Cosmetics Formulation Development

I would like to inquire about the formula that is alcohol gel. I see that Pro Polymer is used. Pro Polymer 0.5 % If you want the total volume of 1000 ml, use Pro Polymer Pro Polymer many grams is there a formula to calculate? Pro Polymer how many grams? yes

Hello, please study พื้นฐานการผสมเครื่องสำอาง

Have a look at the basic formula for mixing it. But it doesn't make sense. In the formula as total weight (g), volume (mL) cannot be calculated in the same way. Because if you want Alcohol 70% of the total volume It must be calculated anyway that it must be used. แอลกอฮอล์ how much volume(mL) from %concentration of แอลกอฮอล์ containing so that the formula is 70% alcohol which Pro Polymer supplied as a powder. It's not a liquid, so I'm going to put it in, so I feel conflicted and I'm not sure. Example from Alcohol gel formula. This one wants to get 1,000 mL of alcohol 70% in total (if starting with 95% alcohol, must use 736.84 mL ) Glycerin e 5% ( this one used 50 ml ????) Pro Polymer 0.5% (Is it 5 g at all??? ) 24.5% water ( 1000-736.84-50= 213.16 mL which is not 24.5% of 1000 mL already ) from the above formula Please give me some suggestions. I'm really confused.

Because mixing these substances are both liquid and solid. Therefore, volume (cc/ml) is not used in the calculation, but weight (g) is mainly used in the calculation. Weighing scales are a must. It is recommended to change the problem to make 1000 grams of Alcohol gel 70% and weigh all the substances in grams. Pro Polymer 0.5% x 1000 g = 5 g
