Aloe Vera is one of the most common and oldest medicinal plants. The robust plant flourishes in warm climatic regions on calcareous and sandy soils. Aloe Vera is cultivated in large plantations in Central America, USA, China and many other countries. Harvested from at least 3-year-old plants, a maximum of 4 outer leaves per crop are cut. The leaves are washed first. Subsequently peeled and the gel removed. The genuine gel is a viscous mucus of 5% heteropolysaccharides in water and is not storable. Therefore, only gently stabilized and concentrated forms are offered: 10 or 40 fold thickened gel as well as approximately 200 fold concentrated freeze-dried powders. The production of aloe vera gel depends on the combination of care, experience and “know-how”. Satcotek’s suppliers are experienced producers who are well practiced in the process.
Pure Aloe Vera gel has a pH of about pH 4.5 (TDS). The main ingredients of the cosmetically used “inner leaf gel” are: polysaccharides such as acemannan, glucomannan and mannose derivatives. In addition, there are small amounts of vitamins (B1, B2, tocopherol), amino acids (lysine, threonine, valine), enzymes (oxidase, amylase, lipase) and anthraquinones (e.g. aloin, barbaloin, emodin) and further secondary components (e.g. phytosterols, salicylic acid) . The anthraquinones (alonine) derived from the leaf and cell tissue are removed to levels below 10 ppm. A maximum of 50 ppm is recommended.
The combination of more than 200 active ingredients makes Aloe Vera unique:
Pure aloe gel reduces itching, is cooling, anti-inflammatory, antibacterial and moisturizing. The antioxidant effect of aloe vera gel is well known. The Aloe Vera gel stimulates collagen and elastin fiber production as well as cell division and improves the elasticity of the skin.
Animal studies showed evidence of antiphlogistic and wound healing effects.
Because of its rich active spectrum, the Aloe Vera Gel is used in an almost unmanageable range of cosmetics. In cleansing milk and body lotions. In lip care, makeup and facial masks; In hair conditioners and conditioners, in shower gels, as a component of sun cream and self-tanning agents; In depilatories and moisturizers.
For a sufficient effect in cosmetics Aloe Vera gel 1: 1 should be added about 10-20%. The weakly acidic pH-value must be taken into account during formulation.
The most active ingredient is Aloe Vera Gel 1: 1. As alternatives to fresh gel, sprayed or freeze-dried pure Aloe Vera powder 100: 1 and 200: 1 is available. These concentrates are sterile and preservative-free and can be easily formulated.
Aloe Vera Gel 200: 1 is used with 0.1-0.5%. The gel prepared there from can be easily incorporated into warm O / W emulsions.
0.1% aloe vera powder 200: 1 corresponds to about 20% aloe vera 1: 1 gel. With 0.5% Aloe Vera Powder 200: 1 or 1% Aloe Vera Powder 100: 1 in water you can get a liquid product which corresponds to the pure Aloe Vera Gel 1: 1.
