[0118]

[0119] *Sodium hyaluronate with a weight average molecular weight of about 1,400,000 Da.

Embodiment B

[0120] Example B: Viscosity and Mucoadhesion Data

[0121] The viscosity profile of Example 1 according to the invention and several benchmark products available on the market (Examples 6 to 9) were tested according to the rheological test described above. The results for the consistency coefficient K and velocity index n are listed in Table 2 below.

[0122] The mucoadhesion of the inventive examples and reference products (Examples 6 to 8) was tested by using the mucoadhesion test described above. The results are also summarized in Table 2 below.

Embodiment C

[0131] Example C: Consumer Sensory Test

[0132] Consumer sensory testing was conducted to measure consumer preference for Example 1 of the present invention relative to the benchmark products (Examples 6 to 9).

[0133] Qualified consumer groups are instructed to use series test products with no knowledge of product identity ie brand, ingredients, etc. A questionnaire was designed to obtain consumer ratings on direct questions (DQs), including (1) whether the product spread / spreads easily on the gums; (2) did the product show consistency in thickness / stickiness; and (3) did the product spread over the gums? Whether to stay on it for enough time. The grades given by consumers are divided into three levels, where "+++" means that more than 60% of consumers are preferred, "++" means that more than 40% but less than 60% of consumers are preferred, and "+" means less than 40% of consumers is preferred. For each aspect, Inventive Example 1 was scored as "+++", surpassing Compa...

Abstract

Leave-on oral care compositions comprising a hyaluronic acid or a salt thereof and having good spreadability and improved retention period are provided for promoting gum health of a user.

Description

technical field [0001] The present invention relates to an oral care composition for promoting gum health of a user, the oral care composition comprising hyaluronic acid or a salt thereof. In particular, such oral care compositions provide leave-on formulations that provide good spread and hold properties in order to provide improved sensory experience and gum health benefits to the user. Background technique [0002] Users with gum problems are often limited to brushing with toothpaste at home as a solution. This mechanism can help cleanse and control plaque and bacterial and associated toxin attacks on the host. However, due to the limited dwell time of the brushing, ie 2 minutes, there is little time to repair or even strengthen the host tissue. Therefore, users desire a regimen that can be applied to the host tissue for a longer period of time and repairs, strengthens and rejuvenates the gums. To meet the expectations of such users, various gel or ointment products th...
