PEG is a common ingredient in some of the formulas of toothpastes; it is a hydrophilic polymer that acts as a dispersant in toothpastes. Also, it is used in many cosmetic and pharmaceutical formulas, for example: ointments, osmotic laxatives, some of the nonsteroidal anti-inflammatory drugs, other medications and household products. [61] However, 37 cases of PEG hypersensitivity (delayed and immediate) to PEG-containing substances have been reported since 1977, [62] suggesting that they have unrecognized allergenic potential. [62] Miscellaneous issues and debates [ edit ] Jāsön [23] offers toothpaste among a variety of other personal care products. Jāsön is a brand of Hain Celestial. [24] Since 5000 BC, the Egyptians made a tooth powder, which consisted of powdered ashes of ox hooves, myrrh, powdered and burnt eggshells, and pumice. The Greeks, and then the Romans, improved the recipes by adding abrasives such as crushed bones and oyster shells. [78] In the 9th century, Iraqi musician and fashion designer Ziryab invented a type of toothpaste, which he popularized throughout Islamic Spain. The exact ingredients of this toothpaste are unknown, but it was reported to have been both "functional and pleasant to taste". [79] It is not known whether these early toothpastes were used alone, were to be rubbed onto the teeth with rags, or were to be used with early toothbrushes, such as neem-tree twigs and miswak. During Japan's Edo period, inventor Hiraga Gennai's Hika rakuyo (1769) contained advertisements for Sosekiko, a "toothpaste in a box." [80] Toothpastes or powders came into general use in the 19th century. With the exception of toothpaste intended to be used on pets such as dogs and cats, and toothpaste used by astronauts, most toothpaste is not intended to be swallowed, and doing so may cause nausea or diarrhea. Tartar fighting toothpastes have been debated. [63] Sodium lauryl sulfate (SLS) has been proposed to increase the frequency of mouth ulcers in some people, as it can dry out the protective layer of oral tissues, causing the underlying tissues to become damaged. [64] In studies conducted by the university of Oslo on recurrent aphthous ulcers, it was found that SLS has a denaturing effect on the oral mucin layer, with high affinity for proteins, thereby increasing epithelial permeability. [65] In a double-blind cross-over study, a significantly higher frequency of aphthous ulcers was demonstrated when patients brushed with an SLS-containing versus a detergent-free toothpaste. Also patients with Oral Lichen Planus who avoided SLS-containing toothpaste benefited. [66] [67] Alteration of taste perception [ edit ]Zubne paste– kozmetika i higijena".

In 2016, Colgate-Palmolive was granted a patent (USPTO U.S. Patent 20,160,228,347) for suitable sorts of differently colored toothpastes to be filled directly into tubes to produce a striped mix without any separate compartments. This required adjustment of the diffent components' behavior ( rheology) so that stripes are produced when the tube is squeezed. [76] Even if the theory about color codes turned out to be true, it wouldn’t really make sense. Everything – including natural ingredients – is made out of chemicals, and the word “medicine” is too vague to really mean anything.

Sozodont: [38] a popular brand of oral hygiene product from the mid-nineteenth century to the early twentieth century. According to an 1889 issue of the journal American Druggist, Sozodont was made from a liquid and powder mixture. The powder contained orris root, carbonate of calcium, and magnesia. The liquid contained castile soap (soap made exclusively from vegetable oil), glycerin, sizable portions of water and alcohol, and, for flavoring, a small quantity of oil of peppermint, clover, cinnamon, and star anise, as well as, for coloring, cochineal (a dye made from an insect of the same name). [39] Marraffino's design, which remains in use for single-color stripes, is simple. The main material, usually white, sits at the crimp end of the toothpaste tube and makes up most of its bulk. A thin pipe, through which that carrier material will flow, descends from the nozzle to it. The stripe-material (this was red in Stripe) fills the gap between the carrier material and the top of the tube. The two materials are not in separate compartments, but they are sufficiently viscous that they will not mix. When pressure is applied to the toothpaste tube, the main material squeezes down the thin pipe to the nozzle. Simultaneously, the pressure applied to the main material causes pressure to be forwarded to the stripe material, which thereby issues out through small holes (in the side of the pipe) onto the main carrier material as it is passing those holes.
