Composition

Abstract

Hair treatment composition comprising from 40 to 95% wt. of the composition silicone elastomer, 0.01 to 5% silica and from 0 to 2% wt. water.

Claims

1. A composition comprising from 40 to 95% wt. of the composition silicone elastomer 0.01 to 5% silica, and from 0 to 2% wt, water, wherein: the silica is pre-suspended in mineral oil or fragrance oil, and the composition is in the form of a hair treatment composition, and the silicone elastomer comprises dimethicone, vinyl dimethicone, hydrogendimethicone, and 2,4,6,8-tetravinyl cyclotetrasiloxane.

2. The composition according to claim 1 wherein the silica is fumed silica.

3. The composition according to claim 1 wherein the oil is light mineral oil.

4. The composition according to claim 1 wherein the oil is fragrance oil.

5. The composition according to claim 1 further comprising from 1 to 30% wt. volatile silicone.

6. The composition according to claim 1 wherein the composition further comprises a silicone elastomer comprising isododecane and dimethicone/bis-isobutyl PPG-20 crosspolymer.

7. The composition according to claim 1 wherein the composition further comprises a silicone elastomer comprising isodecyl neopentanoate and dimethicone/bis-lsobutyl PPG-20 crosspolymer.

8. The composition according to claim 1 wherein the composition further comprises a silicone elastomer comprising isohexadecane and dimethicone/bis-isobutyl PPG 20 crosspolymer.

9. The composition according to claim 1 wherein the composition further comprises a silicone elastomer comprising cyclopentasiloxane and dimethicone crosspolymer.

10. A composition comprising from 40 to 95% wt of the composition silicone elastomer, 0.01 to 5% silica, from 0 to 2% wt. water, and an MQ resin that is a condensation product between monofunctional silane (M) and tetrafunctional silane (Q), wherein the silicone elastomer comprises dimethicone, vinyl dimethicone, hydrogendimethicone, and 2,4,6,8-tetravinyl cyclotetrasiloxane.

11. The composition according to claim 10 wherein the MQ resin is present in an amount of from 0.1 to 5 wt % of the composition.

(3) Process 1. Weigh the full amount of elastomer into the vessel. 2. Start to mix at a slow speed (50-100 rpm) and gradually add the MQ Resin CF-0410. 3. Once the mixture is thoroughly blended add the fragrance. 4. In a side vessel weigh out the full amount of Lytol mineral oil and start the stirrer at a very low speed (50 rpm) ensuring the blades are under the liquid level to avoid aeration. 5. Gradually add the aerogel powder to the lytol whilst continually mixing. Add over a minimum of 10 minutes to ensure a smooth mix is achieved. Check there are no lumps in the mixture. This will form a thick liquid. 6. Add the crodamol to the lytol and aerogel premix and stir slowly until the air bubbles are fully released. 7. Slowly add the aerogel side mix to the main vessel containing the elastomer. Mix thoroughly but slowly to avoid aerating the batch. 8. Continue to mix until you have a smooth consistency and a translucent light product.
