Abstract

The invention provides a mild cosmetic composite, which contains 0.5-60% of polyethylene glycol (or polyoxyethylene)\polypropylene glycol (polypropylene) dimethyl siloxane and 0-99.5% of natural or synthetic lipid, and is suitable for removing make-up, washing or cleaning for sensitive skin.

Description

A kind of cosmetic composition of gentleness

[technical field]

The invention provides a kind of cosmetic composition of gentleness, contain Polyethylene Glycol (or polyoxyethylene) polypropylene glycol (or polypropylene) dimethyl siloxane 0.5-60%, natural or synthetic oils and fats 0-99.5% is fit to sensitive skin makeup removing, washing or clean skin and uses.

[background technology]

Because environmental pollution increases the weight of day by day, people cause the situation of skin allergy more and more by all means, thereby the crowd of allergic skin is on the increase, and is also more and more higher to the requirement of cosmetics, and wherein one of most important requirement is the cosmetics that are fit to own skin, milder.

Result according to Institute for Environment Hygiene and Health Related Product Safety, China CDC's investigation in 2003, in the cosmetics safety problem, 82.6% cosmetics contact dermatitis, inevitable requirement cosmetics are explored use in the process of recipe design safer, the raw material of milder.

Be the generation background that example illustrates this technology with makeup removing liquid below.

In the makeup removing liquid of mentioning on sale or the publication, the used surfactant of raw material has following several in the market:

1) alkyl polyoxyethylene ether class

2) imidazolines ionic surface active agent

3) alkyl polyglycereol esters

4) alkyl glucose glycoside surfactant

More than the acute skin irritation value of a few class raw materials all higher.Most sensitive skin have irritant reaction in various degree.

The invention provides a kind of oiliness cleansing composition; material choice polyoxyethylene/polyoxypropylene dimethicone in the prescription is as emulsifying agent; gentle natural liquid oils is as emollient and color make-up solvent components; when better removing color make-up; the protection skin of milder, have action temperature and, flushing is easily; noresidue, the makeup removing good effectiveness.

Compare with above surfactant, the acute skin irritation value of polyoxyethylene/polyoxypropylene dimethyl-silicon oils surfactant almost nil (acute skin irritation value 0-0.5 is non-stimulated), the main emulsifying agent that is used for the cream frost emulsion of high-grade skin care item on a small quantity, report is not before seen and is useful on the makeup removing series products, initiative of the present invention be applied to the series products of removing ornaments and formal dress, through part sensitivity crowd on probation simultaneously with on the market like product relatively, all can accept fully.

[summary of the invention]

The present invention adopts polyoxyethylene/polyoxypropylene dimethyl-silicon oils surfactant with natural vegetable oil, siloxanes, and liquid polarity wet goods is composite, for sensitive skin provides the washing series products of almost non-stimulated gentleness, can be used for makeup removing, all kinds of cosmetics such as clean.

Product of the present invention is characterised in that and contains following composition, contains following A) composition and B) item one or more compositions a kind of wherein:
