Applications

The best new technology can fail if the tactile properties of a cosmetic product are not acceptable.

Sensory attributes, such as spreading, tackiness, greasiness or absorption, play an important role in formulating cosmetics. Only a combination of optimal sensory properties combined with functionality will result in an excellent product. Emollient properties and rheology are obviously important formulation parameters for skin application. As these cannot be measured by any test method, expert panels are necessary to evaluate them in sensory assessment tests.

Some actives used in cosmetic formulations can negatively influence sensory attributes. Glycerine used in high amounts is known to impair the tactile properties of cosmetic formulations while on the other hand having very good moisturising properties.

Emollients in a balanced combination can help to improve the tactile properties of cosmetic emulsions. Beside their emollient character, some ingredients meet many other demands in cosmetic formulations. Some multifunctional cosmetic additives can be used as moisturiser or solubiliser. Several of them show certain antimicrobial efficacy or can improve the efficacy of traditional preservative actives.

Ethylhexylglycerin is a representative of the 1-alkyl glycerine ethers. It is a high purity, colorless and almost odorless liquid with excellent properties for use in cosmetic formulations.

In the year 1992, ethylhexylglycerin (sensiva^® SC 50) was introduced to the cosmetic market as a commercial product. It is a skin care additive and deodorant active. As a new substance, it is listed on the ELINCS files.
