sensiva® SC 50 is a globally approved, versatile and multifunctional additive, as well as a very effective deodorant active. As an emollient and mild humectant, it improves the skin feel of cosmetic formulations. sensiva® SC 50 reliably inhibits the growth and multiplication of odour-causing bacteria, while at the same time not affecting the beneficial skin flora. Additionally, it can boost the efficacy of traditional preservatives and act as antimicrobial stabiliser in combination with other cosmetic ingredients.
Skin care properties
Medium spreading emollient
The selection of emollients is critical to the character of a cosmetic product. High contents of fast spreading emollients lead to light creams with a smooth skin feel. High contents of slow spreading emollients are used in rich creams with refatting properties. Medium spreading emollients close the gap between fast and slow spreading emollients, improving the refatting properties and extending the smooth skin feel of cosmetic formulations. To achieve a long lasting soft and smooth skin feel, a combination of fast, medium and slow spreading emollients is necessary.
sensiva® SC 50 is a medium spreading emollient with a spreading coefficient of about 700 mm2/10 min 1). The spreading properties are similar to those of dodecyl oleate, hexyldecanol or cetearyl isononanoate.
Moisturising properties play an important role in determining the overall aesthetics of an emulsion. The most frequently used moisturiser in cosmetic formulations is glycerin. However, higher use concentrations of glycerin may lead to some disadvantages in the skin feel of cosmetic formulations, such as slow penetration, tackiness or soaping (whitening during application). A sensory assessment test 2) has been performed on a glycerin-containing oil-in-water emulsion to determine if sensiva® SC 50 can compensate some well-known disadvantages of these formulas.
