Two retaining products were prepared by utilizing waste protein of chromium containing solid wastes. One retaining product was prepared by alkaline protein hydrolyzate while the other was prepared by acidic protein extracted from chromium containing solid wastes (chrome shavings). Whereas two retaining products were commercial and applied in the same dosage in goat skin processing for comparison of results. The impact of four different leather retaining products was evaluated by analyzing data from standard physical testing of leather. ANOVA and Duncan's multiple range tests were employed to compare the physical testing methods. Results revealed that retaining product prepared from the recovered protein was effective as a retaining product. The results of ANOVA for various parameters such as tensile strength (N/mm2), tear strength (N/mm), etc. were found significant (p at the most 0.05).
