Description

Gel-forming composition for oral care products and oral care products comprising the same

Technical Field

The application relates to the technical field of oral care, in particular to a gel-forming composition for an oral care product and the oral care product comprising the gel-forming composition.

Background

Nowadays, more and more oral care products are used, and the topics of how to select the oral care products and what oral care products do not damage human bodies become daily topics which people pay attention to. The consumer basically considers the following general functions in selecting an oral care product:

1) whether or not there is damage to the teeth and oral cavity is very minimal;

2) has high tooth cleaning and whitening effects;

3) can inhibit the reproduction of undesirable bacteria in oral cavity and keep the oral cavity fresh for a long time.

With the increasing living standard of people, consumers pay attention to the above ordinary functions and pay attention to the indexes of paste transparency, paste stiffness and the like of oral care products such as toothpaste.

The term "paste stiffness" in this application refers to the degree to which a toothpaste or a coagulant stands upright.

The term "transparency of the paste" in the present application refers to the degree to which the paste is i.e. transparent. At present, there is a commonly used international method for measuring liquid transparency: a white disc, about 25 cm in diameter, is taken and placed in the liquid and is held by the human eye until it is invisible. The depth to which the disc is submerged is the transparency of the liquid. However, this detection method is not very suitable for detecting the transparency of the paste.

There is no clear disclosure in the prior art of products or related techniques that improve the paste clarity and paste stiffness of oral care products.

Comparative examples 1-3 and examples 4-8:

a toothpaste is prepared from the following raw materials by conventional process. For example, but not limited to, the following methods:

a method of making an oral care product comprising the steps of:

1) dissolving saccharin sodium, tetrasodium pyrophosphate and sodium fluoride in water, dispersing gelling agents such as cellulose gum and carbomer with PEG, mixing the two, adding sorbitol, and stirring to form a gel water phase;

2) and transferring the glue phase to a vacuum mixer, adding friction type silicon dioxide and thickening type silicon dioxide simultaneously, stirring uniformly in a vacuum state, adding essence and sodium dodecyl sulfate, and stirring uniformly again to obtain the oral care product.

The cellulose gums used in comparative examples 1-3 and examples 4-8 were run in parallel for the same selection. The different species of cellulose gum selected from the group consisting of hydroxyalkyl methyl cellulose, carboxyalkyl methyl cellulose, hydroxyalkyl cellulose, alkyl cellulose, carboxyalkyl cellulose and salts thereof are very similar in test results and are not described repeatedly.

The acrylate polymers used in examples 4-8 were run in parallel for the same selection. The different types of acrylate polymers are very similar in test results and are not described repeatedly. See table below:

the comparative examples and examples described above make it possible to obtain:

1) under otherwise identical conditions, the addition of only the cellulose gum and not the acrylate polymer used in combination resulted in an oral care product with unsatisfactory paste stiffness and paste clarity (see comparative example 1 data).

2) Under the same other conditions, only the cellulose gum is added without adding the acrylate polymer which is used cooperatively, and even if other gelling agents such as carrageenan or xanthan gum are added, the paste stiffness and the paste transparency are not helped, but are reduced (see the data of comparative examples 2 to 3).

3) Under otherwise identical conditions, the paste stiffness and paste clarity were directly and substantially improved using the inventive gel-forming composition formulation (see examples 4-7).

4) Under otherwise identical conditions, the use of the inventive gel-forming composition formulation, but too little of the total mass of the formulation in the oral care product, results in a substantial decrease in paste stiffness.
