Propylene Glycol Uses: What Is PG Used For?

Propylene Glycol is a versatile ingredient used across cosmetics and personal care and food formulations and fragrances and pharmaceutical products and commercial manufacturing.

Often shortened to PG, it is a clear and virtually odourless liquid that can perform several different roles depending on the formulation.

So what exactly is Propylene Glycol used for?

Here are some of the most common Propylene Glycol uses and why PG has become such a widely used ingredient.

What Is Propylene Glycol?

Propylene Glycol is a clear liquid also known as propane 1,2 diol. Compared with Vegetable Glycerine it has a much thinner consistency. PG is commonly used as a carrier, solvent and humectant which makes it valuable within many different types of products. The exact role it performs depends on the formulation and the grade being used.

Propylene Glycol in Cosmetics and Personal Care

Cosmetics and personal care are among the most common uses for Propylene Glycol.

PG can help carry or dissolve other ingredients within a formulation while also helping retain moisture.

It may be found within products such as:

  • Moisturisers

  • Creams

  • Lotions

  • Serums

  • Shampoos

  • Conditioners

  • Body washes

  • Deodorants

  • Cosmetic formulations

The amount required depends entirely on the product and formulation.

Propylene Glycol in Food and Flavour Applications

Food grade Propylene Glycol can also be used within certain food and flavour applications. Propylene Glycol is identified as E1520 when used as an authorised food additive. One of its useful properties is its ability to act as a carrier or solvent for other ingredients.

Possible applications include:

  • Flavourings

  • Food formulations

  • Colouring preparations

  • Ingredient carrier systems

  • Specialist food production

As with any food ingredient the correct grade must be selected and the requirements of the individual application should always be followed.

Propylene Glycol in Fragrances

Propylene Glycol can also be used within fragrance and scented product formulations.

Its ability to carry and dissolve certain ingredients makes it useful within products where fragrances or other components need to be distributed throughout a liquid formulation.

Applications can include:

  • Fragrance formulations

  • Air fresheners

  • Personal care products

  • Scented household products

The amount of PG used will depend on the individual formula.

Propylene Glycol in Household and Technical Products

PG is not limited to food and personal care.

It is also used across a variety of household and technical applications.

These can include:

  • Cleaning formulations

  • Specialist liquids

  • Solvent systems

  • Household products

  • Commercial formulations

  • Technical applications

Its versatility is one of the main reasons Propylene Glycol is used across so many different industries.

Propylene Glycol in Pharmaceutical and Laboratory Applications

High purity Propylene Glycol is also widely used within pharmaceutical and laboratory environments.

Depending on the required specification it may be used as a carrier or solvent within products such as:

  • Liquid formulations

  • Creams

  • Gels

  • Topical products

  • Laboratory formulations

  • Pharmaceutical preparations

For specialist applications the exact grade and specification of Propylene Glycol should always be checked before use.

What Is the Difference Between PG and VG?

Propylene Glycol and Vegetable Glycerine are both clear liquids but they have noticeably different characteristics.

PG is thinner while VG is considerably thicker.

VG is particularly well known for its moisture retaining properties while PG is commonly valued as a solvent and carrier.

This means the best option depends entirely on what you are creating.

Some formulations use one ingredient while others may use both.
