TEA-triethanolamine


 TEA-TRIETHANOLAMINE


TEA Stearate is the triethanolamine salt of stearic acid used as a 
surfactant-cleansing agent and a surfactant-emulsifying agent in a wide variety 
of cosmetic formulations. Published data on TEA Stearate as an individual 
ingredient were not available, but data on its two components, TEA and stearic 
acid, were previously reviewed and considered adequate to evaluate the safety 
of TEA Stearate. Information from the earlier reports was summarized in this 
report and updated with more recent data on TEA. These data were consistent 
with the conclusion that TEA is safe for use in rinse-off cosmetic formulations, 
that its concentration should not exceed 5% in leave-on formulations, and that 
in no case should it be used in products containing N-nitrosating agents. 
Stearic Acid was found safe as used. Because the TEA salt of stearic acid is not 
expected to exhibit any toxic effects not seen with the separate moities, these 
conclusions, including the concentration limit for TEA, are considered appli￾cable to TEA Stearate, once adjusted for the appropriate molecular weights. 
Therefore, it is concluded that TEA Stearate is safe as used in cosmetic for￾mulations designed for discontinuous, brief use followed by thorough rinsing; 
that it is safe in concentrations not to exceed 15% in formulations intended for 
prolonged contact with the skin; and that it should not be used in products 
under conditions resulting in N-nitrosation reactions. Key Words: TEA Stea￾rate-Stearic acid-TEA-Triethanolamine.

Food Composition Tables by Sama chifen

Food composition data and food composition databases Early food composition studies were carried out to identify and determine the chemical nature of the principles in foods that affect human health. These studies were also concerned with the mechanisms whereby chemical constituents exert their influence and provided the basis for the early development of the science of nutrition (McCollum, 1957), and they continue to be central to the development of the nutritional sciences. Current knowledge of nutrition is still incomplete, and studies are still required, often at an ever-increasing level of sophistication, into the composition of foods and the role of these components and their interactions in health and disease. Somogyi (1974) reproduced a page of the earliest known food composition table, dated 1818. Ever since, it has been customary to record food composition data in printed tables for use by both specialists and non-specialists. While printed tables will continue to be produced...
