THE INVENTION CONCERNS BIOLOGICAL EXTRACTS OF FLUIDS (SERUMS, AMNIOTIC LIQUIDS, MILKS), OF ANIMAL TISSUES (SKIN), USED AS ACTIVE PRINCIPLES IN COSMETOLOGY. THESE EXTRACTS CONTAIN PEPTIDIC CONSTITUENTS OF LOW MOLECULAR WEIGHT (500 TO 50,000DALTONS), THERMO-RESISTANT UP TO 80C AND STABLE IN A PH RANGE BETWEEN 2 AND 9. THEY ARE OBTAINED BY THERMAL DEGRADATION, DIGESTION OF ENZULAR-MOLECULAR TAMPISAGE AND TAMPISAGE. . THE CHARACTERISTICS OF THESE EXTRACTS: DEMONSTRABLE IN-VITRO ACTIVITY, SAFE AND STABILITY, ARE PARTICULARLY ADVANTAGEOUS FOR USE IN COSMETIC PRODUCTS. |
