Embodiment 1

[0120] Example 1: Examples A and B

[0121] Examples A and B are leave-on oral care gel compositions shown in Table 1 below, wherein the amounts of components are described in weight percent ("wt%"). The examples were prepared by conventional methods. Example A is a comparative gel composition containing sodium hyaluronate (as a source of hyaluronic acid) but no trehalose. Example B is the gel composition containing sodium hyaluronate and 10% by weight trehalose of the present invention.

[0122] Table 1: Examples A-B - Gel Compositions

[0123]

[0124] *Sodium hyaluronate with a weight average molecular weight of about 1,400,000 Da.

Embodiment 2

[0125] Example 2: Barrier Protection Test

[0126] The barrier protection test is described here. This test evaluates the barrier protective ability of a leave-on oral care composition by treating cells covered with a sample with capsaicin.

[0127] cell culture :

[0128] Human gingival epithelial (HGE) cells were maintained in a 37°C incubator, CO 2 Saturation is 5%. Dulbecco's Modified Eagle's Medium (DMEM, Gibco) was supplemented with 10 wt% fetal calf serum and 1 wt% penicillin-streptomycin to prepare a complete medium for these cells, which was changed every 2-3 days.

[0129] Barrier Protection Assay by Real-Time Cell Analyzer (RTCA) :

[0130] Barrier protection of samples was monitored using Impedance-based Real-Time Cell Analyzer (RTCA) xCELLigence RTCA DP (ACEABioscience Inc., San Diego, CA) equipment. Add 50ul of complete medium to the E-plate to get a background reading, then add 100ul of cell suspension. Incubate E-plates containing 28,000 cells / well ...

Abstract

The invention discloses a leave-on oral care composition for promoting gum health, which comprises a hyaluronic acid and a gum-strengthening polyol.

Description

technical field [0001] The present invention relates to leave-on oral care compositions for promoting gum health in a user. In particular, such oral care compositions comprising hyaluronic acid and gum strengthening polyols can be used to provide improved barrier function / protection and sensory experience to the user. Background technique [0002] Gum diseases such as gingivitis and / or periodontitis cause acute and chronic inflammation of the gums in the oral cavity. "Gingivitis" is a milder form of the disease. Symptoms of gingivitis may include: bleeding gums; and red, swollen, or puffy gums. If left untreated, gingivitis can develop into "periodontitis." With periodontitis, the gums break away from the teeth and create spaces called "periodontal cavities," which can become infected with pathogenic bacteria. Bacteria exist as biofilms on tooth root surfaces. Bacteria in the biofilm may attack the gums and the underlying alveolar bone, which supports the teeth. These ...
