Definitions

  • the present invention relates to pasty dentifrices containing 1 to 30% by weight of polyolefin wax with an average particle size of 5 to 45 ⁇ m.
  • the invention further relates to the use of polyolefin wax with an average particle size of 5 to 45 ⁇ m as an abrasive in pasty dentifrices.
  • Dental care products generally contain abrasives that support the mechanical cleaning effect of the toothbrush.
  • No. 3,955,942 describes abrasives which are contained in toothpaste and which consist of agglomerates of small inorganic particles.
  • DE-A 21 04 473 describes waxes as a matrix substance for active substances contained in toothpaste.
  • abrasives based on inorganic material lead to damage to the tooth enamel due to their coarse grinding action or, particularly in the case of older people with partially exposed dentin, to the tooth necks.
  • the object of the present invention was therefore to provide pasty dental care products with a mild but effective abrasive.
  • Suitable polyolefin waxes of the dental care agent according to the invention are polymers of ethylene, including, in addition to linear polyethylene of high, medium and low density (HDPE, MDPE, LLDPE), especially high-pressure polyethylene of low density (LDPE); furthermore syndiotactic and preferably isotactic polypropylene wax, and copolymers of 0.1 to 99.9 mol%
  • Suitable waxes of the dentifrice according to the invention have an average particle size in the range from 5 to 45 ⁇ m and preferably in the range from 8 to 15 ⁇ m.
  • melt viscosity in the range from 100 to 1000 mm 2 / s, preferably in the range from 110 to 500 mm 2 / s, measured according to DGF M-III 8 at 120 ° C.
  • Polyethylene waxes from the high-pressure and low-pressure processes ie waxes from ethylene homo- or C 3 - to Cs copolymers whose density is in the range from 0.910 to 0.970 g / cm 3, are particularly suitable.
  • the polyolefin waxes according to the definition are generally known, in some cases commercially available and otherwise obtainable in a known manner, for example by Ziegler, metallocene (EP-A 602 509, EP-A 571 882), Phillips or high-pressure polymerization of ethylene or alkylene 1-enes, or by degrading the high molecular weight olefin polymers on which the waxes are based (Ullmanns Encyklopadie der Technische Chemie, 4th edition, vol. 24, pp. 1-49, in particular pp. 36 to 45, (1983)).
  • the waxes are generally micronized using standard methods.
  • polyolefin waxes whose density, measured according to DGF M-III 2a (57), is in the range from 0.900 to 0.990 g / cm 3 , preferably in the range from 0.910 to 0.970 g / cm 3 .
  • the dentifrice according to the invention contains the ingredients and types customary for dentifrices in terms of type and quantity (GA NOWAK, The Cosmetic Preparations, Volume 2, 3rd Edition 1984, Chapter 15) such as, for example, cleaning and polishing materials, for example calcium carbonate , surface-active substances, active substances, mucilages, thixotropic agents, taste and aroma substances, humectants, preservatives and coloring substances.
  • cleaning and polishing materials for example calcium carbonate , surface-active substances, active substances, mucilages, thixotropic agents, taste and aroma substances, humectants, preservatives and coloring substances.
  • the polyolefin waxes are contained in the dentifrice according to the invention in an amount of 1 to 30% by weight, preferably 5 to 15% by weight, based on the dentifrice.
  • the conventional inorganic abrasives such as precipitated calcium carbonate, silica, calcium phosphate or aluminum oxide, may also be present in minor amounts in the dentifrices according to the invention.
  • the content of the wax in the mixture of polyolefin wax and solid inorganic constituents of the dentifrice is then generally in the range from 3 to 60% by weight.
  • the dentifrice according to the invention can be in the form of toothpaste, toothpaste or tooth gel.
  • the dentifrice according to the invention can be briefly swollen, for example, by mixing the components, for example in a mixer of the Bäko-Mix brand, and subsequent homogenization can be obtained under vacuum.
  • the RDA is determined using a method from Missouri Analytical Laboratories, Inc.
  • RDA is rasion for radioactive dentin waste first In this test, extracted human teeth are irradiated radioactive and then cleaned with the test toothpaste and a reference material. The radioactivity is measured in the abrasion.
  • the RDA value for the reference material is set to 100 and the test measured values based on it.
  • Example 1 The experiment of Example 1 was repeated, but the polyethylene wax Luvitol® PE 10 was completely replaced by silica gel.
  • the toothpaste was found to have a rough, highly abrasive effect and the tooth necks were attacked, the RDA value was high.
