# Laboratory determination of Caprylyl glycol (CAS n° 1117-86-8)

## Do you want to measure the Caprylyl glycol present in your cosmetic products in accordance with current regulations?

### What is Caprylyl glycol?

Caprylyl glycol (or 1,2 Octanediol) is used as an **emulsifier** in skin care products. It promotes the bonding of water and oil, improving the structure of the skin care product. Its ability to limit the proliferation of microbes makes it a widely used [**preservative**](https://filab.fr/en/sectors-of-activity/laboratory-analysis-cosmetics/laboratory-analysis-preservatives-cosmetic.md) in a wide variety of [cosmetic products](https://filab.fr/en/sectors-of-activity/laboratory-analysis-cosmetics.md). Caprylic acid comes from palm oil, coconut oil or mammalian milk. A naturally occurring ingredient, it appears as a clear, colourless liquid.

### Why measure Caprylyl glycol?

Caprylyl glycol is widely accepted and used in cosmetic formulations, but manufacturers are required to comply with current regulations. In Europe, caprylyl glycol is regulated by [EC Regulation No. 1223/2009. ](https://eur-lex.europa.eu/legal-content/FR/ALL/?uri=celex%3A32009R1223#)

### What are the properties of Caprylyl glycol?

  [Preservative](https://filab.fr/en/sectors-of-activity/laboratory-analysis-cosmetics/laboratory-analysis-preservatives-cosmetic.md): often used in combination with another preservative Texturising agent: makes cosmetics easy and pleasant to use Emollient agent: softens and smoothes the skin Humectant agent: helps retain moisture in the skin
