Description

Hydroxycitronellal dimethyl acetal has a light, green, flowery odor similar to hydroxycitronellal. Colorless liquid; light floral odor.Soluble in most fixed oils, mineral oil, and propylene glycol; insoluble in glycerol. Combustible. Hydroxydihydrocitronellal Dimethyl Acetal is a colorless liquid with a weak, floral odor. Since the acetal is stable to alkali, it is used occasionally in soap perfumes.Hydroxycitronellal dimethyl acetal has a light, green, flowery odor similar to hydroxycitro

colourless, slightly oily liquid with delicate green floral taste and floral odour

8,8-Dimethoxy-2,6-dimethyl-2-octanol is a tertiary alcohol.
