Purpose: Two studies were conducted with a new topical panthenol-containing emollient (NTP-CE) to investigate the skin-moisturizing effect in healthy adults and tolerability in healthy infants. Methods: In Study 1 (N ¼ 44), a single skin application of NTP-CE was performed followed by a 4-week twice-daily application. Skin hydration and stratum corneum (SC) water content change (using Raman spectroscopy) were measured. In the 4-week Study 2 (N ¼ 65, aged 3-25 months), NTP-CE tolerability was assessed using a 5-point scoring system; skin hydration was determined in a subset (N ¼ 21). Results: In Study 1, mean AUC 0 À 24 h for skin capacitance change from baseline was 302.03 i.u. with NTP-CE and À15.90 i.u. in control areas (p < .001). With NTP-CE (at 4 h), the water content within the upper SC part was reduced (À45.10 vs. À13.39 g/cm 2 , p ¼ .013) and the water gradient increased (0.51 vs. 0.11 g/ cm 4 , p ¼ .036), indicating relocation of water into deeper layers. In Study 2, there was no statistically significant change from baseline in mean cutaneous tolerability scores. At days 7, 14, and 28, skin hydration had increased by 42%, 54%, and 49%, respectively (all p < .001). Conclusions: Single and prolonged NTP-CE usage is associated with sustained and deep skin moisturization. NTP-CE is well tolerated by healthy infants. ARTICLE HISTORY

“…ceramide 3), vitamin B 3 which is known to increase skin lipid production (9), and the prebiotic a-glucan oligosaccharide as key elements. In addition, NTP-CE incorporates a lipid lamellar technology which is characterized by a structure similar to the naturally occurring intercellular lipids in the epidermis.…”

(2017) A new topical panthenol-containing emollient: Results from two randomized controlled studies assessing its skin moisturization and barrier restoration potential, and the effect on skin microflora, Journal of Dermatological Treatment, 28:2, 173-180, DOI: 10.1080/09546634.2016 Purpose: Two randomized, intra-individual comparison studies were performed in healthy subjects to evaluate the skin moisturization and barrier restoration potential of a new topical panthenol-containing emollient (NTP-CE) (Study 1), and its effect on skin microflora (Study 2). Methods: In Study 1 (N ¼ 23), two skin areas, one challenged with 0.5% sodium dodecyl sulfate (SDS) solution and one unchallenged, were treated with NTP-CE for 3 weeks. Transepidermal water loss (TEWL), skin hydration, and intercellular lipid lamellae (ICLL) organization were measured at regular intervals during the study. In Study 2 (N ¼ 20), quantitative bacterial cultures were obtained over 6 h from a skin area undergoing wash stress with 10% SDS with subsequent single application of NTP-CE. Results: In Study 1, mean AUC for TEWL reduction from baseline was more pronounced with NTP-CE compared with control (À168.36 vs. À123.38 g/m 2 /h, p ¼ 0.023). NTP-CE use was also associated with statistically significant improvements in stratum corneum hydration and an increase in mean ICLL length from baseline (day 22: 120.61 vs. 35.85 nm/1000 nm 2 , p < 0.001). In Study 2, NTP-CE use had no negative impact on bacterial viability. Conclusions: NTP-CE use has favorable and lasting effects on barrier function and repair as well as skin hydration without negatively influencing bacterial viability. ARTICLE HISTORY

“…It is known from literature that topical application of fibronectin, a peptide component of the extract [39,40] and NADPH [41,42] is beneficial for wound healing. Recently presence of other peptides in the extract that are potentially active for wound healing has also been confirmed (D. De, unpublished results).…”
