Hostapon® CLG Mild Surfactant
Knowde Enhanced TDS
Identification & Functionality+
Features & Benefits+
Hostapon® CLG is a very mild co-surfactant for the cosmetic industry, based onL-glutamic acid, a naturally occuring amino acid. It is used mainly for theproduction of hair and body care products, such as shampoos, shower gels,liquid soaps, cleansing lotions and baby care products, that are gentle to the skin. Hostapon® CLG is free of preservatives.
Hostapon®CLG is particularly suitable for the production of shampoos fordamaged and dry hair because of its conditioning action. Additionally Hostapon®CLG shows synergy with cationic polymers and help to reduce the amount of thelatter products.
Hostapon®CLG is also suitable for the production of shower gels with specialcare effects (shower creams, 2 in 1 shower gels) and mild cleansing lotions for sensitive skin. Hostapon® CLG is responsible for an improved, gentle skin feeling.
Mild baby shampoo formulations can be formulated with Hostapon® CLG inconjunction with Genagen® LAA (Sodium Lauroamphoacetate) and Genagen® CAB (Cocamidopropyl Betaine).Generally, Acylglutamates like Hostapon®CLG improve the dermatologicalcharacteristics of surfactant formulations containing Sodium Laureth Sulfate.
Shampoos which combine Acylglutamates with Sodium Laureth Sulfate as a base surfactant have reduced tendency for deposition of Sodium Laureth Sulfate residues on the skin and thus reduce irritancy.
Surfactant formulations containing Hostapon®CLG also show improved compatibility with cationic surfactants.
Hostapon®CLG may also be used as hydrophilic co-emulsifier in O/W-emulsions especially in combination with the emulsifiers Emulsogen® SRO or Hostacerin® DGI.

Technical Details & Test Data+
Hostapon® CLG shows marked surface and interfacial activity. Above that critical micelle concentration (CMC about 0.17 g/l), surface tension is reduced to values below 30 mN/m.
Resistance to water hardness
Hostapon®CLG shows moderate resistance to hard water. Turbidity occurs at water hardness values from 10° German hardness.
Hostapon® CLG has very good foaming behaviour, particularly in the acid range.Maximum foaming is obtained in the region of pH 5.In determining the foaming power of Hostapon® CLG by the ROSS-MILES method, very good foaming values are obtained in the pH range 4-7.In formulations, Hostapon® CLG improves the overall foam structure.
Washing and degreasing action
Hostapon® CLG has a mild, gentle cleansing action. Because of it’s affinity for keratin (substantivity), it leaves an extremely pleasant silky feel on the skin and improves hair care properties (wet and dry combing, handle) when used in shampoos.
Viscosity in mixtures with other surfactants
As a co-surfactant in surfactant formulations, Hostapon® CLG shows a slight viscosity-reducing effect. But in mixtures with Genapol® LRO (Sodium Laureth Sulfate) and with the addition of commonly used consistency modifiers such as Genapol®LA 030 (Laureth-3), practical viscosities with acceptable sodiumchloride contents are easily obtained. The viscosity of comparable formulations is lower with Hostapon®CLG compared to Hostapon®CCG (Sodium Cocoyl Glutamate).
At room temperature (20-25 °C), Hostapon® CLG is a clear to slightly hazy liquid. At temperatures below + 5 °C, this turbidity can increase and in some cases is accompanied by the formation of sediment.In case of sediment formation the product should be homogenized at 40-50°Cwhile stirring.
