Embodiment

[0077] Hereinafter, the present invention will be specifically described by citing examples and comparative examples. However, the present invention is not limited to the following examples. In addition, in the following examples, unless otherwise specified, % all represent mass %.

[0078] EXAMPLES AND COMPARATIVE EXAMPLES Dentifrice compositions (toothpastes) having the compositions shown in Tables 1 to 4 were prepared according to the following method, and the following evaluations were performed. The results are shown in Tables 1-4.

[0079] Preparation of test dentifrice compositions:

[0080] (1) After mixing and dissolving water-soluble components (except binder, propylene glycol, etc.) in pure water at normal temperature, add and mix sorbitol and thickening silica to prepare phase A.

[0081] (2) Disperse the binder in propylene glycol at room temperature to prepare Phase B.

[0082] (3) Add and mix phase B to phase A which is being stirred to prepare phase C.

Abstract

Provided is a dentrifice composition that has a strong anti-staining effect and stain removing effect, low oral mucosa irritability, excellent properties such as taste and foaming when used, and good shelf life. The dentifrice composition is obtained by mixing (A) an acylamino acid salt, (B) an alkylsulfate, (C) a linear water-soluble polyphosphate represented by the following general formula (1) Mn+2PnO3n+1 (1) (where M is Na or K and n is an integer of 2 or 3), and (D) polyethylene glycol, and is characterized in that the amount of component (C) added is 0.3 to 1.5 mass% and the amount of component (D) added is 0.3 to 3 mass%. Furthermore, the dentifrice composition is obtained by mixing in (E) one or more water-soluble polymer compounds selected from carrageenan, xanthan gum, sodium polyacrylate, and hydroxyethyl cellulose sodium.

Description

technical field [0001] The present invention relates to a dentifrice composition, which has a high effect of inhibiting stain adhesion and removing stain, is less irritating to the oral mucosa, has excellent taste, foaming, etc., and has a good shelf life. stability. Background technique [0002] Stains that are a kind of tooth stains are formed due to oral proteins such as tannins contained in coffee, tea, albumin, etc., metal ions, and the like. Stains attached to the tooth surface are one of the main issues of oral aesthetics. As means for solving the problems caused by the stain, it is effective to remove the stain or suppress the adhesion of the stain. In order to solve the problems caused by stains, many dentifrice compositions have been proposed so far. [0003] For the removal of stains, removal has traditionally been carried out by the mechanical action of abrasives mixed in the composition. However, abrasives cannot avoid the abrasion of the oral mucosa of the ...
