Abstract

Cosmetic antiperspirants for nonaerosol use, having a content of methanesulfonic acid and/or at least one physiologically acceptable salt of methanesulfonic acid, which exhibit less textile staining than known antiperspirants.

First claim

What is claimed is:

1. A perspiration-inhibiting cosmetic agent for nonaerosol utilization, comprising in a cosmetically acceptable carrier
a) at least one perspiration-inhibiting aluminum salt in a total quantity from 2 to 40 wt %, preferably 8 to 35 wt %, particularly preferably 10 to 28 wt %, and extraordinarily preferably 12 to 20 wt %, where the “wt %” indications refer to the total weight of active substance (USP), free of water of crystallization and free of ligands, in the agent,
 and in addition thereto
b) 0.05 to 5 wt %, based on the total weight of the agent, of a methanesulfonic acid of the following formula (MS-1)

 or at least one physiologically acceptable salt of methanesulfonic acid selected from the group consisting of sodium, potassium, magnesium, calcium, manganese, zinc, and aluminum salts of methanesulfonic acid of formula (MS-1).

2. The agent according to claim 1 , wherein at least one cosmetic oil that is not a fragrance and not an essential oil is included.

3. The agent according to claim 1 , wherein zero to a maximum of 10 wt % free water is included, based on the total weight of the agent.

4. The agent according to claim 1 , wherein free water is included in a total quantity from 15 to 96 wt % based on the total weight of the agent.

5. The agent according to claim 1 , wherein at least one emulsifier agent and/or at least one surfactant is included.

6. The agent according to claim 1 , wherein the agent is an oil-in-water emulsion.

7. The agent according to claim 1 , wherein the agent is a water-in-oil emulsion.

8. The product according to claim 1 , wherein the agent is an aqueous solution and furthermore includes ethanol.

9. The product according to claim 1 , wherein the agent is a suspension of undissolved antiperspirant active substance in an oil.

10. The cosmetic agent according to claim 1 , wherein the agent is formulated as a stick, soft solid, cream, roll-on, dibenzylidene alditol-based gel, loose powder, or compacted powder, or has been applied onto a disposable substrate being a cloth, pad, or wad.

11. The cosmetic agent according to claim 1 , wherein no zirconium-including compounds are included.

12. A method for preventing and/or reducing textile discolorations and/or textile spots, where the method comprises the following method steps:
a) producing a perspiration-inhibiting cosmetic agent by mixing at least one perspiration-inhibiting aluminum salt, which is preferably zirconium-free, in a total quantity from 2 to 40 wt %, preferably 8 to 35 wt %, particularly preferably 10 to 28 wt %, and extraordinarily preferably 12 to 20 wt %, where the “wt %” indications refer to the total weight of active substance (USP), free of water of crystallization and free of ligands, in the agent, with a cosmetically acceptable carrier and with at least one methanesulfonic acid of the following formula (MS-1),

 or at least one physiologically acceptable salt of methanesulfonic acid,
b) applying the perspiration-inhibiting cosmetic agent onto the skin, in particular onto the skin of the armpits,
c) wearing a textile garment over the treated skin, and
d) washing the textile garment, in particular repeatedly washing the textile garment, where no, or reduced, textile discolorations and/or textile spots occur after washing, in particular after repeated washing.
