The present invention relates to antimicrobial oral compositions comprising a water-soluble zinc salt wherein a surfactant selected from alkali metal or ammonium salts of alkyl sulfoacetate, dialkyl sulfosuccinate, dialkyl sulfosuccinamate; and mixtures thereof; is used in an amount effective to reduce the astringency of the zinc salt.
The present invention relates to an oral composition comprising, in an orally acceptable carrier, from 0.1% to 5% zinc oxide; and from 0.1% to 5% of a source of carbonate ions selected from alkali metal and ammonium carbonates and bicarbonates. The molar ratio of carbonate ion to zinc ion is from 0.05:1 to 1:1. The composition has good antiplaque efficacy and taste. Preferred compositions are toothpastes.
The present invention relates to a dentifrice composition comprising:
a) a polyphosphate salt in particulate form, the polyphosphate salt comprising a polyphosphate anion comprising at least 10 phosphate units; and
b) an orally acceptable carrier;
characterised in that the polyphosphate salt has a particle size distribution wherein less than 10% by volume of the salt has a particle size of greater than 160 µm and less than 20% by volume of the salt has a particle size of less than 20 µm. The dentifrice composition has good stability and acceptable mouth feel.
The invention further relates to orally acceptable polyphosphate salts for use in such compositions.
本发明涉及一种牙膏组合物,该组合物包括
a) 颗粒状的聚磷酸盐,聚磷酸盐包括至少 10 个磷酸单位的聚磷酸盐阴离子;和
b) 口服可接受的载体;
其特征在于,聚磷酸盐的粒度分布为:按体积计算,小于 10%的盐的粒度大于 160 微米,小于 20%的盐的粒度小于 20 微米。该牙膏组合物具有良好的稳定性和可接受的口感。
本发明还涉及用于此类组合物的口服可接受的聚磷酸盐。

The present invention relates to an aqueous oral composition comprising:
a) from 0.2% to 3% divalent metal ions comprising:
i. from 0.1% to 1.5% of zinc ions;
ii. from 0.1% to 2% oftin (II) ions; and
b) a source of fluoride ions;
c) a silica dental abrasive;
d) one or more chelants having a MW of less than 1000 and capable of forming water-soluble complexes with the zinc ions, wherein the chelants comprise less than 0.2% linear polyphosphates having a chain length of four or more;
e) an orally acceptable carrier comprising at least 20% total water;
wherein the pH of the composition is from 5 to 6.5, the molar ratio of the chelants to the divalent metal ions is at least 0.70:1 and at least 80% by weight of the total zinc ions are solubilised within the composition.
The composition of the invention has been found to give improved antimicrobial activity from the zinc / stannous combination without significant taste, staining or stability problems, compared to compositions having lower levels of chelants.
本发明涉及一种含水口服组合物,该组合物包括
a) 0.2%至 3%的二价金属离子,包括
i. 0.1%至 1.5%的锌离子;
二. 0.1%至 2%的锡(II)离子;以及
b) 氟化离子源;
c) 二氧化硅牙科研磨剂;
d) 一种或多种螯合剂,其分子量小于 1000,并能与锌离子形成水溶性复合物, 其中螯合剂包括小于 0.2%的线性多磷酸盐,其链长为 4 或更长;
e) 一种口服可接受的载体,包含至少 20%的总水;
其中,组合物的 pH 值为 5 至 6.5,螯合剂与二价金属离子的摩尔比至少为 0.70:1,且总锌离子重量的至少 80%溶解在组合物中。
与螯合剂含量较低的组合物相比,本发明的组合物可以提高锌/亚锡组合的抗菌活性,而不会产生明显的味道、染色或稳定性问题。

The present invention relates to a single phase oral care composition comprising:
a. a stannous salt
b. a potassium salt
c. a chelant
d. less than 0.01% sodium lauryl sulphate
wherein the oral care composition provides a soluble fluoride ion level of greater than 50% of the total fluoride ion.
The composition of the invention has been found to allow prolonged contact between stannous ion and nitrate ion in a single dentifrice without toxic effects or insoluble products. The invention further provides for the maintenance of an efficacious fluoride ion level.
本发明涉及一种单相口腔护理组合物,包括
a. 锡盐
b. 一种钾盐
c. 一种螯合剂
d. 低于 0.01%的十二烷基硫酸钠
其中,口腔护理组合物提供的可溶性氟离子含量大于氟离子总量的 50%。
研究发现,本发明的组合物允许亚锡离子和硝酸根离子在单一牙膏中长时间接触,而不会产生毒性影响或不溶产物。本发明还提供了维持有效氟离子水平的方法。
