  • Patent number: 9370573
    Abstract: Polyamide compositions useful for personal care are disclosed, including film-forming concentrates and emulsions. Ethanol-based concentrates comprise a hydrophobic polyamide, which comprises a reaction product of either (a) a dimerized fatty acid, at least one C2-C4 carboxylic acid, and a polyamine component comprising ethylenediamine and 1 to 30 eq. % of one or more di- or triamines; or (b) a dimerized fatty acid, at least 50 wt. % of a C16-C22 unsaturated carboxylic acid, and at least one C2-C6 diamine. Personal care applications for the concentrates, including continuous sunscreens, fragrant body sprays or splashes, anti-acne medications, are included. Water-in-oil emulsions comprising the hydrophobic polyamides are storage-stable and provide water-resistant SPF for products such as sunscreens and body lotions.

  • Patent number: 4853460
    Abstract: Hot melt polyamide adhesive compositions are disclosed which exhibit long open assembly times. The polyamides are the condensation products of an acid component consisting essentially of a polymeric fatty acid and a dicarboxylic acid, and an amine component consisting essentially of a cyclic diamine, a non-cyclic aliphatic diamine and, optionally, additional organic diamines.
