Usage Rate Calculation for GLDA and TransMoist™

I have questions regarding the usage rates of two specific ingredients:

• GLDA (Tetrasodium Glutamate Diacetate, 47% Solution):
  • The recommended usage rate is stated as 0.1%-0.2%.
  • The SDS indicates 100%, but the product is a 47% solution.
  • Does the usage rate of 0.1%-0.2% refer to the solution as is, or do I need to adjust (e.g., double) the percentage to account for the 47% active ingredient concentration?
• TransMoist™ (PPG-24-Glycereth-24):
  • What is the recommended usage rate for this product?
