PHENETYL ALCOHOL

PHENETYL ALCOHOL: alternative to synthetic preservatives

EXCIPIENT ⎪CONSERVATIVE

What is Phenethyl Alcohol?

Thephenethyl alcohol is a natural or synthetic aromatic compound, used in cosmetics mainly as a mild preservative and as a perfumery agent. Naturally present in certain flowers, such as rose or neroli, this alcohol has a subtle and pleasant floral scent. In cosmetics, it is appreciated for its antimicrobial properties which help protect formulations against the proliferation of bacteria and yeasts. It is often used as a replacement for more aggressive preservatives, such as parabens. Phenethyl alcohol is well tolerated and fits perfectly into natural or organic formulations.

In our moisturizing perfecting emulsion, phenethyl alcohol plays the role of marine postbiotic preservative. It is a natural and safer alternative to traditional synthetic preservatives. Indeed, it is of natural origin and has effective antimicrobial properties. 

Where does Phenethyl Alcohol come from?

Phenethyl alcohol can be obtained from two main sources:

  1. Natural sources : It is extracted from flowers and plants such as rose, neroli or geranium. This process is often used in organic or luxury formulations to guarantee a natural origin.
  2. Chemical synthesis : It is manufactured in the laboratory to reproduce the natural molecule at a more accessible cost. This process guarantees consistent quality and optimal compatibility with cosmetic formulations.

Whether its origin is natural or synthetic, phenethyl alcohol is environmentally friendly, biodegradable and compatible with sustainable formulation standards.

Properties and active ingredients

Phenethyl alcohol offers several beneficial properties, both for formulations and for the skin. Here are its main characteristics and actions:

  1. Antimicrobial preservative : It limits the proliferation of bacteria, yeasts and molds in cosmetic products.
  2. Natural fragrance : It brings a subtle floral note which improves the sensory experience of the products.
  3. Gentle alternative to classic preservatives : It is often used in natural formulations to replace more aggressive preservatives.
  4. Universal Compatibility : It integrates easily into aqueous and oily formulations without affecting their texture or effectiveness.
  5. High tolerance : Non-irritating, it is well suited to sensitive skin.

What are the benefits of phenethyl alcohol?

Phenethyl alcohol offers many benefits, both for formulations and for the skin, thanks to its preservative and perfuming properties. Here are the main benefits of this ingredient:

  1. Protects formulations : It extends the life of products by preventing the growth of microorganisms.
  2. Natural and pleasant fragrance : Its sweet floral scent improves the sensoriality of the products without requiring additional addition of perfumes.
  3. Suitable for sensitive skin : Its softness makes it an ideal choice for hypoallergenic products or products intended for delicate skin.
  4. Respect the environment : Biodegradable and often from natural sources, it is included in eco-responsible formulations.
  5. Versatile : It is used in a wide range of cosmetic products, from creams to deodorants, shampoos and perfumes.

How to consume Phenethyl Alcohol?

Phenethyl alcohol is used topically in many care and hygiene products, particularly for its preservative and olfactory properties. Here are the main ways to benefit from this ingredient:

  • Face and body care : Present in moisturizing creams and lotions, it protects formulations and improves their fragrance.
  • Hair products : In shampoos and conditioners, it acts as a preservative and contributes to a pleasant smell.
  • Deodorants : It is used for its natural antimicrobial properties, limiting the proliferation of bacteria responsible for odors.
  • Perfumes and toilet waters : As a heart or base note, it adds a subtle floral dimension.
  • Mild Cleansers : In cleansing gels or micellar waters, it protects against contamination while respecting the skin.

Note : Phenethyl alcohol is generally well tolerated, but its concentration in products must respect regulatory thresholds to avoid any risk of irritation.

Any side effects?

Although phenethyl alcohol is generally considered safe, a few side effects may occur in rare cases:

  1. Allergic reactions : Individual hypersensitivity may cause redness or itching. A skin test is recommended before use on sensitive skin.
  2. Irritation at high concentration : Used in excess, it can cause slight irritation, especially on very reactive skin.
  3. Dehydrating effect : Although rare, it can, in certain poorly balanced formulations, cause a slight feeling of dryness.
  4. Interaction with other ingredients : It may lose its effectiveness in the presence of certain very acidic or alkaline active ingredients.
  5. Unsustainable synthetic origin : Some synthetic phenethyl alcohol may not be environmentally friendly. Favor certified products.

Sources

The use of phenethyl alcohol in cosmetics is well documented in conservation and perfumery research. It is recognized for its dual role as a gentle preservative and subtle floral fragrance. Studies show that it is particularly suitable for natural and organic formulations, thanks to its biodegradability and antimicrobial effectiveness. Its natural origin, extracted from plants such as rose, makes it a preferred choice for high-end, health-friendly products.
