The cosmetic base is comprised of an anhydrous mixture of an effective amount of at least one first non-emulsifying, gellable silicone elastomer; an effective amount of at least one second non-emulsifying silicone elastomer wherein said second silicone elastomer is nonsustainable and nonpilling; at least one non-aqueous solvent; and an effective amount of at least one water insoluble structuring agent which is compatible with said solvent and which has a melting point of between about 45°C and about 95°C.; and at least one pigment.

Wasp and Hornet Spray Uses Natural Oils
• US Patent No. 8,394,358 B2; Sterling International Inc., Spokane, WA, has patented a wasp, hornet and yellow jacket spray repellant and nest pesticide. The insecticidal composition consists of lemongrass oil, clove oil, rosemary oil and geranium oil.

Tattoo Removal System Uses Laser

Organic Residue Remover
• US 8,394,751 B2;  W. M. Barr & Company, Memphis, TN, has patented an organic residue remover composition. It is obtained by mixing at least one water insoluble hydrophobic compound; at least one water soluble glycol ether, at least one water insoluble glycol ether; at least one aromatic alcohol; at least one surfactant; optionally at least one hydrotrope; and water.

Pearlescent Agent Slurry For Liquid Treatment
• US Patent No. 8,394,752 B2; The Procter & Gamble Company has patented an inorganic pearlescent agent slurry suitable for use in a liquid treatment composition. The slurry consists of inorganic pearlescent agent; organic solvent, selected from the group consisting of glycerol, sorbitol and mixtures thereof; a rheology modifier; and a surfactant.

LVMH Patents Rinsable Skin Care Mask
• US Patent No. 8,394,363 B2; LVMH Recherche, Saint Jean de Braye, France, has patented a cosmetic rinse-off mask composition for the skin. It contains at least one water-retaining superabsorbent polymer that is a crosslinked sodium or potassium polyacrylate in the form of particles in a substantially completely hydrated state; at least one agent that is a film-forming agent, a gelling agent or a thickening agent; and a substance having a moisturizing effect.

Method of Assessing 3D Fabric Feel Patented by P&G
• US Patent No. 8,394,753 B2; The Procter & Gamble Company has patented a method of identifying an active for use in fabric care. It is comprised of the following steps: assessing a friction test ratio of the active; assessing a compression test ratio of the active; and assessing a stiffness test ratio of the active.

Transparent Candles Made from Amino Acids
• Transparent candles have fallen in and out of favor with consumers for the past 15 years. The US market has been the initial testing ground for most of these products. However, consumers’ initial enthusiasm for the product did not seem to last as the product’s overall performance has always been measured against paraffin. Some of the underlying issues with transparent candles included safety and poor fragrance performance.

A recent and interesting transparent candle introduction has come from Firmenich Fragrance Company in a product that obtained its gelling properties from two amino acids supplied by Ajinomoto. These amino acids are frequently used in personal care products as viscosity modifiers in creams and shampoos and, more recently, in clear lipsticks and antiperspirants. This transparent candle base formulation in the form of gel utilized hydrocarbon oils with the following gelling agents: dibutyl lauroyl glutamide and dibutyl ethylhexanonyl glutamide. These two gelling agents are present in an amount of 1 to 10% by weight relative to the total weight of the gel candle base. It is further comprised of a perfume in an amount of 1 to 15% by weight, relative to the total weight of the candle base.     
In addition, the introduction of polyamide resins to Firmenich’s amino acid transparent candle has created a product that meets all of the safety criteria. Of particular interest to this development are: the polyether polyamides (PEPA), ester terminated polyamides (ETPA), ester terminated polyester-amides (ETPEA) and the tertiary amide terminated polyamides (ATPA), trade name Sylvagel A200 and Sylvagel A2614V; especially the Sylvagel A2614V. These compounds are capable of gelling  non-polar and low polarity liquid organics. They are of low molecular weight resins, thermoplastics with softening point in the range of 75-100°C, which are produced from vegetable based raw materials.
Firmenich’s transparent candle, which used amino acids as its main gellant, is described in Patent No. WO 2011/030265A1. It utilized one or more of the polyamides described above. The tertiary amide terminated  polyamide (ATPA), particularly the Sylvagel A2614V, builds structure to work in synergy with isostearyl alcohol and/or oleyl alcohol, but also to lower the melt point, to lower the transparent candle’s pool temperature.
