Carbomer 956/934P/974P/971P application in oral care gels and toothpaste

2022-08-02 18:24:06

The toothpaste market is undergoing rapid premiumization, with consumers demanding greater levels of performance from oral care products. As a result, more products are arising with specialized benefit claims, such as enamel-sensitivity and management of gum inflammation.

As the top leading manufacturer of polyacrylic acid, carbomer, NM-Carbomer such carbomer 956, 934P ,974P ,980G, 971P have added value to oral care products. NM-Carbomers are used as efficient thickeners/co-binders in a variety of oral gel and paste formulations, both aqueous and anhydrous, including those with anti-cavity, tooth sensitivity protection, natural ingredients, whitening capabilities properties.

Here is NM-Carbomers advantages to oral care gel , the toothpaste :

  • Efficient thickening and binding properties in hydrous / semi-alcoholic formulations, in addition to being the preferred thickener for anhydrous compositions
  • Great rheology leading to better aesthetics, such as ribbon stand-up and good clarity gels
  • Synergistic co-thickening properties with either cellulosic polymers or natural gums, for improved formulation
  • Consistent lot to lot uniformity and lower bioburden, due to their polymerization property, and does not support microbial growth when compared to natural cellulosic polymers and gums
  • Superior mucoadhesive properties compared to other polymers, allowing for prolonged active or flavor retention and muco-protective capabilities

NM-Carbomer 956, 934P, 974P, 980G are highly efficient rheology and impart several desirable characteristics to oral care gels, toothpaste formulations:

  • Viscosity
  • Yield Value
  • Low Thixotropy
  • Clarity

The combination of NM-Carbomers ability to build yield value with low thixotropy provides for a clean, non-stringing ribbon of toothpaste coming out of the tube. From aesthetic and practical perspectives, this means that toothpaste formulations based on NM-Carbomers:

  • being pumpable
  • leave minimal solids residue on the tube rim
  • stand up well on the brush
  • can be used to make clear gels

As well as being efficient thickeners and binders, NM-Carbomers deliver the added benefit of bio adhesion in oral care gels, toothpaste. NM-Carbomers can be used to aid in the adhesion and delivery of dental formulations such as whitening and desensitizing treatments to the teeth. And they help to enhance the bioavailability of active ingredients such as fluoride in oral

care applications. The microgel structure of NM-Carbomers also imparts a shear-thinning property to the system. When

a shear force is applied (squeezing the tube), the microgel structure flows like a liquid. After the shear

force is removed, (stop squeezing the tube) the original high viscosity is recovered quickly, In High clarity products are routinely made using NM-Carbomers in the personal care and pharmaceutical industries. This is another reason why these polymers are key ingredients in many gel type toothpastes and transparent oral care products.
