According to Essential Oil Safety by Tisserand and Young, oakmoss absolute should be limited to no more than 0.1% in lotions and creams (IRFA categories 4 and 5). Soap is in a different IRFA category (9 if memory serves me right), but my experience is that the IFRA recommendations for lotions are often about the same as for soap. Per Tisserand, oakmoss is a high risk skin sensitizer.
To translate that 0.1%, you would use 1 ounce of oakmoss absolute in 1000 ounces of soap. (For those who think in grams, substitute the word gram where you see ounce.)
A mixture of 1 oz oakmoss in 9 oz jojoba is a 10% mixture by weight. If you only have 7 oz jojoba, then you'd mix 0.78 oz oakmoss with the 7 oz of jojoba to get the same 10% mixture.
I have heard of this oakmoss idea, but if your soap smells so bad that people wrinkle their nose, I question whether oakmoss is a true solution to that problem. If the lard is rancid or contaminated somehow, then, yes, there will probably be a bad odor in the soap, but the solution for that kind of problem is to not use bad-smelling fats to make soap, whether it's lard or any other fat. If lard smells clean and mild, the resulting soap should be likewise.
I make lard soap, often with 60-80% lard in the recipe. I've used lard I've rendered myself and I've used several commercial brands (usually Armour). I once did a small batch with lard rendered from collected bacon fat drippings just to say I've done it. I've never had the soap smell nasty.
"...Does this amount sound safe to you?..."
I don't know. You haven't said anything about how you intend to use it. I mean, I know you want to use it in lard-based soap, but that's about all I know. Are you planning to use all of this of jojoba/oakmoss mixture in your soap? How big of a batch?
