The moisturizer contains an amino acid called polyglutamic acid that increases moisture and prevents water loss for softer skin; it also contains evening primrose and lavender oils.
Values for the endpoint biuret method were ~30% lower than expected for gelatin, possibly reflecting decreased reactivity of a proline-rich protein, and were ~30%-40% lower than the expected value for weighed peptide content for polylysine and polyglutamic acid (both poly amino acids ~10-30 residues in length).
