Description

Cleasing compositions

Technical field

The present invention relates to Cleasing compositions.The invention particularly relates to gentle personal cleaning compositions, said composition demonstrates for example deposition of the improvement of antimicrobial, sunscreen and vitamin of skin care actives.In addition, compositions of the present invention also demonstrates cleaning sense and the advantages of good skin tactility and the foaminess of improvement, they are suitable for cleaning simultaneously and conditioning skin and/or hair, for example can foam bathing goods, shower product, skin cleaner, hands, face and forms such as clean body agent, shampoo use.

Background of invention

Gentle cosmetic composition must satisfy the multiple standards that comprises cleaning power, foaminess and mildness/low irritant/advantages of good skin, hair and eye mucosa sensation.Skin is by covering and protecting several confluent monolayer cells of lower-hierarchy to constitute.Keratin and collagen fiber albumen form its structural framework.The outermost layer of these layers is called as horny layer.Equally, hair also has the protective garments around hair fiber, is called as cuticula (horny layer).Anion surfactant can penetrate cutin tunic and cuticula, and destroys the integrity of film by degreasing, makes it lose barrier action and water retaining function.

This interference effect for skin and hair protecting film can cause coarse skin sense and eye to stimulate, and finally impels surfactant to cause immunoreation and produces stimulation.

Ideal cosmetic cleaning agent is cleaning skin or hair leniently, and should not make hair and skin defat and/or dry, does not stimulate the eye mucosa or can not make skin tight after daily use simultaneously.Great majority foaming soap, shower and bathing product, shampoo and block cleaning product can not satisfy these requirements.

Known some synthetic surfactant is gentle.But when preparation shampoo and personal cleanser, a major defect of the synthetic surfactant system that some is gentle is to have the cleaning sense of not liking for some client that can be described as " smooth " or " not having puckery sense ".On the other hand, some surfactant for example use of potassium laurate can produce the cleaning sense of " puckery sense ", but damages clinical skin mildness.The both of these case explanation must be carried out balance between cleaning sense and mildness when selecting suitable surfactant.

Therefore, still need to have the personal cleaning compositions that " puckery sense " cleans sense, said composition is removed has good product attribute, for example foams, cleans, stablizes, outside thickening, rheological characteristic and the skin usability, also has the advantages of good skin mildness.

Also wish to make the skin care activity composition offer skin from personal cleaning compositions.This class skin care activity composition comprises, for example sunscreen, antimicrobial and vitamin.Past attempts attempts providing skin care actives from personal cleaning compositions.Yet, based on these active substance capacities be deposited on the skin could the generation effect viewpoint, these trials always can not succeedd.

WO 97/16168 discloses a kind of personal cleaning compositions; contain (a) surfactant; (b) hydrophobic active composition; be selected from: skin conditioning agent, skin care and antibacterial; (c) composition of hydrocarbonaceous and (d) cationic polymer are selected (c) and amount (d) so that component (b) is higher than (c) and (d) independent adduction to the effect of skin.

Unexpectedly find now, by some water-insoluble oil, for example some poly ﹠ Alpha ,-olefin oil and some hydrophobicity skin care activity composition and gentleness, water soluble surfactant active's system combines, and can be provided at the personal cleaning compositions of the deposition with improvement of sending out the cleaning sense puckery and also having the hydrophobicity skin care actives good gentle characteristic the time.

Summary of the invention

The invention provides a kind of liquid personal cleansing composition of washing off, contain:

(a) water;

(b) water soluble surfactant active of about 1%-about 60% (weight);

(c) water-insoluble oil is selected from the highly branched poly alpha olefin of following formula

R wherein ¹Be H or C ₁-C ₂₀Alkyl, R ⁴Be C ₁-C ₂₀Alkyl, R ²Be H or C ₁-C ₂₀Alkyl, R ³Be C ₃-C ₂₀Alkyl, preferred C ₅-C ₂₀Alkyl, n are the integer of 0-3 and the integer that m is 1-1000, and the about 1000-of number-average molecular weight about 25000; With

(d) hydrophobicity skin care activity composition is selected from antimicrobial, sunscreen, vitamin, aromatic oil, anthelmintic, antifungal and their mixture, and wherein the ClogP value of hydrophobicity skin care activity composition is greater than 3.

Compositions of the present invention has been improved the deposition of skin care activity composition in to the skin abnormality gentleness, have the cleaning sense of " sending out puckery ".

Except as otherwise noted, all concentration of the present invention and ratio are all in the weight of Cleasing compositions.Except as otherwise noted, the chain length of surfactant is also based on weight average chain length.

Detailed Description Of The Invention

The liquid cleansing composition of this paper contains water, surfactant, hydrophobicity skin care activity composition and some water-insoluble oil, will further describe them below.

The term that this paper adopts " cleans sense " and is meant with after the Cleasing compositions cleaning sensation of skin the flush away foam process from skin.The type of the cleaning sense that compositions of the present invention produces can be described with following term: for example " puckery sense " clean sense, " soap sample " and clean sense and " not smooth " or " sticking " and (non-slimy) clean sense.This " puckery sense ", " soap sample ", " not smooth " or " sticking " are cleaned to feel increasing by the friction between hands and the skin in the foam process on the cleaning skin and discover.
