Description

一种化妆品用花朵及其保色方法 技术领域
本发明涉及化妆品领域，尤其涉及一种化妆品用花朵及其保色方法。
背景技术
近年来，随着人们生活水平的提高、皮肤保健意识的提高和科技的发展，在绿色、环保、崇尚自然及回归自然理念的推动下，天然植物类化妆品越来越受到消费者的钟爱。与传统化妆品相比较，植物活性成分是天然物质，分子更小，更容易被皮肤吸收，而且不会在体内产生沉积，长期使用无副作用。同时在天然植物概念的推崇下，涌现了添加部分植物花瓣的化妆品，如花瓣水、花瓣面膜、花瓣洁面乳等，使植物花瓣的活性和新颖漂亮的外观得到了最大限度的保存、延伸。美容产品一方面是有效成分的发挥带来的美容效果，另一方面是心理愉悦带来的心理美容，具有良好形态和色泽的有形玫瑰花瓣产品能带来良好的视觉享受，激发消费者的心理愉悦，从而带来美容效果。
现有的花瓣保鲜保色技术多应用于观赏领域，在花茶产品中也有涉及到干花的保色。而在化妆品中直接应用整支花朵的产品较少，多为鲜花花瓣的直接添加和处理后的干花添加，或者将鲜花水煮后加入，并不能达到鲜花在化妆品中保鲜保色的效果。
CN102688166A公开了一种化妆品用花瓣的制作方法，其中包括将干花瓣加入去离子水高温加热灭菌，氢氧化钾水溶液脱色，放入柠檬酸水中搅拌3-5分钟后，再于防腐剂水溶液中保存。该方法使用干花瓣为原料，花瓣易碎、不新鲜，活性成分流失严重，高温水煮和氢氧化钾处理均会导致花瓣的严重脱色，应用于化妆品中，不能达到保色保鲜的效果。
CN103263372A公开了一种天然花瓣和采用该天然花瓣的化妆品，其中将天然花瓣醇煮、水煮、烘焙。该方法使用干花瓣为原料，其实是对花瓣进行二次加工处理，花瓣破损大；高温不仅耗能而且破坏了新鲜花瓣中耐温性差的活性成分，烘焙的干花瓣在存储运输中易破损，容易滋生微生物，为化妆品带来安全隐患。
综上所述，现有技术存在如下的诸多问题：
1、鲜花含水分、泥沙、微生物较多，在应用时容易发生霉变；
2、为了应对霉变加入大量防腐剂，刺激性强，不符合绿色化妆品的理念；
3、将鲜花水煮或者添加干花，前者导致花瓣掉色，失去相应的色泽及活性，后者花瓣脆容易碎，在化妆品油性体系中不能达到舒展、有韧性的效果；
4、单独添加花瓣，添加过程中容易使花瓣卷皱，不能维持良好形态。
因此，研发一种化妆品用花朵的保色方法，以适用于在全油体系化妆品中添加鲜花，保持花朵颜色、形状等特性，具有巨大的市场价值及广阔的应用前景。
发明内容
针对现有技术的不足及实际的需求，本发明提供一种化妆品用花朵及其保色方法，通过优化工艺流程，选用适宜浓度的护色液及溶解液，各步骤协同增效，使得鲜花在全油体系中保持原有色泽和姿态，保质期长，稳定性高，品质良好。

由表15可知，实施例1-3的技术方案在本发明提供的范围内，制备得到的化妆品用花朵的微生物含量保持在较低范围内，优于大部分现有技术、溶液浓度超过本发明提供的范围的对比例以及缺少组分或步骤的对比例。
综上所述，本发明提供的护色方法通过优化工艺流程，采用质量浓度为0.4-0.8％的氯化钠和质量浓度为0.4-3％的柠檬酸浸泡护色，并用乙醇溶解花朵中的有机物，各步骤各条件协同增效，缺一不可，共同处理后得到在全油体系中保持原有色泽和姿态的鲜花，保质期长，稳定性高，品质良好，具备广阔的应用前景和市场价值。其中，实施例1的方法制备得到的化妆品用花朵的效果最好，色泽光亮，脱色程度轻，形状完整、舒展，质感柔软，无变质现象，而任何条件浓度超过本发明提供的范围或者缺少相应处理步骤的对比例制备得到的花朵均无法满足生产应用要求，保质期短，色泽暗黄有皱缩。
申请人声明，本发明通过上述实施例来说明本发明的详细方法，但本发明并不局限于上述详细方法，即不意味着本发明必须依赖上述详细方法才能实施。所属技术领域的技术人员应该明了，对本发明的任何改进，对本发明产品各原料的等效替换及辅助成分的添加、具体方式的选择等，均落在本发明的保护范围和公开范围之内。
