- Features
- SMA'RT Guard HEX is a high purity 1,2-Hexanediol that can be used in personal care formulations not only as a humectant, but also as a safe substitute of traditional preservatives. It has a broad anti-microbial ability with limited endocrine disrupting effect. Manufacturing of SMA'RT Guard HEX involves processes of reducing the undesirable odor of 1,2-Hexanediol and bringing the purity up to min 99.0%.
- It acts as a humectant, preservative and moisturizing giver. In addition, it can be used either alone or in combination with other preservatives to combat microorganisms directly and thus reduce or eliminate body odor, acne or mycoses. It is applicable in skin care products, deodorants and moisturizing formula-tions
