Description

  The present invention relates to a dentifrice, and more particularly, to a dentifrice having a high refreshing feeling in use, which contains a rose petal extract and / or rose petal essential oil.

  Dentifrice is composed of various ingredients, but since it is used in the oral cavity, it is common to add a fragrance for the purpose of masking unpleasant taste and smell, and giving a refreshing feeling and refreshing feeling. Is.

  This fragrance is effective when it is sensed as a scent or taste in the nasal cavity or oral cavity during use. Conventionally, fragrances added to dentifrices include menthol, peppermint oil, spearmint oil, carvone, and anethole. Mint-based fragrances such as these have been often used (Patent Document 1).

  However, the mint-based fragrance brings a certain level of refreshing feeling to the dentifrice. However, when a large amount is added to give a strong refreshing feeling, there is a problem that it causes bitterness and irritation.

  Plant essential oils such as thymol, menthol, methyl salicylate (winter green oil), eucalyptol, carvacrol, camphor, anethole, carvone, eugenol, isoeugenol, limonene, ocimene, n-decyl alcohol, citronel, α-salpineol , Methyl acetate, citronellyl acetate, methyl eugenol, cineol, linalool, ethyl linalool, saflora vanillin, spearmint oil, peppermint oil, lemon oil, orange oil, sage oil, rosemary oil, cinnamon oil, pimento oil, laurel oil, Bactericidal dentifrices have been devised that expect the bactericidal action of plant essential oils such as cedar leaf oil and clove oil (Patent Document 2). However, these were not excellent in feeling of use because of their insufficient bactericidal action, strong bitterness and irritation, and poor taste.

  In addition, dentifrices with 1-6% rose seed oil reported to be effective for skin regeneration, wound reduction and restoration, and inflammation have been devised, but the addition of large amounts of rose seed oil has poor taste. The feeling of use was not excellent (Patent Document 3).

In the case of a comparative product, mint oil, anise oil, eucalyptus oil and orange oil are added instead of rose petal extract and rose petal essential oil.
(D) Xanthan gum, carrageenan and hydroxyethyl cellulose are added to the mixture of (C) and mixed uniformly, and then the remaining purified water is added to obtain a dentifrice.

<Sensory evaluation of feeling of use>
The feeling of use (taste, fragrance) during and after brushing was evaluated by a sensory test using 10 subjects. Toothbrushing, about 1 g of a dentifrice of each composition shown in Table 1 above was taken on a toothbrush and the teeth were brushed for about 5 minutes by a normal brushing method. The feeling of use in the mouth during and after brushing was evaluated according to the following criteria. The results shown by the average value are shown in Table 2.

<Evaluation criteria>
Rating: Evaluation content 5 points: There is no unpleasant taste and the fragrance is very refreshing.
4 points: There is no unpleasant taste and the fragrance is refreshing.
3 points: Slightly unpleasant taste and slightly scented.
2 points: Slightly unpleasant taste and aroma is not refreshing.
1 point: There is quite an unpleasant taste and the fragrance is not refreshing.

  As is apparent from these results, the dentifrice of the present invention using the rose petal extract (Inventions 1 and 2) and the dentifrice of the present invention using the rose petal essential oil (Inventions 3 and 4) do not contain this. Compared with the dentifrice (comparative product 5), the conventional toothpaste oil, anise oil, eucalyptus oil, and the toothpaste using the orange oil (comparative products 1-4) were superior in usability.

  In particular, the dentifrice of the present invention (invention products 5 and 6) using the rose petal extract and rose petal essential oil had a very excellent feeling of use.

  The dentifrice of the present invention can impart a high refreshing feeling or refreshing feeling to the oral cavity without causing bitterness or irritation.

Therefore, as a general dentifrice, a refreshing feeling and the like can be given even when the toothbrushing time becomes long as in the case of a dentifrice that does not substantially contain a surfactant.
