摘要:
A structure which is useful for making containers for dentifrices, such as tubes, is comprised of a structure where the layer which contacts the dentifrice consists of a blend of polybutylene terephthalate and polyethylene. Other layers can consist of adhesives, paper, foils, other polymers and the like depending on the properties desired. A polybutylene terephthalate-polyethylene layer has been found to have a low degree of absorption of flavorant.

摘要:
A dentifrice composition containing an anionic surfactant, and a minor amount of a water soluble positively charged protein hydrolysate having an isoionic point above 7, and a Bloom gel value of zero, selected from the group consisting of a protein hydrolysate fraction containing high concentrations of basic amino acids or a quaternary derivative of a protein hydrolysate, which counters the irritation to the oral tissue and reduces the bitterness caused by said anionic surfactant, without reducing its foaming and cleansing properties.The present invention relates to novel oral compositions which are substantially non-irritating to the oral tissue, comprising an anionic surfactant and a positively charged water soluble protein hydrolysate fraction containing a high concentration of basic amino acids or a quaternary derivative of a protein hydrolysate. The protein hydrolysate fraction is obtained by extraction from a partially hydrolyzed protein mixture by means of ion exchange separation with an anion exchange resin. The quaternary derivative is obtained by quaternizing a protein hydrolysate mixture by chemically modifying the available terminal amino groups of the protein.
