It is well known that hair that has been sensitized (i.e., damaged and / or embrittled to varying degrees by atmospheric agents or mechanical or chemical treatments or treatments such as dyeing, bleaching and / or permanent waving operations) is often difficult · difficult · difficult · difficult · difficult · difficult · difficult · difficult · · · · · · · · · · · · · · · · · · · · · · · • Unravel and comb according to the latest fashion and lack softness or softness.

It has already been recommended to use conditioners, in particular insoluble conditioners, in mixtures or in the care of keratinous substances, as hair, to facilitate the unraveling of the hair and to make it soft, shiny and supple or elastic.

If the insoluble nature of certain conditioners, such as silicones or oils, is given, it is sought to maintain the uniformly dispersed λ 'of the medium without reducing viscosity or washing or foaming properties. given mixtures. Silicones should also be supplied to treated keratin so that after application they are given properties such as softness or softness, shine and ease of unraveling.

It is also known that products, in particular cosmetic products, which have an iridescent, iridescent, shimmering or shimmering or metallized appearance or effect are widely favored by consumers at the expense of their aesthetic appeal or attractiveness and the fact that they give the appearance of richness, pomp or abundance. The compositions which provide this effect are pearl beads, which usually contain crystals which remain dispersed in the compositions and which reflect light.

Tl rinning agent means a composition that produces an iridescent (iridescent or color changing), matt shimmering or shimmering or metallized appearance or effect.

Currently, there are few means for effectively keeping insoluble conditioners in suspension, as this is a difficult problem to solve; nevertheless, derivatives have already been proposed for the esters with long chain or pole carbohydrates such as xanthan gum. However, long chain ester derivatives may present crystallization problems which lead to a change in the viscosity of the compositions over time; gelling agents also have drawbacks or disadvantages, namely, on the one hand, it is difficult to develop the appropriate foam with detergent compositions containing xanthan resin (poor foam initiation) and, on the other hand, lack the smooth texture (structure) and flow in droplets or lumps, users positively appreciate.

Derivatives of ethers or three long chain ethers such as those described in patent applications EP 45 7,688 and WO 98/03 1555 are also known. However, these compositions opacify or cloudy the compositions without giving them any or less effervescent effect.

Attempts have already been made to improve the effect of adding thickeners and / or other chpear agents, but in this case too much the viscosity, or the mixture or composition is no longer stable.

The applicant has discovered. and that is, what constitutes an object of the invention is that the use of a linear, saturated fatty alcohol containing a minimum of 50% by weight of alcohol. The composition comprising 22 atomic compositions of atoms provides a beading effect with and / or improves the beading effect of compositions comprising at least one surfactant base and at least one opacifying agent and / or a beading agent.
