Embodiment 1

[0047] Colorless transparent stick (1)

[0048] The product is prepared by mixing all ingredients at about 115°C. After the wax had melted the homogeneous product was cooled to 70°C and poured into molds.

[0049] lanosterol 3

[0050] Squalane® to 100

[0051] Tridecyl 1,2,4-Benzenetriate 15

[0052] Hydrogenated Styrene / Methyl Styrene / Indene Copolymer 15

Embodiment 2

[0054] Colorless transparent rod (2)

[0055] Composition is manufactured by embodiment 1 method.

[0056] Lanosterol 8

[0057] Hydrogenated Polyisobutylene Add to 100

[0058] Tridecyl 1,2,4-Benzenetriate 25

[0059] Hydrogenated styrene / methylstyrene / indene copolymer 22

Embodiment 3

[0061] colored transparent stick

[0062] Lanosterol 6

[0063] Hydrogenated Polyisobutylene Add to 100

[0064] 1,2,4-tridecylbenzenetriate 24.97

[0065] Hydrogenated styrene / methylstyrene / indene copolymer 8

[0066] Red Ca++ lake (CI 15850:1) 0.02

[0067] Red 33 aluminum lake (CI 17200) 0.01

[0068] The lanosterol, copolymer, tridecyl trimellitate and hydrogenated polyisobutene are melted at a maximum of about 115°C while stirring at about 300 revolutions per minute. After complete melting, lower the temperature to 95°C, and add the pigment mixed with trimellitate in advance. The silicon dioxide is then added with stirring at about 350 rpm. After adding the silica, stir slowly while cooling down to remove air from the homogeneous mixture. The mixture was then poured into molds at 65°C.

Abstract

The invention relates to solid cosmetic compositions based on solidified oils, which, in conjunction with various additives, are particularly suitable for cosmetic sticks due to their waxy character and transparency. Said compositions are characterized in that they comprise 40 to 95 wt % of a cosmetically acceptable oil or oil mixture, 1 to 10 wt % lanosterol and 0 to 58 wt % of one or more cosmetic active substances or additives, all of which are related to the entire mass of the compositions.

Description

technical field [0001] The present invention relates to a solid cosmetic composition based on solidified oil. Due to their wax-like character and transparency, such compositions are particularly suitable for cosmetic sticks with various additives. Background technique [0002] The base of traditional transparent solid cosmetic formulations is usually fatty acid soaps, such as sodium stearate, sodium cocoate or those with other long-chain fatty acid radicals such as stearyl, isostearyl, palmityl or fat-based media . Basic ions such as sodium ions, lithium ions, and triethanolamine ions are usually used as counter ions. The resulting solid transparent formulations are especially suitable for use in soap particles, fragrances or antiperspirants, for example stearic monoethanolamide is known as a commercial product. [0003] In addition, mixtures of polyols with dibenzylidene sugars or dibenzylidene monosorbitol generally exceeding 50% by weight of polyol are known for their ...
