  • Example 1 This example has ultra mildness because the relative levels of Cocamidopropyl betaine and sodium laureth sulfate are close to one another. Mildness is optimized when these two surfactants are close to a one to one anionic to amphoteric ratio on a molar basis. These two surfactants have comparable molecular weights.
  • Example 2 This example shows that mildness can be sustained even when raising surfactant levels of sodium laureth sulfate and sodium lauroyl sarcosinate. It is important to keep the relative ratio of cocamidopropyl betaine and sodium laureth sulfate close to one another (e.g., this ratio can range from 2: 1 to 1 : 1.5; preferably 1 :5: 1 to 1 : 1.5).
  • Example 3 This example shows mildness being further enhanced by the further addi ⁇ tion of polymer.
  • Polymer acts as a humectant, preventing moisture loss from the skin. It also reduces the penetration of surfactant into the stratum corneum.
