Understanding Preservatives in Skincare
Let’s start at the beginning.
Preservatives: what are they?
In essence, preservatives are ingredients added to beauty and personal care products to enhance their shelf-life.
If we dig a little deeper, these substances prevent or slow microbial growth, thereby protecting the product and the user from potential infections.
The Role of Preservatives in Preventing Microbial Contamination
Moulds, yeasts, bacteria – do not sound very pleasant, but don’t worry. This is where our hero (preservative) steps into action.
It combats these unwanted invaders ensuring your favourite skincare products stay safe for use longer than just a few days after opening.
Among the myriad of preservatives found in skincare products, a few notable ones, such as formaldehyde preservatives, methylisothiazolinone, methylchloroisothiazolinone, and parabens, tend to be more prevalent.
Formaldehyde preservatives are often selected for their affordability and their broad-spectrum activity against bacteria and viruses.
While the term “formaldehyde” may raise eyebrows due to its associations outside of cosmetics, it’s important to remember that the European Union closely regulates its usage in skincare, and it is considered safe at low concentrations.
Another pair of commonly used preservatives is methylisothiazolinone (MI) and methylchloroisothiazolinone (MCI).
These substances are known for their robust antimicrobial activity.
A few years ago, they gained notoriety as potential skin allergens in susceptible individuals. This prompted the EU to prohibit their use in leave-on cosmetics, such as face creams and wet wipes. However, they are still permitted in rinse-off products like shower gels at lower concentrations, where they are deemed safe.
Parabens, which have been in use since the 1950s, are another widely used class of preservatives.
These compounds have been scrutinised due to a now-discredited hypothesis linking them to breast cancer.
Despite the negative press, comprehensive research demonstrates that parabens are not toxic to human cells. They remain some of the safest preservatives in cosmetics today.
It’s crucial to note that while some of these ingredients may have faced criticism in the media, exhaustive scientific research and strict regulation uphold their safety in cosmetics. This rigorous vetting process ensures that these preservatives are safe for our skin, protecting our health and the efficacy of our skincare products.
The Necessity of Preservatives in Water-Based Products
Contrary to popular belief, not all skincare products require preservatives.
However, any product that contains water—a common ingredient in many cosmetics requires preservatives to prevent it from spoiling within a few days.
Water is a lifeline for many organisms, including those we’d rather not have on our skin.
Water serves as an excellent medium for microbial growth in the realm of skincare products. This includes bacteria and fungi that can cause health issues or spoil your favourite cream.
This is where preservatives step into the picture.
Studies show that any cosmetic product containing water needs a good dose of these protective ingredients to keep it fresh and safe from microbial contamination. Without them, your go-to moisturiser could become a breeding ground for harmful microbes within days.
Common Types of Preservatives Used
You may be familiar with some common preservative names like sodium benzoate, citric acid, or lactic acid present in various personal care products you use daily.
• Sodium Benzoate is derived from benzoic acid found naturally in fruits such as cranberries, prunes, and apples – all considered safe by EU cosmetics regulation guidelines when used at appropriate concentrations.
• Citric Acid: Extracted primarily from citrus fruits such as lemons & oranges – also widely considered safe.
• Lactic Acid: Found naturally occurring in sour milk but commercially produced via a fermentation process using cornflour or beet sugar – another ingredient deemed harmless under recommended usage levels according to EU regulations.
Debunking Myths About Synthetic Vs Natural Preservatives
In the modern skincare market, where ‘natural’ is often synonymous with ‘better,’ the demand for natural preservatives is rising.
However, natural preservatives are not always superior to synthetic counterparts, and the media’s vilification of artificial preservatives often leads to misconceptions.
While natural preservatives may sound appealing, they can present challenges such as lower antimicrobial activity, limited options, the necessity for high concentrations, potential skin sensitivity, and variation between product batches.
The rise in popularity of organic skincare products has fuelled an unfounded fear towards synthetic preservatives like parabens or imidazolidinyl urea. This is despite scientific evidence showing their safety at prescribed concentrations as per EU cosmetics regulations.
Despite the perception of natural alternatives being safer, this may not always be true.
Difficulties Associated with “Natural” Preservations
• Natural options may require higher concentrations to achieve similar efficacy, which can lead to skin irritation.
• Variations between product batches could also pose quality control issues.
• A worry that should not be disregarded when utilising these “natural” ingredients is the possible allergenicity over time.
Safety Concerns Around Skincare Product Preservation
Rest assured that regulations exist to ensure consumer safety when it comes to preservatives in skincare products.
The EU Cosmetics Regulation, for instance, ensures all chemicals applied to the skin are safe at prescribed concentrations.
This regulation mandates rigorous testing and evaluation before any cosmetic product hits the market. The law requires all components, be they manufactured preservatives like butylated hydroxyanisole and sodium benzoate or organic substances such as rosemary or grapefruit seed extract, to be safe for people when utilised in typical circumstances.
All ingredients must be considered safe for human health when used under normal conditions. This includes potential exposure scenarios like dermal contact, inhalation, or accidental ingestion.
Making Knowledge-Based Choices Over Fear-Driven Ones
We may be swayed by controversial ingredients and marketing hype rather than scientific facts, and fear can often cloud our judgement.
Preservatives in skincare products don’t have to be feared; they’re not the bad guys.
Science plays a pivotal role when choosing between ‘natural’ and ‘synthetic’. While appearing attractive on paper, natural preservatives such as grapefruit seed and rosemary extract can be harsh on the skin due to their high concentration levels.
Importance Of Science Backed Data When Choosing Between ‘Natural’ Vs ‘Synthetic’.
Synthetic preservatives such as sorbic acid and salicylic acid have been deemed safe according to EU cosmetics regulation standards. They effectively prevent microbial contamination without causing health issues associated with some natural alternatives.
This includes synthetic substances like imidazolidinyl urea, which is considered safe at regulated concentrations despite being a common preservative.
Studies have shown that synthetic options could be less likely to cause skin irritant reactions than essential oils used in organic skincare formulations.
So remember, make your choices based on knowledge, not fear.
