Humectant
Humectants are one of the primary building blocks of hair and skin care cosmetic formulations. Humectants are materials that are hygroscopic and are capable of retaining moisture over a wide relative humidity range.
In cosmetics they play an important role in hydrating the skin and hair, making them feel softer, enhancing suppleness, flexibility, and stretchability. They help to alleviate the drying conditions which threaten the appearance and well-being of the skin and hair caused by the environment.
Simply put, humectants have the ability to bind water to their molecules and want to do this to achieve a stable free energy state. Consequently, they are always very soluble in water.
Historically, Bayberry (Myrica Cerifera) has been used in folk medicine for its tonic, stimulant, and astringent properties, but the most popular use of this herb is for making candles.
Myristyl 3-Glyceryl Ascorbate is a stable vitamin C derivative. It is a modified 3-Glyceryl Ascorbate with an attached alkyl (myristyl or tetradecyl; C14) group. This modification adds lipophilicity and enables the molecule's emulsifying ability.
Palmitoyl sh-Tripeptide-1 Amide is a low molecular weight synthetic recombinant lipo-peptide derived from FGF-1 (Fibroblast Growth Factor-1; sequence part 99-101) that is involved in various cellular processes, including angiogenesis, keratinocyte organization, and wound healing.
Palmitoyl sh-Tripeptide-3 Amide is a low molecular weight lipo-peptide derived from Pro-Epidermal Growth Factor (EGF; sequence position 894-896) that stimulates cell growth, proliferation, and differentiation by binding to its receptor EGFR.
Palmitoyl-KTSKS (Palmitoyl Pentapeptide-4) is a synthetic lipo-peptide developed by Sederma with selective antimicrobial (not bacteriocide) activity and known under the trade name BB-Biont™.
PEG-150 is a long-chain homopolymer of ethylene oxide with an average molecular weight of 8000. It is supplied as small, white beads with a faint odor or odorless.
PEG-6 is a polyethylene glycol (with six ethylene glycol units) that is a clear, colorless liquid, almost tasteless, and odorless pharmacological-grade ingredient.
PEG-8 is a polyethylene glycol with polymerization level 8 which means that it contains 8 -CH2CH2O-
PEG-8 Stearate is a nonionic emulsifier in solid form, created through the esterification of vegetable oil-derived stearic acid with polyethylene glycols with an average molecular weight of 400. Its pH of 3% aqueous solution is 6, HLB Value of 11.5.
PEG-9 is a polyethylene glycol (with nine ethylene glycol units) that is a clear, colorless liquid that is almost tasteless and odorless. It has good solvent power for numerous substances sparingly soluble in water and is mainly used as a solvent to produce liquid preparations.
Phytantriol compound with three hydroxyl groups on one side and a long saturated hydrocarbon chain on the other side of the molecule. It is a slightly yellowish transparent viscous liquid with a characteristic faintly sweetish odor at room temperature.
Polyglycerin-3 is a water-soluble polymer with 3 glycerol units. It has a high refractive index making this ingredient extremely useful in the aqueous phase of transparent emulsion applications.
Polyglyceryl-3 Laurate is a monoester for laruic acid with a polyglycerol with three glycerin units. It is a clear to slightly hazy viscous liquid with a slight characteristic odor.
Polyquaternium-71 is a synthetic, highly ionized, hygroscopic, water-soluble polymer that effectively binds water molecules and delivers an intensive hydration effect for both skin and hair applications.
Potassium Azeloyl Diglycinate is a multifunctional ingredient that combines the effectiveness of azelaic acid with the moisturizing power of glycin. It is also known as Azeloglycine.
Potassium Olivoyl PCA is a vegetal softening lipo-amino acid as a fatty acid vehicle an emollient, and moisturizing agent, and a softening surfactant.
PPG-10 Methyl Glucose Ether is a propoxylated methyl glucose ether, a pale, yellow syrup (moderate-viscosity liquid) with a mild odor. It is an effective emollient, fragrance fixative, and humectant for hair and skin care products.
PPG-20 Methyl Glucose Ether is a propoxylated methyl glucose ether, a moderate-viscosity pale, yellow syrup (liquid) with a mild odor. It is an effective emollient, fragrance fixative, and humectant for hair and skin care products.
PPG-26/Dimer Dilinoleate Copolymer (trade name Pelemol® D-2000) is a clear viscous, pourable liquid that is extremely substantive and glossy. Substantivity to the skin is so intense that repeated washing with soap and water does not completely remove the product.
Propylene Glycol is diol alcohol (it contains two hydroxy groups in 1 and 2 positions—propane-1,2-diol), a humectant or humidifying and delivery ingredient used in cosmetics. It is a water-white, viscous, odorless, hygroscopic liquid with low volatility and is readily soluble in water.
Glycation occurs from the reaction of glucose and a protein that produces AGEs (Advanced Glycation Products), forming stable brownish-yellow compounds in the skin, hair, and the body as a whole.
Renovage™ made to extend the skin's youth span and works on the origin of youth and targets the cell actors which guarantee lifespan and youth. The age that we attribute to a face is a global assessment unconsciously based on several visual signs that are additive.
