Lehtonen 1,* Indeed, HA with low molecular weight (20-300 kDa) passes through the stratum corneum in contrast of the impermeability of high molecular weight HA (1000-1400 kDa). Conclusion: Raman spectroscopy represents an analytical, non-destructive, and dynamic method to evaluate the permeation of actives in the skin layers.

2019 Acetyl-Galactoglucomannan. 26.

Galactoglucomannan constitutes the major component of softwood hemicellulosic fraction (coniferous trees) and forms approximately 15–25% of wood dry weight [12]. Galactoglucomannans are significant structural components of both primary and secondary cell walls in higher plants.

Light, scattering and intrinsic viscosity measurements were made in water and in alkaline borate. The molecular weight and viscosity in water were 63,800 and 0.48 dl./g., and in borate solvent, 27,600 and 0.27 dl./g., respectively, indicating that aggregation is present in water. In this study, hydrogels based on acetylated galactoglucomannan (AcGGM)—a hemicellulose present in softwood—were synthesized and examined for their properties in drug‐release systems using two model substances of different molecular weight, size, and polarity (caffeine and vitasyn blue). The primary hemicellulose in softwoods is O-acetyl-galactoglucomannan (GGM), representing approximately 20% of the dry weight. GGM consists of a backbone of β-(1 → 4)- d -mannopyranosyl and β-(1 → 4)- d -glucopyranosyl units decorated with single α-(1 → 6)-linked d -galactopyranosyl units attached solely to the mannopyranosyl units.
