Generalities: Toothpaste and Mouthwash are ideal delivery systems for active ingredients that promote and maintain oral health. Using toothpaste when brushing and mouthwash when swishing delivers various oral care benefits like prevention of caries, enamel erosion and bad breath, reducing gingivitis or tartar build-up, lessening dentin hypersensitivity. Oral Care innovation for superior efficacy is extremely important nowadays because of increased consumer desire for better oral hygiene.

Technical Challenges: Toothpaste formulation might contain multiple excipients that work in synergy and complement each other. These active ingredients can impact hedonics and mouth sensation and therefore consumer usage behavior. Along with efficacy taste is another important attribute of oral care products because it is directly linked to consumer preference and adherence to regimen.
Technical Challenges: Compositions comprising Clorhexidine, Zinc Oxide, Zinc Citrate, Stannous Fluoride, CPC, Peroxide to name a few, are highly efficacious and provide a wide range of benefits. However these ingredients present taste challenges as they impart undesirable off-notes to the toothpaste or mouthwash base. Also, some of these ingredients contain functional groups that can possibly interact with flavor molecules, therefore causes flavor instability.

Mint Oil : A love history The word mint is derived from the Latin : Mentha. Legend has it that Pluto s wife Proserpina cast a spell on a lovely young lady who had turned Pluto s eye, and turned her into a mint plant.

US Mint Oil Growing Areas Available growing land for mint in North America has become more and more limited over the last few years Main factors : competing crops and population increase Less land available has driven up pricing and limited the use of these oils Growing regions are located above the 41 st parallel where the climatic conditions (length of daylight) produces higher yield and quality oil
Plant disease is always a big threat Mint growing challenges Each year the farmers plant their mint from certified rootstock Rootstock is GMO free The mint crop is rotated out with other crops every 3 4 years due to soil conditions, but cannot be replanted for 11 years Poor soil conditions can result in low quality and yield of mint oil
Main Mint Varieties for Oral Care Flavors Over 600 varieties are known and almost all mints are hybrids. 2 main varieties are largely used in oral care: Peppermint : Mint containing Menthol Mint Arvensis Mint Piperita Spearmint : Mint containing Carvone

Mint Arvensis Menthol extraction Mint Arvensis is the primary source of natural Menthol => the crude oil is generally treated to extract Menthol The level of Menthol depends on climatic conditions (it is higher in tropical regions) Various Arvensis Mint qualities are obtained from different oil treatments : -Mint Arvensis DMO (partially dementholized oil) -Rectified Mint -Terpenless Mint Treatment improve the quality of the oil -Earthy / green note of Arvensis is removed -Terpenes are removed
Mint Arvensis
Mint Piperita Botanical name : Mentha Piperita Synonyms : Peppermint, Brandy Mint Part Used : Plant Culture No plantation every year. Roots stay in the ground for 3 to 5 years Single cut harvest (from August to early September) or double cut harvest (July and then late September) Fertile deep soil rich in humus with good water holding Warm days (25-30 C) and cool nights (15 C)
Mint Piperita

Roots stay in the ground for 3 to 5 years Double cut harvest (July and then late September) Warm days (25-30 C) and cool nights (15 C). Spearmint resist better to heat than mint piperita Fertile deep soil rich in humus with good water holding
Spearmint
Non Mint Ingredients There are two non Mint derived ingredients that are largely used in the development of Oral Care flavors : Wintergreen : Containing Methyl Salicylate Eucalyptus : Containing Eucalyptol (also known as cineol)
Spice Essential Oils Cinnamon Clove Anise Vanilla Mostly used at low levels for body and warmth Polarizing at high levels
