I think 'Galaxolide 50' refers to an actual product - sold as 'Galaxolide 50' - rather than pure Galaxolide diluted by weight to 50%. So if you or your supplier are diluting 100% Galaxolide, you need to take this into account. You'll have to contact your supplier to see what they're doing.
The formula should also specify, say, ten parts of 'Galaxolide 50' rather than ten parts of Galaxolide at 50% dilution.
I was given the information by a friend who works in the industry. He's not a fully qualified perfumer but his job is to make reduced priced versions of fine fragrances for different markets, so he'll be given a formula and told to make it for a certain price per kilo. I'm pretty sure you need to know your materials for that sort of work.
