A silicone that helps to protect the skin by forming a water-repellent barrier against water soluble irritants.


Helps protect skin: Its thick, viscous nature, makes for an excellent barrier on the skin to help prevent chaffing, nappy rash and other forms of skin irritation caused by friction and exposure to water-soluble irritants.

Occlusive and moisturising: The ability of Dimethicone to form a barrier on the skin also makes it effective for use as an occlusive. Occlusives help prevent moisture in the skin from evaporating.

Products that contain Dimethicone

A humectant, helping to draw and hold water to the skin to maintain hydration.


Excellent skin moisturiser and conditioner: Moisturisers containing glycerin can produce long-lasting moisturisation by minimising water loss1.

Helps protect against irritation: 10% Glycerine in a topical emulsion can help prevent the irritation and dehydration effects of washing the skin, including when Sodium Lauryl Sulphate is used as the detergent2.

Helps to retain moisture in the skin: At high humidity, Glycerine acts as a humectant, while at low humidity it acts as a skin moisturiser and conditioner by inhibiting lipid phase transition2.

An emollient that helps to reduce moisture loss from the outermost layer of the skin to maintain hydration.


Safe for prolonged use: Critical analysis of studies into the toxicity of mineral oils such as Paraffinum Liquidum has shown that it is safe for prolonged use3.

Rarely causes allergic reactions: Allergic reactions to Paraffinum Liquidum are infrequent considering its widespread use in topical products4.

Non-comedogenic: Highly refined and purified mineral oils, such as Paraffinum Liquidum found in cosmetic and skincare products are non-comedogenic5 (does not clog pores).

Highly efficacious moisturising ingredient: Paraffinum liquidum keeps the skin moist and supple by providing a protective film and controlling the passage of water into and out of the skin6.

A highly effective emollient, used to promote both short- and long-term skin rehydration.


Contributes to skin barrier properties: It penetrates the uppermost stratum corneum layers, passing into the intercellular phase. Rather than integrating with the natural intercellular layer, it is distributed throughout the stratum corneum as a separate phase, thus contributing to the skin’s natural barrier properties7.

Reduces transepidermal water loss: The application of petroleum jelly to the skin in vivo can immediately reduce transepidermal water loss by 40-50%8.

Low irritancy rating: Widely recognised as being innocuous and non-allergenic9. Only rarely are sensitisation reactions reported10 and petrolatum presents few, if any, safety or toxicological problems11.

Naturally-occurring component of the skins oil (sebum), this emollient works as a vehicle to help carry other substances or ingredients across the skin.


Non-irritant: Usage levels range from 0.1% to greater than 50% and is a safe cosmetic ingredient as used in current practices and concentrations12.

Moisturising: Commonly used in topical preparations as an emollient13-14, lubricant and humectant13.
