Reducing preservative content
SymTriol contains 1,2-octanediol and 1,2-hexanediol which are both moisturisers that also hold anti-microbial properties and can therefore help reduce the amount of preservative required in a formulation.
Added to the patent-pending blend is Methylbenzyl alcohol which is a nature-identical compound used in fragrances.
It is often added to cosmetics and perfumes for its floral scent, although formulators using SymTriol may, if desired, mask the scent with other fragrances.
Methylbenzyl alcohol also has antifungal effects. Symrise claims that its presence complements the anti-microbial properties of the 1,2-alkanediol blend.
SymTriol is therefore marketed to appeal to formulators looking to reduce use of preservatives such as parabens and formaldehyde donors.
Applications and technical details
Germany-based Symrise said the multifunctional ingredient is suitable for a wide range of cosmetic applications including gels, creams and lotions.
It is a clear, nearly colourless liquid that is soluble in cosmetic esters, glycols and ethanol, and it is compatible with most raw materials, added the flavour and fragrance firm.
SymTriol (INCI: Caprylyl Glycol, 1,2-Hexanediol, Methylbenzyl Alcohol) is stable at a pH-value of 3-8 and has excellent temperature stability.
The recommended dosage of SymTriol is 0.5-1.0 per cent.
