“Direct isododecane-specific skin efficacy data are limited; CIR review supports its cosmetic role as a solvent/emollient isoparaffin with reviewed skin safety at current use levels.”
Isododecane (Germany)
Cosmetics
Code: 228
Ultra-lightweight Emollient Can quickly evaporate from the skin. Makes it not leave a sticky residue on the skin. and is soluble in silicones, hydrocarbons, isoparaffin without soluble in water. Suitable for use in place of oil in oil-free formulas that require extra lightness.
Isododecane is an ultra-lightweight Emollient. Can quickly evaporate from the skin. Does not clog pores Makes it not leave a sticky residue on the skin. and is soluble in silicones, hydrocarbons, isoparaffin without soluble in water. Suitable for use in place of oil in oil-free formulas that require extra lightness. and prevents a sticky feeling on the skin including protection against water (water-repellent) such as Vitamin C Anhydrous, Mascara, various makeup products
If volatile emollient is not required, please select Isohexadecane instead, which will have a soft, smooth, light and similar properties. but cannot evaporate
Comparison of 3 types of hydrocarbons emollient:
1. Isododecane lightest weight can volatilize It helps to blend the formula well.
The company sells Isododecane 2 grades : Isododecane (Germany) and Isododecane (Japan)
2. Isohexadecane have more weight Isododecane little unable to evaporate Helps to blend well.
3. Isoeicosane have more weight A small amount of Isohexadecane It is not volatile. Helps to blend well
Use: As a solvent (solvent) or as a conductor (carrier) or disperser (disperser / spreader).
Mixing method: Mix together according to the desired recipe.
Usage rate: 1-25%
Product characteristics: clear liquid
Solubility: Can dissolve in silicones, hydrocarbons, isoparrafins.

“Ingredient-family evidence: volatile emollients such as isododecane are used to deliver lightweight, non-greasy sensory performance through structure-dependent physicochemical properties.”
“Closest hydrocarbon-emollient evidence: mineral oil improves skin softness, barrier function, and reduces transepidermal water loss; this supports the general emollient/occlusive benefit category, not isododecane specifically.”
“Closest moisturizer-component evidence: hydrocarbon occlusives are recognized moisturizer components that help reduce water loss and support barrier protection; applies to hydrocarbon family rather than direct isododecane efficacy.”
“Emollient sensory evidence: cosmetic emollients can be differentiated by spreadability, residue, stickiness, softness, and oiliness; supports claims about light skin feel for volatile emollient systems, not direct clinical skin benefit of isododecane.”
