Understanding Retinol Concentration in Encapsulated Products

You're asking about the concentration of pure Retinol within the "Encapsulated Retinol" product and how to interpret the unit "65K.IU/g".

Based on the available product information, I cannot find the specific concentration of pure Retinol within the "Encapsulated Retinol" product you mentioned (Product ID 2162). Therefore, I cannot calculate the exact percentage of pure Retinol in a 2% usage of that specific encapsulated product.

Regarding the unit "65K.IU/g" (or 65,000 IU/g), this stands for 65,000 International Units per gram. International Units (IU) are a unit of measurement for the potency of vitamins and other biological substances. The conversion from IU to mass (like grams or milligrams) is specific to each substance.

For Vitamin A, the conversion factor depends on the specific form:

• 1 IU of Retinol is equivalent to approximately 0.3 micrograms (mcg).
• 1 IU of Retinyl Acetate is equivalent to approximately 0.344 mcg.
• 1 IU of Retinyl Palmitate is equivalent to approximately 0.55 mcg.

To convert 65,000 IU/g of Retinol to a percentage by weight, you would use the conversion factor for Retinol (0.3 mcg/IU):

65,000 IU/g * 0.3 mcg/IU = 19,500 mcg/g

Since 1 gram = 1,000,000 mcg, you can convert mcg/g to percentage:

(19,500 mcg/g / 1,000,000 mcg/g) * 100% = 1.95%

So, a concentration of 65,000 IU/g of pure Retinol is equivalent to approximately 1.95% by weight.

However, this calculation applies to pure Retinol. For an encapsulated product, the "65K.IU/g" would refer to the total potency of the encapsulated material, and the actual percentage of pure Retinol within that encapsulated material would depend on the encapsulation ratio and the concentration of Retinol used in the encapsulation process. Without the specific details of the "Encapsulated Retinol" product (ID 2162), I cannot confirm if the 65K.IU/g refers to the potency of the encapsulated product itself or the Retinol content within it, nor can I calculate the pure Retinol content in your 2% usage.

Other Retinol products available include Retinol (100% Pure Powder) and Retinol (50% liquid), which have clearly defined concentrations of pure Retinol.
