Polyquaternium-105

Polyquaternium-105, is a cationic homopolymer, with an average molecular weight of about 300,000, which is preferably used after oxidative or surfactant hair treatment. Based on the weight of a ready-to-use hair treatment agent, the proportion of polyquaternium-105 is generally 0.0001 to 10.0% by weight.

Environmental influences and oxidative hair treatments often result in poorer combability of dry and wet hair. Furthermore, the shine and moisture balance are negatively influenced by the attacked outer structure of the keratinic fibres. Conventional hair care products therefore contain conditioning polymers like cationic polymers or silicone oils. Conditioning polymers, however, lead to a layer formation on the hair shaft and thus often to a weighting of the hair. This causes problems in hairstyling, especially for people with fine hair (low volume, little hold and fullness of the hairstyle).

Acrylamidopropyltrimethylammonium chloride has a high cationic charge density and therefore binds effectively and completely to the negative charges of human hair.

It has been shown that the combination of cationic acrylamidopropyltrimethylammonium chloride with a fatty alcohol leads to an intensive conditioning of human hair. Hair conditioned with this product shows excellent wet combability and increased volume in dry condition.

Suitable fatty alcohols are saturated, mono- or polyunsaturated, branched or unbranched fatty alcohols with C6 - C30-, preferably C10 - C22- carbon atoms. Preferably used in hair treatment products are: decanol, octanol, octenol, dodecenol, decenol, octadienol, dodecadienol, decadienol, oleyl alcohol, eruca alcohol, ricinol alcohol, stearyl alcohol, isostearyl alcohol, cetyl alcohol, lauryl alcohol, myristyl alcohol, arachidyl alcohol, caprylic alcohol, caprine alcohol, linoleyl alcohol, linolenyl alcohol and behenyl alcohol, and their Guerbet alcohols However, the fatty alcohols are preferably derived from natural fatty acids, whereby it can usually be assumed that they are obtained from the esters of the fatty acids by reduction.

Alternatively, mixtures of different fatty alcohols can also be used. These are known as Stenol®, e.g. Stenol® 1618 or Lanette®, e.g. Lanette® O or Lorol®, e.g. Lorol® C8/C14/C18, HD-Ocenol®, Crodacol®, e.g.e.g. Crodacol® CS, Novol®, Eutanol® G, Guerbitol® 16, Guerbitol® 18, Guerbitol® 20, Isofol® 12/16/24/36, Isocarb® 12/16/24 commercially available

Also wool wax alcohols can be used (trade names: Corona®, White Swan®, Coronet® or Fluilan®).
