Broad spectrum preservative
Symrise has added SymOcide®
PS to
its portfolio of preservatives. The broad-spectrum preservative system complies with the legal regulations of most
countries. Cosmetic manufacturers can use it for a multitude of cosmetic applications such as creams, lotions, shampoos and decorative cosmetics. SymOcide®
PS, a synergistic mixture of the
preservative phenoxyethanol and 1,2-alkanediol, is a patent-pending broad-spectrum preservative system suitable for versatile use. It helps to keep the amount of preservatives in formulations low, and avoid the use of parabens and formaldehyde donors. All ingredients have a good safety profile and many years history of use. SymOcide®
New modified corn starch
PS works in leave-on products, as well
as rinse-off products. As it is miscible with lipophilic ingredients, such as cosmetic esters, it can also be used as a preservative in waterless formulations such as decorative cosmetics. Other benefits the product offers: It is a clear liquid which is easy to handle and formulate, hence no heating is required during production. Excellent stability at both high and low pH values and temperatures makes it compatible with most cosmetic ingredients and suitable for many types of packaging.

AGRANA manufacture and distribute starch based raw materials which are particularly beneficial for applications in the cosmetic industry. It offers high quality natural bio polymers which have been developed and produced using environmentally friendly processes. At in-cosmetics 2012, AGRANA is presenting a new cosmetic product, AGENAFLO 9050, for the first time. This hydrophobically modified corn starch is suitable for use in skin care, decorative cosmetics and toiletries. AGENAFLO 9050 has a very high oil and moisture absorbency power and an excellent emulsifying effect, so it can improve emulsion stability which is beneficial for achieving long-lasting wear and increased coverage, in decorative cosmetic applications for example. It is a white, free flowing powder that provides a smooth velvety feeling when applied to the skin. This is due to its uniform granular shape and particle size distribution. Such attributes are preferred for their application in lotions and creams, powders, colour cosmetics and deodorants.

Glycol alternative offers excellent effects
Zemea® propanediol, a unique offering from DuPont Tate & Lyle
BioProducts, is a natural alternative to petroleum-based glycols and glycerin.
New testing of Zemea® was conducted to evaluate its antimicrobial
efficacy in aqueous-based formulations. This was an extension of testing completed last year, showing you could reduce your preservative level by 50% with the addition of 2%-6% of Zemea® in the formulation.
In this new testing an oil-in-water skin care emulsion was chosen as the base material. Five preservative systems were tested at 25% of their recommended use level with the addition of 6% Zemea® Zemea® worked well with the lower preservative levels and boosted
.
’s outstanding skin-friendly performance, including lack of skin irritation, enhanced moisturisation and excellent aesthetics makes it an excellent natural substitute for petroleum-based ingredients, such as propylene glycol and butylene glycol. Zemea®
