What are propellants in cosmetics?

Propellants give the pressure in an aerosol spray can (deodorants, shaving foams …), expelling what is called the active product when the valve is opened. Some liquefied propellants can act as solvents.

What is aerosol in cosmetics?

Aerosols are scientifically defined as a colloid of fine, solid particles or liquid droplets in air or another gas; a definition that includes human-made products but also natural phenomena like fog.

Why LPG is used in aerosol?

LPG is an odourless, non-corrosive and non-toxic gas. The propellant is made up of natural compounds. LPG offers a wide range of applicable vapour pressures and boiling points. LPG is a versatile and efficient propellant.

Why is propane in Hairspray?

Butane, Isobutane, Propane and Isopentane are volatile substances derived from petroleum and natural gas. These ingredients are used in cosmetics and personal care products as a replacements for chlorofluorocarbons, or CFC propellants, some of which have been shown to have negative effects on the environment.

What products are aerosol?

Aerosols are used for more cosmetic products than just the common hair and body sprays. Gel toothpastes, cream foundations, lotions and hydrating creams, self-tanners, sunscreen, thermal waters and makeup setting sprays are just a few of many personal care items that use aerosols.

What are the types of propellants?

Liquid propellants used in rocketry can be classified into three types: petroleum, cryogens, and hypergols. Petroleum fuels are those refined from crude oil and are a mixture of complex hydrocarbons, i.e. organic compounds containing only carbon and hydrogen.

What is the propellant in deodorant?

For example, isobutane, a propellant in aerosol sprays, can be contaminated with carcinogenic butadiene. Aerosol sprays create extremely small particles, which can be more deeply inhaled and this may increase their harmful effects.

What are the different types of aerosols?

The five most common classifications of aerosols are dust, fume, mist, smoke, and fog. Generally, dust describes large, solid aerosols. Fumes are small, liquid aerosols.

Is LPG an aerosol?

The main industry where LPG in its natural odourless form is required is in fact the aerosol industry, where it is considered an ideal ‘propellant’. Aerosol propellant grade LPG consists of high purity hydrocarbons derived directly from oil wells, and as a by-product from the petroleum industry.
