  • Patent number: 6461598
    Abstract: The invention relates to a process for conditioning and cleaning hair, which comprises contacting the hair with an effective conditioning amount of a series of novel salt complexes. These complexes provide outstanding conditioning effects to the hair and are very mild to the eye. The complexes are made by neutralizing a fatty ammonium compound that is cationic with an anionic compound, producing a salt complex. Optionally, the complex can be combined with dimethicone copolyol to produce extremely mild products suitable for use in shampoos, body washes, and cleanser. The mildness makes these compounds of particular interest in baby shampoos.

  • Patent number: 6410679
    Abstract: The present invention deals with the composition, and application of polyoxyalkylene glycol dicarboxylates, and complexes thereof. The complexes are made by a series of reactions which include reaction of an anhydride with a polyoxyalkylene glycol, then formation of a complex of the poly carboxylate with quaternary compounds. The complexes are useful as softening, anti-tangle, and conditioning agents for use in personal care applications due to their outstanding mildness.

  • Patent number: 6252107
    Abstract: The present invention is directed to a class of compounds that are made by neutralizing the amino group in an amphoteric surfactant with the carboxylic acid group. The complex has (a) lower irritation, (b) better foaming properties and (c) improved substantivity to a variety of substrates.

  • Patent number: 6239290
    Abstract: The present invention deals with novel emulsifiers that have excellent feel on the skin are essentially non-irritating to the eyes and the skin and can be used to make unique silicone in water and water in silicone emulsions. The compounds are esters made by the reaction of sorbitol and carboxy functionalized silicone compounds. The introduction of the silicone portion of the molecule into the compounds of the present invention results in improved emulsification efficiency of silicone oils, improved oxidative stability and improved liquidity of the sorbitan esters as well as an outstanding skin feel of emulsions made with said emulsifiers.

  • Patent number: 5854319
    Abstract: The present invention relates to a composition, process for preparation and use of a novel emulsion composition in the personal care industry. The composition when applied to hair provides outstanding lubrication, and delivers amino acids or proteins to the hair fiber. This aides in the manageability of the hair and remediates damage from treatment processes like permanent waving, dying and relaxing of the hair as well as environmental effects upon the hair.
