Our ingredients

All our ingredients adhere to Solid’s core values of effectiveness and sustainability.

Ingredients you won’t find in Solid products

SLS; palm oil; animal or animal derived products; sugar; gluten; stevia. We don’t use flavour-of-the-month ingredients like charcoal. These are often misleading to customers and potentially detrimental to teeth

Some of our star ingredients

Calcium carbonate is a naturally occurring mineral. It is used as a gentle abrasive to polish the teeth and remove plaque. Calcium carbonate has a rating of 3 on the MOHS scale of mineral hardness (dental enamel is 5). We use our own blend of fine particle size calcium carbonate to clean effectively without causing dental abrasion.

Xylitol is a natural sweetener made from birch bark and corn cobs. Xylitol has a sweet taste, but cannot cause tooth decay. It has the ability to prevent oral bacteria from attaching to surfaces such as the teeth and tongue. It promotes the remineralisation of teeth by increasing saliva production, and significantly reduces plaque formation on the teeth (that fuzzy feeling).

Sodium monofluorophosphate (fluoride). We use fluoride in our toothpaste and toothpaste tablets because topical fluoride is the gold standard for strengthening teeth and preventing tooth decay. Fluoride is naturally present in minerals like fluorite, and also naturally occurs in water on earth. Brushing twice a day with fluoride toothpaste makes teeth significantly harder and more resistant to plaque acids. Our toothpaste, toothpaste tablets and toothpaste powders contain 1000ppm (parts per million) fluoride, which is the recommended strength for adults and children, based on many years of research (source: https://www.health.govt.nz/our-work/preventative-health-wellness/fluoride-and-oral-health).

Other useful ingredients

Flavour oil. Gives the product taste to help us to want to brush. Toothpaste without flavour will taste like soap + chalk 🙂 We blend our own flavours using natural peppermint oil, spearmint oil, cinnamon oil, orange oil, and more.

Coconut oil is used as a softening agent and flavour enhancer for our toothpaste tablets and toothpaste. It may also have a mild antibacterial activity. Our coconut oil is made from coconuts sustainably harvested from the Pacific Islands. It is used at a low concentration, so there is no danger of our toothpaste contributing to fatbergs in drains.

Glycerin is a safe and widely used humectant/moisturiser. Our glycerin is palm-free, so doesn’t contribute to deforestation.

Hydroxyethyl cellulose is a plant based gum that helps give our toothpaste the correct consistency.

Acacia gum is a plant based gum that helps to hold our toothpaste tablets together. There are studies that show acacia gum enhances the remineralisation of teeth.

Menthol. Our menthol is naturally derived from mint, and is responsible for that fresh, cool feeling we get after brushing.

Monk fruit is a sweet tasting fruit that contains powerful antioxidants called mogrosides. Studies have shown monk fruit can inhibit the growth of oral bacteria that cause tooth decay and periodontal disease.

Hydrogen peroxide can be thought of as liquid oxygen. It is a natural substance which can be found in trace amounts in rain and snow. Dilute hydrogen peroxide is a strong and safe antibacterial. After activation it converts into water and oxygen, making it a very environmentally friendly ingredient.

Flavour oil. Gives the product taste to help us to want to brush! Includes a good lashing of natural peppermint oils and spearmint oils.

Polysorbate 20 is a safe and widely used solubiliser. It allows us to disperse our mint flavour oil into a water based mouthwash.

Potassium nitrate is used in our sensitive toothpaste, and in the majority of sensitive toothpastes on the market. Multiple studies have shown this ingredient may block pain messages in the tooth nerve from reaching the brain, effectively reducing sensitivity.

Water. Steam distilled tap water, not bottled distilled water.

Sodium bicarbonate (baking soda) has a deodorising action. We use baking soda at a low level in our toothpaste and toothpaste tablets to increase the pH. A alkaline oral environment is helpful in preventing tooth decay. Baking soda often gets a bad rap as being abrasive to teeth, but there is no scientific evidence showing this is true.

Sodium citrate is the sodium salt of citric acid and occurs naturally in citrus fruits. We use sodium citrate as a stabiliser and pH adjuster in our mouthwash.

Sodium lauroyl sarcosinate is an extremely mild cleaning and foaming agent. We use sodium lauroyl sarcosinate instead of sodium lauryl sulfate (SLS), as there is evidence that SLS may delay the healing of aphthous ulcers in the mouth (otherwise known as mouth ulcers or canker sores). Our SLSarc is palm free.
