Phenyl Propanol, Phenyl Ethyl Carbinol, Ethyl Benzyl Alcohol, 93-54-9

Phenyl Propanol, Phenyl Ethyl Carbinol, Ethyl Benzyl Alcohol, 93-54-9

PHENYLPROPANOL (1-PHENYL-1-PROPANOL)

1. PRODUCT DEFINITION AND CHEMICAL IDENTITY

Important Isomer Clarification: This document refers specifically to 1-Phenyl-1-propanol (CAS 93-54-9) , which is synonymous with α-ethylbenzyl alcohol and ethyl benzyl alcohol. This must not be confused with its structural isomer, 3-Phenyl-1-propanol (CAS 122-97-4), which has different physical and functional properties. The term "phenylpropanol" in the market may occasionally refer to either isomer; this TDS is specific to the 1-phenyl derivative.

Natural Origin: This chemical is of 100% natural origin; it is not a synthetic product. This is a key differentiator and makes it highly valuable in natural cosmetic and food formulations.

3. FUNCTIONAL PROPERTIES AND MODE OF ACTION

Phenylpropanol exhibits a unique dual functionality in formulations:

• Natural Preservative (Antimicrobial Agent): It demonstrates potent, broad-spectrum antimicrobial activity, especially in emulsion systems. It is effective against bacteria, yeasts, and moulds. A key technical advantage is its ability to remain effective at a high pH range, unlike many conventional preservatives (e.g., organic acids) which lose activity in alkaline conditions. This makes it ideal for preserving natural formulations with a high pH.

• Natural Fragrance and Flavour Component: It possesses a sweet, balsamic, floral aroma reminiscent of hyacinth. It is used to impart a natural fragrance to perfumes, cosmetics, and soaps, and to provide a balsamic, wine-like flavour to food and beverages. It can also effectively mask undesirable base odours in formulations.

• Skin Conditioning and Synergistic Activity: It is used in cosmetic formulations for skin-brightening applications (targeting dark spots) and for reducing fine lines and wrinkles, often in combination with active ingredients like Hyaluronic Acid. It also functions well in oil-control makeup setting sprays.

4. PRODUCTION

Phenylpropanol is produced from 100% natural raw materials. It is not a synthetic product, which is its most significant commercial and regulatory advantage.

• Storage:

  • Store in a cool (<25 °C), dry, and well-ventilated area in tightly sealed, original packaging.

  • Protect from direct sunlight and sources of ignition.

• Shelf Life: At least 24 months in unopened, original packaging under proper storage conditions.

• Personal Protection: Standard industrial hygiene practices (nitrile gloves, safety goggles) are recommended when handling large quantities.

9. FREQUENTLY ASKED QUESTIONS

Q1: Is "ethyl benzyl alcohol" the same as "phenylpropanol"?
Yes, for the specific isomer 1-Phenyl-1-propanol (CAS 93-54-9) . The names α-Ethylbenzyl alcohol, Ethyl benzyl alcohol, and 1-Phenyl-1-propanol are synonyms that describe the exact same chemical structure. However, it should not be confused with 3-Phenyl-1-propanol (CAS 122-97-4), which is a different structural isomer.

Q2: Why is phenylpropanol effective as a preservative at high pH?
Unlike common organic acid preservatives (like benzoic or sorbic acid) which are only active in their undissociated form at low pH, phenylpropanol's antimicrobial mechanism does not rely on acidity. It is an alcohol, and its mechanism is based on disrupting microbial cell membranes, which remains effective even in alkaline conditions. This is a crucial advantage for preserving natural formulations like soaps and some creams that have a high pH.

Q3: Is phenylpropanol fully natural?
Yes, this product is of 100% natural origin. It is produced from natural raw materials without synthetic steps, making it an excellent choice for certified natural and organic cosmetic and food products.

Q4: What is its main role in Vitamin C serums?
In Vitamin C (Ascorbic Acid) serums, it plays a dual role: it acts as a natural preservative to protect the water-based formula from microbial contamination, and it serves as a fragrance component to mask the sometimes unpleasant, metallic odour of the active ingredients.
