  • Patent number: 11376202
    Abstract: The subject of the invention is a wax-in-water emulsion containing at least one fatty acid ester of tetramethylpropylethylenediamine, which is intended to replace triethanolamine, known to decompose into nitrosamines when the preserved emulsion is packaged in a thermoplastic material. Moreover, this emulsion has the advantage of gaining shade depth and fluidity, especially in products rich in waxes.
