Embodiment 1
[0299] Example 1: Polyorganosiloxanes according to the invention which are not toxic in contact with the skin Preparation of Ax
[0300] Oil 1: α,ω-bis(trimethylsilyl)-poly[dimethyl,methyl[3-(2,2,6,6,-tetramethylpiperidin-4-yloxy) Propyl] siloxane, (provided by Bluestar Silicones France 21645 Oil) - Viscosity: 10000mPa.s.
[0301] Oil 2: α,ω-bis(trimethylsilyl)-poly[dimethyl,methyl[3-(2,2,6,6,-tetramethylpiperidin-4-yloxy) Propyl] siloxane, (provided by Bluestar Silicones France 21650 Oil) - Viscosity: 90000mPa.s.
[0302] For oils 1 and 2, before the treatment according to the invention, the proportion of oligomers with a molecular weight M<1000 Daltons was approximately 2 to 2.6% relative to the total molecular distribution.
[0303] "Enhanced devolatilization" according to the invention : The oil is added to the reactor, mechanically stirred and gradually heated to 170°C (using a heat transfer fluid, which transfers heat through the walls of the device). Intens...
Embodiment 2
[0309] Embodiment 2: the preparation of cosmetic composition (shampoo):
[0310] Shampoo compositions were prepared, some according to the invention (compositions I1, I2, I3, I4, I5 and I6) and others comparative (compositions C1 and C2).
[0311] Table III: Shampoo Compositions
[0312]
[0313] "AM" means active substance
[0314] Shampooing was carried out by applying compositions I1, I2, I3, I4, I5 and I6 and compositions C1 and C2 to pre-moistened sensitive hair. Lather up the shampoo, let it work for 10 minutes, then rinse thoroughly with water. The appearance of wet and dry hair was evaluated by a panel of skilled artisans.
[0315] result : On wet hair, the compositions I1, I2, I3, I4, I5 and I6 according to the invention act identically to the comparative compositions C1 and C2, the roots of the hair treated with the composition A according to the invention are more separate. On dry hair, both visual and tactile smoothness is improved for hair treated with...
Embodiment 3
[0316] Embodiment 3: the preparation of cosmetic composition (shampoo), this composition comprises 2.5g according to Polyorganosiloxane A oil actives with sterically hindered piperidinyl functional groups according to the invention
[0317] The same compositions as described in Example 2 were prepared, but using 2.5 g of oil actives with piperidinyl functionality (A1 to A6) instead of 1.5 g of the comparative test composition. Indeed, due to the harmlessness of oil A according to the invention (not classified as R43), it is now possible to formulate compositions (A1 to A6) with concentrations of oil with piperidinyl functionality greater than the 2 g threshold of active substance.
[0318] Table IV: Shampoo Compositions
[0319]
[0320] The same test as in Example 2 was carried out.
[0321] Results: On dry hair, the smoothness of the hair treated with the compositions I7 to I12 according to the invention was improved both visually and tactilely compared to the compar...
