INCI Functions:
Skin conditioning agent - Emollient. Emollients have the characteristic of enhancing the skin barrier through a source of exogenous lipids that adhere to the skin, improving barrier properties by filling gaps in intercorneocyte clusters to improve hydration while protecting against inflammation. In practice, they have the ability to create a barrier that prevents transepidermal water loss. Emollients are described as degreasing or refreshing additives that improve the lipid content of the upper layers of the skin by preventing degreasing and drying of the skin. The problem with emollients is that many have a strong lipophilic character and are identified as occlusive ingredients; they are oily and fatty materials that remain on the skin surface and reduce transepidermal water loss. In cosmetics, emollients and moisturisers are often considered synonymous with humectants and occlusives.
Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.

Abstract. Hydrophobic bioactives can be more easily incorporated into food and have their bioavailability enhanced if nanostructured lipid carriers (NLC) are used as carriers. In the present study, beta-carotene-loaded NLC were produced by low emulsification using murumuru butter and a mixture of Span 80 and Cremophor RH40 as surfactants. Their average diameter was 35 nm and alpha-tocopherol was required to protect the encapsulated β-carotene. Besides the evaluation of their physicochemical stability, NLC were submitted to dynamic in vitro digestion and cell viability assays with Caco-2 and HEPG cells. The bioaccessibility of beta-carotene in the dynamic system was about 42%. Regarding cell viability, results indicated NLC were toxic to the cell cultures tested. Such high toxicity is probably related to the type of surfactant used and to the extremely reduced particle size, which may have led to an intense and fast permeation of the NLC through the cells.

Abstract. This manuscript aimed to evaluate the adsorption of ibuprofen (IBU) and naproxen (NPX) using chemically activated carbon (CAC) with ZnCl2 synthesized from the waste of murumuru (Astrocaryum murumuru Mart.). The adsorbent was characterized in terms of its textural and physicochemical properties by determining its specific surface area (SBET), pore volume (Vtotal), percentage of ash, moisture, and yield, by FT-IR spectroscopy, XRD and TGA/DTA, as well as surface functional group, surface pH, and zero-charge point (pHPZC) analyses. Batch adsorption testing was carried out to evaluate the effect of adsorbent dosage, contact time, and pH. Adsorption mechanisms and the nature of the process were elucidated through kinetics, equilibrium and thermodynamics studies. The best results of removal percentage (>70%) and adsorption capacity (>2.2 mg/g) for both adsorbates were obtained with 0.15 g CAC, pH 3.0 and 360 min. The kinetics followed the pseudo-second-order model, with external diffusion the rate-determining step. The isotherms were well fitted by the Freundlich isotherm. The thermodynamic data revealed the endothermic, physical, and spontaneous nature of the adsorption process. The results obtained in this work reveal that CAC can be used as an efficient and viable alternative adsorbent for the removal of ibuprofen and naproxen in effluent treatment processes.

Development of an environmentally friendly formulation of silk fibroin combined with fatty acid from Astrocaryum murumuru Mart. effective against Aedes aegypti larvae. Journal of Drug Delivery Science and Technology, 75, 103626.
Abstract. The Aedes aegypti mosquito is a vector of several diseases, including dengue, yellow fever and the Zika virus. Synthetic insecticides such as chlorpyrifos and chlorothalonil have been used to control this vector, despite causing damage to both the environment and humans. Research into natural active compounds with a low environmental impact is therefore required. The present study developed an environmentally friendly formulation of silk fibroin (SF) combined with fatty acid esters [ethyl (FAEE-SF), propyl (FAPE-SF) and butyl (FABE-SF)] from A. murumuru fat, which was effective against larvae of the Ae. aegypti vector. The FABE-SF nanoparticle induced a higher mortality rate in Ae. aegypti larvae after 48 h (LC50 = 21.35 μg/mL). The stability of the nano was monitored for 21 days, and FABE-SF exhibited greater stability throughout this period, with average particle, zeta and PDI values of around 217.5 ± 0.85 nm, −25.6 ± 3.24 mV and 0.338 ± 0.01, respectively. This is the first work of its type to identify the larvicidal activity of fatty acid esters from A. murumuru, combined with silk fibroin, against Ae. aegypti.

Production, chemical composition, and fatty acid profile of milk from buffaloes fed with cupuaçu (Theobroma grandiflorum) cake and murumuru (Astrocaryum murumuru) cake in the Eastern Amazon.

Abstract. The objective was to evaluate the effect of concentrate supplementation using by-products of the Amazonian industry on milk production, milk composition, and milk fatty acid profile of dairy buffaloes. Twelve lactating buffaloes (544.5 ± 35.6 kg, 6.4 ± 2.2 years old, 59 ± 6 days in milk) were allotted in a pasture of Mombaça grass and managed under rotational grazing (4 days occupancy/28 days rest). A 3 × 3 Latin square was adopted, and each animal alternately received three supplementary treatments based on corn bran + soybean meal or cupuaçu cake or murumuru cake for 21 days per treatment. Murumuru cake increased the levels of lauric acid and myristic acid in the milk (p < 0.05). Murumuru cake reduced the unsaturated fatty acid contents in the milk compared with animals fed control diet or cupuaçu cake (24.27% vs. 25.24% vs. 25.08%). The n-6/n-3 ratio was 2.6, 1.97, and 2.0 in the control, cupuaçu, and murumuru groups, respectively. Based on this parameter, cakes made from cupuaçu as well as murumuru could be considered to be adequate for inclusion in dairy water buffalo feed. However, the murumuru cake addition requires some caution because its use induces the secretion of higher levels of lauric and myristic fatty acids that are related to human cardiovascular disease.
