Cream to Oil technology for Suncare and Daily Care

The following formulation examples are showing an innovative texture thanks to Cream-to-Oil

technology: a fluid sun care lotion with UV protection that combines a high level of UVB screening

with photostable, excellent UVA protection. Light and refreshing on application, it transforms into

oil when rubbed in leaving the skin smooth and protected. The caring massage effect is a feel-

good sensation.

This technology combines the use of the suitable consistency agents and polymers (impact on

sensory, viscosity and stability), emollients (impact on sensory, spreading surface and massage

time; transformation from cream to oil can be felt from 25% by weight of emollient and appears

faster when emollient >40 % by weight and more intense in presence of volatile emollients) and

emulsifiers (transformation from cream to oil faster when lower quantity).

The described cosmetic or pharmaceutical compositions/preparations may contain one or more

compounds as described below.

Emulsifiers

As emulsifier systems, we intend any structural elements used primary to stabilize the cosmetic or

pharmaceutical preparation by reducing the interfacial tension between the oil and the water.

Such category of ingredients could provide additional characteristic such as easy spreadability on

skin, water resistance of the formulation, film-forming effect on skin, dispersing effect on solid

particles. All those properties contribute to improve/optimize the overall SPF values of the

cosmetic or pharmaceutical preparations.

Emulsifier systems are classified according to their ionic characteristics and their hydrophilic-lipophilic

balance (HLB). They may comprise for example; carboxylic acids and their salts, alkyl

phosphates or phosphoric acid esters, ethoxylated carboxylic acids or polyethyleneglycol esters,

linear fatty alcohols, fatty alcohol polyglycolethers, fatty acid polyglycolethers, fatty acid polyglycol

esters, fatty acid and polyglycerol esters, monoglycerides and polyol esters, sorbitol or sorbitan

and their derivatives, glucose derivatives, sulfates and sulfonates derivatives, silicone emulsifiers.

Particularly suitable emulsifiers for Cream-to-Oil technology are:

 Eumulgin® BA: Beheneth-25

 Eumulgin® BA: Beheneth-12

 Eumulgin® B2: Ceteareth-20.

Emollients

As emollients, we intend any oil phase ingredients that provide emolliency on skin. Such ingredients

could act as solvents for UV absorbers and as dispersants for sunscreens/pigments. Usually, they

exert a positive influence on the overall skin sensory properties of cosmetic or pharmaceutical

preparation. The spreading ability is an important and objective criterion to distribute uniformly and

homogeneously the UV filters on skin for an optimized UV protection.

Solvent property is expressed, for example, via its ability to keep dissolved cr...
