Derived from rosemary leaves, it enhances the stability and quality of cosmetic formulas. Its natural antioxidant properties help shield products from deterioration caused by exposure to oxygen, thereby prolonging their shelf life.
Fermented preservatives are a cutting-edge approach in the cosmetic industry, derived from the fermentation process of natural ingredients like fruits and plants. These preservatives prevent the growth of harmful microbes and enrich products with additional skin-friendly benefits. For example, lactobacillus ferment, a popular choice, offers antimicrobial properties while also soothing and hydrating the skin.
Vitamin E is a natural antioxidant that helps keep cosmetic products fresh for longer by preventing them from spoiling due to exposure to air or other reactive substances. This nutrient is not only beneficial for the skin but also helps maintain the freshness and efficacy of formulations. Its protective action against oxidation makes it a preferred choice for preserving products naturally.
Shifting from natural preservatives, being aware of certain preservatives to avoid due to its health risks or environmental impact is critical. Here are the preservatives that are often recommended to avoid:
Formaldehyde donors, though effective preservatives, release formaldehyde slowly which can be a skin irritant and allergen. This has led to increased worry among consumers and more attention from regulators due to its potential carcinogenic properties. To address this, many products now avoid these ingredients to meet the demand for safer alternatives.
Isothiazolinones, including methylisothiazolinone (MIT) and methylchloroisothiazolinone (CMIT), are synthetic preservatives known for their antimicrobial properties. Yet, they’ve been linked to skin sensitivity and allergies, urging individuals with sensitive skin to exercise caution. Regulatory bodies have restricted their use in some products, and businesses are seeking safer and less irritating alternatives.
Propylene Glycol is a synthetic liquid substance that absorbs water and is used as a solvent, skin-conditioning agent, and preservative in cosmetics. Although generally recognized as safe, it can cause skin irritation and allergic reactions in some individuals, especially those with sensitive or compromised skin barriers. Its use is becoming less common in products marketed as gentle or for sensitive skin.
Triclosan is an antimicrobial agent that was widely used in personal care products, like antibacterial soaps and toothpastes. However, worries about its effects on the environment, including its role in antibiotic resistance and hormone disruption in wildlife, have led to bans and restrictions in several countries. As a result, many companies are phasing out triclosan in favor of safer and more eco-friendly preservatives.
Adhering to industry standards is crucial for safe cosmetic preservatives, ensuring compliance with legal and ethical guidelines while avoiding harmful substances. Here are the key regulations to follow:
