table salt, just the cheap stuff) dissolved in 1.5 oz. distilled (warm) water to naturally thicken the soap prior to adding fragrance. We use about 12 ml of the salt solution in 16 oz. to get a very thick soap. Give it a try!
