Propylene glycol is a synthetic liquid substance that is used as a chemical solvent and an antifreeze agent in various industries.

Definition And Uses

Understanding the role and uses of propylene glycol is essential, especially given its presence in various industries such as pharmaceuticals, cosmetics, and food products.

As an FDA-approved synthetic substance, propylene glycol serves multiple purposes. Notably, it acts as a solvent for natural flavors derived from non-GMO plants and food colors.

In terms of consumption within alcoholic beverages, propylene glycol can be found acting as a stabilizer to improve taste and texture while also ensuring the drink’s longevity on store shelves.

Despite these regulatory approvals for use in alcohol production processes, this substance has been surrounded by controversy due to potential health risks associated with prolonged exposure or consumption.

FDA Regulations

The FDA has established specific guidelines and requirements for substances used in food, beverage, and pharmaceutical industries. Among these regulated substances is propylene glycol, a synthetic compound commonly utilized as a solvent or emulsifying agent in various products.

In the case of Hint Water, an important aspect to consider is the addition of natural flavors derived from non-GMO plants. The manufacturing process may involve using solvents like propylene glycol within permissible levels outlined by FDA guidelines.

The Controversy Surrounding Hint Water And Propylene Glycol

Hint Water is facing a lawsuit over its use of propylene glycol, a synthetic liquid substance that is causing concerns about the safety of consuming “natural flavors.” Read on to learn what’s behind the controversy and whether there are any health risks associated with drinking Hint Water.

Overview Of The Lawsuit

In the world of all-natural products, marketing claims and ingredient listings play a significant role in shaping consumers’ decisions. A class action lawsuit was filed against Hint Water, alleging that their “all-natural” label is deceptive due to the presence of propylene glycol, a synthetic ingredient.

Propylene glycol came into focus when independent testing reportedly found it as part of Hint Water’s “natural flavors”.

Interestingly enough, Hint Water isn’t the only brand caught up in this controversy; Zico has also faced a similar legal battle over its use of propylene glycol. These lawsuits bring attention to issues like consumer deception and false advertising within the food and drink industry.

Claims And Counterclaims About Propylene Glycol In Hint Water

There has been a lot of controversy surrounding Hint Water and its use of propylene glycol. In 2017, the company was hit with a class-action lawsuit claiming that their “natural flavors” contained this synthetic ingredient, which is not listed on the label.

This sparked concerns among consumers who were under the impression that Hint Water was an all-natural beverage option.

However, there are counterclaims defending Hint Water’s use of propylene glycol in their products. Impax Laboratories Inc., which manufactures Hint Water, states that they have justifications for using this ingredient based on FDA regulations and scientific studies.

Despite these claims, many people still view propylene glycol as a potentially harmful ingredient due to allergic reactions, respiratory issues, and skin irritation in some individuals.

Definition Of ‘Natural’ And ‘Natural Flavor’

The term ‘natural’ is often used to suggest that a food or drink is healthier and has fewer artificial ingredients. However, the Food and Drug Administration (FDA) has not legally defined what qualifies as ‘natural,’ leaving it open to interpretation by manufacturers.

On ingredient labels, the term ‘natural flavor’ refers to any flavoring substance obtained from plant or animal sources, including fruit extracts, essential oils or spices.

This means that even though something may be labeled as natural flavoring, it can still contain synthetic chemicals such as propylene glycol.

Let’s dive into the analysis of ingredient labels and lawsuit claims to find out whether Hint Water contains propylene glycol – you won’t want to miss what we uncovered.

Analysis Of Ingredient Labels And Lawsuit Claims

As the controversy around Hint Water’s use of propylene glycol continues, many are questioning if this is outlined in the ingredient labels and how it was discovered.

The 2017 lawsuit against Hint Water for not being “all-natural” brought attention to this issue, but a recent 2021 lawsuit further claims that the company has been deceptive about their ingredient list.

The misleading marketing used by Hint Water also raises concerns about consumer deception and trust. With all-natural labeling regulations not clearly defined by the FDA, companies may be able to get away with using synthetic ingredients without disclosing them in their labels or marketing materials.

In conclusion, analysis of both the Ingredient Labels and Lawsuit Claims surrounding Hint Water reveals significant questions regarding transparency from product manufacturers around so-called natural flavoring additives like Propylene Glycol.

Research Findings

Research has found that Hint Water’s “natural flavor” does contain propylene glycol, a processed ingredient also used in antifreeze. In the lawsuit against the company over their use of this ingredient, it was argued that propylene glycol is not considered “natural” and should not be listed as such on product labels.

As someone dealing with alcoholism, it’s essential to pay attention to what goes into our bodies and how it can affect us. Propylene glycol consumption can lead to respiratory issues, skin irritation and even allergic reactions for some people.

It’s important to note that while Hint Water contains zero-calorie sugar-free artificial sweeteners like Stevia or Erythritol instead of traditional sugars, consumers need to understand all the additives involved in creating these beverages.

Health Implications Of Propylene Glycol Consumption

Consuming propylene glycol may cause allergic reactions, respiratory issues, and skin irritation.

Allergic Reactions

For those with propylene glycol allergies, consuming Hint Water can lead to mild to severe allergic reactions. Symptoms of an allergic reaction may include a rash on the face or body, itching, hives, and swelling.

It’s important to note that only between 0.8% to 3.5% of people are allergic to propylene glycol.

Respiratory Issues

Consuming propylene glycol, an ingredient sometimes found in food and beverages, may cause respiratory issues for some individuals. These can include coughing, wheezing, shortness of breath, and chest tightness.

In addition to respiratory issues, exposure to high levels of propylene glycol through inhalation or ingestion can lead to skin irritation and eye irritation.

It is important to note that while there have been claims made about more severe health risks associated with propylene glycol consumption such as heart attacks, kidney and liver failure, and brain problems these claims have not been substantiated by scientific research.

Skin Irritation

Propylene glycol consumption has been linked to skin irritation and possible eczematous reactions, making it an important ingredient to be aware of in cosmetics and food products.

Hint Water is currently facing a lawsuit over its use of propylene glycol, with allegations that their products are falsely marketed as “all-natural.” The safety of consuming propylene glycol as a food additive is debatable, with concerns about potential health risks.

It’s important to understand the ingredients in the products we consume and how they can impact our body, especially when it comes to sensitive skin or allergies.

Potential Risks And Side Effects

Propylene glycol is a food additive that is generally considered safe for consumption by the FDA. However, it can cause some short-term side effects such as nausea, vomiting, headache, dizziness, and lightheadedness.

While most studies suggest that propylene glycol is safe when consumed in small quantities as a food additive, there are claims that it can lead to more severe health conditions like kidney and liver failure or brain problems.

It’s important to remember that everyone has different sensitivities to various substances; while some people may be able to safely consume propylene glycol with no ill effects, others may experience severe allergic reactions or respiratory issues after being exposed to even small amounts.


In conclusion, the controversy surrounding propylene glycol in Hint Water has caused concern among consumers. However, after analyzing the ingredients and research findings, it appears that Hint Water does not contain this synthetic substance.

The natural flavors used in Hint Water have undergone a flavoring process that involves using solvents such as propylene glycol, but these are incidental and do not pose any significant health risks.

It is important to note that processed foods and drinks often include additives like preservatives or artificial sweeteners. but Hint Water prides itself on being a clean label product for those seeking a healthier alternative with transparent ingredient labeling.
